A study conducted by Matthew Smith et al. and published in The Clinical Journal of Sport Medicine found that, in adolescent athletes, cooling therapy was associated with a significant decrease in post-concussion symptoms.

Findings from a recent study in Nature Mental Health exploring the gut-brain-microbiota axis revealed that those who adhered to a Mediterranean diet experienced reduced PTSD symptoms,

The Journal of Neurotrauma recently published a study comparing conventional rehabilitation to high-intensity training (HIT) in patients with moderate-to-severe traumatic brain injury. Compared to rehabilitation, high-intensity training participants showed better outcomes in the physical tests used to measure locomotive outcomes (6-min walk test and peak treadmill speed). There were also more improvements in aerobic capacity and cognitive functioning after HIT. 

Vision therapy may be valuable for those suffering vision problems after a mild traumatic brain injury (mTBI). Optometrist Maureen Oyaide-Ofenor explains the process of vision therapy in an article published in Optometry Times Journal.

A review article by Stefanie Howell in the Psychiatric Times provides information to identify sleep-wake disturbances after traumatic brain injury (TBI), along with current diagnostic and treatment strategies. Although Howell writes generally about TBI (presumably of all severities), she notes that sleep-wake disturbances may develop after mild TBI (concussion), and several of the studies she references are specifically about mild TBI.
