Fish Oil Helps Alzheimer's Patients: Study

Fish oil can reverse some of the ravages of Alzheimer’s disease, new research suggests.

In a study published in the journal Frontiers in Aging Neuroscience, University of Illinois researchers found older adults at risk of late-onset Alzheimer's disease who consumed more omega-3 fatty acids did better than their peers on tests of mental-health function.

Specifically, they found the brain-boosting acids helped to promote “cognitive flexibility” — the ability to efficiently switch between tasks — and had larger regions of the brain associate with such skills, which typically decline in dementia patients.

The results suggest consuming EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) — two omega-3 fatty acids found in fish and fish oil — can help improve the lives of Alzheimer’s patients.

"Recent research suggests that there is a critical link between nutritional deficiencies and the incidence of both cognitive impairment and degenerative neurological disorders, such as Alzheimer's disease," said lead researcher Aron Barbey, a University of Illinois professor of neuroscience, psychology, speech and hearing.

"Our findings add to the evidence that optimal nutrition helps preserve cognitive function, slow the progression of aging and reduce the incidence of debilitating diseases in healthy aging populations."

The new study involved 40 adults between the ages of 65 and 75 who are carriers of a gene variant (APOE e4) that is known to contribute to the risk of developing late-onset Alzheimer's disease.
The researchers tested participants' cognitive flexibility, measured levels of the fatty acids in their blood, and imaged their brains using MRI.

The results showed a clear association between higher omega-3 fatty acids and better cognitive flexibility.
