Typical absence seizures are brief (lasting seconds) generalized nonmotor epileptic seizures with an abrupt onset and termination ( 1, 2).

For EEG recordings sampled at 250 Hz, the one-channel processing speed for midrange smartphones running Android 10 (about 0.2 s per 1 min of EEG) was high enough for real-time seizure detection. The overlap of automatically detected seizures with the actual seizures was equal to ~96%. When the duration threshold was raised to 3 s, the false detection rate fell to 0.5/h. In the patients, all false detections were associated with epileptiform discharges, which did not yield clinical manifestations. For seizures lasting longer than 2 s, the detector, which analyzed two bipolar EEG channels (Fp1-T3 and Fp2-T4), achieved a sensitivity of 97.6% with 0.7/h detection rate. We used a dataset containing EEGs from 64 patients (37 h of recordings with almost 400 seizures) and 30 age and sex-matched controls (9 h of recordings) for development and testing. Herein, we present a novel absence detection algorithm based on the properties of the complex Morlet continuous wavelet transform of SWDs. The potential benefits of this kind of monitoring include facilitating diagnosis, personalized drug titration, and determining the duration of pharmacotherapy.

The appearance of low-cost, portable EEG devices has paved the way for long-term, remote monitoring of CAE and JAE patients.

This type of seizure is severe in two common pediatric syndromes: childhood (CAE) and juvenile (JAE) absence epilepsy. Transient impairment of consciousness and spike-slow wave discharges (SWDs) in EEG are their characteristic manifestations.
