Clinical calculators
Neurology Calculators
Neurology calculators cover stroke severity, transient-ischemic-attack risk-factor scoring, and subarachnoid-hemorrhage grading. Each belongs to a distinct disease and assessment context.

Stroke deficit scoring
NIH Stroke Scale (NIHSS) CalculatorCalculate the standard adult NIH Stroke Scale from all 15 scored entries, with a 0–42 total, permitted untestable-item documentation, and item-level results.Post-TIA historical risk score
ABCD² Score (TIA)Calculate the standard 0–7 ABCD² score from age, initial blood pressure, clinical features, symptom duration and diabetes, with component-level results and modern triage limitations.Subarachnoid hemorrhage clinical grade
Hunt & HessHunt and Hess Scale for Subarachnoid Hemorrhage (SAH)Look up and select the traditional five-grade Hunt and Hess clinical presentation scale for aneurysmal subarachnoid hemorrhage from one documented examination.Important limits
- ABCD² cannot diagnose TIA or independently determine investigation, admission, or discharge.
- NIHSS may not capture every clinically important neurologic deficit or posterior-circulation presentation.
- Hunt-Hess does not establish subarachnoid hemorrhage and does not select treatment.
