Risk factors and clinical outcomes of basilar artery occlusion presenting with paroxysmal sympathetic hyperactivity as the initial manifestation: a prospective study.

Background: Paroxysmal sympathetic hyperactivity (PSH) has been linked to a worse clinical prognosis in patients with traumatic brain injury. We aimed to identify the risk factors and clinical features associated with basilar artery occlusion (BAO) presenting with PSH as the first clinical presentation.

Methods: This study recruited patients with acute BAO who received endovascular therapy (EVT) at two stroke centers in China.
