What this research studies

This large-scale clinical trial is testing if metformin, a common medication, can prevent cognitive decline in individuals who are at risk for Alzheimer's dementia. Participants will receive either metformin or a placebo to see if the medication can slow down memory problems. This work builds on earlier promising results from a smaller study, which suggested that metformin might improve memory in certain individuals. The current trial uses a long-acting form of metformin, which is typically better tolerated, and involves multiple locations to gather more comprehensive data.

Who could benefit from this research

Good fit: Ideal candidates are individuals at risk for Alzheimer's dementia who do not have diabetes and may be overweight or obese.

Not a fit: Patients who already have advanced Alzheimer's dementia or those not at risk for the condition may not receive benefit from this preventative approach.

Why it matters

Potential benefit: If successful, this medication could offer a new way to prevent or delay the onset of Alzheimer's dementia.

How similar studies have performed: A previous small pilot study showed that metformin improved memory recall in participants compared to a placebo.
