A Study to Evaluate fMRI of Active DBS Stimulation in Epilepsy

Not Applicable
Withdrawn
Conditions
Refractory Epilepsy
Registration Number
NCT04753983
Lead Sponsor
Mayo Clinic
Brief Summary

The purpose of this study is to use functional imaging to study the mechanisms of the anterior nucleus of the thalamus (ANT) deep brain stimulation (DBS).

Detailed Description

Researchers are testing how changing the settings on deep brain stimulation device (DBS) can help reduce the number and severity of seizures. Functional imaging will be used to study the mechanisms of ANT DBS to optimize the device settings to improve the degree of seizure reduction.
