Why does stress increase dementia risk and what can be done?

The ISLAND Resilience Initiative

Stressful life events have been linked to dementia and can profoundly impact our brain health and wellbeing. Why does stress increase dementia risk and what can be done? The ISLAND Resilience Initiative is an ISLAND sub-study which aims to answer these questions with the help of ~1300 research participants. The study is investigating many types of stressful experiences across the lifespan, but is particularly tailored to understand impacts of natural disasters and bushfires. The ISLAND Resilience Initiative launched in 2021 and is a collaboration between researchers at the University of Tasmania, Southern Queensland University and the Tasmanian Department of Health.

 

We consider resilience to mean the ability to withstand or recover from stressful/traumatic experiences. Understanding resilience encompasses 1) identifying the short- and long-term impacts of bushfires/natural disasters and other stressful events on our brains, bodies, lives, families and communities; and 2) identifying factors which strengthen or weaken resilience. Building resilience involves developing, testing, evaluating and making available strategies for enabling Tasmanians to increase their resilience.

 

Activities conducted and/or currently underway in this study include:

o   Community consultations to establish research priorities;

o   Establishment of the Resilience Initiative Advisory Group;

o   Survey data collection about participants’ physical health, mental health, perceived stress, resilience, coping and life experiences;

o   Measurement of stress-related biological parameters in hair, saliva and blood;

o   Development, testing and optimisation of the Bushfires and Your Health short course, to increase understanding and preparedness for bushfires (this short course is free and now publicly available);

o   Involvement of advisory group members, participants and other stakeholders in co-production of a research plan for post-disaster research.
