NIHSS — National Institutes of Health Stroke Scale

Calculate the NIH Stroke Scale (NIHSS) across 11 neurological domains to quantify acute stroke severity, determine thrombolysis eligibility, guide thrombectomy decisions, and predict functional outcomes.

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.

How It Works

Calculate the NIH Stroke Scale (NIHSS) across 11 neurological domains to quantify acute stroke severity, determine thrombolysis eligibility, guide thrombectomy decisions, and predict functional outcomes

Each component has a specific meaning:

  • 11 neurological domains — The 11 neurological domains recorded for the scenario being assessed.

Note: Interpret the nihss score result against the thresholds and context described above.

How to Use

Enter the 11 neurological domains for the scenario you are assessing. Calculate the NIH Stroke Scale (NIHSS) across 11 neurological domains to quantify acute stroke severity, determine thrombolysis eligibility, guide thrombectomy decisions, and predict functional outcomes. Use the nihss score result to inform your calculation.
