Abstract:
1. A method of treating an acquired epileptic aphasia in a human patient by an implanted responsive neurostimulator, comprising: sensing electrical signals in a first region of a patient's brain, wherein the first region of the patient's brain is related to the acquired epileptic aphasia; determining if the patient is in a sleep state based on one or more of a time schedule, the sensed electrical signals, and the patient's metabolic activity; comparing the sensed electrical signals with electrical signals corresponding to at least one of background electrographic activity, and characteristics of epileptiform activity and electrographic seizures, to detect an occurrence of one or more of the following events: epileptiform activity, an electrographic seizure, an onset of an electrographic seizure, and a precursor to an electrographic seizure; responding to the occurrence of the one or more events by applying neurostimulation for treating the acquired epileptic aphasia to a second region of the patient's brain corresponding to a primary or associative language cortical region and a third region of the patient's brain, the third region being different from both the first region and the second region and corresponding to a region of the brain that mediates behavior and social interaction; and applying neurostimulation to the second region of the patient's brain if the patient is determined to be in a sleep state even in the absence of an occurrence of the one or more events.
