Attention Deficit Hyperactivity Disorder (ADHD) is the most common neurobehavioural disorder of childhood. Although graphomotor deficits are not listed as a diagnostic criterion for ADHD, they are very common. It remains unclear, however, whether this is caused by motor deficits or by problems in planning and organizing behavior. The experimental group consisted of 30 boys with ADHD. The contro...

BACKGROUND Leukoaraiosis, microbleeds, and silent brain infarctions are phenotypes of small vessel disease. Leukoaraiosis is the most prevalent, and advanced periventricular leukoaraiosis is regarded as a strong predictor of cognitive dysfunction. Microbleeds and silent brain infarctions sometimes coexist with leukoaraiosis. This study aims to analyze the effects of microbleeds and silent brain...

Objective To describe and analyze cognitive aspects in patients with chronic pain and a control group without pain. Method A case-control study was conducted on 45 patients with chronic pain and on 45 control subjects. Data including pain diagnosis, comorbidities and medication used, were evaluated. Cognitive tests, such as the Montreal Cognitive Assessment (MoCA), Verbal Fluency Test, Clock Dr...

Young children are devoting more and more time to playing on handheld touchscreen devices (e.g., iPads). Though thousands of touchscreen apps are claimed to be "educational," there is a lack of sufficient evidence examining the impact of touchscreens on children's learning outcomes. In the present study, the two questions we focused on were (a) whether using a touchscreen was helpful in teachin...

The clock drawing test has been routinely administered by many neuropsychologists as part of their testing battery with the adult population. Our study investigated the development of clock face drawing in normal children ages 6 to 12 years. Conceptualization of time and construction of the clock face were assessed by an adapted scoring system developed as part of the investigation. As a group,...

Objective: Mini-mental state examination, a nonspecific measure of global cognitive function, and the clock drawing test, a very concise and specific measure of cognitive function, are among the most widely used screening tests for cognitive dysfunction. The present research aimed to examine the correspondence between MMSE and CDT scores. Methods: A total of 70 older adults (mean(SD) age=69.70...

BACKGROUND Many scoring systems exist for clock drawing task variants. However, none of them are reliable in evaluating longitudinal changes of cognitive function. The purpose of this study is to create a simple yet optimal scoring procedure to evaluate cognitive decline using a clinic-based sample. METHODS Clock-drawings from 121 participants (76 individuals with no dementia and later did no...
