Summary
ADHD is the most common childhood developmental disorder, characterised by inattentive and/or hyperactive behaviours. Cognitive control has been highlighted as a potential mediator of ADHD symptoms. This program will i) delineate the relationship between cognitive control and ADHD symptoms, ii) develop a cognitive training intervention to target the underlying mechanisms identified as mediators of ADHD symptoms and iii) evaluate the program in a gold-standard clinical trial.
Developing A Pathophysiological Model For Attention Deficit Hyperactivity Disorder: A Path To Biomarker Discovery

Summary
Despite the efficacy of stimulant medication in treating attention deficit hyperactivity disorder (ADHD), we lack mechanistic accounts of the neuropathology of ADHD. A major barrier is the lack of human disease models representing clinical symptoms. The derivation of a novel, cell-based ADHD model proposed in this project will shed new light on the physiological bases of ADHD and be a rich resource for biomarker discovery
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.
Cellular Modelling Of Attention Deficit Hyperactivity Disorder (ADHD) Risk Genes

Summary
Attention deficit hyperactivity disorder is a prevalent behavioural disorder affecting 7.4% of Australian children and adolescents. It has a strong genetic component with high heritability estimates (75–90%) comparable to other serious mental illness such as autism and schizophrenia. Identification and functional characterization of the genetic causes of this disorder will enhance our knowledge of its neurobiology and revolutionise the drug treatment of the disorder.
Improving Outcomes For Children With ADHD: Mapping Developmental Trajectories And Developing Targeted Interventions

Summary
Attention deficit hyperactivity disorder (ADHD) is one of the most common mental health disorders affecting young people in Australia. My research program aims to generate new knowledge to inform clinical practice for children with ADHD including: 1) long-term outcomes and key predictors of outcomes; and 2) novel treatments to improve the lives of children and families. Growth of my research program is feasible and underpinned by existing platforms including numerous NHMRC-funded studies.
Does The Treatment Of Anxiety In Children With ADHD Improve Outcomes? A Large-scale Randomised Controlled Trial
Funder
National Health and Medical Research Council
Funding Amount
$854,630.00
Summary
Attention deficit hyperactivity disorder (ADHD) affects 5% of Australian children. Up to 64% of children with ADHD experience impairing anxiety, which is associated with higher levels of ADHD symptoms and poorer quality of life. This randomised controlled trial will determine whether treating anxiety in children with ADHD improves outcomes.
Towards An Evidence-based And Equitable Mental Health System For Children In Australia

Funding Amount
$706,059.00
Summary
Mental health problems in Australian children are common and associated with adverse short and long term outcomes. Treatments including medication and psychological interventions can improve these outcomes but only 50% of Australian children with mental health problems receive them. We will quantify child, family, clinician and health care system factors associated with treatment use and provide a roadmap for clinicians and policy makers to improve access for Australian children.
Impact Of A Sleep Intervention In ADHD: Translational Randomised Trial

Funding Amount
$1,020,595.00
Summary
Up to 50% of children with ADHD experience sleep problems which worsen their ADHD symptoms, behaviour, quality of life and day to day functioning. In a previous trial, we showed that treating sleep problems in children with ADHD improves these outcomes. We now want to know if these benefits can be replicated when general paediatrcians and psychologists deliver the same sleep intervention in community settings.
A Dimensional Approach To Mapping The Risk Mechanisms Of Mental Illness

National Health and Medical Research Council
Funding Amount
$1,677,975.00
Summary
There is ongoing debate about whether current definitions of mental disorders are accurate. We will use statistical techniques to identify the core dimensions of liability for mental illness, and map how genes and brain organization drive differences between people along each dimension.
Trajectories In Brain Structure And Function For Children With And Without ADHD: Associations With Academic, Cognitive, Social, And Mental Health Outcomes

Funding Amount
$1,235,951.00
Summary
Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most common disorders of childhood, affecting 7% of school-age children. This project will use neuroimaging to describe how brain structure and function change across late childhood to early adolescence for children with and without ADHD, and how those changes reflect ADHD symptom severity and functional outcomes (academic, cognitive, social, and mental health).
