Personality disorders in elderly patients with dysthymic disorder.
The authors evaluated personality disorders in elderly patients with DSM-IV dysthymic disorder (DD) to identify prevalent personality disorders and their clinical correlates. Outpatients (>/=60 years; N=76) with DD were evaluated; most were male (65.8%) and had late age at onset (>50 years: 60.5%). Axis II disorders were present in 31.2% of patients, with obsessive-compulsive personality disorder (OCD; 17.1%) and avoidant personality disorder (11.8%) being the most common. Personality disorders were associated with an earlier age at onset of depressive illness, greater lifetime history of comorbid Axis I disorders, greater severity of depressive symptoms, and lower socioeconomic status. Personality disorders occurred in a minority of elderly patients with DD and mainly comprised the obsessive-compulsive and avoidant subtypes, similar to reports of personality disorders in elderly patients with major depression. In contrast, young adults with DD have been shown consistently to have personality disorders at high frequency. Together with the predominance of late onset and the lack of psychiatric comorbidity, the current findings on personality disorders reinforce our view that DD in elderly patients is typically a different disorder from DD in young adults.
