Abstract: A method of assessing electrical activity of a brain includes, for each of a plurality of electrical-activity records of the brain, applying a machine-learned ESC model to the record to classify the record as one of a seizure record or a non-seizure record, wherein each of record is sensed by a corresponding one of a plurality of sensing channels of an implanted medical device; for each seizure record in a set of seizure records, applying the machine-learned ESC model to the seizure record to classify the seizure record as one of a local-seizure record or a spread-seizure record, wherein the seizure record comprises a first seizure record captured by a first sensing channel and a second seizure record captured by a second sensing channel; and for each spread-seizure record in a set of spread-seizure records, applying a machine-learned SSC model to the spread-seizure record to classify the spread-seizure record as a type of seizure spread pattern.
