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.
Thalamocortical Neural Circuits In Higher Order Cognitive And Sensory Processing

Summary
Schizophrenia, depression and dementia are devastating disorders with problems in thinking and sensory perception, but the neural circuits causing these symptoms are not known. I will use new optical and genetic tools in mice to identify the cortical and subcortical circuits required for complex touchscreen tasks, the same tasks to assess patients. Identification of neural circuits that underlie clinical symptoms will increase our understanding of these disorders and improve treatments.
Interactive Attention Training Technology To Enhance Cognitive Skills In Early Life

Summary
Over 30,000 Australian children enter school with attention difficulties each year. We have established a suite of tasks to train attention based on over 20 years of research into neurodevelopmental disorders and attention. These are delivered on tablets in the form of a game known as TALI Train. We now aim to show TALI can improve attention in children with acquired brain injuries and typically developing children for commercialisation to a broad market.
A Study Addressing Motor, Cognitive And Attentional Deficits In Presymptomatic Gene Carriers For Huntington's Disease

Summary
Since the discovery of the Huntington's disease (HD) gene mutation there has been much controversy in the literature relating to whether there are any preclinical deficits in individuals who are gene positive for HD but who have not yet been clinically diagnosed with the disease. Our aim is to examine, over a three year period, the cognitive, attentional and motor performance of presymptomatic gene-positive, and negative, individuals on a wide variety of computerized experimental procedures, whi ....Since the discovery of the Huntington's disease (HD) gene mutation there has been much controversy in the literature relating to whether there are any preclinical deficits in individuals who are gene positive for HD but who have not yet been clinically diagnosed with the disease. Our aim is to examine, over a three year period, the cognitive, attentional and motor performance of presymptomatic gene-positive, and negative, individuals on a wide variety of computerized experimental procedures, which we have previously shown to be sensitive to deficits in individuals who have already been diagnosed with HD. If progressive behavioural changes in gene-positive individuals can be reliably documented to occur before the clinical symptoms of HD are evident, this would be of profound significance as it would allow a set of criteria to be established to assist in early detection of clinical onset of symptoms, and possibly permit use of newly-emerging therapies.Read moreRead less
Impact Of A Sleep Intervention In Children With ADHD: A Randomised Controlled Trial

Funding Amount
$384,230.00
Summary
Attention deficit hyperactivity disorder (ADHD) affects up to 7.5% of Australian children. Between 50 and 70% of parents also report sleep problems (eg night waking, insomnia) in their child with ADHD. Such sleep problems are associated with poorer child behaviour, concentration, and school attendance as well as poorer parent mental health and work attendance. This randomised controlled trial will determine whether treating sleep problems in children with ADHD can improve these outcomes.
Ascending Control Of Behavioural State And Cognition - Role Of Nucleus Incertus And Relaxin-3 Transmission

Summary
Mental illness and dementia are significant social and economic burdens worldwide and knowledge of their underlying causes and more effective therapies are required. Our research aims to use pre-clinical models to characterize a little studied neuronal network implicated in control of brain theta rhythm activity, which could lead to improved treatment of neuropsychiatric diseases such as anxiety and depression, and degenerative cognitive decline.
Investigating A Theoretical Model Of Cognitive Control In Children With Attention Deficit Hyperactivity Disorder (ADHD): Informing Our Approach To Cognitive Training.

Funding Amount

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
Cellular Modelling Of Attention Deficit Hyperactivity Disorder (ADHD) Risk Genes

Funding Amount

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.
