Study: DHA Improves Memory and Cognitive Function in Older Adults

Another reason to make sure you have adequate Omega 3 intake. A study was conducted by the Alzheimer’s Association to determine the effects of docosahexaenoic acid on cognition in age-related cognitive decline. The supplementation included 900mg/day of DHA for 24 months.

This methodology used is the absolute bomb when it comes to clincial trials. It was a,

“Randomized, double-blind, placebo-controlled, clinical study was conducted at 19 U.S. clinical sites.”

and what it found was that,

Intention-to-treat analysis demonstrated significantly fewer PAL six pattern errors with DHA versus placebo at 24 weeks (difference score, −1.63 ± 0.76 [−3.1, −0.14, 95% CI], P = .03). DHA supplementation was also associated with improved immediate and delayed Verbal Recognition Memory scores (P < .02), but not working memory or executive function tests. Plasma DHA levels doubled and correlated with improved PAL scores (P < .02) in the DHA group. DHA was well tolerated with no reported treatment-related serious adverse events.

Again, this shows the benefits of omega3 can be found with very small increases (<1g) of daily intake. Another reason to get on the Omega3 bandwagon, and also get grandma and grandpa onto it to!
