Researchers from the University of Queensland in Australia have made significant advancements in using ultrasound technology to treat Alzheimer’s disease. This innovative therapy potentially boosts cognitive functions in people suffering from this neurodegenerative disorder.
For many years, Alzheimer’s disease has remained a major challenge for medical science, impacting millions of individuals worldwide. Current treatments only manage symptoms rather than halt or reverse the disease’s progression. However, the team at the Queensland Brain Institute believes their approach could change that.
The research, led by Professor Jurgen Gotz, has focused on a form of ultrasound therapy that uses targeted pressure waves to stimulate the brain. This technique encourages better communication between brain cells and helps clear harmful proteins associated with Alzheimer’s, namely amyloid and tau proteins.
Published in the journal *Molecular Psychiatry*, the study highlights promising results obtained over a decade of testing on rat models. The first human safety trial of the ultrasound therapy was completed successfully in 2024 under the guidance of Professor Peter Nestor. Results from this trial are expected to be released later this year.
Professor Gotz explained, “The therapy increases neuronal signaling and thereby restores memory and cognition by enhancing communication between brain cells.” He added that the technology targets and clears the buildup of toxic proteins by activating the brain’s natural cleaning mechanisms.
In December 2024, the ultrasound technology was licensed to a startup named Ceretas, which aims to further develop the device for clinical use. Ceretas plans to validate the system for treating Alzheimer’s as well as other neurological disorders, including frontotemporal dementia and amyotrophic lateral sclerosis (ALS).
The potential of therapeutic ultrasound offers a non-invasive and personalized treatment option, a huge step forward in the fight against Alzheimer’s and other brain-related diseases. With ongoing trials and research, the future looks hopeful for those affected by such debilitating conditions.
