Hunt and Hess Classification of Subarachnoid Hemorrhage (SAH)
Classifies severity of subarachnoid hemorrhage based on symptoms, which predicts mortality.
Mild Headache, Alert and Oriented, Minimal (if any) Nuchal Rigidity
Full Nuchal Rigidity, Moderate-Severe Headache, Alert and Oriented, No Neuro Deficit (Besides CN Palsy)
Lethary or Confusion, Mild Focal Neurological Deficits
Stuporous, More Severe Focal Deficit
Comatose, showing signs of severe neurological impairment (ex: posturing)
