Decoding the Female Brain: Investigating Cerebral White Matter Changes throughout the Menopausal Transition, using diffusion MRI
Women make up half of the global population and spend nearly one third of their lives in perior postmenopause. This period is marked by major hormonal changes that not only impact the reproductive system, the brain is greatly affected too. Despite this, the female brain remains understudied, and relatively little is known about how menopause influences brain health. Previous research has shown that during the menopause transition, the brain becomes less efficient at using glucose, its main energy source under normal circumstances. These metabolic changes may alter brain structure and function, potentially contributing to common menopause symptoms, such as hot flushes, mood changes or memory problems. They may also partly explain why women have a higher risk of developing Alzheimer’s disease later in life. This thesis contributes to a better understanding of the menopausal brain by using advanced medical imaging techniques to investigate changes in the brain’s white matter. In the long term, this research may contribute to improved public health and women’s healthcare, by advancing our understanding of menopause-related brain changes and female brain aging. Findings may positively impact healthcare professionals, public health organizations, researchers in neuroscience and women’s health, pharmaceutical and biotech companies. Most importantly, this research may eventually improve patients’ quality of life by supporting better management of menopausal symptoms and informing earlier detection, prevention, and treatment of neurodegenerative diseases such as Alzheimer’s disease.
