BACKGROUND: Given the growing global public health burden of Alzheimer's disease, this study used the Bayesian network meta-analysis to assess the effects of pharmacological and non-pharmacological interventions on cognitive function in the population with Alzheimer's disease.
METHODS: Two investigators screened the literature from English databases (PubMed, MEDLINE, Embase, Cochrane CENTRAL, and Web of Science) and three major Chinese bibliographical databases (China National Knowledge Infrastructure Database, Wanfang Database, and VIP Database). We assessed the risk of bias and publication bias of the selected literature. Subsequently, a Bayesian network meta-analysis and meta-regression were conducted to further investigate the comparative efficacy of different interventions on cognitive outcomes.
RESULTS: A total of 4788 cases were initially identified. Photobiomodulation [SMD=0.66, 95%CrI (0.29, 1.02)], enriching environment [SMD=0.69, 95%CrI (0.08, 1.31)], pharmacological therapy [SMD=0.36, 95%CrI (0.17, 0.55)], cognitive stimulation therapy [SMD=0.32, 95%CrI (0.11, 0.55)] and exercise therapy [SMD=0.28, 95%CrI (0.06, 0.51)] showed considerable enhancements in cognitive function among individuals with Alzheimer's disease. Photobiomodulation and enriching environment stood out, with their effects more potent than those of other therapies, as indicated by the surface under the cumulative ranking curve - photobiomodulation clocked in at 87.3%, while enriching environment scored 83.8%, versus pharmacological therapy's 54.7%.
CONCLUSIONS: Among the interventions evaluated, photobiomodulation and enriching environment were associated with better improvements in cognitive function than pharmacological therapy. Exercise therapy and cognitive stimulation therapy also demonstrated beneficial effects. Music therapy showed no statistical difference from the control group. In addition, the research developed an innovative approach to contrast pharmacological and non-pharmacological treatments for Alzheimer's disease.
