One 23-year old traumatic brain injury patient complained of headaches, anxiety, and difficulty concentrating. He home-treated with a Vielight Neuro Duo. At an 8 week measurement he had increased brain volume, improved functional connectivity, increased cerebral perfusion, and neuropsychological improvements.
Five traumatic brain injury patients with cognitive disabilities received transcranial 785 nm infrared laser 5 times per week for 6 weeks. They showed improved awareness and alertness, but two epileptic fits corresponded with treatment earlier that day. The fits also corresponded with concurrent antibiotic treatments.
10 chronic TBI patients received 810 nm and 980 nm infrared laser treatment of 14.8 to 28.3 J/cm^2 2 to 3 times per week for 8 weeks. Treatments were pulsed at 10 Hz. Transcranial treatment spots included 2 sites on the forehead and 3 bilateral, prefrontal and temporal. At measurement they showed improved headaches, sleep disturbances, cognition, mood regulation, anxiety and irritability.
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.
