What Role Does Executive Dysfunction Play In ADHD?

Several prominent theories of ADHD emphasize the importance of higher order cognitive dysfunction, such as working memory difficulties and behavioral disinhibition, as central to ADHD etiology.  It is clear, however, that successful performance on executive function tasks does not solely depend on the higher-order cognitive ability of interest, but also on many non-executive processes (e.g., processing efficiency, motivation).  We are investigating how these more basic processes impact on an individual's performance on executive function tasks to better understand how and to what extent executive function deficits are manifested in children and adolescents with ADHD.  

Why Are Children and Adults With ADHD At Greater Risk Of Obesity?
 

Researchers have tended to investigate the cognitive, academic and social difficulties faced by individuals with ADHD, while their physical health has been less well studied.  Recent evidence suggests, however, that children and adults with ADHD are at greater risk of excessive weight gain, which places them at risk for myriad health problems.  We study common neural and neuropsychological risk factors for both ADHD and obesity, with a view to informing intervention design.

How Does Physical Exercise Impact Cognitive Functioning?

There is a robust literature, primarily in animals and in aging human populations, showing that physical exercise positively impacts brain structure and cognitive performance. Less is known, however, about the impact of physical exercise on the cognitive functioning of young adults and children; this is particularly the case for individuals with ADHD.  We are investigating the acute effects of moderate intensity exercise on young adults' working memory and different aspects of attention.  Furthermore, we are also interested in better understanding the factors that may moderate the relation between exercise and cognitive functioning, such as body mass index, fitness level, ADHD symptom severity, and severity of internalizing problems.

Why Are Children With ADHD At Risk For Learning Problems?

The co-occurrence of a learning disorder in children with ADHD, and of ADHD in children with a learning disorder is around 15-40%, irrespective of whether community or clinical samples are recruited. We investigate why children with inattention may be at greater risk of developing a learning disorder, with a special focus on neuropsychological mechanisms that may explain the ADHD-learning disorder relation.
