Treatment with glucagon-like peptide-1 receptor agonists (GLP-1 RAs) is associated with a reduced incidence of dementia in patients with type 2 diabetes.

If you have Type 2 Diabetes, discuss GLP-1 receptor agonists (like liraglutide or semaglutide) with your doctor. This paper suggests these medications may lower your risk of developing dementia compared to other diabetes treatments. This is particularly relevant if you are at high cardiovascular risk.

GoodSupportsHIGH confidence
We found that treatment with GLP-1 RAs was associated with a reduced incidence of dementia in patients with type 2 diabetes in three pooled RCTs and in a nationwide cohort.

Why this rating

Combines high-quality RCT data with a large, real-world nationwide registry, though dementia was not a prespecified endpoint in RCTs.
