Which test screens visuospatial and executive function?

• A. Clock drawing test
• B. Mini Mental State Examination
• C. Mini-Cog
• D. Montreal Cognitive Assessment

Answer: (A)

Visuospatial ability and executive function are best assessed with a task that requires planning and spatial organization. The Clock Drawing Test asks the patient to draw a clock face with all the numbers and set to a specified time. To do this, they must understand the instruction, place the numbers in the correct spatial positions, and arrange the hands to show the requested time. This directly taps both how the person perceives spatial relationships and how they plan and execute a sequence of actions, which are core elements of visuospatial processing and executive function. Because of its focused demand on those abilities and its rapid administration, it’s a widely used quick screen for detecting visuospatial deficits and executive dysfunction, such as seen in early dementia or other neurologic conditions.

The other options involve broader cognitive screening: the Mini-Mental State Examination covers several domains but is less sensitive to isolated executive dysfunction; the Mini-Cog includes a clock drawing portion but combines it with memory recall, diluting the pure screen of visuospatial/executive skills; the Montreal Cognitive Assessment includes multiple visuospatial and executive tasks but is longer and broader in scope than the single, targeted clock drawing task.
