Posterior reversible encephalopathy syndrome (PRES) is a recently described variant of hypertensive encephalopathy characterized by headache, visual disturbances and altered mental function. Its causes are diverse and in contrast to hypertensive encephalopathy, it can develop without significant elevation of blood pressure. This syndrome is mostly reversible when correctly managed; however, failure to recognize it can lead to cerebral infarction and death.

Posterior reversible encephalopathy syndrome (PRES) is a neurologic condition defined by symptoms and imaging findings secondary to vasogenic edema in the brain. Even though not all hypertensive individuals will progress to PRES, high blood pressure is the most frequent risk factor associated with the condition. The pathophysiology of PRES is not clearly understood, but the most accepted proposed mechanism focuses on the brain's inability to regulate cerebral blood flow through constriction or dilation of vessels during extreme blood pressure.

Introduction: Preeclampsia and eclampsia are hypertensive disorders of pregnancy associated with significant maternal and fetal morbidity and mortality. Posterior reversible encephalopathy syndrome (PRES) is a neurological complication observed in these conditions, yet its impact on fetomaternal outcomes remains underexplored. The aim of this study is to investigate the association between PRES and fetomaternal outcomes in women with preeclampsia and eclampsia.

Background: Children born to women with hypertension during pregnancy have a two to threefold increased risk of developing cognitive disorders compared to children born to women without hypertension. However, structural changes in the central nervous system of these children remain poorly understood. We aim to compare the brain histological findings from autopsies of neonates and fetuses born to women with and without hypertension during pregnancy.

Complication after carotid artery revascularization is mainly represented by stroke. Reversible cerebral vasoconstriction syndrome triggering by carotid artery revascularization is exceptional but it is an unrecognized aetiology of stroke. It could be associated with brain edema and henceforth, a posterior reversible encephalopathy syndrome can be confused with post-carotid artery revascularization cerebral hyperperfusion syndrome.
