Successful Ageing In Older Men – Thriving Not Just Surviving In The Health In Men Study

Funding Amount
$628,810.00
Summary
Despite “Ageing well, ageing productively” being listed as a research priority, we still do not know what factors increase the ability for people to live a healthy old age, particularly as they enter their older years. Studies suggest that factors in late life have quite different effects on both survival and the major causes of illness. This application will use a large group of older men who have already been followed for 15 years to determine what increases the chance of successful ageing.
Functional Genomics Approach To Extend Lifespan While Preventing Age-related Cognitive Decline

Funding Amount
$772,600.00
Summary
In our ageing population, preventing age-related neurological decline is one of the central medical challenges of the 21st century. Here we use human population data obtained from people who reached 90 years of age free of any disease, or patients who suffer from dementia, combined with functional genomics studies in animals to pinpoint new genes that can be targeted to extend lifespan while preserving neurological function in these extended years of life.
TDP-43 In The Population In Relation To Dementia: Relationships With Clinical Symptomatology And Other Key Neuropathologies

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.
There are currently no drugs available to prevent or slow deterioration in Alzheimer’s disease – which is a major incurable dementia. Our recent findings demonstrate that high brain iron levels worsen brain performance and cause people to develop Alzheimer’s disease at an earlier point in time. We propose a clinical trial of deferiprone, a drug that lowers brain iron levels, to determine if this would slow deterioration in Alzheimer’s disease once it is first detected.
In Vivo Tau Imaging In Alzheimer’s Disease And Other Dementias

Summary
Alteration of the normal protein tau leads to its deposition inside the brain cells leading to their death. These deposits have been well characterized and they are associated with cognitive impairment. We propose to study tau deposits in vivo in humans using positron emission tomography (PET) and assess its association with cognition and other signs of neurodegeneration
The Healthy Brain Project: A Prospective Cohort Study To Examine How Later-life University Education May Affect The Trajectory Of Ageing-related Cognitive Decline

Funding Amount
$1,085,742.00
Summary
Previous research has indicated that higher levels of education in early adulthood are associated with lower risk for dementia in older adults. This world-first project will examine if older adults who undertake university education have reduced rates of age-related cognitive decline than older adults who do not undertake further education. This would support the notion that boosting cognitive reserve in later life is protective against age- and disease-related neurodegenerative change.
Modifying The Trajectory Of Insidious Late Life Cognitive Decline Using Computerised Cognitive Training

Funding Amount

Summary
Supervised, group-based computerised cognitive training (CCT) is a safe and effective intervention to maintain cognition in healthy older adults. This project will examine the extent to which CCT can attenuate or even reverse the rate of decline in older people with previously documented cognitive decline, as well as strategies to maintain CCT effects in the long term.
Inflammation plays both protective and damaging roles in Alzheimer’s disease (AD), so to identify a long lasting and effective treatment, it is important that we better understand the underlying processes. Our studies implicate a cytokine called interleukin-18 (IL-18) as a factor that accelerates AD pathology. Here we propose to study the mechanisms by which this cytokine alters basic cell biological functions and how these changes affect AD pathogenesis.
An Olfactory 'stress Test' For The Early Detection Of Alzheimer's Disease

Funding Amount
$743,450.00
Summary
Early detection of Alzheimer's disease will be especially important when treatments become available that can slow or halt the progress of the disease. The sense of smell (olfaction) is affected early in the evolution of Alzheimer's disease. We have introduced a simple, inexpensive modification to standard testing of olfaction that we believe may help identify individuals with very early stage Alzheimer's disease. Our study is designed to assess this promising new approach.
An Evaluation Of How Well Brief Screening Instruments Can Classify Safe And Unsafe Older Drivers
Funder
National Health and Medical Research Council
Funding Amount
$877,030.00
Summary
This proposal seeks to evaluate a screening instrument that will assess the safety of older drivers. The assessment takes less than 10 minutes and involves measuring aspects of vision, reaction time, and balance. We will assess this instrument in persons who are potentially at risk of being unsafe drivers due to visual, cognitive or medical problems. The instrument will be evaluated against the results of an on-road driving assessment and compared to other methods of evaluating older drivers.
