Anti-aging Drug Shows Promise in Improving Brain Blood Flow for Alzheimer's Risk Group

A new study suggests an anti-aging drug may improve brain blood flow in individuals at higher risk for Alzheimer's disease, particularly those carrying the APOE4 gene variant.

Researchers investigated the effects of rapamycin, a drug typically used to prevent organ transplant rejection, on healthy middle-aged adults (45-65) who carry the APOE4 gene. This gene variant is linked to an increased risk of Alzheimer's disease and is often associated with reduced brain blood flow before cognitive symptoms appear.

The study found that participants with the APOE4 gene who took a low dose of rapamycin daily for four weeks experienced improved blood flow in their brains. This improvement was not observed in participants without the gene variant.

Notably, female participants with the APOE4 gene showed the most significant improvement in brain blood flow. This finding is particularly relevant as women constitute a majority of Alzheimer's patients.

The research, led by Ai-Ling Lin, aims to identify preventative strategies for Alzheimer's by targeting brain aging in at-risk populations. The study was published in the Journal of Cerebral Blood Flow & Metabolism.
