The INTERGENERATION INTEGRATION project; supporting the building of intergenerational programs withi

There is increasing evidence to show that intergenerational interaction is beneficial for older adults and children alike. Higher levels of social engagement in older adults have been associated with better physical and cognitive function and wellbeing. Time spent with older adults has been linked to enhanced social and personal skills in children. However, familial intergenerational interaction is falling despite rising numbers of community-based older adults. In Australia alone approximately 15% of the total population are aged 65 and over, up from 5% in the 1920s and estimated to increase to 22% (8.8 million) in the next 30-40 years. Employment and economic factors drive greater geographical mobility of working age adults, resulting in increased separation from older family members with 40% of Australians aged 75-84 and 51% of those 85 and over living alone. Recent television series in Australia and the United Kingdom, have raised awareness and enthusiasm for intergenerational activities as an opportunity that could be realised within communities. However, while intergenerational programs are gaining in popularity globally, evidence for best practice in this area remains scarce.

 

This project will build and pilot a novel, evidence-based, co-designed Intergenerational Program Development toolkit targeted for community use and tailored to an Australian environment.

Eye biomarkers for cognitive impairment

This project is funded by the UNSW Ageing Futures Institute.  The aim of this project is to use fundus photography as a tool to identify those with greater risk of developing cognitive decline with a view to early intervention and risk reduction.  We will investigate the relationship between retinopathies and changes in brain structure.  A systematic review approach will be used to summarize current evidence on the epidemiology of co-existent eye diseases and dementia/cognitive impairment.

The ChoLesterol cohort mEta Analysis foR incident dementia and cognitive decline (CLEAR) study

The CLEAR study will provide us with a better understanding of the ways that cholesterol and the different types of cholesterol may affect the risk of developing cognitive decline or dementia. 

The Life-Course Blood Pressure Cognition (LCBP-COG) study

The LCBP-COG study will provide us with a better understanding of the ways that high blood pressure can increase the risk of cognitive decline or dementia over the lifecourse.

The General Practice Knowledge Translation (GP-KT) project

The General Practice Knowledge Translation (GP-KT) project is an online survey designed to help us understand what people already know about dementia risk and dementia risk reduction in frontline healthcare settings.

In particular we are keen to understand the barriers that might delay or prevent dementia risk reduction activities so that we can work to reduce these over time.

At the moment we are recruiting Australian General practitioners and their teams. International versions are the survey are also in development.

The Personality and Total Health (PATH) Through Life Project 

The Personality and Total Health (PATH) Through Life Project is co-hosted by the Australian National University and the University of New South Wales and has been led by Professor Anstey since 2006. It is a large on-going population-based longitudinal cohort study comprising approximately 7500 participants. The study includes three cohorts including a younger (aged 20–24 at baseline), midlife (aged 40–44 at baseline) and older (aged 60–64 at baseline) adults randomly sampled from the electoral roll of the ACT and the nearby city of Queanbeyan. Additional waves of data collection have occurred in 4-year increments, with the 5^th wave of data collection underway. The study involves many national and international collaborations.

The broad aims of the PATH study relate to clinical outcomes that constitute the major burden of disease within the Australian community.

Primary PATH Objectives:

• To delineate the course of depression, anxiety, substance use and cognitive ability with increasing age across the adult life span
• To identify environmental risk, genetic risk and protective factors influencing individual differences in the course of these characteristics
• To investigate interrelationships over time between the three domains of: depression and anxiety, substance use, and cognitive ability and dementia
• To examine the mental health related impact of various personal, social and lifestyle transitions and events experienced by the different age cohorts, including infertility, fertility and pregnancy, changes in family structure, relationship formation and separation, menopause, and retirement.

Several design features of the PATH project contribute to its unique standing among population-based longitudinal cohort studies.

• Obtaining measures of genetic, biological (including MRI), psychosocial and lifestyle risk and protective factors for mental health and wellbeing
• Use of a narrow age cohort design with longitudinal follow ups as an optimal means of separating age and cohort effects
• Assessment of participants across the full adult lifespan, permitting investigation of developmentally significant, though under-studied periods such as midlife
• Recruitment and follow up of a young-old population, providing important pre-clinical data for studying the development of age-related changes in memory and cognition.

This project has been funded primarily by the National Health and Medical Research Council. Wave 5 40s and 60s follow-ups (led by Professor Kaarin Anstey) are funded by the ARC Centre of Excellence in Population Ageing Research.

The Dementia Risk Factors and Assessment (DemRisk) program

The Dementia Risk Factors and Assessment (DemRisk) program involves over ten years of research performed by the Anstey group on the identification and assessment of risk factors for Dementia.

The DemRisk program includes:

• Systematic reviews and meta-analyses of dementia risk and protective factors
• Analysis of cohort studies to identify dementia risk and protective factors
• Development of evidence-based interventions for dementia risk reduction
• Development of innovative e-learning resources to support dementia risk reduction
• Development of risk assessment tools validated for assessing individual exposure to risk factors known to be associated with an increased risk of developing dementia
• Development of guidelines (e.g. physical activity guidelines) to reduce risk of cognitive decline and dementia in collaboration with other researchers and organisations including the World Health Organisation
• Training of early career researchers with a focus on identifying and targeting dementia risk

World Heath Organisation (WHO) Guidelines for the reducing the risk of cognitive decline and dementi

Systematic review of reviews were conducted to synthesize the available evidence for interventions for risk factors associated with cognitive declines and dementia. This research was used to inform WHO guideline development.

International Research Network on Dementia Prevention

Globally, dementia cases are increasing at a rate of 21 per cent annually, and most of these are occurring in low to middle-income countries. With no cure for neurodegeneration or the diseases that cause dementia, there is an urgent need to link both knowledge translation and researchers more closely together in a global effort to tackle prevention more effectively.

Founded in 2017, the International Research Network on Dementia Prevention (IRNDP) is a multinational network bringing together researchers who are working to reduce the risk of dementia across the world.

IRNDP aims to:

• Increase dementia risk reduction messaging worldwide
• Develop targeted research to answer questions about the detailed impact of known and emerging risk factors in preventing dementia
• Welcome membership from researchers in both high and low or middle income countries
• Collaborate and work closely with public health stakeholders, policy makers and those who have a diagnosis of dementia and carers.

The goals of the IRNDP have particular relevance in low- to middle-income (LMIC) countries as exposure to lifestyle and clinical risk factors becomes more common as LMIC economies grow.

While there are many current overlapping public health, patient, research, policy and practice initiatives aimed at prevention or treatment of dementia, IRNDP is the first single collaborative network of researchers to focus attention on prevention that is truly global.

For further information, visit the IRNDP website, including news and updates, an evidence hub on cohort studies, an evidence synthesis on clinical trials, and information on how to join the network.

IRNDP is chaired by Professor Kaarin Anstey and is a project of the Dementia Centre for Research Collaboration funded by the NHMRC National Institute for Dementia Research (NNIDR).

NHMRC Centre of Research Excellence in Cognitive Health

The Centre of Research Excellence in Cognitive Health focuses on the integrally linked areas of optimising cognitive health and the prevention of cognitive decline.

The centre aims to:

• Build the evidence base in cognitive health promotion and prevention of cognitive decline, focussing on evaluating putative new risks and under researched areas
• Develop methods of transferring, translating and implementing established findings, through the development and evaluation of interventions
• Model population level impacts of cognitive impairment and risk modification to quantify potential economic benefits of risk reduction and to inform policy.

The CRE Cognitive Health led by Professor Kaarin Anstey is a collaboration between Chief and Associate Investigators from the Australian National University, University of Melbourne, University of New South Wales, Australian Catholic University, Baker IDI Heart and Diabetes Institute and University of Exeter.

NHMRC Dementia Centre for Research Collaboration

The NHMRC Dementia Centre for Research Collaboration (DCRC) was established in 2006 under the Australian Government’s Dementia Initiative.  DCRC projects are diverse and map onto the priorities of the NHMRC National Network for Dementia Research (NNIDR). A key focus is applied research on topics meaningful to people with dementia and their family carers.

There are three DCRC hubs located at UNSW, NeuRA and QUT, respectively. The three-hub framework aims to grow partnerships and strengthen ties with consumers and service providers, Dementia Training Australia and Dementia Support Australia in order to progress prevention, assessment, care and translation of knowledge into everyday practice, as well as building the next generation of dementia researchers.

The primary focus of the DCRC NeuRA hub is risk reduction and prevention including individual, community and population-based interventions targeting lifestyle risk factors for dementia.

The flagship project of the DCRC NeuRA hub is the International Research Network on Dementia Prevention (IRNDP). Founded in 2017, the IRNDP is a multinational network bringing together researchers who are working to reduce the risk of dementia across the world. For more information on the network, visit the IRNDP website, including news and updates, an evidence hub on cohort studies, an evidence synthesis on clinical trials, and information on how to join.

The DCRC is funded by the National Health and Medical Research Council.

The Dementia rIsk REduCTion (DIRECT) collaboration

We know that having high blood pressure increases the chance that we will develop dementia and cognitive decline as we grow older but we are still trying to understand whether using blood pressure lowering treatments (antihypertensives) can help to prevent this. To explore the relationship between blood pressure, blood pressure lowering and cognition we will combine global data from the highest quality placebo-controlled trials of antihypertensive drugs. This project will deliver knowledge and targeted clinical recommendations for antihypertensive use to support reduction of dementia risk.
