In patients with a personality disorder, risk for death is usually related to conditions or behaviors resulting from the disorder. Patients with personality disorders are at higher risk than the general population for many (axis I) psychiatric disorders. Mood disorders are a particular risk across all personality disorder diagnoses. Moods of depression and anxiety are frequently associated with suicidal behaviors. Some comorbidities are more specific to particular personality disorders and clusters. For example, patients with BPD may have major depression.

Personality disorders are lifelong conditions, although attributes of cluster A and B disorders tend to become less severe and intense in middle age and late life. Patients with a cluster B personality disorder are particularly susceptible to substance abuse, impulse control, and suicidal behavior, which may shorten their lives. Cluster C characteristics tend to become exaggerated in later life.

According to the American Psychiatric Association, cluster A disorders include the following:

  • Paranoid personality disorder

  • Schizoid personality disorder

  • Schizotypal personality disorder

Cluster B disorders and their morbidities include the following:

  • Antisocial personality disorder

  • Borderline personality disorder

  • Histrionic personality disorder

  • Narcissistic personality disorder

Cluster C disorders and their morbidities include the following:

  • Avoidant personality disorder

  • Dependent personality disorder

  • Obsessive-compulsive personality disorder
