Summary
Attention Deficit Hyperactivity Disorder, combined type (ADHD-CT) is a common neuropsychiatric disorder that has serious consequences for affected children's educational and social development and success in later life. Despite a large investment in research investigating aetiology and therapeutic strategies that arise from these aetiological investigations, ADHD-CT remains poorly understood and it is often viewed with therapeutic pessimism.

Despite a large investment in research investigating aetiology and therapeutic strategies that arise from these aetiological investigations, ADHD-CT remains poorly understood and it is often viewed with therapeutic pessimism. Understanding the neurobiological basis of ADHD-CT is of tremendous importance for the development of more specific and targeted medication and-or psychological treatments and, ultimately, to obtain the best clinical outcome for individual children with ADHD-CT. We have previously examined the function of frontal-striatal-parietal brain networks in adolescent boys with ADHD-CT, showing dysfunction of brain systems important for the control of visuospatial attention. In this project, we aim to examine whether these changes in frontal-striatal-parietal brain function also occur in pre-pubertal 8-12 year-old boys with ADHD-CT. This is important for two major reasons: Firstly, adolescents and young adults examined in previous brain imaging studies of ADHD-CT, including our own, are not truly representative of the core of the disorder, as ADHD-CT has its peak prevalence from 8 to 12 years of age. Secondly, by now comparing pre-pubertal ADHD-CT and healthy control children we can determine whether the changes in brain function we have previously identified represent developmental stage independent brain dysfunction that is characteristic of ADHD-CT.Read moreRead less
