Women are twice as likely as men to be diagnosed with Alzheimer's Disease, and women are far more likely than men to suffer from anxiety, depression, migraines, brain injuries and strokes. The XX Brain reveals groundbreaking research showing that women's brains age distinctly from men's, due mostly to the decline of a key brain-protective hormone: estrogen. Until now, medical research has focused on 'bikini medicine', assuming that women are essentially men with breasts and tubes. The XX Brain reveals how the two powerful X chromosomes that distinguish women from men impact women's brains first and foremost. 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 protect the female brain, including diet and lifestyle strategies proven to work for women. She also examines the controversies about soy and hormonal replacement therapy, the perils of environmental toxins, and gut health. Luckily, it is never too late to take care of yourself. The XX Brain gives women the first plan to address the unique risks and strengths of the female brain for optimal, lifelong brain health.
