Toward More Rational Prediction of Outcome in Patients with High-grade Subarachnoid Hemorrhage

56 consecutive patients with altered mental status after subarachnoid hemorrhage, managed at a single institution.

Clinical grading using Glasgow Coma Scale (GCS), World Federation of Neurological Surgeons (WFNS) scale, and Hunt and Hess scale at various time points (admission, best before treatment, worst before treatment, immediately before treatment, and best within 24 hours after treatment).

Outcome at 6 months determined using a modification of the Glasgow Outcome Scale validated against the Karnofsky scale.hard clinical
