Mayo Clinic Minute: Brain activities decrease dementia risk

Staying mentally active, even later in life, may decrease your risk of mild cognitive impairment or dementia. That's according to a new Mayo Clinic study published in the online issue of Neurology, the medical journal of the American Academy of Neurology.
Dr. Janina Krell-Roesch, a researcher for Mayo Clinic's Translational Neuroscience and Aging Program, says that taking part in two or more different mentally stimulating activities reduces the risk of mild cognitive impairment in participants 70 and older.
