Why are 70% of Alzheimer's patients women?

Is it genetics or age that causes more women to have Alzheimer's? It's more complicated than that. Studies show that of every three patients with Alzheimer's, two are women even after accounting for longevity. Researchers are now only learning the importance of hormones in brain health and it's part of the reason why there's a push behind studying the ways brain health impacts women's health. To find out more about hormones and the role they play during menopause, Nam Kiwanuka speaks with professor M. Natasha Rajah who leads the Brain Health Equity in Aging and Memory lab at Toronto Metropolitan University.
