MMSE Visuoconstructional Skills 4 — Questions and Answers
Question 1: When administering the pentagon copying task, what materials does the MMSE protocol require the examiner to provide?
- Graph paper and a ruler
- A blank piece of paper and a pencil or pen (Correct answer)
- A pre-printed form with a faint guide outline
- A tablet with a stylus for digital capture
Correct answer: A blank piece of paper and a pencil or pen
Standard MMSE administration provides plain white paper and a writing instrument; the examiner draws or presents the two pentagons for the patient to copy.
Question 2: A patient produces a copy where both pentagons have five angles but overlap so extensively that only one unified blob shape is visible. How should this be scored?
- Pass, because both pentagons have five sides
- Fail, because a four-sided intersection region is not discernible (Correct answer)
- Pass with notation of executive dysfunction
- Partial credit of 0.5 for effort
Correct answer: Fail, because a four-sided intersection region is not discernible
The intersection must produce a recognizable quadrilateral (four-sided) overlapping region; excessive overlap that destroys this region fails the criterion.
Question 3: Why is the visuoconstructional task placed near the end of the MMSE rather than at the beginning?
- To allow time for the patient to relax before attempting the hardest item
- To follow the traditional ordering developed in Folstein's original 1975 protocol (Correct answer)
- Because it requires a separate piece of paper, disrupting flow if done first
- It must follow orientation questions to calibrate baseline cognition
Correct answer: To follow the traditional ordering developed in Folstein's original 1975 protocol
Folstein's original 1975 MMSE placed construction near the end as part of the standardized sequence, which is preserved to maintain comparability across administrations.
Question 4: Which alternative cognitive screening tool also includes a visuoconstructional component but uses a clock face instead of pentagons?
- PHQ-9
- Montreal Cognitive Assessment (MoCA) (Correct answer)
- Geriatric Depression Scale (GDS)
- Confusion Assessment Method (CAM)
Correct answer: Montreal Cognitive Assessment (MoCA)
The MoCA includes both a clock-drawing task and a three-dimensional cube copy, providing a more comprehensive visuoconstructional assessment than the MMSE.
Question 5: A patient with Lewy body dementia attempts the pentagon copy. Which pattern of error is MOST consistent with this diagnosis?
- Perfectly accurate copy with no errors
- Severe constructional difficulty out of proportion to other cognitive scores (Correct answer)
- Minor tremor-related line irregularity only
- Perseverative drawing of extra pentagons
Correct answer: Severe constructional difficulty out of proportion to other cognitive scores
Dementia with Lewy bodies often shows disproportionately severe visuospatial and constructional deficits relative to memory impairment.
Question 6: If a low-literacy patient has never held a pencil before, how should the examiner handle the pentagon copying task?
- Skip the item and award no credit
- Administer it as usual and note low literacy as a confounding factor in interpretation (Correct answer)
- Replace it with a verbal description of the figure
- Award full credit to avoid penalizing for educational disadvantage
Correct answer: Administer it as usual and note low literacy as a confounding factor in interpretation
The task should still be administered per protocol, but the clinician must interpret results with awareness that low education and limited writing experience can lower scores independently of cognition.
Question 7: What is the maximum number of points a patient can earn on the entire MMSE 'Language and Praxis' domain, which includes the pentagon task?
- 5 points
- 9 points (Correct answer)
- 3 points
- 7 points
Correct answer: 9 points
The Language and Praxis section of the MMSE totals 9 points, covering naming, repetition, three-step command, reading, writing, and pentagon copying.
