Abstract/OtherAbstract:
OBJECTIVE: to examine the effect of medications with anticholinergic effects on cognitive impairment and deterioration in Alzheimer's dementia (AD).
METHODS: cognitive function was measured at baseline and at 6- and 18-month follow-up using the Mini-Mental State Exam (MMSE), the Severe Impairment Battery (SIB) and the Alzheimer's Disease Assessment Battery, Cognitive subsection (ADAS-COG) in a cohort study of 224 participants with AD. Baseline anticholinergic Burden score (ABS) was measured using the Anticholinergic Burden scale and included all prescribed and over the counter medication.
RESULTS: the sample was 224 patients with Alzheimer's dementia and 71.4% were women. Their mean age was 81.0 years [SD 7.4 (range 55-98)]. The mean number of medications taken was 3.6 (SD 2.4) and the mean anticholinergic load was 1.1 (SD 1.4, range 0-7). The total number of drugs taken and anticholinergic load correlated (rho = 0.44; P < 0.01). There were no differences in MMSE and other cognitive functioning at either 6 or 18 months after adjusting for baseline cognitive function, age, gender and use of cholinesterase inhibitors between those with, and those without high anticholinergenic load.
CONCLUSIONS: medications with anticholinergic effect in patients with AD were not found to effect deterioration in cognition over the subsequent 18 months. Our study did not support a continuing effect of these medications on people with AD who are established on them.
