The aims were to (i) report the outcome of mild cognitive disorder (MCD) 3.6 years after initial interview and diagnosis ; (ii) identify predictors of new cases of MCD.
The hypotheses were that (i) persons with MCD are more likely to develop dementia than those without MCD ; (ii) symptoms of anxiety or depression predict MCD caseness at follow-up.
Longitudinal cohort study.
Community of elderly people (age 70-97 years).
612 of 897 elderly subjects (mean 76 years) were reinterviewed.
Of the 36 MCD cases originally identified, 25 were available at follow-up. 24 incident cases of MCD were identified.
ICD-10 dementia, DSM-III-R dementia, ICD-10 mild cognitive disorder diagnoses made by the Canberra Interview for the Elderly, tests of anxiety, depression, neuroticism and cognitive performance.
Of the original 25 MCD cases available at follow-up, two had a diagnosis of MCD, and three had a diagnosis of both ICD-10 and DSM-III-R dementia.
The prevalence of MCD and DSM-III-R dementia at follow-up was no greater for MCD cases diagnosed at initial interview than in normal subjects at initial interview.
There was, however, an increased prevalence of ICD-10 dementia among original MCD cases.
At initial interview and at follow-up MCD cases were more anxious and depressed but had similar cognitive performance to normals.
For incident cases of MCD the only significant predictor was age.
