How this tool works
The Hunt and Hess scale (1968) stratifies patients with aneurysmal subarachnoid hemorrhage by clinical state at presentation: grade I asymptomatic or minimal headache; grade II moderate-to-severe headache and nuchal rigidity with at most a cranial nerve palsy; grade III drowsiness, confusion or mild focal deficit; grade IV stupor and moderate-to-severe hemiparesis; grade V deep coma with decerebrate posturing. In the original description, serious systemic disease or angiographic vasospasm advances the patient to the next higher grade. The scale remains a standard descriptor of admission status and a prognostic indicator, complementing imaging scales such as Fisher and modified Fisher.
