Study finds female mice with only maternal X chromosome age faster mentally, raising Alzheimer's risk.
A new study by UC San Francisco researchers reveals that female mice expressing only a maternal X chromosome show faster memory and cognitive decline compared to those with both maternal and paternal X chromosomes.
Published in Nature, the research suggests this genetic pattern could explain varying rates of brain aging among women and potentially raise the risk for diseases like Alzheimer's.
The findings highlight the importance of the maternal X chromosome in brain function and aging.
