Brain waves may predict and potentially prevent epilepsy

There’s an upside to have suffered a brain injury – seriously – and that there’s a biomarker that’s present in the brain visible through an EEG scan recording the theta brain waves.

The findings, discovered by Ben-Gurion University of the Negev (BGU) researchers, published in The Journal of Neuroscience, demonstrate how using EEGs to identify changes in brain wave patterns over time can predict which post-injury patients will develop epilepsy. A neurological disorder that disturbs nerve cell activity in the brain, epilepsy causes seizures during which people experience uncontrolled shaking and movement or loss of consciousness.

“Post-injury epilepsy (PIE) is a devastating, unpreventable consequence of traumatic brain injury (TBI) and stroke, which develops in 10 to 40 percent of survivors months, or even years later,” says BGU Professor Alon Friedman, a researcher in the Brain Imaging Research Center and the Zlotowski Center for Neuroscience.
