Beyond the Diagnosis: Insight Into Posterior Reversible Encephalopathy Syndrome: A Case Series

Abstract An acute neurological condition known as posterior reversible encephalopathy syndrome (PRES) manifests as nonspecific symptoms such as headache, seizure, disorientation and visual abnormalities. PRES has been known for the last few decades, with characteristic radiologic findings, but the natural history of PRES has not yet been fully established. Although PRES is thought to be reversible, this may not always be true because there is a significant risk of neurological impairment and mortality. Here, we discuss three patients with different ages of PRES and a common association with hypertension. We observed different outcomes in these patients who were treated with antihypertensive, anticonvulsant, or supportive care agents.
