Effective treatments for traumatic brain injury (TBI) are lacking. Our published data show multi-Watt Near-infrared light therapy (NILT) at 10-13 W yields clinical recovery. We propose a double-blind controlled study of this 'neuro-laser' with 30 TBI patients examined with a neuropsychological battery and baseline neuroimaging. Subjects receive active laser treatment vs sham laser. All subjects will be reassessed by neuropsychological testing and brain imaging at one month after treatment.
