Higher omega-3 levels linked to better cognitive function following depression in older adults

Associations between omega-3 PUFA concentrations and cognitive function after recovery from late-life depression
– Source: American Journal of Clinical Nutrition, Feb 2012

By CC Chiu, et al.

[Note: Though omega-3 PUFAs can be derived from animal sources, especially fish and krill oils, the omega-3 food chain originates in plants – e.g., seaweed & algae eaten by krill and fish. The omega-3s in fish oil and krill oil are called eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The omega-3 found in plant sources such as flaxseed is called alpha-linolenic acid (ALA). The red blood cells of the subjects in this study were tested for all of these.]

Abstract:
Background: Lower concentrations of n-3 PUFAs [omega-3 polyunsaturated fatty acids]:

• Have been reported to be associated with cognitive impairment and dementia,

• But also with depression - itself a potential risk factor for cognitive decline.

Objective: The aims of this study were to investigate associations between n-3 PUFA concentrations in erythrocyte [red blood cell] membrane or plasma [liquid in which blood cells are suspended] and cognitive function in an at-risk sample of older people with previous major depression, and to explore specificity with respect to cognitive domains.

Design:
• A cross-sectional sample of 132 eligible participants who had recovered from major depression (mean +/- SD age: 67.8 plus/minus 6.6 years) were enrolled from outpatient psychiatric services.

• A series of cognitive tests and a structured questionnaire were administered.

• Fasting blood samples were collected for n-3 PUFA measurements.

Results: Higher EPA and total n-3 PUFA concentrations and a lower ratio of arachidonic acid-to-EPA in erythrocyte membranes were associated with a higher cognitive composite score: independent of age and sex, but no longer significant after adjustment for education. No associations were found with plasma concentrations of any fatty acid. [Arachidonic acid is a type of omega-6 PUFA most plentiful in red meats that is essential for growth of skeletal muscle but considered harmful when in a higher ratio vs. omega-3s.]

Considering individual cognitive tests the strongest and most consistent correlations were found between immediate recall and concentrations of total n-3 PUFAs and alpha-linolenic acid (ALA) in erythrocytes, which were observed only in participants with recurrent depression.

Conclusions:
• Total erythrocyte n-3 PUFA concentrations are positively associated with cognitive function, particularly immediate recall, in older people with previous depression. [Higher levels, better cognitive function & immediate recall, and vice-versa.]

• Lower concentrations of n-3 PUFAs or ALA in erythrocyte membranes may be good predictors for cognitive impairment in older people with previous recurrent depression.
