Summary
The number of people with dementia is increasing in Australia as people live longer. Dementia sometimes has a genetic basis and identification of such cases has improved our understanding of the events leading to the destruction of the brain tissue. In the vast majority of people, the degenerative changes were previously thought to be as a result of Alzheimer's disease. However, our recent research, funded by the NHMRC, confirms international findings showing more than 25% of people with dementi ....The number of people with dementia is increasing in Australia as people live longer. Dementia sometimes has a genetic basis and identification of such cases has improved our understanding of the events leading to the destruction of the brain tissue. In the vast majority of people, the degenerative changes were previously thought to be as a result of Alzheimer's disease. However, our recent research, funded by the NHMRC, confirms international findings showing more than 25% of people with dementia have a different disease called Dementia with Lewy bodies or DLB. Of course identifying these patients occurs at death when the cells in the brain can be examined for Lewy bodies. We now know that the brain degeneration differs significantly in patients with this disease. However, it is still not possible to identify DLB in life with any certainty. This project aims to develop objective methods to clinically differentiate dementia patients. We will seek out families in which genetic influences may underly the disease and determine whether these factors differ from those found in other dementing illnesses. Also, our preliminary studies have observed volume loss in a particular brain region in pathologically confirmed DLB patients. We wish to do further measurements to determine if tissue loss in this region can clinically differentiate DLB patients. In addition, we will determine the reasons for the tissue loss by careful pathological studies.Read moreRead less

Summary
Osteoarthritis is the most common cause of musculoskeletal disability and cost in Australia. Both genetic and environmental factors have been implicated as causes of this disease. As yet, however, there are no proven strategies for prevention of this very common condition and treatment of established disease is unsatisfactory. Part of the reason for this is the fact that there is no sensitive and accurate measure of early disease. In this study, we plan to evaluate knee cartilage volume assessed ....Osteoarthritis is the most common cause of musculoskeletal disability and cost in Australia. Both genetic and environmental factors have been implicated as causes of this disease. As yet, however, there are no proven strategies for prevention of this very common condition and treatment of established disease is unsatisfactory. Part of the reason for this is the fact that there is no sensitive and accurate measure of early disease. In this study, we plan to evaluate knee cartilage volume assessed by magnetic resonance imaging. This is a promising new candidate which is both accurate and sensitive. We will be measuring knee volume both cross-sectionally and longitudinally in the offspring of patients who have had knee replacement for osteoarthritis and comparing them to randomly selected controls to see if knee volume can be utilised as a marker of early or asymptomatic disease particularly in identifying which treatments may be effective at preventing osteoarthritis in later life.Read moreRead less
