Kurzfassung:
While Alzheimer’s dementia (AD) has a prevalence as high as 3-32% and is associated
with cognitive dysfunction and the risk of institutionalization, no efficacious and acceptable treatments can modify the course of cognitive decline in AD. Potential benefits of exogenous melatonin for cognition have been divergent
across trials. Objective: The current network meta-analysis (NMA) was conducted under the frequentist model to evaluate the
potential beneficial effects of exogenous melatonin supplementation on overall cognitive function in participants with AD in comparison to other FDA-approved medications (donepezil, galantamine, rivastigmine, memantine,
and Namzaric). Methods: The primary outcome was the changes in the cognitive function [measured by mini-mental state examination
(MMSE)] after treatment in patients with Alzheimer’s dementia. The secondary outcomes were changes
in the quality of life, behavioral disturbance, and acceptability (i.e., drop-out due to any reason and rate of any adverse event reported). Results: The current NMA of 50 randomized placebo-controlled trials (RCTs) revealed the medium-term lowdose
melatonin to be associated with the highest post-treatment MMSE (mean difference = 1.48 in MMSE score, 95% confidence intervals [95% CIs] = 0.51 to 2.46) and quality of life (standardized mean difference = -0.64, 95% CIs = -1.13 to -0.15) among all of the investigated medications in the participants with AD. Finally, all of
the investigated exogenous melatonin supplements were associated with similar acceptability as was the placebo. Conclusion: The current NMA provides evidence for the potential benefits of exogenous melatonin supplementation,
especially medium-term low-dose melatonin, in participants with AD. Conclusions: The current NMA provides evidence for the potential benefits of exogenous melatonin supplementation,
especially medium-term low-dose melatonin, in participants with AD. Trial Registration: The current study complies with the Institutional Review Board of the Tri-Service General
Hospital (TSGHIRB: B-109-29) and had been registered in PROSPERO (CRD42020193088).
