Which two drawing tasks in the MoCA assess visuospatial abilities?
Answer: Cube copy and clock drawing
The MoCA visuospatial section includes a three-dimensional cube copy task and a clock drawing task, both of which require spatial processing and constructional ability.
On the MoCA cube copy task, what features must the copied cube demonstrate to earn 1 point?
Answer: It must be three-dimensional with parallel lines of approximately equal length
The cube copy earns 1 point if it is three-dimensional, has all parallel lines roughly parallel, and all sides are roughly equal in proportion. A flat two-dimensional square does not receive credit.
Which domain does the clock drawing fall under on the MoCA form?
Answer: Visuospatial/Executive
Clock drawing is categorized under the Visuospatial/Executive domain on the MoCA because it requires both spatial construction and executive planning.
What does poor performance on the MoCA cube copy task most directly indicate?
Answer: Visuoconstructional impairment, suggesting parietal lobe dysfunction
Difficulty reproducing the three-dimensional cube reflects visuoconstructional impairment, often associated with parietal lobe dysfunction, and is seen in Alzheimer's disease, Lewy body dementia, and cortical posterior disorders.
A patient copies the cube but draws it as a flat square with lines attached. This copy earns:
Answer: 0 points — the copy is not three-dimensional
A flat two-dimensional representation of a cube does not meet the requirement for a three-dimensional copy. It scores 0 on the cube copy task.
Why does the MoCA assess visuospatial abilities rather than limiting testing to verbal and memory tasks?
Answer: Because visuospatial deficits are prominent in several dementia subtypes
Visuospatial deficits are prominent features of Alzheimer's disease, Lewy body dementia, and posterior cortical atrophy. Including visuospatial tasks increases the sensitivity of the MoCA for detecting these specific dementia subtypes.
