“…However, some have suggested that the alternative Color Trails Test is not an equivalent measure[30]. The CERAD WLM task was developed as part of the CERAD protocol for the assessment of dementia and has proven to be a sensitive test for mild impairment as well as dementia[26,31,32]. The 10-item word list has three learning trials and delayed recall is tested after a brief delay.…”

Background Understanding regional differences in cognitive performance is important for interpretation of data from large multinational clinical trials. Methods Data from Durham and Cabarrus Counties in North Carolina, U.S. and Tomsk, Russia (n=2,972) were evaluated. The Montreal Cognitive Assessment (MoCA), Trail Making Test Part B (Trails B), CERAD Word List Memory Test delayed recall (WLM), and self-report ADCS Mail-In Cognitive Function Screening Instrument (MCFSI) were administered at each site. Multilevel modeling measured the variance explained by site and predictors of cognitive performance. Results Site differences accounted for 11% of the variation on the MoCA; 1.6% on Trails B; 1.7% on WLM; and 0.8% in MCFSI scores. Prior memory testing was significantly associated with WLM. Diabetes and stroke were significantly associated with Trails B and MCFSI. Conclusions Sources of variation include cultural differences, health conditions, and exposure to test stimuli. Findings highlight the importance of local norms to interpret test performance.

“…Woodard et al [8] used the Cahn system within a battery of tests and found no difference in CDT scores between MCI and normal participants, but differences were seen between patients with neurocognitive disorder and normal participants. They did not find the CDT to be useful for a brief screening battery [8] .…”

“…However, these battery tests are lengthy and difficult to use as routine in the primary care setting. Therefore, cognitive screening instruments such as the Mini-Mental State Examination (MMSE) [11] are preferable, although the MMSE still takes 20-30 min to administer and can miss patients in the early stages of cognitive impairment [8] . Although the MMSE somewhat reflects visuoconstructive deficits and executive dysfunction, it is mostly recognised as a verbal test [12,13] .…”

Background/Aims: The Clock Drawing Test (CDT) is used in clinical practice for the screening of cognitive disorders. This systematic review aims to present and discuss the CDT scoring methods available in the literature, in order to find differences in administration and utility of the CDT. Methods: A literature search was carried out in Medline (1966 to June 2008), Psychinfo (1967 to June 2008) and EMBASE (1980 to June 2008). Results: All studies showed good interrater and test-retest reliabilities. The correlation with other standard screening tests was statistically significant in most studies, but the results were influenced by age, education and language. In studies that included patients with mild or questionable dementia, the CDT had a low sensitivity and variable specificity. Conclusion: The CDT has the characteristics of a good screening method for moderate and severe dementia. However, the scoring method used and potential confounders need to be taken into consideration.

“…El MMSE es el instrumento más utilizado y validado en el mundo, pero su aplicación requiere de 20 a 30 minutos y no permite detectar demencia en estadios iniciales (12) , debido a su baja sensibilidad para objetivar déficits ejecutivos y déficits leves de memoria y lenguaje (13) . Por otro lado, CAMCOG, DRS y la evaluación neuropsicológica estándar (14) , requieren de personal altamente entrenado y equipamiento especializado.…”

Introducción. La prueba de dibujo del reloj versión de Manos (PDR-M) es un instrumento de evaluación cognitiva breve para la detección de demencia. Objetivos. Evaluar la validez y confiabilidad de la PDR-M para discriminar entre pacientes con demencia y sujetos controles sanos. Materiales y métodos. Se evaluaron sujetos mayores de 65 años de edad, excluyendo los que presentaban enfermedades concomitantes graves y con dificultades auditivas o visuales. Se recogieron datos demográficos y se les realizó PDR-M y Mini Mental State Examination (MMSE). A los individuos del grupo de demencia se les realizó además evaluaciones clínicas, de laboratorio, neuropsicológicas y tomografía cerebral. Se calculó la sensibilidad y especificidad de la PDR-M así como el área bajo la curva ROC. Resultados. Se evaluó 210 individuos, 103 con diagnóstico confirmado de demencia y 107 controles sanos, con edad y sexo similares en ambos grupos; y mayor nivel educativo en el grupo control. Estableciendo un punto de corte de 7 se obtuvo una sensibilidad de 99,0% y una especificidad de 83,5%. Cuando se compararon las áreas bajo la curva ROC de la PDR-M y del MMSE no se encontraron diferencias significativas. Conclusiones. La PDR-M es un instrumento breve y confiable para la detección de demencia en la población urbana de Lima en el Perú. VALIDATION OF THE CLOCK DRAWING TEST -MANOS´ VERSION -AS A SCREENING TEST FOR DETECTION OF DEMENTIA IN OLDER PERSONS OF LIMA; PERU ABSTRACT Introduction. The clock drawing test (PDR-M) -Manos´ version -is a brief cognitive assessment tool for dementia detection.Objectives. To assess the validity and reliability of the PDR-M to discriminate between patients with dementia and healthy control subjects. Materials and methods. We evaluated subjects over 65 years of age, excluding those with severe concomitant diseases and those with hearing or visual impairment. We obtained demographic data and performed the PDR-M and Mini Mental State Examination (MMSE). Subjects of the dementia group were also submitted to clinical, laboratory and neuropsychological evaluations as well as computed tomography scanning. Sensitivity and specificity of the PDR-M were calculated as well as the area under the ROC curve. Results. We evaluated 210 individuals, 103 with confirmed diagnosis of dementia and 107 healthy controls with similar age and sex in both groups, but a higher educational level in the control group. Setting a cutoff point of 7, a sensitivity of 99.0% and a specificity of 83.5% were found. When comparing the areas under the ROC curves of the PDR-M and MMSE we found no statistically significant difference. Conclusions. The PDR-M is a brief and reliable instrument for the detection of dementia in the urban population of Lima, Peru.
