Personality disorders are a group of mental disturbances defined by the fourth edition, text revision (2000) of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) as "enduring pattern[s] of inner experience and behavior" that are sufficiently rigid and deep-seated to bring a person into repeated conflicts with his or her social and occupational environment. DSM-IV specifies that these dysfunctional patterns must be regarded as nonconforming or deviant by the person's culture, and cause significant emotional pain and/or difficulties in relationships and occupational performance. In addition, the patient usually sees the disorder as being consistent with his or her self-image (ego-syntonic) and may blame others for his or her social, educational, or work-related problems.
To meet the diagnosis of personality disorder, which is sometimes called character disorder, the patient's problematic behaviors must appear in two or more of the following areas:
- perception and interpretation of the self and other people
- intensity and duration of feelings and their appropriateness to situations
- relationships with others
- ability to control impulses
Personality disorders have their onset in late adolescence or early adulthood. Doctors rarely give a diagnosis of personality disorder to children on the grounds that children's personalities are still in the process of formation and may change considerably by the time they are in their late teens. In retrospect, however, many individuals with personality disorders could be judged to have shown evidence of the problems in childhood.
It is difficult to give close estimates of the percentage of the population that has personality disorders. Patients with certain personality disorders, including antisocial and borderline disorders, are more likely to get into trouble with the law or otherwise attract attention than are patients whose disorders chiefly affect their capacity for intimacy. On the other hand, some patients, such as those with narcissistic or obsessive-compulsive personality disorders, may be outwardly successful because their symptoms are useful within their particular occupations. It has, however, been estimated that about 15% of the general population of the United States has a personality disorder, with higher rates in poor or troubled neighborhoods. The rate of personality disorders among patients in psychiatric treatment is between 30% and 50%. It is possible for patients to have a so-called dual diagnosis; for example, they may have more than one personality disorder, or a personality disorder together with a substance-abuse problem.
By contrast, DSM-IV classifies personality disorders into three clusters based on symptom similarities:
- Cluster A (paranoid, schizoid, schizotypal): Patients appear odd or eccentric to others.
- Cluster B (antisocial, borderline, histrionic, narcissistic): Patients appear overly emotional, unstable, or self-dramatizing to others.
- Cluster C (avoidant, dependent, obsessive-compulsive): Patients appear tense and anxiety-ridden to others.
The DSM-IV clustering system does not mean that all patients can be fitted neatly into one of the three clusters. It is possible for patients to have symptoms of more than one personality disorder or to have symptoms from different clusters.
Some psychiatrists maintain that the DSM-IV classification is inadequate and should be expanded to include three additional categories: passive-aggressive personality disorder, characterized by a need to control or punish others through frustrating them or sabotaging plans; cyclothymic personality disorder, characterized by intense mood swings alternating between high spirits and moroseness or gloom; and depressive personality disorder, characterized by a negative and pessimistic approach to life.
Since the criteria for personality disorders include friction or conflict between the patient and his or her social environment, these syndromes are open to redefinition as societies change. Successive editions of DSM have tried to be sensitive to cultural differences, including changes over time, when defining personality disorders. One category that had been proposed for DSM-III-R, self-defeating personality disorder, was excluded from DSM-IV on the grounds that its definition reflected prejudice against women. DSM-IV recommends that doctors take a patient's background, especially recent immigration, into account before deciding that he or she has a personality disorder. One criticism that has been made of the general category of personality disorder is that it is based on Western notions of individual uniqueness. Its applicability to people from cultures with different definitions of human personhood is thus open to question. Furthermore, even within a culture, it can be difficult to define the limits of "normalcy."
The personality disorders defined by DSM-IV are as follows:
Patients with paranoid personality disorder are characterized by suspiciousness and a belief that others are out to harm or cheat them. They have problems with intimacy and may join cults or groups with paranoid belief systems. Some are litigious, bringing lawsuits against those they believe have wronged them. Although not ordinarily delusional, these patients may develop psychotic symptoms under severe stress. It is estimated that 0.5-2.5% of the general population meet the criteria for paranoid personality disorder.
Schizoid patients are perceived by others as "loners" without close family relationships or social contacts. Indeed, they are aloof and really do prefer to be alone. They may appear cold to others because they rarely display strong emotions. They may, however, be successful in occupations that do not require personal interaction. About 2% of the general population has this disorder. It is slightly more common in men than in women.
Patients diagnosed as schizotypal are often considered odd or eccentric because they pay little attention to their clothing and sometimes have peculiar speech mannerisms. They are socially isolated and uncomfortable in parties or other social gatherings. In addition, people with schizotypal personality disorder often have oddities of thought, including "magical" beliefs or peculiar ideas (for example, a belief in telepathy or UFOs) that are outside of their cultural norms. It is thought that 3% of the general population has schizotypal personality disorder. It is slightly more common in males. Schizotypal disorder should not be confused with schizophrenia, although there is some evidence that the disorders are genetically related.
Patients with antisocial personality disorder are sometimes referred to as sociopaths or psychopaths. They are characterized by lying, manipulativeness, and a selfish disregard for the rights of others; some may act impulsively. People with antisocial personality disorder are frequently chemically dependent and sexually promiscuous. It is estimated that 3% of males in the general population and 1% of females have antisocial personality disorder.
Patients with borderline personality disorder (BPD) are highly unstable, with wide mood swings, a history of intense but stormy relationships, impulsive behavior, and confusion about career goals, personal values, or sexual orientation. These often highly conflictual ideas may correspond to an even deeper confusion about their sense of self (identity). People with BPD frequently cut or burn themselves, or threaten or attempt suicide. Many of these patients have histories of severe childhood abuse or neglect. About 2% of the general population have BPD; 75% of these patients are female.
Patients diagnosed with this disorder impress others as overly emotional, overly dramatic, and hungry for attention. They may be flirtatious or seductive as a way of drawing attention to themselves, yet they are emotionally shallow. Histrionic patients often live in a romantic fantasy world and are easily bored with routine. About 2-3% of the population is thought to have this disorder. Although historically the disorder has been more associated with womenin clinical settings, there may be bias toward diagnosing women with the histrionic personality disorder.
Narcissistic patients are characterized by self-importance, a craving for admiration, and exploitative attitudes toward others. They have unrealistically inflated views of their talents and accomplishments, and may become extremely angry if they are criticized or outshone by others. Narcissists may be professionally successful but rarely have long-lasting intimate relationships. Fewer than 1% of the population has this disorder; about 75% of those diagnosed with it are male.
Patients with avoidant personality disorder are fearful of rejection and shy away from situations or occupations that might expose their supposed inadequacy. They may reject opportunities to develop close relationships because of their fears of criticism or humiliation. Patients with this personality disorder are often diagnosed with dependent personality disorder as well. Many also fit the criteria for social phobia. Between 0.5-1.0% of the population have avoidant personality disorder.
Dependent patients are afraid of being on their own and typically develop submissive or compliant behaviors in order to avoid displeasing people. They are afraid to question authority and often ask others for guidance or direction. Dependent personality disorder is diagnosed more often in women, but it has been suggested that this finding reflects social pressures on women to conform to gender stereotyping or bias on the part of clinicians.
Patients diagnosed with this disorder are preoccupied with keeping order, attaining perfection, and maintaining mental and interpersonal control. They may spend a great deal of time adhering to plans, schedules, or rules from which they will not deviate, even at the expense of openness, flexibility, and efficiency. These patients are often unable to relax and may become "workaholics." They may have problems in employment as well as in intimate relationships because they are very stiff and formal, and insist on doing everything their way. About 1% of the population has obsessive-compulsive personality disorder; the male/female ratio is about 2:1.
Causes and symptoms
Personality disorders are thought to result from a bad interface, so to speak, between a child's temperament and character on one hand and his or her family environment on the other. Temperament can be defined as a person's innate or biologically shaped basic disposition. Human infants vary in their sensitivity to light or noise, their level of physical activity, their adaptability to schedules, and similar traits. Even such traits as shyness or novelty-seeking may be at least in part determined by the biology of the brain and the genes one inherits.
Character is defined as the set of attitudes and behavior patterns that the individual acquires or learns over time. It includes such personal qualities as work and study habits, moral convictions, neatness or cleanliness, and consideration of others. Since children must learn to adapt to their specific families, they may develop personality disorders in the course of struggling to survive psychologically in disturbed or stressful families. For example, nervous or high-strung parents might be unhappy with a baby who is very active and try to restrain him or her at every opportunity. The child might then develop an avoidant personality disorder as the outcome of coping with constant frustration and parental disapproval. As another example, child abuse is believed to play a role in shaping borderline personality disorder. One reason that some therapists use the term developmental damage instead of personality disorder is that it takes the presumed source of the person's problems into account.
Some patients with personality disorders come from families that appear to be stable and healthy. It has been suggested that these patients are biologically hypersensitive to normal family stress levels. Levels of the brain chemical (neurotransmitter) dopamine may influence a person's level of novelty-seeking, and serotonin levels may influence aggression.
Other factors that have been cited as affecting children's personality development are the mass media and social or group hysteria, particularly after the events of September 11, 2001. Cases of so-called mass sociogenic illness have been identified, in which a group of children began to vomit or have other physical symptoms brought on in response to an imaginary threat. In two such cases, the children were reacting to the suggestion that toxic fumes were spreading through their school. Some authors believe that overly frequent or age-inappropriate discussions of terrorist attacks or bioterrorism may make children more susceptible to sociogenic illness as well as other distortions of personality.
Diagnosis of personality disorders is complicated by the fact that affected persons rarely seek help until they are in serious trouble or until their families (or the law) pressure them to get treatment. The reason for this slowness is that the problematic traits are so deeply entrenched that they seem normal (ego-syntonic) to the patient. Diagnosis of a personality disorder depends in part on the patient's age. Although personality disorders originate during the childhood years, they are considered adult disorders. Some patients, in fact, are not diagnosed until late in life because their symptoms had been modified by the demands of their job or by marriage. After retirement or the spouse's death, however, these patients' personality disorders become fully apparent. In general, however, if the onset of the patient's problem is in mid- or late-life, the doctor will rule out substance abuse or personality change caused by medical or neurological problems before considering the diagnosis of a personality disorder. It is unusual for people to develop personality disorders "out of the blue" in mid-life.
There are no tests that can provide a definitive diagnosis of personality disorder. Most doctors will evaluate a patient on the basis of several sources of information collected over a period of time in order to determine how long the patient has been having difficulties, how many areas of life are affected, and how severe the dysfunction is. These sources of information may include:
The doctor may schedule two or three interviews with the patient, spaced over several weeks or months, in order to rule out an adjustment disorder caused by job loss, bereavement, or a similar problem. An office interview allows the doctor to form an impression of the patient's overall personality as well as obtain information about his or her occupation and family. During the interview, the doctor will note the patient's appearance, tone of voice, body language, eye contact, and other important non-verbal signals, as well as the content of the conversation. In some cases, the doctor may contact other people (family members, employers, close friends) who know the patient well in order to assess the accuracy of the patient's perception of his or her difficulties. It is quite common for people with personality disorders to have distorted views of their situations or to be unaware of the impact of their behavior on others.
Doctors use psychologic testing to help in the diagnosis of a personality disorder. Most of these tests require interpretation by a professional with specialized training. Doctors usually refer patients to a clinical psychologist for this type of test.
PERSONALITY INVENTORIES. Personality inventories are tests with true/false or yes/no answers that can be used to compare the patient's scores with those of people with known personality distortions. The single most commonly used test of this type is the Minnesota Multiphasic Personality Inventory, or MMPI. Another test that is often used is the Millon Clinical Multiaxial Inventory, or MCMI.
PROJECTIVE TESTS. Projective tests are unstructured. Unstructured means that instead of giving one-word answers to questions, the patient is asked to talk at some length about a picture that the psychologist has shown him or her, or to supply an ending for the beginning of a story. Projective tests allow the clinician to assess the patient's patterns of thinking, fantasies, worries or anxieties, moral concerns, values, and habits. Common projective tests include the Rorschach, in which the patient responds to a set of ten inkblots; and the Thematic Apperception Test (TAT), in which the patient is shown drawings of people in different situations and then tells a story about the picture.
At one time psychiatrists thought that personality disorders did not respond very well to treatment. This opinion was derived from the notion that human personality is fixed for life once it has been molded in childhood, and from the belief among people with personality disorders that their own views and behaviors are correct, and that others are the ones at fault. More recently, however, doctors have recognized that humans can continue to grow and change throughout life. Most patients with personality disorders are now considered to be treatable, although the degree of improvement may vary. The type of treatment recommended depends on the personality characteristics associated with the specific disorder.
Inpatient treatment is rarely required for patients with personality disorders, with two major exceptions: borderline patients who are threatening suicide or suffering from drug or alcohol withdrawal; and patients with paranoid personality disorder who are having psychotic symptoms.
Psychoanalytic psychotherapy is suggested for patients who can benefit from insight-oriented treatment. These patients typically include those with dependent, obsessive-compulsive, and avoidant personality disorders. Doctors usually recommend individual psychotherapy for narcissistic and borderline patients, but often refer these patients to therapists with specialized training in these disorders. Psychotherapeutic treatment for personality disorders may take as long as three to five years.
Insight-oriented approaches are not recommended for patients with paranoid or antisocial personality disorders. These patients are likely to resent the therapist and see him or her as trying to control or dominate them.
Supportive therapy is regarded as the most helpful form of psychotherapy for patients with schizoid personality disorder.
Cognitive-behavioral approaches are often recommended for patients with avoidant or dependent personality disorders. Patients in these groups typically have mistaken beliefs about their competence or likableness. These assumptions can be successfully challenged by cognitive-behavioral methods. More recently, Aaron Beck and his coworkers have successfully extended their approach to cognitive therapy to all ten personality disorders as defined by DSM-IV.
Group therapy is frequently useful for patients with schizoid or avoidant personality disorders because it helps them to break out of their social isolation. It has also been recommended for patients with histrionic and antisocial personality disorders. These patients tend to act out, and pressure from peers in group treatment can motivate them to change. Because patients with antisocial personality disorder can destabilize groups that include people with other disorders, it is usually best if these people meet exclusively with others who have APD (in homogeneous groups).
Family therapy may be suggested for patients whose personality disorders cause serious problems for members of their families. It is also sometimes recommended for borderline patients from overinvolved or possessive families.
Medications may be prescribed for patients with specific personality disorders. The type of medication depends on the disorder. In general, however, patients with personality disorders are helped only moderately by medications.
ANTIPSYCHOTIC DRUGS. Antipsychotic drugs, such as haloperidol (Haldol), may be given to patients with paranoid personality disorder if they are having brief psychotic episodes. Patients with borderline or schizotypal personality disorder are sometimes given antipsychotic drugs in low doses; however, the efficacy of these drugs in treating personality disorder is less clear than in schizophrenia.
MOOD STABILIZERS. Carbamazepine (Tegretol) is a drug that is commonly used to treat seizures, but is also helpful for borderline patients with rage outbursts and similar behavioral problems. Lithium and valproate may also be used as mood stabilizers, especially among people with borderline personality disorder.
ANTIDEPRESSANTS AND ANTI-ANXIETY MEDICATIONS. Medications in these categories are sometimes prescribed for patients with schizoid personality disorder to help them manage anxiety symptoms while they are in psychotherapy. Antidepressants are also commonly used to treat people with borderline personality disorder.
Treatment with medications is not recommended for patients with avoidant, histrionic, dependent, or narcissistic personality disorders. The use of potentially addictive medications should be avoided in people with borderline or antisocial personality disorders. However, some avoidant patients who also have social phobia may benefit from monoamine oxidase inhibitors (MAO inhibitors), a particular class of antidepressant.
The prognosis for recovery depends in part on the specific disorder. Although some patients improve as they grow older and have positive experiences in life, personality disorders are generally life-long disturbances with periods of worsening (exacerbations) and periods of improvement (remissions). Others, particularly schizoid patients, have better prognoses if they are given appropriate treatment. Beck and his coworkers estimate that effective cognitive therapy with patients with personality disorders takes two to three years on average. Patients with paranoid personality disorder are at some risk for developing delusional disorders or schizophrenia.
The personality disorders with the poorest prognoses are the antisocial and the borderline. Borderline patients are at high risk for developing substance abuse disorders or bulimia. About 80% of hospitalized borderline patients attempt suicide at some point during treatment, and about 5% succeed in committing suicide. Borderline patients are also the most likely to sue their mental health professional for malpractice.
The most effective preventive strategy for personality disorders is early identification and treatment of children at risk. High-risk groups include abused children, children from troubled families, children with close relatives diagnosed with personality disorders, children of substance abusers, and children who grow up in cults or extremist political groups.
Character— An individual's set of emotional, cognitive, and behavioral patterns learned and accumulated over time.
Character disorder— Another name for personality disorder.
Cognitive therapy— A form of psychotherapy that focuses on changing people's patterns of emotional reaction by correcting distorted patterns of thinking and perception.
Developmental damage— A term that some therapists prefer to personality disorder, on the grounds that it is more respectful of the patient's capacity for growth and change.
Ego-syntonic— Consistent with one's sense of self, as opposed to ego-alien or dystonic (foreign to one's sense of self). Ego-syntonic traits typify patients with personality disorders.
Neuroleptic— Another name for older antipsychotic medications, such as haloperidol. The term does not apply to such newer atypical agents as clozapine (Clozaril).
Personality— The organized pattern of behaviors and attitudes that makes a human being distinctive. Personality is formed by the ongoing interaction of temperament, character, and environment.
Projective tests— Psychological tests that probe into personality by obtaining open-ended responses to such materials as pictures or stories. Projective tests are often used to evaluate patients with personality disorders.
Rorschach test— A well-known projective test that requires the patient to describe what he or she sees in each of 10 inkblots. It is named for the Swiss psychiatrist who invented it.
Temperament— A person's natural or genetically determined disposition.

Personality disorders (PD) are a group of psychiatric conditions characterized by experience and behavior patterns that cause serious problems with respect to any two of the following: thinking, mood, personal relations, and the control of impulses.
Most personality disorders are associated with problems in personal development and character which peak during adolescence and are then defined as personality disorders. Children and adolescents with a personality disorder have great difficulty dealing with others. They tend to be inflexible, rigid, with inadequate response to the changes and demands of life. They have a narrow view of the world and find it hard to participate in social activities. There are many formally identified personality disorders, each with its own types of associated behaviors. Most PDs, however, fall into three distinct categories or clusters, namely: cluster A, which includes disorders characterized by odd or eccentric behavior; cluster B, which includes disorders marked by dramatic, emotional or erratic behavior; and cluster C, which includes disorders accompanied by anxious and fearful behavior. The most common disorders in each cluster are given below.
Cluster A disorders
These disorders include the following:
- Schizoid personality disorder. Schizoid personalities are introverted, withdrawn, solitary, emotionally cold, and distant. Often absorbed with their own thoughts and feelings, they fear closeness and intimacy with others. People suffering from schizoid personality tend to be more daydreamers than practical action takers, often living "in a world of their own."
- Paranoid personality disorder. Paranoid personalities interpret the actions of others as deliberately threatening or demeaning. People with paranoid personality disorder are untrusting, unforgiving, and often resort to angry or aggressive outbursts without justification because they see others as unfaithful, disloyal, or dishonest. Paranoid personalities are often jealous, guarded, secretive, and scheming, and may appear to be emotionally "cold" or excessively serious.
- Schizotypal personality disorder. Schizotypal personalities tend to have odd or eccentric manners of speaking or dressing. They often have strange, outlandish, or paranoid beliefs and thoughts. People with schizotypal personality disorder have difficulties bonding with others and experience extreme anxiety in social situations. They tend to react inappropriately or not react at all during a conversation, or they may talk to themselves. They also have delusions characterized by "magical thinking," for example, by saying that they can foretell the future or read other people's minds.
Cluster B disorders
Cluster B disorders include the following:
- Antisocial personality disorder . Antisocial personalities typically ignore the normal rules of social behavior. These individuals are impulsive, irresponsible, and callous. They often have a history of violent and irresponsible behavior, aggressive and even violent relationships. They have no respect for other people and feel no remorse about the effects of their behavior on others. Antisocial personalities are at high risk for substance abuse, since it helps them to relieve tension, irritability, and boredom.
- Borderline personality disorder. Borderline personalities are unstable in interpersonal relationships, behavior, mood, and self-image. They are prone to sudden and extreme mood changes, stormy relationships, unpredictable and often self-destructive behavior. These personalities have great difficulty with their own sense of identity and often experience the world in extremes, viewing experiences and others as either "black" or "white." They often form intense personal attachments only to quickly dissolve them over a perceived offense. Fears of abandonment and rejection often lead to an excessive dependency on others. Self-mutilation or suicidal threats may be used to get attention or manipulate others. Impulsive actions, persistent feelings of boredom or emptiness, and intense anger outbursts are other traits of this disorder.
- Narcissistic personality disorder. Narcissistic personalities tend to have an exaggerated sense of self-importance, and are absorbed by fantasies of unlimited success. They also seek constant attention, and are oversensitive to failure, often complaining about multiple physical disorders. They also tend to be prone to extreme mood swings between self-admiration and insecurity, and tend to exploit interpersonal relationships.
Cluster C disorders
Cluster C disorders include the following:
- Avoidant personality disorder. Avoidant personalities are often fearful of rejection and unwilling to become involved with others. They are characterized by excessive social discomfort, shyness , fear of criticism, and avoidance of social activities that involve interpersonal contact. They are afraid of saying something considered foolish by others and are deeply hurt by any disapproval from others. They tend to have no close relationships outside the family circle and are upset at their inability to form meaningful relationships.
- Dependent personality disorder . As the name implies, dependent personalities exhibit a pattern of dependent and submissive behavior, relying on others to make decisions for them. They fear rejection, need constant reassurance and advice, and are oversensitive to criticism or disapproval. They feel uncomfortable and helpless if they are alone and can be devastated when a close relationship ends. Typically lacking in self-confidence, the dependent personality rarely initiates projects or does things independently.
- Compulsive personality disorder. Compulsive personalities are conscientious, reliable, dependable, orderly, and methodical, but with an inflexibility that often makes them incapable of adapting to changing circumstances. They have such high standards of achievement that they constantly strive for perfection. Never satisfied with their performance or with that of others, they take on more and more responsibilities. They also pay excessive attention to detail, which makes it very hard for them to make decisions and complete tasks. When their feelings are not under strict control, when events are unpredictable, or when they must rely on others, compulsive personalities often feel a sense of isolation and helplessness.
In 2001 to 2002, fully 16.4 million Americans (7.9% of all adults) had obsessive-compulsive personality disorder; 9.2 million (4.4%) had paranoid personality disorder; 7.6 million (3.6%) had antisocial personality disorder; 6.5 million (3.1%) had schizoid personality disorder; 4.9 million (2.4%) had avoidant personality disorder; and 1.0 million (0.5%) had dependent personality disorder. According to the National Institutes of Health, nearly 31 million Americans meet criteria for at least one personality disorder. A 2004 survey showed that nearly 14.8 percent of adult Americans met diagnostic criteria for personality disorders as defined by the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders. The risk of having avoidant, dependent, and paranoid personality disorders is greater for females than males, whereas risk of having antisocial personality disorder is greater for males than females. There are no gender differences in the risk of having compulsive or schizoid personality disorders. In general, other risk factors contributing to the emergence of personality disorders include being Native American or African American; being a young adult; having a low socioeconomic status; and having any other status than married.
Causes and symptoms
The exact cause of personality disorders is unknown. However, evidence points to genetic and environmental factors such as a history of personality disorders in the family. Some experts believe that traumatic events occurring in early childhood exert a crucial influence upon behavior later in life. Others propose that people are genetically predisposed to personality disorders or that they have an underlying biological disturbance (anatomical, electrical, or neurochemical).
Symptoms vary widely depending on the specific type of PD, but according to the American Psychiatric Association, individuals with personality disorders have most of the following symptoms in common:
- self-centeredness that manifests itself through a "me-first," self-preoccupied attitude
- lack of individual accountability that results in a "victim mentality" and blaming others for their problems
- lack of empathy and caring
- manipulative and exploitative behavior
- unhappiness, suffering from depression, and other mood and anxiety disorders
- vulnerability to other mental disorders
- distorted or superficial understanding of self and others' perceptions that results in being unable to see how objectionable, unacceptable, and disagreeable their behavior is
- self-destructive behavior
- socially maladaptive, changing the "rules of the game," or otherwise influencing the external world to conform to their own needs
When to call the doctor
An appointment should be made with a healthcare provider or a mental health professional if a child has persistent symptoms of a personality disorder. Parents are often concerned about their child's emotional health or behavior, but they do not know where to start to get help. The mental health system can also be complicated and difficult for parents to understand. When worried about their child's behavior, parents can start by talking to the child's pediatrician or family physician about their concerns. Personality disorders require treatment and parents should try to find a mental health professional with advanced training and experience with children, adolescents, and families. Parents should always ask about the professional's training and experience. It is also very important to find a good match between child, family, and the mental health professional.
The character of a person is shown through his or her personality, by the way the person thinks, feels, and behaves. When the behavior is inflexible, maladaptive, and antisocial, then that individual is diagnosed with a personality disorder. Personality disorders are diagnosed following a psychological evaluation that records the history and severity of the symptoms. A personality disorder must fulfill several criteria. A deeply ingrained, inflexible pattern of relating, perceiving, and thinking that is serious enough to cause distress or impaired functioning defines a personality disorder. Personality disorders are usually recognizable by adolescence or earlier, continue throughout adulthood, and become less obvious in middle age.
There are many types of help available for the different personality disorders. Treatment may include individual, group, or family psychotherapy. Medications, prescribed by a patient's physician, may also be helpful in relieving some of the symptoms of personality disorders, such as problems with anxiety and delusions. Psychotherapy is a form of treatment designed to help children and families understand and resolve the problems due to PD and modify the inappropriate behavior. In some cases a combination of medication with psychotherapy may be more effective. PD psychotherapy focuses on helping patients see the unconscious conflicts that are causing their disorder. It also helps them become more flexible and is aimed at reducing the behavior patterns that interfere with everyday living. In psychotherapy, patients have the opportunity to learn to recognize the effects of their behavior on others. The different types of psychotherapies available to children and adolescents include the following:.
- Cognitive behavior therapy (CBT). CBT is focused on improving a child's moods and behavior by examining confused or distorted patterns of thinking. With CBT, the child learns that thoughts cause feelings and moods that can influence behavior. For example, if a child has problematic behavior patterns, the therapist seeks to identify the underlying thinking that is causing them. The therapist then helps the child replace this thinking with thoughts that result in more appropriate feelings and behaviors.
- Dialectical behavior therapy (DBT). DBT is used to treat older adolescents with suicidal thoughts or who intentionally engage in self-destructive behavior or who have borderline personality disorder. DBT teaches how to take responsibility for one's problems and how to deal with conflict and negative feelings. DBT often involves a combination of group and individual sessions.
- Family therapy . This therapy approach is designed to help the family unit function in more positive and constructive ways by exploring patterns of communication and providing support and education. Family therapy sessions can include the child or adolescent along with parents and siblings.
- Group therapy (GT). GT uses group dynamics and peer interactions to increase understanding, communication, and improve social skills.
- Play therapy. This type of therapy is directed at helping younger children. It involves the use of toys , blocks, dolls, puppets, drawings , and games to help the child recognize, identify, and verbalize feelings. The psychotherapist observes how the child uses play materials and identifies themes or patterns to understand the child's problems. Through a combination of talk and play the child has an opportunity to better understand conflicts, feelings, and behavior.
Alternative treatments are available for personality disorders and most are complementary to conventional psychotherapy. They include the following:
- Coloring therapy. CT uses the activity of coloring as a self-help medium. While a person colors (with felt tipped markers, colored pens, pencils, etc.) a state of consciousness similar to meditation occurs. The approach is based on how people speak to themselves on the "inside." During a coloring session, people are asked to listen to the thoughts going on in their minds so as to become aware of where their thoughts, feelings, and opinions come from.
- Creative arts therapies. These therapies include art therapy, dance/movement therapy, drama therapy, music therapy, poetry therapy, and psychodrama. They use arts and creative processes to promote health, communication, and expression; they encourage the integration of physical, emotional, cognitive, and social functioning while enhancing self-awareness and facilitating change.
- Neurolinguistic programming. NLP is a method of examining the way a person thinks and acts through language and using this knowledge to effect change.
The notion that foods and nutrients influence brain function and behavior generated in the early 2000s widespread interest in the general public and in the scientific community. However, the evaluation data are still ambiguous when it comes to establishing a direct link between personality disorders and diet, aside from recommending the avoidance of alcoholic and stimulant beverages.
The PD outlook varies. Some personality disorders diminish during middle age without any treatment, while others persist throughout life despite treatment.
The prevention of personality disorders is an area surrounded with pessimism and controversy. Many mental health specialists believe that these disorders are untreatable, that individuals with personality disorder have little capacity for change; therefore not surprisingly, they remain skeptical about prevention prospects. However, even though the innate temperament of a person cannot be modified, understanding the factors that influence the development of personality disorders (such as genetic risks and environmental factors) may help prevention. Accordingly, some mental health professionals advocate primary prevention steps, which should include education of parents and primary healthcare workers, as well as early psychotherapy and protection of traumatized children, which can be carried out by child developing services. Some evidence suggests that traditional doctor-patient relationships are of much less value than programs which enable parents to see their own role as crucial and their own actions as able to bring changes for the better in their child's behavior. High quality parenting plays a critical role in child development and, thus, in the prevention of personality disorders.
Understanding personality disorders can be challenging for parents as well as for children. During the last third of the twentieth century, great advances were made in the areas of diagnosis and treatment of personality disorders. Parents can help children understand that these are real illnesses that can be treated. In order for parents to talk with a child about a personality disorder, they must be knowledgeable of the subject. Parents may have to do some homework to become better informed. They should have a basic understanding and answers to questions such as what are personality disorders, who gets them, what causes them, how are diagnoses made, and what treatments are available. When explaining to a child about how personality disorders affect a person, it may be helpful to explain that feelings of anxiety, worry, and irritability are common for most people. However, when these feelings get very intense, last for a long period of time, and begin to interfere with school and relationships, it may be a sign of a personality disorder that can, however, be treated.
A child's personality disorder often causes disruption to both the parents' and the child's world. Parents may have difficulty being objective. They may blame themselves or worry that others such as teachers or family members will blame them. Recognizing these feelings and seeking the help of professional care providers and support groups is the best way to cope with this issue.
Medication can also be an effective part of the treatment for several personality disorders in childhood and adolescence. A doctor's recommendation to use medication often raises many concerns and questions in both the parents and the child. The physician who recommends medication should be experienced in treating psychiatric illnesses in children and adolescents. He or she should fully explain the reasons for medication use, what benefits the medication should provide, as well as the possible negative side-effects or dangers and other treatment alternatives.

Long-standing, deeply ingrained patterns of socially maladaptive behavior that are detrimental to those who display them or to others.
Personality disorders constitute a separate diagnostic category (Axis II) in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Unlike the major mental disorders (Axis I), which are characterized by periods of illness and remission, personality disorders are generally ongoing. Often, they first appear in childhood or adolescence and persist throughout a person's lifetime. Aside from their persistence, the other major characteristic of personality disorders is inflexibility. Persons affected by these disorders have rigid personality traits and coping styles that they are unable to adapt to changing situations and that impair their social and/or occupational functioning. A further difference between personality disorders and the major clinical syndromes listed in Axis I of DSM-IV is that people with personality disorders generally do not perceive that there is anything wrong with their behavior and are not motivated to change it. Although the DSM-IV lists specific descriptions of ten personality disorders, these conditions are often difficult to diagnose. Some characteristics of the various disorders overlap. In other cases, the complexity of human behavior makes it difficult to pinpoint a clear dividing line between pathology and normality in the assessment of personality. There also has been relatively little research done on some of the personality disorders listed in DSM-IV.
The most effectively-diagnosed personality disorder is the antisocial personality. The outstanding traits of this disturbance are an inability to feel love, empathy , or loyalty towards other people and a lack of guilt or remorse for one's actions. Due to the lack of conscience that characterizes it, the condition that is currently known as antisocial personality disorder was labeled moral insanity in the nineteenth century. More recent names associated with this personality type are psychopath and sociopath. Unable to base their actions on anything except their own immediate desires, persons with this disorder demonstrate a pattern of impulsive, irresponsible, thoughtless, and sometimes criminal behavior. They are often intelligent, articulate individuals with an ability to charm and manipulate others; at their most dangerous, they can become violent criminals who are particularly dangerous to society because of their ability to gain the trust of others combined with their lack of conscience or remorse.
There are both biological and psychosocial theories of the origin of antisocial personality disorder. Two of the major components of the antisocial personality—the constant need for thrills and excitement and the lack of anxiety about punishment—may be at least partially explained by research suggesting that antisocial individuals experience chronic underarousal of the central and autonomic nervous systems. In one experiment, anticipation of an electric shock produced a dramatically lower increase of tension in teenagers diagnosed with antisocial personality disorder than in other individuals. In terms of environmental influences, connections have been suggested between the antisocial personality and various patterns of familial interaction, including parental rejection or inconsistency and the retraction of punishment when repentance is claimed.
Some personality disorders resemble chronic but milder versions of the mental disorders listed in Axis I of DSM-IV. In schizotypal personality disorder, for example, the schizophrenic's hallucinations or voices are moderated to the less extreme symptom of an "illusion" that others are present when they are not. Speech patterns, while not incoherent like those of schizophrenia , tend to be vague and digressive. Similarly, avoidant personality disorder has characteristics that resemble those of social phobia , including hypersensitivity to possible rejection and the resulting social withdrawal in spite of a strong need for love and acceptance. The paranoid and schizoid personality disorders are usually manifested primarily in odd or eccentric behavior. The former is characterized mainly by suspiciousness of others, extreme vigilance against anticipated misdeeds, and insistence on personal autonomy. The latter involves emotional coldness and passivity, indifference to the feelings of others, and trouble forming close relationships.
Several personality disorders, including antisocial personality, are associated with extreme and erratic behavior. The most dramatic is the histrionic personality type, which is characterized by persistent attention-getting behavior that includes exaggerated emotional displays (such as tantrums) and overreaction to trivial problems and events. Manipulative suicide attempts may also occur. Narcissistic personality disorder consists primarily of an inflated sense of self-importance coupled with a lack of empathy for others. Individuals with this disorder display an exaggerated sense of their own importance and abilities and tend to fantasize about them. Such persons also have a sense of entitlement, expecting (and taking for granted) special treatment and concessions from others. Paradoxically, individuals with narcissistic personality disorder are generally very insecure and suffer from low self-esteem . Another personality disorder that is characterized by erratic behavior is the borderline personality . Individuals with this disorder are extremely unstable and inconsistent in their feelings about themselves and others and tend toward impulsive and unpredictable behavior.
Several personality disorders are manifested primarily by anxiety and fearfulness. In addition to the avoidant personality, these include the dependent, compulsive, and passive-aggressive personality disorders. Persons with dependent personality disorder are extremely passive and tend to subordinate their own needs to those of others. Due to their lack of self-confidence, they avoid asserting themselves and allow others to take responsibility for their lives. Compulsive personality disorder is characterized by behavioral rigidity, excessive emotional restraint, and overly conscientious compliance with rules. Persons with this disorder are overly cautious and indecisive and tend to procrastinate and to become overly upset by deviations from rules and routines. Passive-aggressive personality disorder involves covert aggression expressed by a refusal to meet the expectations of others in such areas as adequate job performance, which may be sabotaged through procrastination, forgetfulness, and inefficiency. This disorder is also characterized by irritability, volatility, and a tendency to blame others for one's problems.

A further difference between personality disorders and the major clinical syndromes listed in Axis I of DSM-IV-TR (DSM, fourth edition, text revised) is that people with personality disorders may not perceive that there is anything wrong with their behavior and are not motivated to change it. Although the DSM-IV-TR lists specific descriptions of 10 personality disorders, these conditions are often difficult to diagnose. Some characteristics of the various disorders overlap. In other cases, the complexity of human behavior makes it difficult to pinpoint a clear dividing line between pathology and normality in the assessment of personality. In still other cases, persons may have more than one personality disorder, complicating the diagnosis . There also has been relatively little research done on some of the personality disorders listed in DSM-IV-TR.
The 10 personality disorders listed in DSM-IV-TR include:
- Paranoid personality disorder . The individual affected with this disorder believes in general that people will exploit, harm, or deceive him or her, even if there is no evidence to support this belief.
- Schizoid personality disorder . The individual with this disorder seems to lack desire for intimacy or belonging in a social group, and often chooses being alone to being with others. This individual also tends not to show a full range of emotions.
- Schizotypal personality disorder . With this disorder, the affected person is uncomfortable with (and may be unable to sustain) close relationships, and also has odd behaviors and thoughts that would typically be viewed by others as eccentric, erratic, and bizarre.
- Antisocial personality disorder . Individuals with this disorder have no regard for the rights of others. Other, recent names associated with this personality type are psychopath and sociopath. Unable to base their actions on anything except their own immediate desires, persons with this disorder demonstrate a pattern of impulsive, irresponsible, thoughtless, and sometimes criminal behavior.

- Avoidant personality disorder . This disorder has characteristics that resemble those of social phobia , including hypersensitivity to possible rejection and the resulting social withdrawal in spite of a strong need for love and acceptance. Individuals with this disorder are inhibited and feel inadequate in social situations.
- Dependent personality disorder . Persons with dependent personality disorder are extremely passive and tend to subordinate their own needs to those of others. Due to their lack of self-confidence, they avoid asserting themselves and allow others to take responsibility for their lives.
- Obsessive-compulsive personality disorder . This disorder is characterized by a preoccupation with orderliness, perfectionism, and control.
An additional category for personality disorders exists—personality disorder not otherwise specified. This category is reserved for clinicians' use when they encounter a patient with symptoms similar to one of the above disorders, but the exact criteria for a specific disorder are not met.

A personality disorder may be present when a person’s usual way of relating to others, thinking about the world, and reacting to events causes him or her to have problems that interfere with important areas of life, including relationships with other people.

Personality, or personality style, is someone’s usual pattern of thinking, feeling, and behaving. Personality style is made up of a number of personality traits or characteristics. A personality disorder is a problematic personality style that negatively affects most areas of a person’s life. Personality disorders are diagnosed only in adults, but they reflect difficult personality styles that have been present since adolescence or young adulthood. Personality disorders can cause lifelong psychological problems and difficulty in relating to others.
There are 10 different personality disorders that mental health experts may diagnose. Each has its own set of characteristics, and each causes problems of a certain nature. The 10 personality disorders fall into three groups, called clusters, based on similarities in the personality traits of the disorders in each group.
One cluster includes personality disorders that feature unusual points of view or odd or eccentric behavior of various sorts. In this cluster are the following disorders:
- Paranoid: People with paranoid (PAIR-a-noyd) personality disorder distrust other people and may become overly suspicious, believing that other people’s actions are always meant to harm them. Someone with paranoid personality disorder may find it difficult to form friendships, and may be very guarded, argumentative, or cold toward others.
- Schizoid: A person with schizoid (SKIT-zoyd) personality disorder is typically a loner and does not often show emotion. Such people will not make friends easily and do not even care to spend time with their families. A person with this disorder usually chooses a solitary job and activities and has very little, if any, social life.
- Schizotypal: People who have schizotypal (skit-zo-TIE-pal) disorder can be fearful and distrustful of others. They are usually unable to make friends outside their own families. They also can have strange beliefs and superstitions. Often, they will dress oddly or act in a peculiar way that does not seem to “fit in.”
Another cluster includes personality disorders that feature personality styles that are overly dramatic, overly emotional, overly reactive, or unpredictable. In this cluster are the following disorders:
- Antisocial: A person with antisocial personality disorder is typically in trouble with the law and has no respect for the rights of other people. Such people frequently lie and cheat, and they try to take advantage of others for their own profit or enjoyment. They can be very irritable and often get into fights or even attack others. They also may be quite reckless and put themselves or others in danger, and they frequently do not understand or care that they have done something wrong or hurt another person.
- Borderline: A person with borderline personality disorder has difficulty being in relationships. People with this disorder fear that they will be abandoned, and the fear can become so strong that it makes them try to hurt or even kill themselves. Their relationships are often overly intense and they may be very demanding of the time and attention of anyone who is close to them. They may abruptly end relationships and can quickly and drastically change their views about their friends if they think their friends have let them down.
- Histrionic: Histrionic (his-tree-AH-nik) personality disorder makes people want to be the center of attention. To draw attention, people with this disorder can be very dramatic, often making up exaggerated stories about themselves. They flirt to attract people, and they may dress and act in a showy or overly sexy way. They may publicly exaggerate their emotions, perhaps through temper tantrums or fits of crying. People with this disorder can be too trusting of other people and too easily influenced by them.
- Narcissistic: People who have narcissistic (nar-se-SIS-tik) personality disorder are unusually self-concerned. They often exaggerate their talents and accomplishments. They think of themselves as superior to others, and they tend to imagine themselves as very wealthy or powerful or beautiful or intelligent. Because they feel that they are unique, they also need other people to admire them and to treat them as special. But they usually do not care much about the feelings or needs of other people. In fact, they often take advantage of other people to get what they want.
A third cluster includes difficult personalities that feature anxious, fearful, or extremely cautious behavior. In this cluster are the following disorders
- Avoidant: People with avoidant personality disorder fear criticism and disapproval, and for this reason they tend to steer clear of jobs or activities where they must work together with other people. They do not make new friends easily, and they typically are quiet and shy because they fear that other people will embarrass and make fun of them. They often feel out of place in social situations.
- Dependent: A person who has dependent personality disorder has a hard time making even small, everyday decisions, for example, what to wear. People with this disorder often rely on others to take care of them and make all their choices in life. When they are alone, they feel helpless, and they typically look around for someone to care for and support them.
The ancient Greek myth of Narcissus tells the story of a beautiful young man who fell in love with his own reflection. So entranced by his image reflected in the water, he threw himself into the pool and drowned. The term “narcissistic,” or conceited and self-centered, derives from this myth. The Bridgeman Art Library International Ltd.
- Obsessive-Compulsive: People with obsessive-compulsive (obSES-iv-kom-PUL-siv) personality disorder have a deep need for order and control. They pay close attention to rules, lists, and schedules, and they can be very hard on themselves when they do not meet their own high standards of perfection. Some may be incredibly neat and orderly, but others may tend to be pack rats, hoarding money or even saving worthless or unnecessary objects just in case they might need them one day. (Obsessive-compulsive personality disorder is not the same as obsessive-compulsive disorder.)
Personality disorders are difficult to diagnose. This is because many, if not all, of these sorts of traits also are found in normal personalities. A personality disorder is diagnosed only when a personality trait, or a set of traits, is present to such an extreme that it causes an individual to have problems almost every day in almost all interactions.
Several of the personality disorders have traits that overlap, making it difficult to tell one from another. Judging personality styles can be subjective, and different people may have different ideas about each personality style. Even experts may not agree about whether a certain trait in an individual is extreme or simply a variation of normal. Also, when some people have problems as a result of trauma or difficult events in their lives, they may appear to have problems affecting most parts of their lives. Generally, however, these problems are temporary. Researchers continue to work on finding new ways of classifying and diagnosing personality disorders that will be more reliable and accurate.
Since each personality disorder is different, there are separate theories about how each one may develop. There is still much to learn about the factors involved in each of these disorders. Most theories focus on a combination of inborn* traits and early experiences that influence and shape how someone begins to think, feel, and act.
- * inborn
- means present from birth, or inherited.
Because personality disorders can be so deeply ingrained and so longstanding, they are among the most difficult conditions to treat. People with personality disorders often resist change. Although some treatment methods can be effective, change may be slow and gradual. Treatment for personality disorders usually involves long-term talk therapy aimed at helping people understand how their particular pattern causes them trouble and then learning new ways to approach and solve specific problems.
