Hunt and Hess grading system

The Hunt and Hess scale describes the clinical severity of subarachnoid hemorrhage resulting from the rupture of an intracerebral aneurysm and is used as a predictor of survival.

• grade 1
  • asymptomatic or minimal headache and slight neck stiffness
  • 70% survival
• grade 2
  • moderate to severe headache; neck stiffness; no neurologic deficit except cranial nerve palsy
  • 60% survival
• grade 3
  • drowsy; minimal neurologic deficit
  • 50% survival
• grade 4
  • stuporous; moderate to severe hemiparesis; possibly early decerebrate rigidity and vegetative disturbances
  • 20% survival
• grade 5
  • deep coma; decerebrate rigidity; moribund
  • 10% survival

History and etymology

It was first described in 1968 by two neurosurgeons from Ohio, USA:

• William Edward Hunt (1921-1999), neurologist and neurosurgeon; also of Tolosa-Hunt syndrome
• Robert M Hess (fl. 2018) neurosurgeon
