Accuracy of a wearable seizure detection device in focal epilepsy

  • A wearable electroencephalogram (EEG) device demonstrated a focal seizure detection sensitivity of 52% in inpatient and 23% in outpatient settings.
  • This wearable seizure detector device demonstrated low positive predictive value (0.11% for inpatients, 0.04% for outpatients) and was associated with high false alarm rates (7.13/hour for inpatients; 7.77/hour for outpatients).
  • Signal quality improved at night leading to the identification of non-reported nighttime seizures. Despite this, the authors concluded that the relatively poor performance metrics would limit widespread clinical application at this time.
