For people with mild traumatic brain injury (TBI), daily morning exposure to blue-light therapy may reduce depression and other post-concussion symptoms, according to a small study.

US researchers enrolled 35 young adults (mean age 26), diagnosed with mild TBI during the past 18 months, in a randomised, double-blind study.
