Summary
The burden associated with heroin dependence is undeniable. But little is known about the natural history and long-term course of heroin dependence; knowledge that is critical for informing the development of new treatment interventions, health care planning and service delivery. We propose to extend our study of 615 Australians with heroin dependence, recruited in 2001-2002, to 18-20 years follow-up to answer critical questions about the long-term impact of this condition.

Summary
Sensory loss and dementia disproportionately affect older adults, often co-occur, and are the two leading contributors to disability burden among older Australians. This research will investigate the consequences that hearing and vision loss have for older adult health and wellbeing, informing strategies to reduce the disability burden of age-related sensory loss. These impacts include cognitive decline and dementia, mental health, quality of life, disability and independent living.

Summary
Parkinson s disease (PD) is a progressively disabling movement disorder afflicting many elderly Australians. It is caused by the degeneration of specific nerve cells in the brain that produce certain chemicals and patients suffer from an inability to move fluently (or ultimately at all). At present we do not know what triggers this neurodegeneration, but it is believed that complex interactions between inherited (genetic) and environmental factors contribute significantly to the phenomenon.

It is caused by the degeneration of specific nerve cells in the brain that produce certain chemicals and patients suffer from an inability to move fluently (or ultimately at all). At present we do not know what triggers this neurodegeneration, but it is believed that complex interactions between inherited (genetic) and environmental factors contribute significantly to the phenomenon. This project aims to learn more about these complex interactions and their association with PD. People with PD and unaffected individuals will be recruited from throughout Australia and we will look for specific combinations of genetic, environmental and lifestyle factors that either increase or decrease an individual's risk for PD. This research will identify the most common dominant genetic and environmental influences for PD in Australia, enabling scientists to focus on the most relevant biological pathways to target therapeutically.Read moreRead less
A new scan called PiB PET shows the build up of amyloid protein deposits in the brain in all patients with Alzheimer's disease (AD) but also in 30% of normal elderly persons. This study will track the build up of amyloid and clinical progress in 280 elderly Australians to confirm that this scan can detect AD before symptoms and investigate factors that influence this build up and its damaging effects on memory and thinking. Early detection of Alzheimer's disease will assist accurate diagnosis an ....A new scan called PiB PET shows the build up of amyloid protein deposits in the brain in all patients with Alzheimer's disease (AD) but also in 30% of normal elderly persons.

Funding Amount
$1,086,274.00
Summary
There is concern about rising levels of opioid analgesic prescribing in Australia. This study is important because it will provide evidence about long term outcomes for patients using opioid therapy for chronic non-malignant pain. It will examine prescribing patterns and link them to other health outcomes such as overdose. We will also study patients beginning opioid therapy for chronic pain and follow them up over 2 years to examine outcomes such as pain relief and medication side effects.

Summary
The PATH Through Life study is a longitudinal study of depression, anxiety, alcohol and drug use. It is also a study of normal cognitive development, mild cognitive impairment and dementia. PATH involves three cohorts of adults who were aged 20-24, 40-44 and 60-64 at baseline. They are followed up at four yearly intervals. This application seeks funding for Wave 3 of the study, which will allow for 8 years of follow-up of the baseline sample to be conducted.

It is also a study of normal cognitive development, mild cognitive impairment and dementia. PATH involves three cohorts of adults who were aged 20-24, 40-44 and 60-64 at baseline. They are followed up at four yearly intervals. This application seeks funding for Wave 3 of the study, which will allow for 8 years of follow-up of the baseline sample to be conducted. The key aims are to discover the relationships between biological and psychological processes in depression, anxiety, substance abuse and cognitive ageing; to identify the socio-demographic factors contributing to these disorders, and to quantify more fully the range of social and economic consequences of mental illness and cognitive decline. Such consequences include reduced workforce participation, relationship breakdown, family and carer burden, suicide attempts, use of health services and need for social welfare. Wave 3 will also focus on transitions into parenthood, fertility and mental health, menopause, and retirement. Factors in early and mid-adulthood that influence healthy ageing and cognitive decline in late life will be identified. Information is obtained on physical health, health habits , social networks, employment and work stress, lifestyle activities, personality, family structure, physical function and cognitive performance. DNA has also been obtained and a sub-sample of the oldest cohort also participate in a study of brain MRIs. Longitudinal analysis is the only means of distinguishing the causes of disorders and tracking their development within individuals. PATH is unique in its narrow age-group design and breadth of measures, allowing for detailed understanding of the pathways to mental health and illness, and for identification of how to prevent mental illness and dementia.Read moreRead less

Summary
The Blue Mountains Eye Study 15-year study will re-examine survivors of the 3,654 persons who participated in baseline BMES exams, to determine the long-term development and progression of sensory problems, including vision and hearing loss and eye diseases like macular degeneration, glaucoma, cataract or diabetic eye damage.

The project will assess whether vascular conditions like high blood pressure, chronic medical conditions, medications, smoking, diet, blood, family and genetic factors predict the risk or age at onset of eye disease or hearing loss. We will assess impacts of vision and hearing loss on independence, falls, quality of life and development of memory loss and depression. This information will help to develop services, and to plan interventions to prevent and treat these conditions. Because of the exponential age-related increase in frequency of these diseases, this long follow-up will provide more disease events, and a longer interval to assess impacts from the exposures we measured when we started the BMES in 2002. It will enable us to estimate the strength of risk factors for eye disease and hearing loss with greater precision, essential to understand their evolution. Surviving participants from the original BMES will be invited to attend follow-up exams at our Katoomba clinic, or to attend mobile- nursing home exams. We will conduct similar exams to those previously to detect new or worsened eye disease or hearing loss. In 2002-4, we saw 82% of the population of 2 Blue Mountains postcodes aged 50 or older. At the 5- and 10-year exams we saw 75% of people still living. We expect the same proportion to participate this time. The BMES is one of Australia's main cohort studies with over 200 publications. It has yielded key findings on the frequency and causes of the major diseases threatening vision and hearing. Longer follow-up will greatly increase our power to detect predictors of these key age-dependent conditions.Read moreRead less
Preventive messages and guidelines to reduce sitting — especially prolonged periods of sitting — have emerged. However, what prolonged sitting should be replaced with, and the feasibility of making real world changes to this behaviour, is unknown. This program of research will provide high quality evidence on the benefits of reducing prolonged sitting time, and the effectiveness and acceptability of achieving sitting reductions in real-world contexts.
