Final answer:

The NIHSS is used to evaluate the impact of a stroke on areas such as level of consciousness, visual function, facial palsy, motor and sensory functions, and language and speech, including the potential for aphasia and dysarthria.

Step-by-step explanation:

The National Institutes of Health Stroke Scale (NIHSS) is used to evaluate various areas of neurological function after a stroke. The scale assesses several domains to understand and quantify the impact of a stroke on a patient. These areas include:

  • Level of consciousness: This component examines alertness and responsiveness.
  • Visual function: This part measures the patient's ability to see in all quadrants and their gaze.
  • Facial palsy: It assesses facial symmetry and motion.
  • Motor function: This section evaluates the strength of the arms and legs.
  • Sensory function: The patient's capacity to feel sensations is examined.
  • Language and speech: The NIHSS looks at the patient’s ability to speak and understand language, which includes screening for aphasia and dysarthria.
  • Neglect: It determines if the patient lacks awareness of one side of space, which is common after certain types of strokes.

Other functions such as hearing are not directly assessed by the NIHSS, but could be impacted by a stroke and evaluated through different examinations. The scale is widely used by healthcare professionals for both initial assessment and ongoing monitoring of stroke severity.
