A new study reveals that certain common medications may significantly increase the risk of developing dementia in older adults, particularly when used long-term. Researchers analyzed health records of thousands of patients, finding a strong correlation between prolonged use of specific drugs—often prescribed for conditions like depression, insomnia, and allergies—and accelerated cognitive decline. The findings suggest that even widely recommended treatments could pose hidden dangers, prompting calls for closer monitoring of at-risk patients. Experts emphasize that individuals should not discontinue medications without consulting their doctors, but the study underscores the need for more rigorous evaluation of these drugs' long-term neurological effects.
