TDP-43 In The Population In Relation To Dementia: Relationships With Clinical Symptomatology And Other Key Neuropathologies
Funder
National Health and Medical Research Council
Funding Amount
$235,002.00
Summary
There are over a quarter of a million people with dementia in Australia, and this figure will rise. We still do not understand what goes wrong within the brain to give rise to dementia. This project will assess a new pathology within the brain in relation to late life dementia and the aging process. Results will improve diagnostic tools for dementia and treatments.
Advancing Life Participation Outcomes Following Traumatic Brain Injury (TBI) By Improving Communication Skills: From The Bedside To The Barbeque
Funder
National Health and Medical Research Council
Funding Amount
$782,370.00
Summary
Brain injury is the leading cause of disability in young Australians with sudden and devastating life consequences. One of the most common problems arising from the injury itself is communication difficulties, which leads to relationship breakdowns, unemployability, and crippling social isolation. This Fellowship will deliver pioneering communication treatments using socially innovative eHealth solutions to achieve real improvements for people with brain injury, their families and the community
Centre For Research Excellence In Speech And Language Neurobiology (CRE-SLANG)

Funding Amount
$2,491,340.00
Summary
Half a million Australian children have a speech/language disorder, tripling their changes of poor academic outcomes, limited employment options and social isolation. Current speech therapy is limited, focusing on symptoms and ignoring evidence on underlying aetiologies. By identifying and translating findings on new genes and brain pathways leading to speech and language disorders, we will transform detection, diagnosis, prognosis and genetic counselling of affected children and their families.
Cannabidiol (CBD): A Novel Therapeutic For Alzheimer's Disease.

Summary
Current drugs do not stop or reverse the progression of Alzheimer’s disease (AD). Also, brains of AD patients show a number of biological changes and effective drugs should target those together. Cannabidiol (CBD) has such abilities when tested in AD cell models. We found that CBD can also prevent and reverse memory deficits in AD mice. We propose to provide convincing preclinical evidence for the benefits of CBD for human AD therapy and to define mechanisms involved.
Up to 40% of stroke survivors have aphasia (disturbance or loss of language) and of these, 60% will still be aphasic 12 months post-onset. Up until now, it has not been possible to predict aphasia recovery or response to treatment. This research will use clinical measures and brain imaging to develop better predictors of aphasia recovery.
Cytoprotection By Erythropoietin In Hypoxia-ischaemia Of The Kidney And Brain

Summary
We aim to make a significant research impact by describing the complex mechanisms responsible for protecting kidney and brain cells from stress caused by a lack of oxygen. In particular we will establish whether the compound erythropoietin (Epo), which occurs naturally in the human body but its human recombinant form can also be used as a treatment, may be useful in protecting cells from death following a shortage of oxygen. . We have already described how Epo can protect the kidney, but no one ....We aim to make a significant research impact by describing the complex mechanisms responsible for protecting kidney and brain cells from stress caused by a lack of oxygen. In particular we will establish whether the compound erythropoietin (Epo), which occurs naturally in the human body but its human recombinant form can also be used as a treatment, may be useful in protecting cells from death following a shortage of oxygen. . We have already described how Epo can protect the kidney, but no one has yet described its action on kidney cell differentiation or its effect on structural and vascular support in the injured kidney. When might Epo treatment be effective? Could it protect against chronic renal disease? Likewise, whilst more very pre-term babies survive, this is a crucial period when they are at heightened sensitivity to lack of oxygen and they are at risk of brain damage and poor development because of lack of maturation of key structural cells in the brain. The role of Epo in aiding brain cell maturation and on blood vessel formation and function in this faulty development period is not known. Both of these health problems are major issues causing huge costs to society both financial and emotional. Despite the early evidence of a useful role for Epo in human disease treatment, current experimental and clinical data demonstrate the importance of further thorough investigation of mechanisms and cellular pathways that will underpin improvements in clinical outcomes. A particular strength of our project is that by comparing similarities and differences in the kidney and brain, we will be able to elucidate the mechanisms of action of Epo and its analogues.Read moreRead less
Missing Voices: Communication Difficulties After Stroke And Traumatic Brain Injury In Indigenous Australians

Funding Amount

Summary
Acquired communication disorder (ACD) is a common result of stroke and traumatic brain injury (TBI) and has a devastating impact on victims’ everyday lives. Stroke and TBI occur more than twice as frequently in Indigenous as in non-Indigenous populations, but current uptake of communication rehabilitation services is low and long term outcomes for the individuals are unknown. This Australian first study will examine the extent and impact of ACD in urban and rural Indigenous Australians.
