EEG of self-limited epilepsy with centrotemporal spikes (SeLECTS)

This 10-second segment shows the typical sharp waves of self-limited epilepsy with centrotemporal spikes (SeLECTS), previously known as benign epilepsy with centrotemporal spikes (BECTS). The sharp waves are markedly more frequent in sleep (stages I and II here) than in wakefulness. The morphology is typical with a duration of almost 200 ms and a high-amplitude aftergoing slow wave (as high as the sharp wave). The distribution is centrotemporal, and as in this example the sharp waves are often bilateral and independent. The dipole with frontal positivity is also typical and would be best shown on a referential montage.
