Transcranial Photobiomodulation Therapy in the Cognitive Rehabilitation of Patients with Cranioencephalic Trauma.

This research evaluated the hemodynamic conditions before and after the transcranial photobiomodulation therapy (PBMT) and investigated neurocognitive changes before and after treatment. Traumatic brain injury (TBI) is the major cause of morbidity and mortality among individuals 21-60 years old and causes ∼500,000 people to be hospitalized in Brazil annually. Some survivors develop an irreversible decrease in neurological function, and the mortality rate is as high as 70% in severe cases.
