Study Summary

Two Chronic Traumatic Brain Injury (TBI) patients who also had depression or post trauamtic stress disorder (PTSD) symptoms  received 633 nm red and 870 nm transcranial light treatment of 13.3 J/cm^2 10 minutes per site, 1x/weeek for 6 years, or 1x/day for 4 months. Researchers treated bilateral left and right forehead (“and multiple other areas”).  At the time of measurement, each had improved executive function, memory and PTSD symptoms.

” Seven years after closed-head TBI from a motor vehicle accident, Patient 1 began transcranial LED treatments. Pre-LED, her ability for sustained attention (computer work) lasted 20 min. After eight weekly LED treatments, her sustained attention time increased to 3 h. The patient performs nightly home treatments (5 years); if she stops treating for more than 2 weeks, she regresses. Patient 2 had a history of closed-head trauma (sports/military, and recent fall), and magnetic resonance imaging showed frontoparietal atrophy. Pre-LED, she was on medical disability for 5 months. After 4 months of nightly LED treatments at home, medical disability discontinued; she returned to working full-time as an executive consultant with an international technology consulting firm. Neuropsychological testing after 9 months of transcranial LED indicated significant improvement (+1, +2SD) in executive function (inhibition, inhibition accuracy) and memory, as well as reduction in post-traumatic stress disorder. If she stops treating for more than 1 week, she regresses. At the time of this report, both patients are continuing treatment. “
