Neurofeedback and Mild/Traumatic Brain Injury
According to the Centers for Disease Control (CDC), 1.7 million people sustain a TBI each year in the United States alone.
75% of these TBI’s are considered concussions or mild traumatic brain injury (MTBI). Common symptoms of MTBI consist of fatigue, headaches, visual disturbances, memory loss, emotional disturbances, and sometimes seizures. Current treatments for concussions are limited and mostly consist of resting and some rehabilitation through rehab specialists. Neurofeedback is an option to which some symptom relief may be possible.

Research on Neurofeedback and Mild/Traumatic Brain Injury (TBI)
TBI QEEG abnormalities have been found and researched. Many individuals with TBI have deficits in alpha in the back of the head, increased beta in the back of the head, and connection abnormalities (Thatcher et al., 1991). Other studies show TBI QEEGs varying, but a trend has been found in which there is excess slow (delta, theta, low alpha) and also a deficit in the faster waves (e.g. high alpha, beta, high beta, gamma) with abnormalities in connections of the brain having particular importance (Tabano et al., 1988 ;Trudeau et al., 1998 ;Thatcher, 2000).
