Hunt and Hess grade: clinical severity of aneurysmal subarachnoid haemorrhage (SAH) on presentation, from symptoms and level of consciousness.
Classification
| Category | Description |
|---|---|
| Grade 1 | no symptoms or mild headache, slight neck stiffness. |
| Grade 2 | moderate to severe headache, neck stiffness; no neurological deficit other than a cranial nerve palsy. |
| Grade 3 | drowsiness or confusion; mild focal deficit. |
| Grade 4 | stupor; moderate to severe hemiparesis; possibly early decerebrate posturing and autonomic disturbance. |
| Grade 5 | deep coma, decerebrate posturing, moribund appearance. |
| Modifier | serious systemic disease (e.g. hypertension, diabetes, severe atherosclerosis, chronic lung disease) or severe vasospasm on angiography moves the patient one grade worse; this rule is applied inconsistently in practice. |
