Omega-3s can improve cognitive abilities in the elderly


Omega-3 fatty acids including EPA, ALA and DHA can improve the cognitive abilities in the elderly individuals, according to a recent study published in Frontiers in Aging Neuroscience.


Omega-3 treated elderly with risk of late-onset Alzheimer’s disease (AD) has performed better in cognitive flexibility tests, compared with their non-treated peers.


According to Dr. Aron Barbey, University of Illinois, research studies have reported a crucial link between the nutritional deficiencies and risk of cognitive impairment and associated degenerative neurological disorders including AD.


Optimal nutrition can support cognitive function, delay aging and related degenerative disorders in the healthy elderly individuals, Dr. Aron said.


The study examined 40 healthy older adults who were aged between 65 and 75 years with a carrier gene variant that contribute to late-stage AD. The participants’ blood fatty acids, cognitive flexibility were tested and compared with the control subjects.


The treated older adults performed better than the non-treated older adults. Higher volume in the anterior cingulate cortex was found in the treated subjects. The relationship between cognitive flexibility and omega-3 fatty acids were proved, the authors wrote in the publication.
