China joins global race to reawaken brain-injury patients through ultrasound therapy
Chinese researchers have reported early promising results in using focused ultrasound waves to help patients recover from severe brain injuries. A patient in China, after three months in a coma following a brain haemorrhage, reportedly regained the ability to speak, eat, and walk with support as part of an early clinical trial, according to state media.
The therapy employs targeted sound waves to stimulate specific regions deep within the brain. This method, developed by a coalition including the Chinese Academy of Sciences’ Shenzhen Institutes of Advanced Technology, is notable for its non-invasive approach, as it does not require surgery or implanted electrodes to deliver the stimulation.
The focused ultrasound technology aims to "wake up" severely damaged brains, as demonstrated by the patient who regained speech, eating, and supported walking. This particular case, reported by state broadcaster CCTV, highlights a potential new method for restoring consciousness and motor skills in individuals with prolonged brain injury.
However, these reported results stem from an early clinical trial, detailing the outcome of a single patient. While such recovery is significant for an individual, these preliminary findings, attributed to state media, do not yet provide a broad basis for evaluating the general effectiveness or safety of the treatment across a larger patient population.
