USC study on fish oil and Alzheimer’s risk

Overview

Researchers at the University of Southern California (USC) conducted a two-year clinical trial involving 365 adults aged 55 to 80 to determine if high-dose omega-3 fish oil supplements could prevent cognitive decline or brain shrinkage in those at risk for Alzheimer’s disease.

The study, published in the journal eBioMedicine, found that while daily supplementation of 2000 mg of docosahexaenoic acid (DHA) successfully increased DHA concentrations in the cerebrospinal fluid by approximately 17 percent, it provided no measurable clinical benefits. Participants receiving the supplements showed no improvements in thinking skills, memory, or cognitive function compared to a placebo group, nor did the supplements slow brain shrinkage.

Dr. Hussein Naji Yassine, director of the USC Center for Personalized Brain Health, noted that although omega-3s are essential for brain cell connections, the results do not support their use as a preventive measure against Alzheimer’s. The findings challenge common marketing claims regarding these products.
