This meta-analysis pooled seven randomised trials of GLP-1 receptor agonists against placebo or usual care across the Alzheimer's continuum. Mean age of the 4132 participants was 72.1 years, with EVOKE and EVOKE+ contributing 3808\. Cognition did not improve (ADAS-Cog standardised mean difference -0.05, 95% CI -0.12 to 0.02). Disease progression was unchanged (CDR-SB mean difference 0.09, 95% CI -0.10 to 0.28). Adverse events (90.7% vs 84.2%), discontinuation (16.4% vs 7.9%) and weight loss (35.2% vs 7.0%) were all higher. Biomarker findings were inconsistent, certainty of evidence was low, and two of seven trials were at high risk of bias.

*Why it is interesting: GLP-1 drugs have been widely proposed as repurposed dementia treatments on metabolic grounds. The pooled randomised evidence, now dominated by two large trials, shows no cognitive benefit and a tolerability cost.*
