Queensland scientists have found that non-invasive ultrasound technology can be used to treat Alzheimer’s disease and restore memory.
University of Queensland researchers discovered that the innovative drug-free approach breaks apart the neurotoxic amyloid plaques that result in memory loss and cognitive decline.
Welcoming the findings today at UQ’s Queensland Brain Institute, Queensland Premier Annastacia Palaszczuk said they could have a wide impact for the community.
“The Government’s $9 million investment into this technology was to drive discoveries into clinics, and today’s announcement indicates that together with the Queensland Brain Institute, it was a worthwhile investment,” Ms Palaszczuk said.
“I want my Government to encourage more of this type of innovative research.
“Our Advance Queensland initiative aims to increase research and discoveries like this and to put this state’s research at the forefront internationally by supporting local researchers and helping to keep them in Queensland.
“These exciting findings will hopefully be of benefit to all Australians in the future.”
QBI Founding Director Professor Perry Bartlett said the discovery – a result of ‘game-changing’ work performed at the Queensland Brain Institute’s Clem Jones Centre for Ageing Dementia Research – was made possible through the support of the State and Federal Governments and philanthropic support led by the Clem Jones Foundation.
“The farsighted investment of government and philanthropic partners has allowed us to build the research excellence and capacity required to make major discoveries such as this,” Professor Perry Bartlett said.
“I believe the work opens up an entirely novel avenue for future therapeutic treatment.”
Clem Jones Centre for Ageing Dementia Research director Professor Jürgen Götz said the new treatment method could revolutionise Alzheimer’s treatment by restoring memory.
“We’re extremely excited by this innovation of treating Alzheimer’s without using drug therapeutics,” Professor Götz said.
“The ultrasound waves oscillate tremendously quickly, activating microglial cells that digest and remove the amyloid plaques that destroy brain synapses.
“The word ‘breakthrough’ is often mis-used, but in this case I think this really does fundamentally change our understanding of how to treat this disease, and I foresee a great future for this approach.”
Alzheimer’s affects more than two-thirds of dementia patients, and approximately a quarter of a million Australians.
The total number of dementia cases in Australia is expected to rise to 900,000 by 2050.
