A Pilot Study: Focused Ultrasound Thalamotomy for the Prevention of Secondary Generalization in Focal Onset Epilepsy

Brief Summary

The purpose of this study is to assess the safety and feasibility of unilateral focused ultrasound thalamotomy in adults with focal onset epilepsy whose medicines are not working well. The ExAblate (ExAblate) transcranial system is the name of the device that will be used to create and send ultrasound waves through the scalp and skull precisely to a small structure located in the center of the brain. This structure is known as the "Anterior Nucleus", and is an important region in the brain that may cause seizures. Safety will be measured by recording and analyzing the frequency of side effects throughout participation. Feasibility will be measured by the ability to create a lesion in the anterior nucleus.
