Dive into the lives of five veterans and learn who they were before they served our country, how they suffered their own unique TBI that halted their service while in combat, and their difficult transition back home to their families and civilian life. They will each be given a SPECT brain scan at the start and end of a 12-week therapy of low-level light therapy to see the direct results of this new FDA cleared device that will give new light and hope. Each veteran carries a different, impactful story of sacrifice, struggles, missed diagnosis, suicidal thoughts, tendencies, and the battle back for the life they once had–but now there is light at the end of the tunnel.
