Which quick visuospatial screening task is commonly used in the mental status exam?

• A. Clock-drawing test
• B. Digit span
• C. Serial 7s
• D. Mini-Mental State Examination

Answer: (A)

Visuospatial function is quickly screened with a task that requires perceiving spatial relationships and planning a drawing. The clock-drawing task asks the patient to draw a clock face, place the numbers accurately, and set the hands to a given time. This simple activity probes visuoconstructional abilities and planning, which rely on parietal and frontal networks, making it sensitive to cognitive impairment. It is fast to administer, typically completed in a couple of minutes, and widely used in the mental status exam as a quick check of visuospatial function. The other options assess different domains: digit span tests attention and working memory; serial 7s assesses attention and calculation; the Mini-Mental State Examination is a broader global screen that covers multiple domains but is not specifically a quick visuospatial construction task. So the clock-drawing test is the best choice for a brief visuospatial screen.
