Omega fatty acids could protect against Alzheimer’s disease in women, new research showed on Wednesday, August 20. 

Scientists from the UK’s King’s College London and Queen Mary University London conducted an analysis of lipids -- fat molecules that perform many essential functions in the body -- in the blood. They found a noticeable loss of unsaturated fats, such as those that contain omega fatty acids, in the blood of women with Alzheimer’s disease compared to healthy women.

They found no significant difference in the same lipid molecule composition in men with Alzheimer’s disease compared to healthy men, which suggests that those lipids have a different role in the disease according to sex. Fats perform important roles in maintaining a healthy brain, so this study could indicate why more women are diagnosed with the disease.
