Neuromodulation Using Low-intensity Focused Ultrasound for Potential Treatment for Medically Refractory Temporal Lobe Epilepsy
Neuromodulation Using Low-intensity Focused Ultrasound for Potential Treatment for Medically Refractory Temporal Lobe Epilepsy
This study is an invite only study looking at the effects of Low-Intensity Focused Ultrasound (LIFU) on epilepsy patients with implanted electrodes under the care of Dr. Shah.
This project will explore the use of Low-Intensity Focused Ultrasound (LIFU) as a non-invasive method to reduce seizures and potentially enhance cognitive functions in epilepsy patients. LIFU can target specific deep brain areas without surgery, offering an alternative to invasive procedures. The study focuses on patients who have an implanted Responsive Neurostimulation System (RNS). LIFU will be used to stimulate the entorhinal cortex, a brain region involved in both seizure activity and memory formation. Investigators are targeting the perforant pathway from EC to hippocampus, which primarily relies of layers II and III of EC. Therefore, this targeting will ensure that layers II and III of EC are within the beam profile of LIFU. During study visits, participant will receive non-invasive ultrasound stimulation in their brains. Investigators will measure seizure frequency and epileptic activity using the implanted RNS system to assess LIFU's effects for epilepsy. Neuropsychological and memory tests will be conducted before and after LIFU application to detect changes in cognitive functions. Investigators will compare results before and after stimulation to determine LIFU's effectiveness in reducing seizures and potentially improving memory or other cognitive functions.
