Small sharp spikes of sleep (SSS)

  • This waveform also is known as benign epileptiform transients of sleep (BETS).

  • These sharp, small waves occur on 1 or both sides (often asynchronously), especially in the temporal and frontal regions.

  • Rarely seen in children, they are seen most often in adults and the elderly. [7, 8] They can occur in epileptic patients but often are seen in healthy individuals. They can be regarded as a probable normal variant.
