Cognitive measures are used frequently in the assessment and diagnosis of attention-deficit/hyperactivity disorder (ADHD). In this meta-analytic review, the authors sought to examine the magnitude of differences between ADHD and healthy participants on several commonly used intellectual and neuropsychological measures. Effect sizes for overall intellectual ability (Full Scale IQ; FSIQ) were significantly different between ADHD and healthy participants (weighted d =.61). Effect sizes for FSIQ…

Neuropsychological functioning in children with ADHD: Symptom persistence is linked to poorer performance on measures of executive and nonexecutive function

The present study compared the current intellectual and neuropsychological functioning of 55 children diagnosed with attention deficit hyperactivity disorder (ADHD group) 4 years earlier with that of

Utility of cognitive neuropsychological assessment in attention-deficit/hyperactivity disorder

The present review addresses the question of whether and how neuropsychological tests assessing cognition in attention-deficit/hyperactivity disorder (ADHD) can contribute to clinical and scientific

Executive functioning among Finnish adolescents with attention-deficit/hyperactivity disorder.

Cognitive functioning in a population sample of adolescents with and without attention-deficit/hyperactivity disorder from the Northern Finland Birth Cohort 1986 is examined, indicating that EFDs are more frequent in ADHD than control or behavior disorder groups.

Neuropsychological functioning in girls with attention-deficit/hyperactivity disorder with and without learning disabilities.

The authors' goal was to assess neuropsychological performance in girls with attention-deficit/hyperactivity disorder (ADHD) and evaluate the role of comorbid learning disabilities (LDs).

Assessment of executive function in ADHD adolescents: contribution of performance tests and rating scales

The results suggest that the combined use of performance-based tests and rating scales provides valuable complementary information that can improve the assessment of executive domains in ADHD.

The evidence suggests that ADHD is associated with substantial deficits across a variety of neurocognitive domains.

The Role of Neurocognitive Tests in the Assessment of Adult Attention-Deficit/Hyperactivity Disorder

Results indicated that measures of working memory, sustained attention, response speed, and variability best discriminated ADHD and non-ADHD participants and suggest that neuropsychological test measures used in conjunction with other clinical assessments may enhance prediction of adult ADHD diagnoses.



Learning disabilities and executive dysfunction in boys with attention-deficit/hyperactivity disorder.

Data indicate that comorbid LD, especially arithmetic disability, significantly increases the severity of executive function impairment in ADHD.

A Comparison of the Neuropsychological Profiles of the DSM-IV Subtypes of ADHD

The results do not support distinct neuropsychological deficits in ADHD-IA and ADHD-C children, and suggest that symptoms of inattention, rather than symptoms of hyperactivity/impulsivity, are associated with neuroPsychological impairment.

Neuropsychological Characteristics of Adults with ADHD: A Comprehensive Review of Initial Studies

A review of the literature indicates that adults with ADHD demonstrate subtle impairments on select measures of attention and executive functions, auditory-verbal list learning, and complex information processing speed relative to normal controls.

Executive functioning and olfactory identification in young adults with attention deficit-hyperactivity disorder.

Executive function deficits found in childhood ADHD exist in young adults with ADHD and are largely not influenced by comorbidity but may be partly a function of low intelligence.

Time perception and reproduction in young adults with attention deficit hyperactivity disorder.

Findings on time perception in ADHD children to adults were extended to adults and ruled out comorbidity as the basis of the errors.

Comprehensive evaluation of attention deficit disorder with and without hyperactivity as defined by research criteria.

Results indicate that these 2 types of ADD may be separate, distinct childhood disorders rather than subtypes of a common attention deficit.

Responsiveness of children with attention deficit-hyperactivity disorder to reward and response cost: differential impact on performance and motivation.

For ADHD children, motivational effects appeared to be influenced by self-perceptions of performance, and response cost showed stronger effects but at the expense of decreased self-rated motivation on the low-interest task.

A theoretical model that links inhibition to 4 executive neuropsychological functions that appear to depend on it for their effective execution is constructed and finds it to be strongest for deficits in behavioral inhibition, working memory, regulation of motivation, and motor control in those with ADHD.
