ELECTROENCEPHALOGRAPHIC CHANGES AND PROGNOSIS FOR THE DEVELOPMENT OF EPILEPSY IN PATIENTS WITH POSTERIOR REVERSIBLE ENCEPHALOPATHY SYNDROME (PRES): LITERATURE REVIEW

Posterior reversible encephalopathy syndrome (PRES) is an acute and usually reversible condition characterized by a rapid onset, convulsive syndrome, impaired consciousness, headache, visual impairment, nausea or vomiting, transient focal neurological signs, and arterial hypertension. Patients with PRES have changes in the white matter of the brain detected using magnetic resonance imaging; these changes are predominantly located in the occipital-temporal-parietal area. Increased blood pressure and severe metabolic disorders are the risk factors for PRES. Most of the patients have generalized tonic-clonic or focal seizures and epileptiform activity on the electroencephalogram during the acute period of PRES, but they do not develop epilepsy after this episode.
