### Implications of Stopping Metformin on Cognitive Health in Older Adults with Diabetes A recent study has found that stopping metformin, a common diabetes medication, may speed up cognitive decline in older adults with diabetes. This is significant because metformin appears to have a protective effect against dementia and other cognitive impairments. Researchers have observed that continued use of metformin lowers the risk of dementia, while stopping it increases this risk. Although more research is needed to confirm these findings, it suggests that maintaining metformin treatment could be beneficial for cognitive health in older adults with diabetes. Additionally, better diabetes control overall, including the use of other medications and lifestyle changes like exercise, can also contribute to better brain health.
