Research links some drugs to dementia risk

A recent study found some common drugs could increase the risk of dementia or dementia-like symptoms. The study discovered a nearly 50% increase in odds of dementia in people 55 and older who took anticholinergic medications. That type of drug is used to treat a wide range of conditions, including depression, symptoms of Parkinson’s disease, bladder control and insomnia. Dr. Tara Narula joins "CBS This Morning" to discuss the new research and potential risks.

Actor Michael J. Fox is known to millions for the "Back to the Future" films and the TV series "Family Ties" and "Spin City." But for the past two decades it's been his battle with Parkinson's disease, and his search for a cure, that may have generated the most attention.

He has launched an online study to help researchers develop new therapies for the disease. (This story was originally broadcast on October 29, 2017.)
