RESUMO
Paroxysmal sympathetic hyperactivity (PSH) is a clinical syndrome of episodic sympathetic hyperactivities following severe acquired brain injury. It is characterized by paroxysmal hyperthermia, tachycardia, hypertension, tachypnea, excessive diaphoresis, and specific posturing. Although the persistence of PSH increases the risk of several adverse events and worsens the prognosis, pharmacological treatments for PSH have not yet been clearly established. We report the valuable case of a 60-year-old man who developed PSH following hypoxic encephalopathy, which was effectively treated with a combination therapy of gabapentin and guanfacine. The present case suggests that combination therapy with gabapentin and guanfacine may be a therapeutic option for PSH.
