Personality disorders
Definition
Personality disorders are a group of psychiatric conditions in which a person's long-term (chronic) behaviors, emotions, and thoughts are very different from their culture's expectations and cause serious problems with relationships and work.
Causes
The causes of personality disorders are unknown. However, many genetic and environmental factors are thought to play a role.
Mental health professionals categorize these disorders into the following types:
- Antisocial personality disorder
- Avoidant personality disorder
- Borderline personality disorder
- Dependent personality disorder
- Histrionic personality disorder
- Narcissistic personality disorder
- Obsessive-compulsive personality disorder
- Paranoid personality disorder
- Schizoid personality disorder
- Schizotypal personality disorder
Symptoms
Symptoms vary widely depending on the type of personality disorder.
In general, personality disorders involve feelings, thoughts, and behaviors that do not adapt to a wide range of settings.
These patterns usually begin in adolescence and may lead to problems in social and work situations.
The severity of these conditions ranges from mild to severe.
Exams and Tests
Personality disorders are diagnosed based on a psychological evaluation and the history and severity of the symptoms.
Treatment
At first, people with these disorders usually do not seek treatment on their own. They tend to seek help once their behavior has caused severe problems in their relationships or work, or when they are diagnosed with another psychiatric problem, such as a mood or substance abuse disorder.
Although personality disorders take time to treat, there is increasing evidence that certain forms of talk therapy can help many people. In some cases, medications can be a useful addition to therapy.
Outlook (Prognosis)
The outlook varies. Some personality disorders go away during middle age without any treatment, while others only improve slowly throughout life, even with treatment.
Possible Complications
- Problems with relationships
- Problems with career
- Other psychiatric disorders
