Attention-Deficit/Hyperactivity Disorder (ADHD) is the most common neurodevelopmental disorder in children that shows comorbidity with several psychopathology included stuttering. The prefrontal cortex is the area of brain that sends and receives projections from virtually all cortical sensory systems, motor systems, and many subcortical structures. It has been shown that psychostimulant medica...

conclusions the results may help clinicians for early intervention and focus on related components of executive function to improve the educational performance of dcd children. knowing that executive function skills are associated with these two achievement domains suggests potentiality of targeted math and spelling interventions for dcd children. results the findings showed that components of ...

The executive functions of human working memory have recently become a common target of investigation, mainly in neuroimaging and patient studies. Those studies have indicated that executive functions are (a) strongly related to the functions of the prefrontal structures, and (b) are required whenever the task reaches a certain level of complexity. However, numerous attempts to operationally de...

specialized systems—each handling specific kinds of information, working relatively independently of each other to do routine tasks. When presented with a new task, however, these systems need to develop a responsive program. this process of defining the task, and designing a program to respond, is part of the brain’s executive functions, which are believed to be mostly located in the anterior ...

The aim of this study was to investigate the relationship among childhood trauma, executive impairments, and altered resting-state brain function in young healthy adults. Twenty four subjects with childhood trauma and 24 age- and gender-matched subjects without childhood trauma were recruited. Executive function was assessed by a series of validated test procedures. Localized brain activity was...

OBJECTIVES Cerebral white matter hyperintensities (WMHs) on magnetic resonance imaging (MRI) are a recognised risk factor for post-stroke dementia. Their specific relations to cognitive impairment are still not well known. The purpose of this study was to explore how the severity and location of WMHs predict neuropsychological test performance in the context of other brain lesions in elderly st...

Recently, research on attention has focused on 3 networks that are linked to separate brain regions, i.e. orienting, alerting, and executive control. The attention network test (ANT) is one of the methods to measure the three attention functions. However, neuropsychological investigations have not examined the anatomical disassociation of different attention networks with the same task. We comp...
