The AI system, developed after eight years of research by the Chinese Academy of Sciences and PLA General Hospital in Beijing, has achieved nearly 90 per cent accuracy on prognostic assessments, according to the researchers.
One 19-year-old patient spent six months with unresponsive wakefulness syndrome – formerly known as being in a vegetative state — after an accident caused a severe injury to his left temple.
Some of China’s best neurologists conducted four rounds of assessments on his potential for recovery and gave him seven out of 23 points on a coma recovery scale, a score which meant his family had a legal right to unplug his life support.
After going through his brain scans, however, the computer gave him more than 20 points, close to the full score.
In another case, doctors gave a 41-year-old female stroke victim who had been in a vegetative state for three months a recovery potential score of six. The computer’s: 20.23.
The young man, middle-aged woman and five other patients whom doctors believed would never recover woke up within 12 months of the brain scan, precisely as predicted.
