Levels of Omega-3 Could Help Explain Women's Alzheimer's Risk

There's something about the female brain that makes it more susceptible to Alzheimer's disease.

A new study suggests that 'healthy', unsaturated fats, like omega-3, may partly explain that discrepancy.

Compared to men, women typically have higher levels of omega-3 fatty acids, but in the current analysis, women with Alzheimer's showed a surprising dearth in these lipid molecules.

The researchers did not find the same lipid changes in men with Alzheimer's compared to men without Alzheimer's, indicating that these fats may affect the disease differently based on sex.

The findings contribute to an overlooked hypothesis that has been around for decades, implicating fat droplets in Alzheimer's disease.

Historically, these lipids have been overshadowed by tau tangles and amyloid plaq
