Could metabolism play a role in epilepsy?
Date:2/19/2014

February 19Researchers from the Franciscan University of Steubenville, Ohio are exploring a possible link between metabolic defects and seizures. They determined that diet could influence susceptibility to seizures, and they have identified a common diabetes drug that could be useful in treating disorders such as epilepsy.

Dr. Daniel Kuebler, the principal investigator behind the experiment, and his lab made the connection by measuring fruit fly movement with inexpensive web-cams. They have published a peer-reviewed, video demonstration of their method in JoVE, the Journal of Visualized Experiments, to assist others in reproducing and further applying the method.

"This technique has allowed us to identify a number of metabolism-altering drugs that affect seizure susceptibility," said Dr. Kuebler, "It has opened up a new line of research looking at the effect dietary modifications have on seizure susceptibility." As published in the article, his lab team determined that metformin, a drug commonly used to treat type II diabetes, reduces the intensity of seizures.

The drug-screening model system is especially ideal for labs on a tight budget, said Dr. Kuebler. According to the article, "Video tracking systems have been used widely to analyze Drosophila melanogaster movement and detect various abnormalities in locomotive behavior. [But] while these systems can provide a wealth of behavioral information, the cost and complexity of these systems can be prohibitive for many labs." Unlike similar experiments, which study the behavior of these flies in aggregate, Dr. Kuebler and his team's approach studies fly behavior one at a time. This is beneficial in that it can determine subtle differences in behavior and seizure alterations, he said.

While there is no known trigger behind seizures in people with epilepsy, Dr. Kuebler and his lab are using their drug-screening technique to investigate potential metabolic
