A new study reveals that certain common medications may significantly increase the risk of developing dementia in older adults. Researchers analyzed prescription records and health data to identify a link between long-term use of specific drugs—particularly those used to treat anxiety, insomnia, and depression—and cognitive decline. The findings suggest that even standard doses could contribute to memory loss and other neurological symptoms over time, raising concerns about widespread prescribing practices. Experts emphasize the need for further investigation to clarify the risks and guide safer treatment alternatives.
