  • 0 for absent
  • 1 for present
Inattention Say to the patient, “I am going to read you a series of 10 letters. Whenever you hear the letter “A”, indicate by squeezing my hand.” Read letters from the following letter list in a normal tone 3 seconds apart. “SAVEAHAART” (Errors are counted when patient fails to squeeze on the letter “A” or when the patient squeezes on any letter other than “A.”)
  • 0 for absent (correct 8 or more)
  • 1 for inattention (correct 4-7)
