AI Seizure Detection with EEG

Electroencephalography records electrical activity from the brain using electrodes. During continuous monitoring, clinicians may review long recordings for seizures or other patterns. AI can identify candidate segments, estimate seizure likelihood, or help prioritize review. It does not observe every seizure directly: some events may not be captured during recording, and some clinical events may lack a clear scalp EEG correlate.

Artifacts from movement, electrode problems, or equipment can resemble abnormal patterns. A system trained on one dataset or patient group may miss events or produce frequent false alerts elsewhere. Alert thresholds trade off missed events and review burden. An automated label should direct attention to the EEG rather than replace interpretation by qualified clinicians. NINDS describes EEG and video monitoring as tools used to evaluate seizures, including to distinguish events that may look similar.

Hospitals should specify supported patients and recording conditions, monitor alerts and missed events, and define who responds. Evaluation should include seizure types, artifacts, age groups, medication contexts, and independent sites. Patients and caregivers should know monitoring tools do not guarantee detection of every event. An alert needs clinical review; absence of an alert does not rule out epilepsy or eliminate evaluation. Monitoring is generally ordered for a clinical reason, and the team should account for the difference between the patient’s observed behavior and what appears in the electrical recording. Communicate uncertainty promptly to the responsible clinician and document whether an event was captured.
