BAThe article reports on a major clinical study conducted by a medical team at the University of Southern California (USC), published in the scientific journal eBioMedicine. The research challenges the long-held belief that omega-3 supplements from fish oil significantly improve cognitive function or slow the progression of Alzheimer’s disease. Over two years, participants aged between 55 and 80 with a high genetic risk for Alzheimer’s were given either 2,000 mg of DHA omega-3 daily or a placebo. While the supplement successfully increased brain levels of omega-3s, there was no measurable effect on cognitive performance. Brain scans showed no slowing of hippocampus shrinkage, which is linked to memory loss.
