NIHSS
Pronunciation: NYE-hiss
Also written as: NIHSS — National Institutes of Health Stroke Scale
National Institutes of Health Stroke Scale, a standardized assessment tool for quantifying stroke severity and neurological deficits.
Full Definition
The National Institutes of Health Stroke Scale (NIHSS) is a systematic assessment tool used to objectively quantify the severity of neurological deficits in stroke patients. The scale evaluates multiple domains including consciousness, vision, motor function, sensation, speech, and language, with scores ranging from 0 (no deficit) to 42 (severe deficit). NIHSS scores are crucial for treatment decision-making, particularly regarding thrombolytic therapy eligibility, and serve as prognostic indicators for patient outcomes. In neuroradiology contexts, NIHSS scores often correlate with imaging findings and help guide urgent intervention decisions.
Usage
Usage note: Commonly used in stroke protocols; score should be specified when mentioned.
In Context
- "The patient's NIHSS score of 18 indicated severe stroke warranting immediate intervention." — Clinical assessment
- "Imaging findings were consistent with the NIHSS score of 12 documenting moderate left hemispheric deficits." — Radiology correlation
