Defy Dementia Episode 13: Mind the Gap – Women’s Higher Dementia Risk

This episode of Defy Dementia explores why women may face a higher risk of Alzheimer’s disease than men. First, caregiver Angeleta Cox shares the story of her mother, Sonia, a former personal support worker (PSW) who was diagnosed with Alzheimer’s disease in 2017. Then, Dr. Natasha Rajah (Baycrest’s Rotman Research Institute and Toronto Metropolitan University) discusses the latest research on the increased risk of dementia in women, and what women can do to protect their brain health. Don’t miss this episode full of practical brain health tips for you and the women in your life.



Key takeaways

  • Alzheimer’s disease affects more women than men, even considering women’s longer life expectancy.
  • Stress, reproductive history and decreased estrogen during menopause may increase women's dementia risk.
  • Lifestyle factors that decrease dementia risk can differ for men and women. For instance, after menopause, strength training and building muscle mass are particularly important for women to reduce dementia risk.

Key actions to take:

  • Incorporate stress management techniques into your daily routine, such as meditation, yoga, or deep-breathing exercises.
  • Maintain open communication with your healthcare provider about your reproductive health and potential risks.
  • Stay physically active with some cardio and a focus on strength exercises, especially after menopause. To learn more about exercise for brain health, read our exercise resources here.
