University of Minnesota engineering researchers discover new non-invasive method for diagnosing epilepsy
Date:8/24/2012

A team of University of Minnesota biomedical engineers and researchers from Mayo Clinic published a groundbreaking study today that outlines how a new type of non-invasive brain scan taken immediately after a seizure gives additional insight into possible causes and treatments for epilepsy patients. The new findings could specifically benefit millions of people who are unable to control their epilepsy with medication.

The research was published online today in BRAIN, a leading international journal of neurology.

The study's findings include:

  • Important data about brain function can be gathered through non-invasive methods, not only during a seizure, but immediately after a seizure.
  • The frontal lobe of the brain is most involved in severe seizures.
  • Seizures in the temporal lobe are most common among adults. The new technique used in the study will help determine the side of the brain where the seizures originate.

"This is the first-ever study where new non-invasive methods were used to study patients after a seizure instead of during a seizure," said Bin He, a biomedical engineering professor in the University of Minnesota's College of Science and Engineering and senior author of the study. "It's really a paradigm shift for research in epilepsy."

Epilepsy affects nearly 3 million Americans and 50 million people worldwide. While medications and other treatments help many people of all ages who live with epilepsy, about 1 million people in the U.S. and 17 million people worldwide continue to have seizures that can severely limit their lives.

The biggest challenge for medical researchers is to locate the part of the brain responsible for the seizures to determine possible treatments. In the past, most research has focused on studying patients while they were having a seizure, or what is technically known as the "ictal" phase of a seizure. Some of these studies involved invasiv
