Genetics and mathematical modeling point to what goes wrong in epilepsy
Using an innovative technique combining genetic analysis and mathematical modeling with some basic sleuthing, researchers have identified previously undescribed microlesions in brain tissue from epileptic patients. The millimeter-sized abnormalities may explain why areas of the brain that appear normal can produce severe seizures in many children and adults with epilepsy. The findings, by researchers at the University of Illinois at Chicago College of Medicine, Wayne State University and Montana State University, are reported in the journal Brain.
In its first clinical application in pediatric patients, an investigational medication developed and manufactured at UC Davis has been found to effectively treat children with life-threatening and difficult-to-control epileptic seizures without side effects, according to a research report by scientists at UC Davis and Northwestern University.
The investigational formulation of allopregnanolone was manufactured by UC Davis Health System's Good Manufacturing Practice Laboratory. Two children were treated with the allopregnanolone formulation, one at UC Davis Children’s Hospital, the other at the Ann & Robert Lurie Children’s Hospital in Chicago. Both children were weaned from general anesthetics and other seizure treatments and their seizures resolved. In both instances the children are recovering.
Breakthrough in detecting early onset of refractory epilepsy in children will lead to effective treatment using non-pharmacological therapies.
65 MILLION people around the world today suffer from epilepsy, a condition of the brain that may trigger an uncontrollable seizure at any time, often for no known reason. A seizure is a disruption of the electrical communication between neurons, and someone is said to have epilepsy if they experience two or more unprovoked seizures separated by at least 24 hours.
