Summary
Severe Cannabis Use Disorders cause significant harms to quality of life and outcomes including mental health, cognition, motivation and general well being. We will characterise, for the first time, the neuroadaptations associated with cannabis dependence relative to regular use via advanced imaging techniques and examine links between neural alterations and quality of life. This study will help to identify new treatment targets and develop a new neural model of cannabis addiction.
Selective Modulation Of Neural Network Activity Using Focal Brain Stimulation

Summary
Transcranial magnetic stimulation (TMS) has been touted as a viable treatment for a range of psychiatric and neurological disorders. However, the extent to which localised TMS influences widespread brain networks remains unknown. To fill this gap, we will combine neuroimaging and TMS in healthy adults. The project will provide a scientific foundation for the use of brain stimulation as an effective tool for improving function in a range of clinical conditions.
Schizophrenia is classified among the world’s top ten enduring disabilities. Hearing voices are a profound and distressing symptom, which have proven difficult to successfully treat. We plan to use the latest brain imaging techniques and genetic testing to develop the most comprehensive understanding of hearing for voices to date. These data are vital to the development of novel tailored treatment for patients who hear voices.
Identifying Novel Markers To Differentiate Frontotemporal Dementia From Alzheimer's Disease

Summary
In people under 65 years of age, frontotemporal dementia and Alzheimer's disease are equally common. Distinguishing between these different types of dementia is extremely challenging. Patients can present with similar symptoms, even when the underlying dementia cause (i.e., brain pathology) is different. Inaccurate diagnosis means patients cannot access appropriate treatments, as these become available. I will develop novel tests of social function to improve the diagnosis of dementia syndromes.
Deep Brain Stimulation For Severe Generalised Epilepsy Of Lennox-Gastaut Phenotype

Summary
Deep Brain stimulation (DBS) is an emerging treatment for epilepsy, recently approved for use in Australia on the basis of trials in focal epilepsy showing benefit. The role of DBS in generalised epilepsy is currently unclear. This study tests the effectiveness of DBS in Lennox-Gastaut Syndrome, a severe, medication-resistant generalised epilepsy syndrome.
Patients with schizophrenia differ widely in their symptoms, long-term outcome and response to medication. However, most patients are treated with the same medications and interventions. This study aims to better facilitate the targeting of novel treatments to groups of patients (biotypes) that are likely to benefit most from a treatment. Groups of patients that share distinct patterns of deficits in brain connectivity will be delineated using state-of-the-art white matter imaging techniques.
Morphological And Spectroscopic Study Of Monozygotic Twins Discordant For Epilepsy

Summary
Understanding the causes of epilepsies is essential for treatment and prevention. In many people with epilepsy the cause is not obvious and is frequently attributed to events at birth or minor head injuries. It is clear that these factors are generally not important. There is increasing evidence that subtle changes in brain structure, reflecting developmental or maturational abnormalities, may be the cause of these epilepsies. Such subtle changes can be detected by novel magnetic resonance imagi ....Understanding the causes of epilepsies is essential for treatment and prevention. In many people with epilepsy the cause is not obvious and is frequently attributed to events at birth or minor head injuries. It is clear that these factors are generally not important. There is increasing evidence that subtle changes in brain structure, reflecting developmental or maturational abnormalities, may be the cause of these epilepsies. Such subtle changes can be detected by novel magnetic resonance imaging strategies. However, due to individual differences of brain morphology, the significance of such subtle changes can be disputed. Monozygotic twins have an increased similarity of their brain morphology. Therefore, analysis of monozygotic twins where only one twin is affected with epilepy, is a powerful way to characterize significant brain abnormalities. This will provide novel information on the causes of epilepsy relevant to the general population.Read moreRead less
