Drexel researchers have developed a device and signal processing algorythm for early detection of epileptic seizures using a single implanted electrode. In animal studies this system has detected seizures between 1 and 4 minutes before the seizure onset. The researcher are preparing to conduct pilot experiments with this device in epileptic patients who are scheduled for surgical treatment.

The device can be used as an early warning tool alerting the individual about the oncoming seizure, or as a part of a closed-loop system detecting the emerging seizure and generating electric stimuli to prevent it. For more information please see the attached executive summary or contact the case manager.

The device can be used as an early warning tool alerting the individual about the oncoming seizure, or as a part of a closed-loop system detecting the emerging seizure and generating electric stimuli to prevent it.

- this device relies on real-time measurements from a single electrode, an not multiple electrodes used in EEG systems

- signal processing is simpler than in EEG-based systems and can be made portable so that the entire system can be worn by the patient without much discomfort

- it can be used as a stand alone seizure warning system or in combination with commercially available brain stimulation electrodes to achieve seizure prevention before seizure affects the patient.
