The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

A Randomised Double Blind, Placebo-controlled Study Of Nefiracetam In Patients With Post- Stroke Apathy
Funder
National Health and Medical Research Council
Funding Amount
$865,271.00
Summary
A wide range of emotional and cognitive disturbances are observed following stroke. Apathy is expressed by diminished initiation and poor persistence on tasks, lack of interest, emotional indifference and low social engagement. Our preliminary study has suggested that the medication nefiracetam significantly improves apathy among stroke patients. The main aim of our project is to conduct a large scale study to determine whether nefiracetam improves apathy in patients with stroke lesions.
Exercise Reverses Cognitive Decline In Aged Animals By Growth Hormone Stimulation Of Neurogenesis In The Hippocampus
Funder
National Health and Medical Research Council
Funding Amount
$696,409.00
Summary
The production of new neurons in the hippocampus plays a critical role in learning and memory. With increasing age, this production slows and is associated with cognitive decline. However the stem cells that make new neurons are still present, and we have discovered that exercise activates these cells, leading to renewed neuron production and reversal of cognitive decline. We will explore how this process is regulated in order to develop strategies to reduce cognitive decline in humans.
ASPREE- NEURO; Aspirin And Cerebral Microhaemorrhages

Funding Amount
$989,195.00
Summary
Cerebral Microhaemorrhages (CMH) are tiny areas of blood vessel breakdown commonly found on brain MRIs in the elderly. Their clinical significance is not clear- prior studies have linked them to use of blood thinning medications, cognitive decline and risk of stroke. This randomised controlled trial will determine whether low dose aspirin increases the number of CMH on brain MRI in the healthy elderly after 1 and 3 years, and whether the number and location of CMH affects cognitive function.
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.
Epistatic Genetic Effects On Neuroanatomical Subtypes Of Schizophrenia

Summary
Schizophrenia represents a number of clinically distinct syndromes, with a complex mode of inheritance. The delineation of biologically valid subtypes of schizophrenia is necessary to advance our understanding of the genetic basis of these syndromes. This project uses pattern classification techniques to determine subtypes of schizophrenia on the basis of structural brain abnormality across multiple regions, and will examine genetic interactions and differential gene expression associated with t ....Schizophrenia represents a number of clinically distinct syndromes, with a complex mode of inheritance. The delineation of biologically valid subtypes of schizophrenia is necessary to advance our understanding of the genetic basis of these syndromes. This project uses pattern classification techniques to determine subtypes of schizophrenia on the basis of structural brain abnormality across multiple regions, and will examine genetic interactions and differential gene expression associated with these biologically-derived subtypes.Read moreRead less
Optimum Thiamine Dose For Treatment And Prevention Of Wernicke-Korsakoff Syndrome (WKS): A Randomised Controlled Trial Targeting Aboriginal People.

Funding Amount

Summary
Wernicke-Korsakoff syndrome (WKS), once thought to be a rare condition, is now known to be common in people with nutritional deficiencies or alcohol dependence. WKS may lead to significant, long-term brain dysfunction with severe effects on work, personal and social function. Whilst effective treatment may greatly reduce severe disability and the human and social costs of this illness, almost no evidence exists on optimal dosing regimens. This project proposes to develop quality evidence for eff ....Wernicke-Korsakoff syndrome (WKS), once thought to be a rare condition, is now known to be common in people with nutritional deficiencies or alcohol dependence. WKS may lead to significant, long-term brain dysfunction with severe effects on work, personal and social function. Whilst effective treatment may greatly reduce severe disability and the human and social costs of this illness, almost no evidence exists on optimal dosing regimens. This project proposes to develop quality evidence for effective treatment of WKS in an Aboriginal setting.Read moreRead less
Identification And Quantification Of HIV Latency Biomarkers In The Central Nervous System
Funder
National Health and Medical Research Council
Funding Amount
$814,618.00
Summary
One major obstacle in curing HIV is the brain’s role as a potential reservoir of HIV infection. It is unknown if “reawakening” of HIV may lead to uncontrollable brain damage given that current antiretroviral drugs vary in their ability to treat brain infection. Not all patients have HIV brain infection so eradication therapies in themselves may be safe. We aim to identify and quantify biomarkers of HIV latency in the brain to stratify patients into these two cohorts.
Motor Passivity Symptoms In Schizophrenia And Mental Representations Of The Body
Funder
National Health and Medical Research Council
Funding Amount
$220,180.00
Summary
Individuals with schizophrenia who report passivity symptoms feel that they are no longer in control of their movements and believe that their actions may be willed by some other power. This research aims to examine a set of mental processes which determine how the body is 'represented' in the brain and which, if disrupted, can lead to disorders of body experiences. The outcome of the study will lead to a greater understanding of passivity symptoms and can be used to plan interventions.
