DHA increases neurotransmitter activity and improves the number of neurotransmitter receptors, helping the brain to optimize the use of ‘feel-good’ brain chemicals secreted by the brain like serotonin and dopamine. In addition, several studies have evaluated the impact of fatty fish oil on dementia. A study published in Annals of Neurology involving 5,386 elderly participants reported that fish consumption decreased the risk of dementia. Another research published in the British Medical Journal (BMJ) which involved 1,674 elderly residents of southern France concluded that that individuals who ate fish at least once a week had a significantly lower risk of developing dementia over a seven-year period.

However, the researchers said excess amounts of omega-3 fatty acids can alter immune function sometimes in ways that may lead to a dysfunctional immune response to a viral or bacterial infection.
