Summary
Sporadic abnormalities are those that occur in singles, pairs or in abundance but are not repetitive. They indicate cortical dysfunction, but the central question is if they are epileptogenic. They key electrographic feature to classify the waveform is its sharpness Spike and sharp waves pointed in morphology and are typically epileptogenic, these terms are often used interchangeably. Slow waves are blunted in morphology and are typically not epileptogenic (except rhythmic focal slowing).
