The Impact of Focused Ultrasound Thalamotomy of the Anterior Nucleus for Focal-Onset Epilepsy on Anxiety

The purpose of this study is to evaluate the feasibility, safety, and effects on anxiety of high intensity focused ultrasound ablation (FUSA) in patients suffering from treatment-refractory focal epilepsy and anxiety. FUSA is a non-invasive neurosurgical procedure that uses ultrasound waves, sent directly through the scalp and skull, to precisely target small abnormal areas of the brain. For this study, the targeted area of the brain is the anterior nucleus of the thalamus. This brain region may cause seizures and may also be involved in anxiety. The study will test if FUSA is safe and tolerated, and if it reduces anxiety and brain response to threat in patients with anxiety receiving the procedure for partial-onset epilepsy that is resistant to medications.
