Indeed, studies have indicated adults are twice as likely to develop dementia as those with high levels of DHA. And a 1997 study demonstrated that low DHA blood levels are an important risk factor for Alzheimer’s disease.

In children with attention deficit disorder, studies have found that they are not able to convert the precursor ALA omega-3 fatty acids to the longer chain DHA. Yet, their brains are still developing and therefore require optimum DHA amount to learn and focus in school.
The capacity of learning requires the brain to form new neural pathways; if a DHA deficiency is present, the brain will struggle to find what it needs and will compromise by utilizing other type of fatty acids with a wrong structural shape, forming defective and slower new neural pathways
This in turn may possibly lead to difficulty in learning and memorizing, as well as behavior problems. Studies seem to confirm that children suffering from attention deficit disorders and difficulties with assimilating information, such as dyslexia, have a lower level of omega-3s than other fatty acids.
On the other hand, a recent study, conducted in the Netherlands and published in the journal Neuropsychopharmacology, for 16 weeks in 40 boys with and without Attention Deficit Hyperactivity Disorder, has found that an extra daily dose of Omega-3 fatty acids reduced symptoms of inattention, as well as a welter of neuropsychological benefits to Omega-3 supplementation. They received an average of 650 mg per day of Docosahexaenoic Acid (DHA) and 650 mg of Eicosapentaenoic acid (EPA).

Many other authors, studies have shown the dramatic health benefits omega-3 can have on our brain.
For example, Dr. Andrew Stoll, working at McLean’s Hospital, a part of Harvard University Medical School, has done a number of studies using omega-3 fatty acids in depression and bi-polar disorder. He found that “‘omega-3 fatty acids may inhibit neuronal signal transduction pathways in a manner similar to that of lithium …”
