Posterior reversible encephalopathy syndrome (PRES) is a reversible syndrome accompanied by neurological and radiological findings. First in 1996 Hınchey J and ark. This syndrome, which is defined by, has often passed into literature as a reversible disease accompanied by hypertension, headache, confusion, convulsion, swelling and vision disorders. There are two hypotheses in patophysiology, the first is cerebral hyperperfusion and related vasogenic swelling due to sudden rise in pressure, and the second is endothelial dysfunction caused by endogenous and exogenous toxins. It is clinically caregated with a variety of neurological symptoms, and can develop acute or subacute. It can take days and weeks as it can take a few hours. Tools and Methods; This study was conducted retrospectively between the years 2012-2017 among patients applying for Emergency Service at the University of Namiyaman School of Medicine. Acute initial neurological symptoms, including headache, encephalopathy, stroke, vision disorder or focal neurological defect, and five PRES phenomena identified in focal vasogenic swelling in brain imaging were taken to study. Facts were classified according to age, gender, emergency service application complaint,chronic disease, pregnancy status, BBT,MR and electroencephalographic (EEG) findings. As a result, the pres should be considered in women and pregnancies who apply for emergency service with headaches, loss of vision, loss of consciousness and especially convulsion. Keywords: PRES, emergency service, convulsion ABSTRACT Background: Posterior reversible encephalopathy syndrome (PRES) is a reversible syndrome accompanied by neurological and radiological findings by Hynchy J et al. in 1996.  This syndrome is often referred with hypertension, headache, confusion, convulsions, vomiting, and loss of vision. The first being cerebral hyperperfusion due to suddenly elevated blood pressure and the associated vasogenic edema and the second endothelial dysfunction caused by endogenic and exogenous toxins. It is clinically characterized by various neurological findings that may develop acutely or subacutely.  It can last for several hours or days and weeks. Material and method: This study was retrospectively performed between 2012-2017. Acute onset neurological symptoms including headache, encephalopathy, seizure, visual impairment or focal neurological deficit, and five PRES cases with focal vasogenic edema on brain imaging were included in the study. The cases were classified according to age, gender, complaint of emergency service, chronic disease, pregnancy status, BBT, MR and electroencephalographic (EEG) findings. Conclusion: As a result; emergency headaches, visual loss, loss of consciousness, and PRES in women and pregnant women, especially those who are referred for convulsions. Keywords: pres, emergency, convulsions
