Summary
My project will investigate how connections in the brain change during the transition from childhood to adolescence. Advanced neuroimaging techniques will be used to understand how different parts of the brain are connected to one another, and how this changes over time. I will examine typically developing children, as well as those with attention deficit hyperactivity disorder (ADHD) in order to understand how neuropsychiatric disorders affect brain development.
Genetic Influences On The Comorbidity Between Attention Deficit Hyperactivity Disorder And Substance Use

Summary
Substance use (SU) problems are more common among individuals with a history of ADHD. However, the reasons for this relationship are unclear. Our study will examine the extent to which this relationship is due to shared genetic influences using data collected during interviews about ADHD and SU in a large sample of young adult twins, their siblings and their parents. The results will aid in developing treatments targeting the symptoms of ADHD and SU concurrently.
The Genetics Of Cognitive Deficits In Attention Deficit Hyperactivity Disorder (ADHD)

Summary
Attention deficit hyperactivity disorder (ADHD) is a common psychiatric disorder of childhood that is marked by age-inappropriate levels of inattention and-or hyperactivity-impulsivity. The disorder appears genetic with a number of different genes likely contributing risk for ADHD. This project takes an innovative approach by asking whether there are different genetic profiles associated with children with ADHD who do or do not have neurocognitive deficits.
ADHD Grown-up: Genetic And Environmental Determinants Of The Adult Outcomes Of Childhood ADHD And Comorbid Conditions

Summary
ADHD remains a controversial issue especially in adulthood. There are many related behavioural problems including substance abuse, anxiety, depression, and personality disorders. Australia is such a focus for twin research that many twin families have taken part in several studies of different aspects of mental health over the years. This grant allows us to link the various datasets to create a unique longitudinal genetic resource and to examine the longterm outcomes.
Frontal-striatal-parietal Activation In Children With ADHD, Combined Type: A Functional Magnetic Resonance Imaging Study

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

Goal-directed Behaviour In Adolescent ADHD: Neural Connectivity And It’s Significance For Clinical Translation

Funding Amount

Summary
Impaired goal-directed decision-making leads to significant difficulties in adolescent attention deficit hyperactivity disorder (ADHD). This research will use novel imaging techniques to study individual-level impairments in brain connectivity in decision making circuits and the effects of common ADHD medications. As these medications are currently prescribed by trial and error, identifying specific connectivity brain signatures will make major contributions to personalised treatment selection.
Attention deficit hyperactivity disorde(ADHD) is the most prevalent mental disorder of childhood affecting around 7.5% of Australian school age children. The disorder is strongly genetic and causes significant impairments in academic functioning, family and peer relations with sufferers at increased risk for drug abuse. Identification and characterisation of rare mutations will enhance our knowledge of the neurobiology and advance the search for next generation drug treatments for the disorder.
The LAPSE Study: Impact Of Local Sleep In The ADHD Brain

Summary
Attention Deficit and Hyperactivity Disorder (ADHD) is characterised by inappropriate levels of inattention. ADHD patients also frequently experience sleep disturbances and abnormal daytime sleepiness. We will examine to what extent sleep disturbances can account for ADHD symptoms by examining if the attentional deficits associated with ADHD can be explained by a phenomenon called local sleep, whereby parts of the brain spontaneously fall asleep in the context of a globally awake brain.
Melatonin For Initial Insomnia In Stimulant-treated Pediatric ADHD

Funding Amount
$590,373.00
Summary
Does melatonin work for children with ADHD and initial insomnia? We will study children with ADHD and initial insomnia using N-of-1 trials. This is a trial in a single person, which allows them the opportunity to learn if melatonin is effective for them.We will compare the usual clinical trials (RCTs, which do not give individual results) with combined results from all the 270 patients who have done N-of-1 trials. Data from the first part of each person’s n-of-1 trial will form the RCT.
