I noticed that there is a 2010 Journal of Neurosurgery article by Dr. Julian Bailes and others on the potential benefits of taking fish oil after a TBI (the researchers tested four groups of rodents, three of which were subjected to an "impact acceleration injury." Two of the latter three groups received dosages of omega-3 fatty acids for the 30 days following the injury. The omega-3's apparently had some significant beneficial effects on those groups, for example, in relation to the number of amyloid precursor protein (AAP)-positive axons in the brain). The authors concluded that the omega-3 fatty acids EPA and DHA "are safe, affordable, and readily available worldwide to potentially reduce the burden of traumatic brain injury."

All this makes me wonder whether in the future fish oil will be widely viewed as a significant aspect of post-concussion treatment (and concussion prevention). It also makes me wonder what the appropriate dosage level is - for example, whether it should be higher than the standard 4 capsules or 1500 mg / day (ie, taking into account other risk factors that may prevent people from taking higher doses).
