Study on diagnosis and assessment of acute stroke using national institute of health stroke scale(NIHSS)

Abstract

Background: Stroke, previously known as cerebrovascular accident (CVA), is now more 
accurately termed as a "brain attack" to emphasize its acute and potentially debilitating 
nature. It is defined as a sudden episode of focal neurological dysfunction persisting for more 
than 24 hours. Between 15% to 30% of stroke survivors experience permanent disability, and 
up to 20% require institutional care months after their stroke. The economic and 
psychological burdens associated with stroke are substantial, affecting individuals, families, 
and healthcare systems
