Hunt-Hess vs WFNS Grade Comparison for Subarachnoid Hemorrhage

Calculates and compares Hunt-Hess and WFNS (World Federation of Neurosurgical Societies) grading for aneurysmal subarachnoid hemorrhage. Hunt-Hess uses clinical symptoms (Grade I–V). WFNS uses GCS and motor deficit (Grade I–V). Both predict mortality and guide timing of aneurysm treatment.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.
