Ischemic Stroke
How severe is my patient’s stroke?
Assess stroke severity using a clinical exam (NIHSS or mNIHSS) or quantify infarct burden on CT with ASPECTS to guide treatment decisions.
Diagnosis
Prognosis
NIH Stroke Scale/Score (NIHSS)
Widely used, standardized stroke severity score
Use this tool when
Needing a standardized stroke severity assessment
Diagnosis
Prognosis
Modified NIH Stroke Scale/Score (mNIHSS)
Faster, simpler stroke severity (relative to NIHSS)
Use this tool when
Needing a fast, simplified stroke severity assessment
Prognosis
Alberta Stroke Program Early CT Score (ASPECTS)
Imaging-based guidance for stroke treatment decisions
Use this tool when
Reviewing imaging in acute ischemic stroke
