The Clock Drawing Test is a brief cognitive screening task that evaluates visuospatial organization, executive planning, and conceptual understanding of time. It is often used as a quick adjunct to memory screens in geriatrics, primary care, and neurology assessments.
Formula: Simplified 4-point rubric: circle + numbers + hand placement + target time representation.
Abnormal clock drawings suggest possible cognitive impairment and support further structured assessment.
Use as a rapid screening adjunct when cognitive concerns are raised in older adults or medically complex patients.
Performance may be affected by vision, education, language, motor limitations, and scoring-method variability.
