Omega-3 and memory in older adults


Age-related memory loss is a major health concern of older adults, because it can represent a loss of identity and a loss of independence.

Memory declines with age and up to a certain degree, this is normal, and not a sign of dementia. As we said in a previous post, DHA (docosahexaenoic acid), alone or combined with EPA (eicosapentaenoic acid), helps to improve memory in older adults with mild problems of memory. This shouldn’t surprise us, given that DHA is an omega-3 long chain fatty acid with a very important role in brain structure and function.

According to the outcomes of a meta-analysis recently published (a meta-analysis applies statistical analysis to integrate the data from separate but similar studies of independent researchers, on the same issue), with the objective of determining the effect of DHA intake, alone or combined with EPA (another omega-3 long chain fatty acid), on memory in healthy adults (18 years and older): DHA supplementation, alone or in combination with EPA (but more than 1 g/day DHA plus EPA), is associated with improvement in episodic memory in adults with age-related changes in memory.
