Dr. Eric Berg, a health educator and author, warns that prolonged use of certain common medications may increase the risk of developing dementia. In a video shared with his 13 million YouTube followers, Dr. Berg highlights four types of drugs—particularly anticholinergic medications—that could contribute to cognitive decline by blocking acetylcholine, a key neurotransmitter for brain function. These include specific antidepressants, antipsychotics, and urological agents. While effective for treating various conditions, long-term use may raise dementia risk, especially in older adults. Early diagnosis and medical guidance remain crucial, as dementia has no cure.
