NIH Stroke Score Calculator (NIHSS Scale )
Disclaimer: Diagnosis is usually made clinically. If the score from the calculator indicates that you might be at risk please consider visiting a doctor for further evaluation.
Stroke, a medical disorder in which insufficient blood flow to the brain results in cell death, happens when something limits blood supply to part of the brain or when a blood artery in the brain breaks. Ischemic and hemorrhagic strokes, which relate to blood flow or bleeding , are two different types of strokes. Both freeze certain brain functions in their tracks.
Stroke signs and symptoms might include difficulty speaking or recognizing, dizziness, or a loss of vision on one side of the body. On one side of the body, it may also be difficult to move or feel. It is common for symptoms and signs of a stroke to appear quite fast.
The NIH Stroke Scale, which was created via research funded by the National Institute of Neurological Disorders and Stroke (NINDS), assists medical professionals in determining the severity of a stroke. By having the patient respond to questions and complete several physical and mental tests, doctors utilize the NIH Stroke Scale to evaluate neurological function and disabilities.
The NIHSS consists of 11 items, each of which is scored between 0 and 4 for a particular skill. In general, a score of 0 for each item shows normal function in that particular skill, whereas a higher number denotes some degree of disability.
Components of NIHSS:
- Level of consciousness
- Horizontal eye movement
- Visual field test
- Facial palsy
- Motor weapon
- Engine leg
- Limb ataxia
- Sensory
- Language
- Speech
- Extinction and inattention
Evaluation of score :
- 0 points are considered : No stroke symptoms
- 1–4 points are considered : Minor stroke
- 5–15 points are considered : Moderate stroke
- 16–20 points are considered : Moderate to severe stroke
- 21–42 points are considered : Severe stroke
