Primary Outcome Measures:
  • Neuropsychological Test Battery (outcome Measures) [ Time Frame: 4 months in duration ] [ Designated as safety issue: No ]
    The Neuropsychological Test Battery will be at pre-LED Treatment (prior to intervention begins) for Baseline results. Neuropsychological Test Battery will be at repeated at 1 week, 1 month and 2 months following end of LED treatments to look for changes from Baseline results. The primary outcome metric is change in the Test Battery

Study Completion Date: March 2013
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: MedX Health Phototherapy (light and laser therapy)
    The treatment period is 6 weeks (3x per week) for a total of 18 Transcranial LED treatments. Each treatment session is 30 minutes each.
Detailed Description:

This is a four month, outpatient, single center study investigating whether transcranial, high intensity LED applied outside the skull can improve frontal lobe executive function and working memory in participants with chronic, mild Traumatic Brain Injury (TBI), with or without mild posttraumatic stress disorder (PTSD), due to closed head injury.

Participants will sign the Informed Consent Form(ICF) before Neuropsychological Screening test are administered. If the participant's neuropsychological screening test scores meet the Inclusion/Exclusion criteria and the participant meets the other Inclusion/Exclusion criteria, then he/she will be tested again on the tests that are part of the Neuropsychological Outcome Measures, the week before the Transcranial LED treatments, and during the week after the last LED treatment and again at one and two months after the last LED treatment. Treatment with Transcranial LED will be for 6 weeks. Participants will be treated three times per week: Monday, Wednesday and Friday. A total of 18 Transcranial LED treatments will be administered.
