Abstract
Apathy is highly prevalent in Alzheimer's disease (AD), but whether pharmacotherapy is effective in managing apathy is unclear. To assess the efficacy of pharmacotherapy for apathy in AD we searched for randomized controlled trials (RCT) and aggregate data reporting on apathy in several search engines, reference lists of articles, and reviews. Demographic characteristics and relevant data were extracted to assess apathy. Fifteen RCTs' were examined, and 11 were used in aggregate meta-analytic statistics. Drugs included were cholinesterase inhibitors, memantine, and psycho-stimulants. We found no significant treatment effect in favour of any of the drugs, and the effect-size estimates under a random effect model were heterogeneous. Most RCTs had a high attrition rate and used the NPI apathy subscale to measure apathy. The lack of an effect could be explained by methodological limitations, publication bias, and heterogeneity.
