Objectives: The clock drawing test (CDT) is a commonly used cognitive screening test. The purpose of this study was to investigate the effect of selected sociodemographic, clinical and lifestyle factors on the CDT performance in the Polish elderly population. Methods: CDT performance was assessed in 399 elderly subjects randomly selected out of all participants of a nationwide study on aging, PolSenior2, who met the inclusion criteria. CDT was scored using the Manos–Wu method. The short version of the Geriatric Depression Scale (15-item GDS) was used as a mood measuring tool. Results: Our study revealed a significant relationship between CDT performance and age. Multivariate regression analysis demonstrated also that interactions between reading newspapers and gender and between playing games and GDS score were independent predictors of an incorrect CDT. Of note, even though years of education were related to the CDT score (0–10) in the correlation analysis, education did not predict the global CDT score in the regression analysis. Conclusions: Advanced age was related to incorrect CDT performance. Engagement in some leisure activities may predict the CDT score, while global CDT performance, as assessed by the Manos–Wu method, is relatively unaffected by education.

ABSTRACT Introduction: Diagnosing neurocognitive disorders is challenging in low-educated individuals. Objective: To report normative data for the Brief Cognitive Screening Battery (BCSB) and to assess the association of age and education with performance on the BCSB in 240 community-dwelling elderly from Ermelino Matarazzo, São Paulo city. Methods: The inclusion criteria were scoring above the education-adjusted cut-off points on the Mini-Mental State Examination (MMSE) and below six points on the Geriatric Depression Scale (GDS). Results: Age was associated with performance on the Naming, Incidental Memory, Verbal Fluency, Clock Drawing Test, Delayed Recall and Recognition subtests. Education was associated with performance on Naming, Recognition, Verbal Fluency and the Clock Drawing Test. Conclusion: The normative values reported are relevant for diagnosing neurocognitive disorders in low-educated elderly.

ABSTRACT Background: The Clock Drawing Test (CDT) is a brief cognitive screening tool for dementia. Several different presentation formats and scoring methods for the CDT are available in the literature. Objective: In this study we aimed to compare performance on the free-drawn and "incomplete-copy" versions of the CDT using the same short scoring method in Mild Cognitive Impairment (MCI) and dementia patients, and healthy elderly participants. Methods: 90 participants (controlled for age, sex and education) subdivided into control group (n=20), MCI group (n=30) and dementia group (n=40) (Alzheimer's disease - AD=20; Vascular Dementia - VD=20) were recruited for this study. The participants performed the two CDT versions at different times and a blinded neuropsychologist scored the CDTs using the same scoring system. Results: The scores on the free-drawn version were significantly lower than the incomplete-copy version for all groups. The dementia group had significantly lower scores on the incomplete-copy version of the CDT than the control group. MCI patients did not differ significantly from the dementia or control groups. Performance on the free-drawn copy differed significantly among all groups. Conclusion: The free-drawn CDT version is more cognitively demanding and sensitive for detecting mild/early cognitive impairment. Further evaluation of the diagnostic value (accuracy) of the free-drawn CDT in Brazilian MCI patients is needed.

To evaluate the predictability of progression of cognitive impairment to dementia using qualitative clock drawing test (CDT) scores, we administered both the CDT using Cahn et al.’s qualitative scoring system and the Mini-Mental State Examination (MMSE) to assess cognitive function in non-demented older individuals attending a memory clinic at a university hospital. Patients visiting the clinic for assessment of cognitive function between January 2015 and December 2019 were enrolled, and only those who were diagnosed as not having dementia at the time of initial assessment completed a follow-up assessment at 1 y (n = 163). To examine any association of qualitative CDT score with progression to dementia, multiple logistic regression analysis was conducted with the change in diagnosis from non-dementia to dementia at 1 y as the dependent variable. A total of 26 participants (16.0%) were diagnosed as having converted to dementia. Multiple logistic regression analysis revealed that both the qualitative CDT score using Cahn et al.’s scoring system and the existence of conceptual deficits were significantly associated with progression to dementia at 1 y after initial assessment of cognitive function, irrespective of the MMSE score, among non-demented older individuals. The CDT may be a useful predictor of progression to dementia in primary care settings.

ABSTRACTBackground:The clock drawing test (CDT) is a common and widely used cognitive screening instrument for the diagnosis of dementia. However, it has remained unclear whether it is a suitable method to identify mild cognitive impairment (MCI). The aim of this paper is to review systematically the studies concerning the utility of the CDT in diagnosing MCI.Method:A systematic literature search was conducted. All studies dealing with utility of CDT in diagnosing MCI regardless of the applied CDT scoring system and MCI concept were selected.Results:Nine relevant studies were identified. The majority of the studies compared average CDT scores of cognitively healthy and mildly impaired subjects, and four of them identified significant mean differences. If reported, sensitivity and specificity have been mostly unsatisfactory.Conclusion:CDT should not be used for MCI-screening.

Cognitive Screening Measure

The Clock Drawing Test (CDT) has a known potential for the detection of cognitive impairment in populations with dementia, especially Alzheimer disease (AD). Our aim was to compare the clinical utility of 3 CDT scoring systems (Rouleau, Cahn, and Babins) in several pathologies with cognitive compromise from a tertiary center memory clinic. We selected patients with a clinical diagnosis of mild stage AD, behavioral variant frontotemporal dementia (FTD), vascular dementia (VaD), dementia with Lewy bodies (DLB), and Parkinson disease with dementia (PDD). The results showed significant differences between the several diagnoses with the following pattern of results: AD, DLB < FTD, VaD, PDD. Qualitative analysis of clock drawing errors confirmed the stimulus-bound response as a hallmark of AD, while conceptual deficit was significantly more prevalent in patients with AD and DLB. Our results supported the CDT potential as a cognitive screening measure for mild dementia, particularly sensitive to AD and DLB, especially when we used the Cahn scoring system and its analysis of qualitative errors.
