Synonyme: PLED (Periodic lateralized epileptiform discharges)

*'''L'''ateralized: so unilateral
*'''P'''eriodic: Relative constant interval between the discharges, which varies between 0.5 and 3 seconds (most often around 1 second)
*'''D'''ischarge: Could be a [[Delta waves]] or sharp waves with a “epileptiform” morphology

*LPD’s are seen in acute cerebral laesion
** Non specific:
***Acute cerebrovascular events
***Encephalitis
***Subdural hematoma
***Other structural lesions
* Tend to disappear in weeks
* Higher risk of seizures in patients with LPD’s
