What else is your doctor using to treat this? You'll have to ask what is inside the microbubbles.

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.
“With an ageing population placing an increasing burden on the health
system, an important factor is cost, and other potential drug
treatments using antibodies will be expensive,” Professor Götz said.
“In contrast, this method uses relatively inexpensive ultrasound and
microbubble technology which is non-invasive and appears highly
effective.
The approach is able to temporarily open the blood-brain barrier,
activating mechanisms that clear toxic protein clumps and restoring
memory functions.
“With our approach the blood-brain barrier’s opening is only
temporary for a few hours, so it quickly restores its protective role,”
Professor Götz said.
Research has been conducted using mice with an Alzheimer’s model,
with the next step being to scale the research in higher animal models
ahead of human clinical trials, which are at least two years away.
“This treatment restored memory function to the same level of normal healthy mice,” Professor Götz said.
“We’re also working on seeing whether this method clears toxic
protein aggregates in neurodegenerative diseases other than Alzheimer’s
and whether this also restores executive functions, including
decision-making and motor control.”
Findings of the research, “Scanning ultrasound efficiently removes
amyloid-β and restores memory in an Alzheimer's model”, are published in
the journal Science Translational Medicine.
