[The Financial News] A British teenager's life was saved after the AI chatbot service ChatGPT accurately diagnosed his rare neurological disorder.
According to The Sun on the 7th (local time), Callan Isles, 17, who lives in Cirencester, Gloucestershire, visited his local clinic after his cold symptoms worsened. His condition did not improve, and he experienced a sudden loss of strength in his arms and legs.
Callan reported unusual symptoms such as his feet turning blue and difficulty moving. The doctor diagnosed him with Raynaud syndrome, a type of circulatory disorder, and advised him to keep warm and wear gloves.
Despite the doctor's diagnosis, Callan sensed something far more serious was happening to his body. He entered his symptoms in detail into ChatGPT, which he often used for studying. The AI suggested it could be Guillain–Barré syndrome (GBS).
GBS is a rare and difficult-to-treat disorder in which the immune system attacks peripheral nerves, causing paralysis. If the paralysis spreads upward, it can affect the respiratory muscles and become life-threatening, making prompt treatment essential.
Shocked by the AI's diagnosis, Callan informed his mother, Lyn Constantine, and they immediately went to the emergency room. After further tests, the medical team confirmed GBS and transferred Callan to the Royal Hospital for emergency treatments such as plasma exchange.
Callan is currently recovering and is expected to be discharged soon.
In an interview with local media, Callan recalled, "As my symptoms kept getting worse, I became anxious. When I entered them into the AI, it diagnosed GBS. When the hospital told me 'you were right,' I could hardly believe it myself."
He added, "It's crazy that I had to rely on AI for an accurate diagnosis. While my trust in the National Health Service (NHS) as a whole hasn't been shaken, it will affect how I view local General Practitioners (GPs)."
The Sun reported that Callan's case demonstrates the potential for AI to be used as an assistive diagnostic tool in medical settings, while also sparking debate about the need to review and improve the response system at the primary care level.
