The score for each ability is a number between 0 and 4, 0 being normal functioning and 4 being completely impaired. The patient’s NIHSS score is calculated by adding the number for each element of the scale; 42 is the highest score possible. In the NIHSS, the higher the score, the more impaired a stroke patient is.
