Periodic Lateralized Epileptiform Discharges: A Child with a Rare Manifestation of Posterior Reversible Encephalopathy Syndrome and Literature Review.

This article discusses a rare case of a 10-year-old girl with posterior reversible encephalopathy syndrome (PRES) and associated periodic lateralized epileptiform discharges (PLEDs). PRES is a neurological disorder characterized by sudden onset of symptoms such as headache, altered consciousness, seizures, and visual impairments. The underlying cause of PRES is typically endothelial dysfunction triggered by various factors. Electroencephalography (EEG) plays a crucial role in evaluating encephalopathy and identifying nonconvulsive status epilepticus in patients with PRES. The article provides a comprehensive review of the existing literature on PRES-associated PLEDs. [Extracted from the article]
