Personality disorders occur in 10 to 20 percent of the general population, and they can last for decades. A personality disorder is also a predisposing factor for other psychiatric disorders, such as substance abuse, suicide, affective disorders, impulse-control disorders, eating disorders, and anxiety disorders. Individuals with personality disorders are far more likely to refuse psychiatric help and to deny their problems than persons with other mental health conditions. That’s because they are not concerned about their maladaptive behavior.
