The NIHSS Calculator is a vital online tool for healthcare professionals to rapidly and precisely assess the severity of an acute stroke and quantify associated neurological deficits. This standardized National Institutes of Health Stroke Scale (NIHSS) provides a critical score that aids in diagnosis, patient management, treatment planning, and predicting patient outcomes after a stroke event.
Formula:
The National Institutes of Health Stroke Scale (NIHSS) total score is derived by summing the individual scores from 11 distinct neurological examination items. Each item is scored on a predefined scale (e.g., 0-4), where a higher score signifies greater impairment for that specific neurological function.
Total NIHSS Score = ∑ (Score for each of the 11 NIHSS items)
Note: For items where assessment is not possible due to pre-existing conditions (e.g., amputation), a score of 0 is typically assigned, but the condition is noted.
