Summary
This study establishes normal clock drawing test values in healthy older adults, finding no correlation with age, sex, or education. The test demonstrated high inter-examiner reliability for cognitive function assessment.
Area of Science:
- Neuropsychology
- Gerontology
Context:
- The clock drawing test (CDT) is a widely used screening tool for cognitive impairment.
- Establishing normative data is crucial for accurate interpretation of CDT performance in diverse populations.
Purpose:
- To determine the normal values of the clock drawing test (CDT) in a sample of 58 healthy elderly individuals.
- To evaluate the CDT's utility as a neuropsychological parameter for assessing cognitive functions in older adults.
Summary:
- Quantitative parameters of the CDT were assessed using 'on command' and 'on copying' tasks.
- Average scores were 8.04 (SD 1.60) for 'on command' and 9.20 (SD 0.93) for 'on copying'.
- No significant interaction was found between CDT scores and demographic parameters (age, sex, educational level).
Impact:
- The findings provide normative data for the CDT in healthy older adults.
- The study confirms the high inter-examiner reliability of the CDT, supporting its use in clinical settings.
- This research aids in the accurate neuropsychological evaluation of cognitive functions in the elderly population.
