Do men’s brains age faster than women’s? What new study says

A major new international study suggests that men’s brains may age faster than women’s challenging long-standing assumptions about brain ageing and Alzheimer’s disease. Researchers analysed brain scans from more than 4,700 healthy adults and found greater brain shrinkage and decline across multiple regions in men. The findings raise new questions about why women are still nearly twice as likely to develop Alzheimer’s, despite slower overall brain ageing. Experts say ageing alone does not cause Alzheimer’s, pointing instead to complex interactions between brain structure, inflammation, genetics and hormones. The study adds a new dimension to the global effort to understand how and why dementia develops.
