Cold Meds, Dementia Can Be A Dangerous Mix
Studies show long-term use of over-the-counter cold medicines that contain antihistamines can increase the risk of developing dementia. These medications can also be dangerous for people who already have dementia. That's because antihistamines interfere with a chemical in the brain called acetylcholine. That chemical acts as a neurotransmitter that serves a vital role in memory. (Goldberg, 1/30)
