MMSE Visuoconstructional Skills 5

Question 1

A patient scores 0 on the pentagon task but achieves 28/29 on all other MMSE items. Which additional test would BEST clarify the nature of the visuoconstructional deficit?

Accepted Answer

Rey-Osterrieth Complex Figure Test

Answer

The Rey-Osterrieth Complex Figure Test provides detailed analysis of visuoconstructional and visuospatial memory that far exceeds the single MMSE item.

Question 2

In what way does the MMSE pentagon task test 'construction' as opposed to purely 'perception'?

Accepted Answer

It requires physical reproduction of the figure, not just recognizing it

Answer

Construction requires the patient to actively reproduce the figure using hand movements, integrating visual input with motor output rather than passively perceiving the image.

Question 3

Which scoring criterion is explicitly NOT required for the MMSE pentagon copy to receive full credit?

Accepted Answer

The figures must be approximately the same size as the model

Answer

Size matching is not a scoring criterion; only angle count (five per pentagon) and a four-sided intersection region are required for credit.

Question 4

A right-handed patient has a right hemisphere stroke. How would this most likely affect performance on the pentagon copy task?

Accepted Answer

Significant impairment, because the right hemisphere dominates visuospatial processing

Answer

The right hemisphere is dominant for visuospatial and constructional abilities; right hemisphere stroke commonly causes severe difficulty with figure copying.

Question 5

Which of the following findings on the pentagon copy is an example of 'closing-in' phenomenon, associated with Alzheimer's disease?

Accepted Answer

Drawing the copy directly on top of or immediately adjacent to the printed model

Answer

Closing-in is a recognized error pattern in Alzheimer's disease where patients draw their copy overlapping or immediately adjacent to the stimulus figure.
