Closed-loop implant to target seizure-related high-frequency brain waves in drug-resistant epilepsy

Acute Modulation of Stereotyped High Frequency Oscillations with a Closed-Loop Brain Interchange System in Drug Resistant Epilepsy

What this research studies

You would get a small implanted Brain Interchange device that continuously records high-frequency brain signals (iEEG) from areas suspected to start seizures. Researchers will look for repeated, stereotyped high-frequency oscillation (HFO) waveforms that their earlier work found in seizure-onset zones and compare them to irregular HFOs from non-seizure areas. When the device detects those stereotyped HFOs, it would deliver brief stimulation to interrupt the abnormal activity in a closed-loop way. The team will track recordings, stimulation events, and clinical seizure outcomes to see if the implant can safely capture and modulate these seizure-related signals.

Who could benefit from this research

Good fit: Adults with drug-resistant focal epilepsy who are candidates for intracranial monitoring or an implantable neurostimulation system would be the ideal participants.

Not a fit: People whose seizures are well controlled with medication, those with primarily generalized epilepsy, or anyone who cannot undergo brain implantation or surgery are unlikely to benefit.

Why it matters

Potential benefit: If successful, the device could better target and interrupt seizure-generating brain activity and reduce seizures for people with drug-resistant epilepsy.

How similar studies have performed: Previous studies show HFOs can mark seizure onset zones and closed-loop stimulation can lower seizures, but using stereotyped HFO waveforms with an implantable Brain Interchange system is a novel, early approach.
