Abstract

Abstract Background To assess the effectiveness, safety, and tolerability of anti-Alzheimer agents (memantine, galantamine, rivastigmine, and donepezil) in controlling ADHD symptoms in children, adolescents, and adults. Methods Following the PRISMA guideline, clinical trials assessing the potency of anti-Alzheimer medications in managing ADHD symptoms were imported from PubMed, Web of Science, and Scopus (until February 2023). Screening stages were conducted by two independent researchers. Two independent researchers also extracted data from clinical trials reporting the outcomes as the reduction in scores of ADHD questionnaires. The risk of bias within the included studies was assessed using the Cochrane Collaboration tool, while the certainty of outcomes was evaluated based on the GRADE criteria. Results Of the initial 1597 studies, 11 studies were included. No studies were available for rivastigmine, and only a single study was conducted for galantamine. The results of the other two medications had a slight inconsistency. While both memantine and donepezil were reported to be effective in several studies, they were reported to be ineffective in some other studies. Side effects were mostly reduced appetite and headache. The tolerability of memantine, donepezil, and galantamine was all convincing. Conclusions While galantamine did not demonstrate a promising efficacy in ADHD, memantine and donepezil showed effectiveness. However, future studies are needed to confirm their efficacy in ADHD since there was some inconsistency.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
