MMSE Attention and Calculation 2

Question 1

A patient is asked to count backward from 100 by 7s. After '93', they say '87'. How many errors have they made?

Accepted Answer

One error (correct answer was 86)

Answer

100 minus 7 is 93, and 93 minus 7 is 86, so saying 87 constitutes one serial subtraction error.

Question 2

Which alternative task is commonly substituted for serial 7s when a patient has limited education?

Spell 'WORLD' backward

Answer

Spelling 'WORLD' backward is the standard MMSE alternative to serial 7s for individuals with limited formal education.

Question 4

A patient correctly completes three of the five serial 7 subtractions. What score do they receive for this section?

Accepted Answer

3 out of 5

Answer

Each correctly executed serial subtraction step earns 1 point, so three correct steps yield a score of 3.

Question 5

Why is the serial 7s task considered a measure of attention rather than pure arithmetic ability?

It requires sustained concentration and working memory while calculating

Serial 7s demands holding a running total in working memory while performing repeated subtraction, making sustained attention essential.
