The Epidemiology of Selected Mental Disorders in Later Life

Dual Diagnosis in Elders Discharged From a Psychiatric Hospital

“…Dementia and severe cognitive impairment are found in 2±14% of older adults, with the incidence increasing with advancing age (Folstein et al, 1985;Evans et al, 1989;Anthony and Aboraya, 1992;McDougall, 1995). The prevalence of anxiety symptoms in this population ranges from 10 to 20% (Sheikh, 1992), and signi®cant depressive symptoms occur in 15±20% of community residents over 65 (NIH, 1991;Steiner and Marcopulos, 1991).…”

Factors associated with depressive symptoms in non-demented community-dwelling elderly

“…The National Epidemiologic Catchment Area Study (ECA) reported that the 1-month prevalence rate for an aective disorder in the United States is 2.5% for adults age 65 and older (Regier et al, 1988). Furthermore, the estimated risk for developing major depression for the ®rst time is 1.25% per year (Anthony and Aboraya, 1992).…”

“…Epidemiologic studies examining the incidence of OCD have found that older adults are less likely, relative to younger adults, to meet diagnostic criteria for OCD. Prevalence rates for individuals over the age of 65 are estimated to be just under 1%, compared to just over 2% for 18-to 44-year-olds and just over 1% for 44-to 65-yearolds, with the data in general suggesting that the risk of developing OCD declines as one ages (Anthony & Aboraya, 1992). However, there is some suggestion that a closer examination of these rates may lead to different conclusions, with women showing a somewhat greater risk of developing OCD in later life (Anthony & Aboraya, 1992).…”

Some studies suggest that OCD is associated with higher IQ, but much of this is based on clinical impression rather than systematic measurement (Rasmussen & Tsuang, 1984).…”
