Simplified National Institutes of Health Stroke Scale (sNIHSS)

Abbreviated 6-item version of the NIHSS for rapid stroke severity assessment. Correlates well with full NIHSS for triage and thrombolysis decisions.

Used in: Stroke & TIA

Score interpretation

Minor stroke

→ Consider IV tPA eligibility; NIHSS-guided thrombolysis

Moderate stroke

→ IV tPA + thrombectomy evaluation; stroke unit admission

Moderate-severe stroke

→ Mechanical thrombectomy assessment; urgent neurovascular imaging

Severe stroke

→ Emergency thrombectomy; intensive monitoring; goals of care discussion

Interpretation bands for the sNIHSS. Apply clinical judgement and local guidance.
