Paroxysmal sympathetic hyperactivity syndrome after recurrent stroke: A case report

Abstract

Paroxysmal sympathetic hyperactivity (PSH) is a state of autonomic dysfunction characterized by symptoms such as tachypnea, tachycardia, hypertension, hyperthermia, sweating, and dystonia. It can occur after traumatic brain injury, hypoxic-ischemic encephalopathy, and diseases such as stroke. Hypoxia, extensive axonal damage, and young age are believed to predispose to the development of PSH. These patients may be diagnosed with pulmonary embolism, septicemia, or epileptic seizures. Delays in diagnosis prolong hospital stay. Here, we present an 81-year-old man who developed PSH after a recurrent stroke and our management.
