The University of Utah has announced the creation of an ultrasonic gadget that can alleviate chronic pain and depression without medication. The device has been named Diadem. Diadem uses ultrasound stimulation of deep regions of the brain to block the signals that lead to chronic pain. The study involved 20 patients, each of whom underwent two 40-minute sessions. Half of the participants received real stimulation and the other half received sham stimulation, which eliminated the effect of self-injury. The results showed that 60% of the patients in the real stimulation group had significantly reduced pain the very next day. The results of the first human clinical trials showed that the device effectively eliminates pathological signals in the brain that cause “false alarms” and pain sensations even in healed areas or amputated limbs. Also, according to the authors of the development, the prototype is able to cure depression in one 40-minute session. At the moment, scientists are preparing for the final phase of clinical trials, which will make it possible to introduce the diadem into medical practice.
