Credible evidence indicates that omega-3s from fish can help blunt and heal injuries to the brain.
This idea enjoys overwhelming support from lab and animal studies, though human evidence remains limited to case studies.
Cases of dementia, memory loss, suicide, and other brain related problems suffered by football players keep making headlines.
A study sponsored by the National Football League (NFL) found that retired players aged 30 to 49 were 20 times more likely to receive a dementia-related diagnosis, versus their non-NFL peers.
(Because all older people are more likely to have dementia, football players aged 50 or older were "only" five times more likely to receive a dementia-related diagnosis versus their equally aged but non-NFL peers.)
Recent high-profile exposes and tragedies have triggered alarm about the brain-risks of football … in players of all ages.
Seen against the background of positive, albeit inconclusive evidence, the positive results of a preliminary human study warrant urgent action.
The evidence clearly justifies immediate conduct of controlled clinical trials to confirm whether omega-3s from fish can help blunt and/or heal brain injuries … and pinpoint optimally effective doses, formulations, and timing.
Nutrition/activity program may reverse some brain damage
A team led by famed neuroscientist Daniel G. Amen, M.D., reports that a specific nutrition-exercise program improved brain function substantially in 30 former NFL players.

According to him, the findings hold significant implications for prevention and treatment of brain damage due to concussions and other traumas.
Earlier, Dr. Amen – who's an expert in SPECT brain imaging – published three peer-reviewed studies on his work with active and retired NFL players.
The study – titled “Reversing Brain Damage in Former NFL Players” – involved 30 retired players diagnosed with brain damage and cognitive impairment (Amen DG et al. 2011).
This was an “open-label” study that let the participants and researchers know what supplements each participant was taking, and there was no control group.
Hence, it's considered a preliminary study, intended to indicate whether funding of definitive (randomized, double-blind, placebo-controlled) trials is justifiable.
They used SPECT brain imaging and a standard neuro-psych test to measure key brain attributes in the former NFL players … memory, mood, language, attention, cognition (thinking), blood flow, and information processing.
The athletes followed a daily “brain-healthy protocol” designed by Dr. Amen, for two to 12 months (average of six months):
Specifically, the former players took 5.6 grams of fish oil a day, providing 1160mg of omega-3 DHA and 1720mg of omega-3 EPA.
(A daily dose of 5.6 grams is unusually high, but not extreme. It approximates the 4 grams per day that the American Heart Association recommends to heart patients with high blood triglyceride levels.)
Why give brain-damaged former NFL players fish oil?
As the authors wrote, “omega-3 fatty acid supplementation has shown benefits with memory, mood and cognition.” (Amen DG et al. 2011)
Other constituents of the volunteers' supplement regimen included a high-potency multivitamin and a group of brain-boosters shown to:
- Cut cortisol levels (phosphatidylserine)
- Enhance blood flow (ginkgo and vinpocetine)
- Raise acetylcholine levels (acetyl-l-carnitine and huperzine A)
- Raise antioxidant activity (alpha-lipoic acid and n-acetyl-cysteine)
After the end of their trial periods (which averaged six months), each player was tested again.
They showed significant average increases in cognitive scores, blood flow, and self-reported perceptions of mood, memory, and motivation.
By the end of their trial periods, many athletes had achieved 50 percent higher brain-health scores, compared with their scores before starting the Amen team's program.
As Dr. Amen said, “I hope this message finds anyone who played contact sports ... [but] even if you have been bad to your brain … you can often reverse the damage and improve your life.” (GNW 2013)
