The instant New York Times bestseller! "In The XX Brain, Lisa meticulously guides us in the ways we can both nourish and protect ourselves, body and mind, to ensure our brains remain resilient throughout our lives." —from the foreword by Maria Shriver The first book to address cognitive enhancement and Alzheimer's prevention specifically in women—and to frame brain health as an essential component of Women's Health. In this revolutionary book, Dr. Lisa Mosconi, director of the Women's Brain Initiative at Weill Cornell Medical College, provides women with the first plan to address the unique risks of the female brain. Until now, medical research has focused on "bikini medicine," assuming that women are essentially men with breasts and tubes. Yet women are far more likely than men to suffer from anxiety, depression, migraines, brain injuries, and strokes. They are also twice as likely to end their lives suffering from Alzheimer's disease, even when their longer lifespans are taken into account. But in the past, the female brain has received astonishingly little attention and was rarely studied by medical researchers— resulting in a wealth of misinformation about women's health. The XX Brain confronts this crisis by revealing how the two powerful X chromosomes that distinguish women from men impact the brain first and foremost and by focusing on a key brain-protective hormone: estrogen. Taking on all aspects of women's health, including brain fog, memory lapses, depression, stress, insomnia, hormonal imbalances, and the increased risk of dementia, Dr. Mosconi introduces cutting-edge, evidence-based approaches to protecting the female brain, including a specific diet proven to work for women, strategies to reduce stress, and useful tips for restorative sleep. She also examines the controversy about soy and hormonal replacement therapy, takes on the perils of environmental toxins, and examines the role of our microbiome. Perhaps best of all, she makes clear that it is never too late to take care of yourself. The XX Brain is a rallying cry for women to have full access to information regarding what is going on in their brains and bodies as well as a roadmap for the path to optimal, lifelong brain health.
