Ultrasound as a Brain Search and Rescue Tool

Ultrasound, once used almost exclusively to take images of the body, has rapidly evolved into a targeted therapy with potentially life-changing effects on the brain, according to the authors of a new article. It is said that they are doing so.

For decades, medical professionals around the world have used ultrasound as a means to monitor fetal development and assess the health of a patient's internal organs.

But when I write it in my diary PLOS BiologyResearchers from Stanford University, the University of Plymouth, and Attune Neuroscience say their research has been proven to provide a non-invasive and precise way to target specific areas in humans. brain.

This allows the technology known as transcranial ultrasound stimulation (TUS) to treat pain, alcoholism, obsessive compulsive disorder (OCD) and Parkinson's disease, all without drugs or surgery.

In a new paper, the researchers explain how, beyond treatment, the technology could be used to temporarily test areas before treatment, and as a kind of “brain search and rescue tool.” We are debating whether it works.

This allows us to find the causes of brain-related problems and disorders before they are treated, which could be an important path towards personalized treatment.

However, they acknowledge that there are still many complex challenges that need to be addressed before TUS can be deployed globally in healthcare settings and even homes.

These include the fact that each of the planet's 8.2 billion brains and skulls is unique, and work still needs to be done to tailor the technology so that as many people as possible can benefit from it. .

Although this technology has advanced significantly, it is still several years away from reaching a point where it is still effective but sustainable from a cost perspective.

But now researchers are developing and testing TUS devices that are small and simple enough for people to use at home after a series of clinical evaluations, without having to continually travel to hospitals or other medical settings.

This article was written by Dr. Keith Murphy, co-founder of Attune Neurosciences and researcher at Stanford University School of Medicine, and Professor Elsa Fouragnan, who leads the Brain Stimulation Laboratory at the Center for Brain Research and Imaging at the University of Plymouth.

“There are countless reasons why people can't go to the clinic, including financial burden or simply not having the time,” Dr. Murphy said. However, it is safe to use at home. We have always believed that portability is a critical step in making advanced brain treatments available to everyone, and we have made great strides in demonstrating that they work. I did. ”

The researchers also discuss how focused ultrasound can be integrated with other emerging technologies, for example to improve the accuracy and effectiveness of interfaces that allow direct communication between the brain and external devices. .

Professor Foragnan said: 'Over the years we have improved our understanding of how the brain works and the defects within it that lead to neurological and mental health conditions. We are making progress, but the same thing is not happening,” he added. pace.

“We believe TUS can fill that gap, and through our previous research, we have discovered how TUS can become a true search-and-rescue tool for the brain. Clinicians and patients We are excited about the potential and, if the current pace of development continues, we will be able to create a risk-free technology that could positively impact millions, if not billions, of people. You can get it.”
