A multicenter, video‐ EEG ‐based validation of a multimodal wearable device for focal seizure detection in adults: The SeizeIT2 study

Wearable devices may help improve seizure detection in people with epilepsy, but few non-invasive options exist for detecting focal seizures. We studied a behind-the-ear wearable device (Sensor Dot) using automated analysis combined with expert review. Overall, this approach resulted in detection of seizures with low sensitivity but high precision. Post-hoc subgroup analysis suggested that for seizures characterized by a distinct ictal EEG pattern and tachycardia-features often seen in temporal lobe epilepsy-this multimodal approach achieved a sensitivity of 0.74. Further prospective validation is required to confirm if this performance can be replicated through pre-monitoring patient selection.
