Annotation	The authors report a comprehensive estimate of the prevalence of 'cognitive impairment, no dementia' (CIND) in an elderly Canadian population. Patients in the community were screened for cognitive impairment by means of the modified mini-mental state examination; a randomly selected sample of this population, and a sample selected from consenting residents in 17 long-term institutions were assessed clinically. Prevalence of CIND was 16.8% - more than all types of dementia combined (8%). Prevalence of all types of cognitive impairment, including dementias, increased with age. Patients with CIND were three times more likely to be living in institutions than were cognitively unimpaired patients. Circumscribed memory loss was the most common category. CIND was related to some degree of functional impairment, and is commonly associated with functional disability and a need for institutional care. This diagnostic category includes a costly group of disorders that merit further study.
