Associate Professor Michelle Lupton from QIMR Berghofer featured in a 10 News report on the possible link between bushfire smoke and dementia.
While about 60% of Alzheimer’s disease risk is linked to genetics, environmental factors also play an important role. Air pollution is now recognised as one of the fourteen modifiable risk factors for developing .
Associate Professor Lupton leads the Neurogenetics and Dementia Research Group and is launching a study examining how bushfire smoke impacts brain health in Australia.
Fine particles in bushfire smoke known as PM2.5 can enter the bloodstream and reach the brain, where they are thought to increase inflammation.
With climate change increasing smoke exposure and Australia’s vegetation potentially producing more toxic bushfire emissions, understanding these impacts in the Australian context is critical.
