How effective are cholinesterase inhibitors and memantine for dementia?
Cognitive and global functioning, behaviour, and quality of life measures such as activities of daily living and caregiver burden. Secondary outcomes: mortality, rate of institutionalisation, and adverse events.
Design: Systematic review with meta-analysis
Data sources: MEDLINE, Pre-MEDLINE, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials, Allied and Complementary Medicine Database, CINAHL and AgeLine were searched from January 1986 to November 2006 for English language articles. Reference lists of identified studies were hand searched.
Study selection and analysis:
RCTs of cholinesterase inhibitors or memantine in people with major dementia (including Alzheimers, vascular and Parkinsons dementia) compared to placebo or another drug. Measures of cognition were the Alzheimers Disease Assessment Scale (ADAS; cognitive and non-cognitive subscales), Severe Impairment Battery (SIB), and Mini-Mental State Examination. The validated measure of global functioning was the clinician-based impression of change with caregiver input (CIBIC-plus). Heterogeneity was investigated
