Introduction. The symptoms that comprise inattentive behaviour in ADHD include problems with focusing on a task and sustaining attention over a long period, even in advantageous external conditions. There is also a characteristic excessive distractibility under the influence of other, unimportant stimuli. Thus attention processes are one of the main variables which form the clinical picture of ...

This study examined the hypothesis that individuals with attention deficit hyperac‐ tivity disorder, predominantly inattentive type (ADHD-I), show both executive function (EF) deficits and non-EF deficits. A group with ADHD-I (n = 16) and a paired control group (n = 21) completed a battery of tasks covering the major domains of EF (planning, working memory, flexibility and inhibition) and non-E...

OBJECTIVE Research on the long-term sequelae of treatment for pediatric brain tumors has identified significant neurocognitive deficits experienced by many survivors. Despite indications of deficits based on cognitive assessment, the identification of specific neurobiological mechanisms of these deficits using neuroimaging techniques has yet to be considered. METHOD This study used norm-refer...

BACKGROUND Although intellectual and neurocognitive deficits accompany schizophrenia, there are inconsistencies in the literature concerning issues of intellectual decline, premorbid deficits, a modal deficit pattern, and preserved abilities. METHODS A battery of neuropsychological tests was administered once to 117 consecutively admitted patients with chronic schizophrenia and a group of 27 ...

A great deal of research has been directed toward understanding the general principles that govern attention. More specifically, research has sought to define the multidimensional nature of attention, the neuroanatomical system responsible for attention, and the ways in which attention can be operationally defined and measured. In addition to these investigations on attention in general, there ...

This study assesses attention and response control through visual and auditory stimuli in a primary care pediatric sample. The sample consisted of 191 participants aged between 7 and 13 years old. It was divided into 2 groups: (a) 90 children with ADHD, according to diagnostic (DSM-IV-TR) (APA, 2002) and clinical (ADHD Rating Scale-IV) (DuPaul, Power, Anastopoulos, & Reid, 1998) criteria, and (...

Stimulant-associated growth deficits in children with attention deficit hyperactivity disorder (ADHD) have long been a concern. Height deficits in preadolescence have been reported, but adult heights have been reported to be uncompromised. It is possible that the catch-up growth that occurs is related to ADHD-associated delayed maturation and not to the cessation of stimulant treatment. To date...

CONTEXT A lack of inhibitory control has been suggested to be the core deficit in attention-deficit/hyperactivity disorder (ADHD), especially in adults. This means that a primary deficit in inhibition mediates a cascade of secondary deficits in other executive functions, such as attention. Impaired stopping has been claimed to support the inhibition hypothesis. However, executive functions such...
