Obsessive‐Compulsive Disorder in the Elderly

Four cases of obsessive‐compulsive disorder arising in late life in association with a presumed organic aetiology are described. Three of the four had brief episodes of OCD earlier in their lives. Neuropsychological assessment demonstrated impairments in verbal fluency and visuo‐spatial tasks. No case exhibited global intellectual impairment. The two patients who complied with appropriate treatment became asymptomatic after 4–6 months.
