Aims. The realization of an experimental set-up for the quantitative and objective description of drawing using optoelectronic systems, which could be used when a quantification of the realization of specific drawing tests is required. Methods. Healthy subjects, subjects with Parkinson's Disease and subjects with Parkinson's Disease and Dementia were evaluated by the Mini Mental Scale Evaluatio...

Background Screening tests have been used for cognitive deficits in Parkinson's disease (PD). Objective This study compared the Montreal Cognitive Assessment (MoCA) test, the Mini-Mental State Examination (MMSE) and the clock drawing test for this purpose. Methods A total of 50 patients with PD were selected, 41 (82%) were diagnosed with dementia by the criteria of the Movement Disorder Soc...

OBJECTIVES To examine the reliability and validity of the Clock Drawing Test when used as a cognitive screening instrument for mild to moderate dementia, and to compare different scoring mechanisms. DESIGN Retrospective analysis of clock drawing performance using three published scoring methods (Shulman, Sunderland and Wolf-Klein). SETTING Hospital-based memory disorders clinic. PARTICIPA...

OBJECTIVES To assess the usefulness, relative ease of administration, and patient acceptance of the clock drawing test as well as the time and change test for detecting dementia in Chinese elderly adults. DESIGN Prospective case-controlled study. SETTING Memory clinic and geriatric clinic of a district hospital, Hong Kong. PARTICIPANTS A convenient sample of 85 subjects aged 65 years or o...

The clock drawing test has been found to be sensitive to visual-spatial perception, graphomotor skills, verbal reasoning, and executive functioning in adult patient populations, as well as frontal lobe maturation in normal children. Our study is among the first to assess the use of clock drawing as a neuropsychological measure in the pediatric population. Participants included 41 children with ...

Clock drawing is a quick, easy to remember test that is well received by patients. It is a good screening test for Alzheimer's disease in the outpatient setting. We evaluated its usefulness compared with the standard Mini Mental State Examination (MMSE) in elderly acute medical and surgical hospital admissions. Within 48 hours of admission, 117 patients over 70 years old were administered the M...
