What do NIHSS scores mean?

What do NIHSS scores mean?

A baseline NIHSS score greater than 16 indicates a strong probability of patient death, while a baseline NIHSS score less than 6 indicates a strong probability of a good recovery. On average, an increase of 1 point in a patient’s NIHSS score decreases the likelihood of an excellent outcome by 17%.

What is a good score for NIH stroke scale?

As a general rule, a score over 16 predicts a strong probability of patient death, while a score of 6 or lower indicates a strong possibility for a good recovery. Each 1-point increase on the scale lowers the possibility of a positive outcome for the patient by 17 percent.

Are mini strokes serious?

You might be having a transient ischemic attack (TIA), commonly referred to as a “mini stroke.” Don’t let the word “mini” fool you: transient ischemic attacks (TIA) are a serious condition warning you that a larger stroke may be coming- and soon.

How do you tell if a stroke is ischemic or hemorrhagic?

An ischemic stroke occurs when a blood vessel supplying the brain becomes blocked, as by a clot. A hemorrhagic stroke occurs when a blood vessel bursts, leaking blood into the brain.
