Quantitative EEG in typical absence seizures: a systematic review of spectral and entropy/complexity signatures.
BACKGROUND Typical absence seizures, the defining seizure type of childhood and juvenile absence epilepsy, are characterised by generalised 3 Hz spike-and-wave discharges and brief impairment of consciousness. Quantitative EEG (QEEG) offers spectral and entropy/complexity parameters beyond visual inspection, but the li...
