MMSE Visuoconstructional Skills 2 — Questions and Answers
Question 1: On the MMSE visuoconstructional task, what specific geometric shape must a patient copy to receive credit?
- Two overlapping pentagons (Correct answer)
- A cube drawn in 3D perspective
- Intersecting triangles forming a star
- A circle divided into four quadrants
Correct answer: Two overlapping pentagons
The MMSE requires copying two intersecting pentagons, and the copy must preserve all angles and the overlapping region.
Question 2: Which of the following would cause a patient to FAIL the MMSE pentagon copying task?
- Drawing pentagons slightly smaller than the original
- Omitting one angle from a pentagon so it has only four sides (Correct answer)
- Using a slightly shaky line due to tremor
- Placing the figures closer together than shown
Correct answer: Omitting one angle from a pentagon so it has only four sides
Each pentagon must have exactly five angles; omitting one makes it a quadrilateral, which fails the task.
Question 3: A patient with parietal lobe damage attempts the pentagon task. Which error pattern is most characteristic of left-sided neglect?
- Drawing only the right half of both pentagons (Correct answer)
- Rotating the entire figure 90 degrees
- Adding extra angles to each pentagon
- Drawing the figures mirror-imaged
Correct answer: Drawing only the right half of both pentagons
Hemispatial neglect from right parietal lesions causes patients to omit the left side of the copied figure.
Question 4: The MMSE visuoconstructional item is worth how many points toward the total score of 30?
- 3 points
- 2 points
- 1 point (Correct answer)
- 5 points
Correct answer: 1 point
The pentagon copying task is a single 1-point item within the MMSE's 30-point total scale.
Question 5: Which cognitive domain is the pentagon copying task on the MMSE primarily designed to assess?
- Verbal fluency
- Visuoconstructional ability (Correct answer)
- Episodic memory
- Executive planning
Correct answer: Visuoconstructional ability
Pentagon copying tests the patient's ability to perceive and reproduce a spatial construction, reflecting visuoconstructional skill.
Question 6: When scoring the pentagon task, a clinician notices the patient's copy has all ten angles but the two figures do not overlap. How should this be scored?
- Full credit, because all angles are present
- No credit, because the intersection is missing (Correct answer)
- Half credit for the angles
- Pass with a note about mild impairment
Correct answer: No credit, because the intersection is missing
Both correct angles AND an overlapping four-sided region are required; absence of the intersection means the item is failed.
Question 7: Which disease is most associated with early impairment on the MMSE pentagon copying task due to posterior cortical involvement?
- Frontotemporal dementia
- Alzheimer's disease (Correct answer)
- Huntington's disease
- Normal pressure hydrocephalus
Correct answer: Alzheimer's disease
Alzheimer's disease commonly affects posterior parieto-occipital regions early, producing visuoconstructional deficits on the pentagon task.
