ABSTRACT
There has been no systematic study of the clinical features of obsessive-compulsive disorder (OCD) in elderly patients. This study describes the symptoms and characteristics of OCD among 32 outpatients age 60 or older and 601 younger patients meeting DSM-III-R criteria and given the Yale-Brown Obsessive-Compulsive Scale (YBOCS), NIMH scale, and a 41-item symptom questionnaire. Elderly patients had a later age at onset compared with younger patients. No differences were found in severity of symptoms on the YBOCS. Elderly patients had fewer concerns about symmetry, need to know, and counting rituals. Handwashing and fear of having sinned were more common. There were few differences in clinical features of OCD among the elderly patients compared with younger OCD patients.
