MMSE Following a 3-Stage Command 5 — Questions and Answers
Question 1: If a patient has a right-hand motor deficit (e.g., stroke), how should the examiner handle the instruction to 'take the paper in your right hand'?
- Insist the patient use the right hand and score accordingly
- Allow the patient to use the left hand and give full credit if other stages are completed (Correct answer)
- Skip the item and note it as untestable
- Score the item zero due to the physical limitation
Correct answer: Allow the patient to use the left hand and give full credit if other stages are completed
Clinical best practice allows accommodation for physical disabilities; the spirit of the task is command comprehension, and credit is given if the patient understands and executes the remaining steps.
Question 2: Which of the following patients would MOST likely score 3/3 on the 3-stage command despite significant cognitive impairment?
- A patient with severe Wernicke's aphasia
- A patient with mild depression and intact language (Correct answer)
- A patient with moderate Alzheimer's disease
- A patient with dense anterograde amnesia
Correct answer: A patient with mild depression and intact language
Mild depression with intact language and working memory would preserve command-following ability, while the other conditions directly impair the required cognitive mechanisms.
Question 3: In the context of MMSE scoring norms, a score of 1/3 on the 3-stage command is most consistent with what stage of cognitive impairment?
- Normal cognition
- Mild cognitive impairment
- Moderate dementia (Correct answer)
- Severe dementia
Correct answer: Moderate dementia
Completing only one of three stages typically indicates moderate impairment of working memory and executive function, consistent with moderate dementia.
Question 4: The 3-stage command was introduced in the MMSE to assess which aspect of language that simple naming tasks cannot evaluate?
- Word retrieval ability
- Comprehension of complex sequential verbal instructions (Correct answer)
- Phonological processing
- Syntactic production
Correct answer: Comprehension of complex sequential verbal instructions
Naming tasks assess word retrieval, while the 3-stage command specifically evaluates whether patients can comprehend and act upon multi-step verbal instructions.
Question 5: A caregiver reports that the patient follows simple 1-step instructions at home but struggles with preparing meals. Which MMSE finding would best correlate with this observation?
- Score of 3/3 on the 3-stage command
- Score of 0-1/3 on the 3-stage command (Correct answer)
- Normal orientation score
- Intact recall of 3 objects
Correct answer: Score of 0-1/3 on the 3-stage command
Failing multi-step commands on the MMSE correlates with inability to sequence complex daily activities like meal preparation, which require multi-step planning and execution.
Question 6: Which of the following is a key difference between the MMSE 3-stage command and an ideomotor apraxia evaluation?
- The MMSE uses written instructions while apraxia testing uses verbal ones
- The MMSE evaluates comprehension of a real-world action sequence, while apraxia testing focuses on pantomiming tool use on command (Correct answer)
- The MMSE 3-stage command requires drawing, unlike apraxia testing
- There is no meaningful difference between the two tasks
Correct answer: The MMSE evaluates comprehension of a real-world action sequence, while apraxia testing focuses on pantomiming tool use on command
Apraxia evaluation specifically tests learned skilled motor programs (e.g., pantomiming using a hammer), whereas the MMSE 3-stage command tests sequential instruction comprehension using everyday actions.
Question 7: A patient asks the examiner to repeat the 3-stage command immediately after it is given, before beginning the task. What should the examiner do?
- Repeat the command once to ensure the patient heard it
- Decline to repeat and instruct the patient to begin with what they remember (Correct answer)
- Write the stages on paper as a memory aid
- Score the item zero for the repetition request
Correct answer: Decline to repeat and instruct the patient to begin with what they remember
Standard MMSE protocol does not permit repetition of the command; the patient must proceed with what was heard to validly assess working memory and comprehension.
