Summary
Music can have positive effects on persons with dementia. It be a powerful trigger of memories and emotions and provide a link to one's personal past and a form of communication with carers. Familiar songs can be recognised even in the late stages of dementia when verbal communication and memory for other things may be lost. There has been little scientific investigation of how and why music can help people with dementia and their carers. This research will address this issue.
The Missing Link: MGluR5 As A Therapeutic Target For Cognitive Decline In Dementia

Summary
Cognitive decline is a core feature of Alzheimer’s Disease (AD), yet there is no cure or treatment. Recent evidence suggests that a protein called mGluR5 could cause brain cells to lose function, leading to memory loss. This project will investigate whether disrupting mGluR5 function can improve cognition in mice with genetic AD. Memory will be assessed in mice using innovative touchscreen tests that closely mimic the tests used in humans.
Investigating The Synergistic Role Of Brain-derived Neurotrophic Factor (BDNF) And Estradiol On Parvalbumin-mediated Cognitive Function: Relevance To Dementia

Summary
Estrogen-based therapy may improve cognitive functioning in dementia patients. However, more detailed knowledge is required to ensure safe and effective targeted treatment is provided. I propose to examine, in mouse models, the mechanistic functioning of estrogen signalling in key brain regions involved in cognition. Unravelling the way estrogen impart its beneficial effect can lead to the development of effective treatments for dementia and many other devastating neurological diseases.
A European DNA Bank For Deciphering The Missing Heritability Of Alzheimer's Disease (EADB)

Summary
Understanding the genetics of Alzheimer’s disease (AD) is one of the best ways of improving our knowledge of the underlying mechanisms of disease development. There is evidence that genetic factors account for up to 80% of the risk for AD. Recent advances in genetics still explain <50% of this risk. This proposal will help two major Australian studies to partner with a large European consortium in trying to understand the “missing” heritability, using existing and novel genetic data.
Vascular Mechanisms Of Neurodegeneration: Drivers And Determinants Of Dementia

$6,421,722.00
Summary
The evidence is compelling: vascular burden is the greatest determinant of late life cognition. The volume of evidence linking vascular risk and dementia is conclusive. All late-onset dementia syndromes, especially Alzheimer’s disease, are driven or exacerbated by vascular brain burden. We aim to examine how vascular burden causes dementia. Understanding the mechanisms means that we can prevent and treat the global epidemic of dementia.
Genetic Mechanisms That Moderate Effects Of Aβ Accumulation In Preclinical Alzheimer's Disease

Summary
Alzheimer’s disease (AD) is the most common form of dementia, and the number of people living with it will triple by 2050. There is currently no cure for AD, and the only means of slow the growing epidemic is to delay onset. We propose to understand the complex interplay between genetic, cognitive, neuroimaging and biological markers of AD in order to better understand the disease process, and in turn identify high-risk individuals for clinical trials and uncover disease-modifying strategies.
Cognition-oriented Treatments For Older Adults On The Spectrum From Cognitive Health To Dementia: Improving Methodologies And Outcomes

$716,620.00
Summary
Older adults, with and without memory problems, frequently seek ‘brain stimulating’ activities to reduce their dementia risk. Many such activities are available, but the evidence behind them is not clear and more research is needed to improve our understanding of these treatments. The proposed research programme aims to support older adults interested in these types of activities in their efforts to remain cognitively healthy and functionally independent irrespective of age and clinical status
Improving The Health Of Older Australians At Risk Of Dementia - The Role Of Physical Function And Exercise

Funding Amount
$533,120.00
Summary
This fellowship will support novel research to examine whether exercise can improve the cognitive and physical health of individuals at risk of dementia such as those with Type 2 Diabetes or cognitive impairment. Outcomes are likely to delay the onset of dementia and enable older Australians at risk of dementia to maintain independence and improved quality of life.
Vascular Contributions To Dementia: Prevention In Those At High-risk

Summary
10,000 older adults undergo surgeries on their heart every year. These adults are at high risk for dementia, as the factors that bring them to cardiovascular surgery are the same as those that associate with dementia: hypertension, type II diabetes, etc. This population is in fact not only at increased risk of dementia due to vascular ill-health, but also because of undergoing the surgery itself. This project aims to prevent dementia in this vulnerable group.
Vasoactive Nutrients To Promote Healthy Ageing In Postmenopausal Women

Summary
Poor circulatory function in the brain, associated with mood and cognitive disturbances, can be further exacerbated by ageing and estrogen deprivation at postmenopause. My research will determine whether phytoestrogen supplementation with either resveratrol or genistein for 2 years can counteract menopause-related impairments in mood and mental performance by enhancing cerebral vasodilator function and whether the magnitude of improvement differs between early and late menopausal years.
