It’s reported that Dr. Margaret Naeser from Boston University School of Medicine and colleagues from Massachusetts General Hospital and Harvard-MIT Division of Health Sciences and Technology, has developed LED therapy to treat patients with traumatic brain injury (TBI).

The phototherapy technique delivers red and near-infrared light energy to improve cellular metabolism which offers physiological benefits. With daily use of LEDs on the scalp and forehead, improvement was noticed in the cognitive functioning and it also showed reduction in the post-traumatic stress disorder among patients with brain injury.

Scientists studied two individuals with TBI. It’s proved that patients showed improved focus, attention, memory and inhibition after the treatment. What’s more, one of the participants even returned back to work.

As a result, it is a significant research. It’s believed that the increasing number of non-fatal traumatic wounds and the rise in the prevalence of dementia and other degenerative disorders among the older population will benefit from this LED therapy.
