A new study reveals that certain common medications may significantly increase the risk of developing dementia in older adults. Researchers found that prolonged use of specific drugs—particularly those used to treat depression, Parkinson’s disease, and urinary incontinence—was associated with higher likelihoods of cognitive decline. The findings suggest these medications could accelerate brain aging, though experts emphasize the need for further investigation to confirm causality. Patients currently taking these drugs are advised to discuss alternatives with their healthcare providers.
