New Study: Light Therapy Enhances Brain Connectivity After Injury

Low-level light therapy may enhance brain connectivity in patients with moderate traumatic brain injuries.
According to a study published on May 28 in Radiology, a journal of the Radiological Society of North America (RSNA), low-level light therapy seems to influence healing in the brains of individuals who have experienced significant brain injuries.

Lights of different wavelengths have been studied for years for their wound-healing properties. Researchers at Massachusetts General Hospital (MGH) conducted low-level light therapy on 38 patients who had suffered moderate traumatic brain injury, an injury to the head serious enough to alter cognition and/or be visible on a brain scan. Patients received light therapy within 72 hours of their injuries through a helmet that emits near-infrared light.
