Epidemiology of Personality Disorders in Later Adult Life

There is a small but growing body of literature about the epidemiology of personality disorders among older persons. Notably, there are fewer studies with older persons than with younger persons. Reported rates for the personality disorders are far more inconsistent and controversial than estimates for more widely studied disorders among older persons, such as schizophrenia, dementia, or major depression. Such inconsistencies likely highlight the difficulty clinicians and researchers have in accurately diagnosing personality disorders among older adults (Agronin, 1994). Prevalence estimates for personality disorders are also known to vary widely due to such factors as differing methodologies, sampling techniques, diagnostic measures, and diagnostic criteria. Another important diagnostic issue in prevalence rates is the tendency among older adults to self-report more personality disorder symptoms when compared with the observations of clinicians (Abrams & Horowitz, 1996). Finally, any prevalence rate can be no more precise than the arbitrary cutoff point between personality traits and personality disorder—the typical distinction depends on the degree of impairment required for a diagnosis (Paris, 2005).
