SYSTEM AND METHOD FOR SEIZURE DETECTION AND AUTOMATED THALAMIC STIMULATION

摘要

A thalamic medical device system and method enables automated detection of epileptic seizures and optionally providing contingent thalamic stimulation triggered by automated seizure detection. The method includes detecting electrical signals in a frequency band of 8-42 Hz from an anterior thalamic nucleus or a centro-median thalamic nucleus in a first hemisphere and/or a second hemisphere of a brain with one or more electrode assemblies surgically implanted at least partially within an anterior thalamic nuclei or a centro-median thalamic nuclei, and outside of a subthalamic nuclei of the patient. The method also includes transmitting the detected electrical signals to a medical device, analyzing them using a seizure detection algorithm, and delivering electrical stimulation to the anterior thalamic nuclei or centro-median thalamic nuclei in the first hemisphere and/or the second hemisphere via the electrode assemblies in response to a seizure detected by the medical device.
