Official title

Transcranial Photobiomodulation to Improve Cognition in TBI, With Pre-/Post- fMRI Scans: A Pilot, Sham-Controlled Study

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this small, research study is to examine effectiveness of an at-home application of an experimental intervention, on thinking and memory in mild-moderate, closed-head, traumatic brain injury cases. The experimental intervention is light-emitting diode (LED) therapy, which is applied to the scalp and through the nose using a head frame device. Participants are expected to complete two, 5-week series of LED treatments, at home, 3 times a week. There will be a 1-month period between the two series. Each home treatment is 20 minutes. Participants will be trained to use the head frame device, in-office. The head frame device falls within the FDA category General Wellness, low-risk devices, and no medical claims are made. A two-hour paper and pencil testing (4 visits) and a one-hour MRI (3 visits) will be administered before and after each treatment series. Participants may be in the study for about 4 months. This study is supported by Vielight, Inc., Hayward, CA/ Toronto, Canada
