Clinical Context
A 34-year-old patient with medically refractory focal epilepsy is referred for implantation of a subscalp continuous bilateral electroencephalography (EEG) monitoring system to capture ambulatory seizures and interictal epileptiform activity. The device is implanted in a minor outpatient surgical setting or ambulatory surgery center under local anesthesia with sedation, and continuously records EEG data for up to 30 days. During the monitoring interval the patient continues daily activities at home and activates event markers as needed; data are periodically transmitted to the monitoring platform. The treating neurologist or epileptologist reviews the downloaded 30-day recording, uses automated spike and seizure detection tools to assist identification, visually inspects suspected events, interprets seizure types, lateralization and localization, quantifies spike burden, and prepares a formal report documenting findings, clinical correlation, and recommendations for the care team. Typical workflow steps include device implantation and programming, remote data acquisition, routine patient check-ins, clinician review and interpretation of recorded events, and generation of the clinical report for the referring physician and patient record.
