This research investigates how declining ovarian health influences brain aging and dementia risk. Using genetically engineered mouse models, it identifies inflammation and metabolic stress in the hippocampus associated with low egg quality, suggesting that treatments targeting menopause, hormonal imbalance, or insulin resistance could help protect cognitive health and prevent dementia.

Psychiatric symptoms often precede neurodegenerative diseases, but the biological link remains unclear. This research examines the FMR1 gene using postmortem brain tissue to uncover shared molecular mechanisms, aiming to predict neurodegeneration earlier, improve treatment strategies, and reframe psychiatric symptoms as potential early warning signs.
