Transdermal opioid patch in treatment of paroxysmal autonomic instability with dystonia with multiple cerebral insults: A case report.

A patient diagnosed with PAID following multiple cerebral insults was observed, whose condition was controlled by application of opioid patch rather than by intravenous or oral routes. A transdermal opioid patch, such as fentanyl patch, can thus be effective in the treatment of patients with PAID following multiple cerebral insults.
