Brain tsunamis are seizure-like waves of electrical activity in the brain caused by Traumatic Brain Injuries (TBIs) and strokes. Much like a tidal wave in the ocean, brain tsunamis build power, wash through the brain, and subside, leaving behind a path of destruction. The waves exhibit electrical signal voltage up to ten times that of normal causing changes to chemistry balance, blood flow, and transfer of oxygen through the brain. During the ebb of the wave, they also cause the brain to short-circuit as evidenced by a period of “dead air” in audio recordings. Doctors have been able to track the process of brain tsunamis for several years but only recently have been able to identify the extent of damage.
