Non-degenerative mild cognitive impairment in elderly people and use of anticholinergic drugs: longitudinal cohort study
Abstract Objective To assess the potential of anticholinergic drugs as a cause of  non-degenerative mild cognitive impairment in elderly people . Design Longitudinal cohort study . Setting 63 r and omly selected general practice s in the Montpellier region of southern France . Participants 372 people aged > 60 years without dementia at recruitment . Main outcome measures Anticholinergic burden from drug use , cognitive examination , and neurological assessment . Results 9.2 % of subjects continuously used anticholinergic drugs during the year before cognitive assessment . Compared with non-users , they had poorer performance on reaction time , attention , delayed non-verbal memory , narrative recall , visuospatial construction , and language tasks but not on tasks of reasoning , immediate and delayed recall of wordlists , and implicit memory . Eighty per cent of the continuous users were classified as having mild cognitive impairment compared with 35 % of non-users , and anticholinergic drug use was a strong predictor of mild cognitive impairment ( odds ratio 5.12 , P = 0.001 ) . No difference was found between users and non-users in risk of developing dementia at follow-up after eight years . Conclusions Elderly people taking anticholinergic drugs  had significant deficits in cognitive functioning and were highly likely to be classified as mildly cognitively impaired , although not at increased risk for dementia . Doctors should assess current use of anticholinergic drugs in elderly people with mild cognitive impairment before considering administration of acetylcholinesterase inhibitors
