The<unk> , introduced in 1968, is one of the grading systems used to classify the severity of a subarachnoid hemorrhage based on the patient's clinical condition. It is used as a predictor of patient's prognosis/outcome, with a higher grade correlating to lower survival rate. Other<unk> s which describe the clinical presentation of subarachnoid hemorrhage patients include the World Federation of Neurosurgical Societies classification, which combines consciousness and motor deficit in its scoring. The<unk>  is named for Dr. William E.<unk>  (26 November 1921 - 26 January 1999) and Dr. Robert McDonald<unk>  (24 June 1931 - 3 October 2019)
