Women's brains appear about three years younger than men's, study finds
New research suggests women's brains do not age as fast as men's. A study in the Proceedings of the National Academy of Sciences analyzed brain scans of more than 200 adults from age 20 to 82. Female brains appeared, on average, about three years younger metabolically than male brains of the same age. Dr. Gayatri Devi, a neurologist at Lenox Hill Hospital in New York who specializes in memory disorders, joins "CBS This Morning" to discuss the findings.
