Abstract:
1. A method comprising: delivering a therapy from a medical device to a patient to treat a non-respiratory neurological disorder of the patient via a lead positioned within a brain of the patient; sensing electrical activity of the brain of the patient, during the therapy of the patient, with at least one electrode of the lead positioned within the brain of the patient, the at least one electrode being in communication with the medical device; determining sleep states of the patient based on the sensed electrical activity of the brain of the patient, wherein determining the sleep states of the patient includes comparing the relative power levels of different frequency bands of the sensed electrical activity of the brain of the patient; determining values of a sleep quality metric based on the sleep states of the patient determined based on the electrical activity of the brain of the patient; and providing the sleep quality metric values to a user for evaluation of the therapy.
