Symptoms
Symptoms vary widely depending on the type of personality disorder.
In general, personality disorders involve feelings, thoughts, and behaviors that don't adapt to a wide range of settings.
These patterns usually begin in the teens 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. The health care provider will consider how long and how severe the person's symptoms are.
Treatment
At first, people with these disorders usually don't seek treatment on their own. This is because they feel the disorder is part of themselves. They tend to seek help once their behavior has caused severe problems in their relationships or work. They may also seek help when they are struggling with another mental health problem, such as a mood or substance use disorder.
Although personality disorders take time to treat, certain forms of talk therapy are helpful. In some cases, medicines are a useful addition.
Outlook (Prognosis)
Outlook varies. Some personality disorders improve greatly during middle age without any treatment. Others only improve slowly even with treatment.
Possible Complications
Complications may include:
- Problems with relationships
- Problems with school or work
- Other mental health disorders
When to Contact a Medical Professional
See your health care provider or mental health professional if you or someone you know has symptoms of a personality disorder.
