Women's brains age differently than men's, with changes triggered by declining estrogen levels during perimenopause leading to higher risks of Alzheimer's disease, anxiety, depression, migraines, brain tumors, and strokes.
Recognizing and studying the subtle functional differences between female and male brains, which are related to hormones, genetics, and behavior, is crucial for providing effective healthcare for both genders.
Pregnancy leads to significant changes in the female brain, with hormonal surges causing adaptations in brain structure and function to support maternal attachment and neural growth.
The menopausal transition, or perimenopause, affects women's brain health through hormonal changes, leading to symptoms such as brain fog, depression, anxiety, hot flashes, and sleep disturbances.

Women's Brain Health and Underresearched Areas of Medicine
Women's brain health remains one of the most under-researched, under-diagnosed, and under-treated fields of medicine. This lack of attention is a consequence of the reductive understanding of what a woman is. However, women's brains age differently than men's, with key turning points that accelerate or slow down the aging process. For instance, during midlife, women may experience changes triggered by declining estrogen levels during perimenopause. These changes can lead to higher risks of Alzheimer's disease, anxiety, depression, migraines, brain tumors, and strokes. It is important to address the gender bias in research and medical care to provide better understanding and treatment for women's brain health.
Functional Differences in Female and Male Brains
There are subtle functional differences between female and male brains, rather than structural differences. For example, women tend to have better verbal memory and men have better visuospatial abilities. These differences are related to the interaction of hormones, genetics, and behavior. Furthermore, the brain aging process is different for women, with distinct neuroendocrine transitions that impact brain health. Recognizing and studying these differences is crucial for providing effective healthcare for both men and women.
Impact of Pregnancy on the Female Brain
Pregnancy leads to significant changes in the female brain. Hormonal surges during pregnancy cause the brain to undergo morphological and functional adaptations to support maternal attachment and the growth of new neural connections. These changes in brain structure and function affect memory, energy levels, and thinking processes. The brain's plasticity and response to estrogen play a crucial role in these adaptations. However, after giving birth, the brain goes through a period of shrinkage and regrowth. These changes help prioritize infant care and support the development of mother-child attachment.
The Menopausal Transition and its Impact on Brain Health
The menopausal transition, also known as perimenopause, is a phase of hormonal changes that affects women before reaching menopause. As estrogen levels decline, women may experience various neurological and physical symptoms such as brain fog, depression, anxiety, hot flashes, and sleep disturbances. These symptoms can be disruptive and worrisome for women going through this transition. It is important to raise awareness and provide support for women during this phase.
The Importance of Addressing Cognitive Health in Women and Reducing Risk Factors
The podcast episode discusses the significance of focusing on cognitive health in women and reducing the risk of dementia and other conditions. It emphasizes the need to address not only dementia but also anxiety, depression, and other related factors. The episode highlights that dementia is not solely a disease of old age, emphasizing the importance of taking preemptive and preventive action from a younger age.
Hormones, HRT, and Brain Health
The podcast explores the topic of hormones, specifically hormone replacement therapy (HRT), in relation to brain health. It discusses the various perspectives on the use of hormones to support brain health and highlights the importance of understanding the timing and effectiveness of hormone therapies. The episode emphasizes the need for further research and a better understanding of the interplay between hormones, brain health, and the aging process.
Stress, Exercise, and Brain Health
The podcast delves into the impact of stress and exercise on brain health. It highlights the negative effects of chronic stress on hormones and emphasizes the importance of stress management for overall brain health. Furthermore, the episode highlights the significant benefits of exercise, explaining that exercise is essential for both men and women but may have even stronger benefits for women's brain health. It suggests moderate intensity exercise as a key strategy for maintaining brain health throughout life.
Women's brain health remains one of the most under researched, under diagnosed and under undertreated fields of medicine. Women are twice as likely as men to develop Alzheimer’s and twice as likely to become anxious or depressed. They are four times more likely to suffer with headaches and migraines and they are more prone to brain tumours and strokes than men. Today’s guest says this is a clear indication of functional differences between female and male brains. And she’s made it her life’s work to learn more about it.
Neuroscientist Dr Lisa Mosconi is director of the Women’s Brain Initiative and works at the Alzheimer’s Prevention Clinic at Weill Cornell Medical College, US, where she studies how genetics, lifestyle and nutrition shape brain health, particularly in women.
Lisa describes her frustration at constantly being told by peers that the reason Alzheimer’s was more prevalent in women was simply because they live longer, and it’s a disease of ageing. We discuss her ground-breaking research that has exposed this bias, finding dementia brain changes can actually begin in midlife, triggered by declining oestrogen during perimenopause. Worrying as that might sound, this discovery will enable women to take control of their risk at a much earlier age. Lisa goes on to share plenty of practical, evidence-based advice to help you do that.
I was really moved hearing Lisa talk about the beautiful changes that happen in the female brain during pregnancy and post-partum. It’s a new take on the idea of ‘Mummy brain’ and will be validating for all mothers out there to hear. She also gives a clear and candid explanation of how perimenopause alters brain function. So many of my patients in their 40s and 50s are scared by changes like forgetfulness, brain fog and anxiety. If that’s you or someone you know, Lisa’s insights and advice will be really empowering.
I’m a passionate advocate for women’s health equality. Yet chatting with Lisa made me realise how much more work we all have to do to get topics like these out there and understood. This conversation is relevant to all of us, women and men alike. I hope it gets you thinking and talking more.
