The comatose patient unexpectedly regained consciousness thanks to ultrasound waves.

A 25-year-old American man in a deep coma due to a traumatic brain injury suddenly woke up after doctors implanted an ultrasound-emitting device to restart his brain.

Previously, the patient showed only minimal signs of cognitive ability and speech comprehension.One day after the ultrasound device was implanted, his response improved significantly. By the third day, the patient had fully regained consciousness, able to communicate by nodding or shaking his head, and even gesturing with his hands to greet the doctor.

According to the Independent, the ultrasound device was invented by a professor of psychiatry.Alexander Bystritsky from the University of California (USA) created a device the size of a coffee saucer. It creates an energy sphere that can "shoot" to various parts of the brain. In the case of a 25-year-old man, researchers placed the device in the patient's brain and activated it 10 times, each time for 30 seconds.

Professor Martin Monti, who participated in this treatment, said: "We almost completely restarted the brain, bringing the nerve cells back to normal function." He affirmed that this method affects the thalamus but is non-invasive and carries fewer risks than the previously used method of directly implanting electrodes into the brain. Furthermore, the device is very safe because it uses less energy than ultrasound techniques used to examine fetuses in the womb.

The team of scientists is now planning to test the ultrasound waves on other patients.If successful, they could create a handheld device that would "awaken" people who are in a vegetative state or have limited awareness.
