BACKGROUND Executive cognitive dysfunction can precede the memory disturbances of dementia. People with executive cognitive dysfunction can have a normal Mini-Mental State Examination (MMSE) score but still have severe functional limitations. We evaluated the usefulness of clock drawing in identifying people with executive dysfunction who have a normal MMSE score. METHODS We reviewed the char...

BACKGROUND AND AIM Depressive pseudodementia (DPD) is a condition which may develop secondary to depression. The aim of this study was to contribute to the differential diagnosis between Alzheimer disease (AD) and DPD by comparing the neurocognitive tests and hippocampal volume. MATERIALS AND METHODS Patients who met criteria of AD/DPD were enrolled in the study. All patients were assessed us...

BACKGROUND/AIM Post-stroke cognitive impairment and dementia may be caused by pure vascular, pure degenerative or mixed disease. The relation between post-stroke cognitive impairment and the combination of vascular pathology and degenerative changes is less evaluated. We aimed to evaluate the associations between white matter lesions (WMLs) and patient performance 1 year after stroke on tests o...

OBJECTIVE To determine the accuracy of the Mini-Mental State Examination combined with the Verbal Fluency Test and Clock Drawing Test for the identification of patients with mild cognitive impairment and Alzheimer's disease (AD). METHOD These tests were used to evaluate cognitive function in 247 older adults. Subjects were divided into three groups according to their cognitive state: mild cog...

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 ...

BACKGROUND Drawing, and the clock drawing task in particular, is widely used as a diagnostic tool in the study of hemispatial neglect. It is generally assumed that the errors in graphic production, such as the misplacement of numbers, reflect a visuospatial deficit, and that drawing production itself (for example, producing the circle) is unimpaired. OBJECTIVES To test this assumption by exam...

Background Previous studies suggest the usefulness of CDT in distinguishing between neurodegenerative diseases. The purpose this study was to examine differences performance individuals with AD and PD compared normal controls. Methods Total 194 participants. Four groups included analysis: patients that met diagnostic criteria for late MCI/mild AD, moderate no cognitive impairment, All participa...

Abstract Alzheimer’s disease and related dementias, a leading cause of disability among older adults, has become critical public health concern. The clock-drawing test (CDT), which asks subjects to draw clock, typically with hands showing 11:10, been widely used as screening tool detect dementia in clinical research surveys. clock-drawings are often coded into binary (e.g., normal vs. abnormal)...
