About the Study
A study published in the Journal of Alzheimer’s Disease entitled Impact of Omega-3 Fatty Acid Supplementation on Memory Functions in Healthy Older Adults was recently conducted to further analyze the potential benefits of omega-3s for brain function, specifically learning and memory function. In this double-blind placebo-controlled study, 44 cognitively healthy men and women aged 50–75 years received either a long chain polyunsaturated omega-3 supplement (2,200 mg/day of omega-3s) or a placebo for 26 weeks. Before the study, memory tasks were tested, and reevaluated when the study concluded. Auditory Verbal Learning Tests (AVLT), dietary habits, omega-3-index (omega-3 blood levels), and other blood-derived factors were also assessed.
What did the study find?
The researchers found that the group that took the omega-3 supplements had a greater improvement in their memory, specifically with the recall of object location, versus the group that took the placebo. Additionally, the group that took the omega-3 supplements had a significantly greater omega-3 index than that of the placebo group.
What does this mean to me?
Alzheimer’s is a growing problem in Canada, with 1.1 million Canadians expected to have the disease in the next 25 years. There is currently no treatment for Alzheimer’s disease and the exact cause still remains unknown.
This study adds to the growing body of scientific evidence that omega-3 fatty acids can have a positive effect on memory and brain function. It further supports longtime research that shows prevention of cognitive decline through a diet high in omega-3s and through omega-3 supplementation is key in helping to reduce the risk the Alzheimer’s disease and plays an important role in maintaining optimal brain health.
