1
Q

Guiding principle for Neuro Exam (3)

A
  1. IS mental status intact (able to answer questions)
  2. IS my patient able to partner with me to complete an accurate and reliable exam?
  3. Deficients may be transient/fluctuating (frustrating b/c answers may be different later in time)
2
Q

Framework

Are findings symmetric
