A neuropsychologist adapts the MoCA for a patient with dyscalculia. Which accommodation is most consistent with standard MoCA guidelines?
Answer: Skip serial 7s and note the omission
Standard MoCA protocol does not have an official alternative for serial 7s; skipping and noting it preserves score integrity.
What is the expected answer after subtracting 7 from 93 twice?
Answer: 79
93 − 7 = 86, then 86 − 7 = 79; two subtractions from 93 yield 79.
During a MoCA administration, a patient spontaneously self-corrects a serial 7s error. How should the examiner score this?
Answer: Count it as correct because the final answer is right
If the patient self-corrects to the right answer, MoCA scoring guidelines count it as correct.
Which patient profile is most likely to score 0 on the MoCA serial 7s while scoring normally on other sections?
Answer: A patient with isolated severe attentional deficits
Severe attentional deficits specifically impair the working memory demands of serial 7s without necessarily affecting other domains.
If a MoCA patient scores 2 on serial 7s, what is the minimum number of correct subtractions they achieved?
Answer: 2
A score of 2 corresponds to 2–3 correct subtractions; the minimum to earn 2 points is 2 correct.
What is 72 minus 7?
Answer: 65
72 minus 7 equals 65, the final number in the MoCA serial 7s sequence.
Why does the MoCA use serial 7s starting from 100 rather than a simpler arithmetic task?
Answer: To place sufficient cognitive load on attention and working memory
Starting from 100 and subtracting 7 repeatedly requires sustained attention and working memory, the domains being assessed.
