Case Report: Paroxysmal autonomic instability with dystonia syndrome: a rare complication of tuberculous meningitis

Abstract

Paroxysmal autonomic instability with dystonia syndrome (PAIDS) is a rare and life-threatening complication of neurologic diseases. We report the case of a 20-year-old male with acute severe brain damage from tuberculous meningitis, who eventually developed paroxysmal episodes of spontaneous and inducible tachycardia, tachypnea, hypertension, and decerebrate posturing. We diagnosed the patient as suffering from paroxysmal autonomic instability with dystonia syndrome. The unavailability of morphine and the prohibitive cost of prolonged fentanyl use led to a trial of gabapentin, clonazepam, and propranolol for the patient, resulting in symptom resolution. Brain injury causes dysfunction of autonomic centers leading to paroxysmal autonomic instability with dystonia syndrome. Management includes minimizing stimulation and pharmacotherapy with preventive and abortive medications. Alternatives like gabapentin, propranolol and clonazepam were effective in treating the paroxysmal episodes, proving that they may have a role in resource limited settings. PAIDS requires urgent recognition and treatment to prevent further complications and death.
