✦ Synopsis
This report evaluates a method using analog EEG signal preprocessing and a minicomputer for quantifying certain spike-wave EEG patterns that occur in patients suffering from petit ma1 epilepsy. EEGs were recorded during 10-12 hr in each of five awake patients. A single frontocentral EEG channel was analyzed on-line by the computer system, which detected 628 abnormalities. A graphic multichannel tracing was visually evaluated off-line by two electroencephalographers working independently. There was good agreement between the computer outputs and both electroencephalographers in detecting spike-wave patterns occurring in clinically manifest seizures. However, agreement between computer and human interpretation was much lower than agreement between the electroencephalographers themselves for less prominent spike-wave discharges. This pilot study indicates that multichannel EEG signal processing is required for comprehensive quantitative detection of clinically significant, generalized spike-wave patterns.
