From database inception to May 25, 2019

Randomized controlled trials

20, with 5 included in meta-analysis

<div>Findings demonstrated a positive effect (mean difference [MD] = 1.10) of cognitive stimulation therapy (CST) plus pharmacotherapy on cognitive function in individuals with Alzheimer's disease. A greater reduction in behaviors associated with dementia was additionally noted with CST plus pharmacotherapy compared to pharmacotherapy alone (MD = &minus;2.14). Length of duration had a positive impact on outcome, with longer-term CST resulting in improved cognitive function (MD = 2.54) when compared to short-term (MD = 1.05) and maintenance CST (MD = 0.83).</div> <div>&nbsp;</div> <div>Limitations for the review included a lack of study of the effect of CST in isolation (i.e. without pharmacotherapy), the lack of in-depth evaluation of cognition versus use of a screening tool, limited methodological rigor within studies included, and a limited number of studies investing the effects of CST. Further research is warranted.</div>
