Cerebral Oxygen Saturation and Cytochrome Oxidase REDOX State in Children With Epilepsy: A Pilot Study

Brief description of study

The purpose of this pilot study is to describe the relationship of regional cerebral oximetry and cytoximetry, measured using near-infrared spectroscopy, with seizure activity in the periictal period in children with epilepsy.

Detailed Study Description

Pediatric subjects with partial (focal) epilepsy seizure disorders who are being admitted to the epilepsy monitoring unit will be studied using near-infrared spectroscopy for cytochrome c oxidase (CCO) redox state and blood oxygen saturation. Along with routine EEG monitoring, a set of light sensors, called optodes, attached to a net that goes over the head will be put on. These optodes will send out very weak red light signals, which will pass through the scalp and bounce back to detectors on the netting. The changes in the light signals will be used to calculate the changes in the various forms of the enzyme CCO, as well as the amount of oxygen in the blood. We hope to use these measurements to study changes in blood flow and cellular energy usage in the brain during seizures, which might help us to understand epilepsy better in the future and design better treatments.
