At the beginning, management plan for the patients solely depended on the grade of the applied grading system but after introduction of CT and microscope into the diagnosis and surgery for the aneurysmal subarachnoid hemorrhage and better understanding and management of vasospasm, the role of grading system has been changed to emphasize more on the predictability of the postsurgical outcome. The author reviewed the most popular and widely used grading systems to figure out their significance in predicting outcome and clinical applicability.

2 Table 1. Botterell s original grading system Grade 1conscious patient with or without signs of blood in subarachnoid space Grade 2drowsy patient without significant neurological deficit Grade 3drowsy patient with neurological deficit probable intracerebral clot Grade 4patient with major neurological deficit, deteriorating because of large intracerebral clots, or older patients with less severe neurological deficit but preexisting degenerative cerebrovascular disease Grade 5moribund or nearly moribund patient with failing vital centers and extensor rigidity Table 2. Nishioka s grading system Grade symptom freecompletely recovered from the effects of the last hemorrhage Grade minimally illcomlaining of headache but alert and responsiveno major neurological deficit Grade moderately illa lethargic with headache, neck stiffness but without hemspheric neurologic deficitb alert, recovered from the general effects of subarachnoid hemorrhage but having a hemisheric neurologic deficit Grade seriously illa severely obtunded without major neurologic deficitb lethargic or poorly responsive with hemispheric deficithemiparesis, dysphasia, mental confusion Grade moribunddecerebrate or unresponsive to all stimuli Table 3. Hunt and Hess classification Grade asymptomatic, or minimal headache and slight nuchal rigidity Grade moderate to severe headache, nuchal rigidity, no neurological deficit other than cranial nerve palsy Grade drowsiness, confusion, or mind focal deficit Grade stupor, moderate to severe hemiparesis, possibly early decerebrate rigidity and vegetative disturbances Grade deep coma, decerebrate rigidity, moribund appearance Table 4. Hunt and Kosnik classification Grade 0unruptured aneurysm Grade asymptomatic, or minimal headache and slight nuchal rigidity Grade ano acute meningeal or brain reaction, but with fixed neurological deficit Grade moderate to severe headache, nuchal rigidity, no neurological deficit other than cranial nerve palsy Grade drowsiness, confusion, or mild focal deficit Grade stupor, moderate to severe hemiparesis, possibly early decerebrate rigidity and vegetative disturbances Grade deep coma, decerebrate rigidity, moribund appearance Table 5. Botterell s modified grading system Grade 1minimal bleed alert, no neurological deficit Grade 2mild bleed alert, minimal neurological deficit as a third nerve palsy, stiff neck Grade 3moderate bleed drowsy or confused, stiff neck, with or without neurological deficit Grade 4moderate or severe bleed semi-coma, with or without neurological deficit Grade 5severe bleed coma and decerebrate movement Kor J Cerebrovascular Disease 2:24-9,
