Metformin May Cut Dementia Risk, Study Suggests

A recent analysis published in New Scientist indicates that long‑term use of metformin, a common medication for type 2 diabetes, is associated with a reduced risk of developing dementia over subsequent decades. The study found a statistically significant link between metformin therapy and lower dementia incidence, but the authors caution that the evidence is not yet definitive. They note that further research, including randomized controlled trials, is required to confirm causality and to understand the underlying mechanisms. The findings add to a growing body of research exploring the potential neuroprotective effects of diabetes drugs.
