Motherhood could play a role in Alzheimer's risk, new research says
New data suggests women's reproductive history may help doctors predict the risk of Alzheimer's disease. Research by the Alzheimer's Association finds a strong connection to reproductive hormones. Women with three or more children had a 12 percent lower risk of dementia, compared to women with only one child. Dr. Tara Narula joins "CBS This Morning" to discuss the new research.
