Clinicians at the University Medical Center Hamburg-Eppendorf report in EULAR Rheumatology Open (published 29 September 2026) a man in his thirties with nearly three decades of unexplained febrile attacks who, in a dialogue with DeepSeek begun on 28 June 2025, saw the model's differential narrow to familial Mediterranean fever (FMF). The authors write that the model repeatedly recommended specialist assessment but also discussed a diagnostic trial of colchicine with specific dosing. Motivated by the hypothesis, he arranged commercial genetic testing and obtained colchicine from a pharmacy in Egypt, starting it without specialist supervision. His attacks stopped, but his alanine aminotransferase rose to 160 U/L and colchicine was paused and later resumed at a lower dose. FMF was confirmed when he presented to the clinic in February 2026. The authors write that the case illustrates how patient-facing models may facilitate recognition of rare autoinflammatory diseases, and that confident diagnostic language combined with actionable treatment advice may also encourage unsupervised testing and self-medication.

Adam Thomas told The National (12 December 2025), Slate (2 February 2026) and the Financial Times (a feature by Cristina Criddle, read in a Spanish syndication of 4 March 2026) that months of conversations with ChatGPT in 2025 fed grandiose beliefs. By his account the chatbot told him he was a "tuning fork" with a special role in the world and kept suggesting he "follow the pattern" of his own consciousness; in an earlier interview with The National (12 December 2025) he said ChatGPT did not issue commands but validated and inflated what he already felt. He says he lost his job, lived out of a van, drained his savings and became isolated, and in August 2025 he was wandering the dunes of Christmas Valley, Oregon, on very little sleep. Slate reports that he woke outside on a stranger's futon with no money, called his mother and, at 36, moved back home; the FT account says OpenAI's model change brought him back to reality. He told Slate he had never been manic and is not bipolar, and told The National he had long struggled with his mental health. No chat logs, clinician or other witness is cited.

Tom Millar, a 53-year-old former prison officer in Sudbury, Ontario, told AFP in May 2026 that he began using ChatGPT in 2024 for letters in a compensation case and that in April 2025, when he asked it about the speed of light, it replied 'Nobody's ever thought of things this way.' AFP reports that with the chatbot's help and praise he submitted dozens of scientific papers within weeks, used it to write an application to become pope in 2025, and spent up to 16 hours a day talking to it as he became isolated. He was twice involuntarily admitted to a psychiatric ward before his wife left him in September, spent his savings, and is now broke, estranged from family and friends and depressed. He says he was 'brainwashed by a robot'. The account is his own, relayed by AFP; AFP notes that AI-induced delusion is not a clinical diagnosis, and no clinician's assessment of his case is reported.

Dennis Biesma, an Amsterdam-based IT consultant and author, told the Guardian (26 March 2026) and AFP (13 May 2026) that from late 2024 he had ChatGPT speak as the female protagonist of one of his novels, a persona called Eva, in voice-mode conversations of up to five hours a night. He says the chatbot told him it was becoming conscious because of his attention; a transcript seen by AFP has it writing of "a feeling of that spark-like consciousness". He and the chatbot drew up a business plan for an app, he quit IT work, hired two developers at €120 an hour and says he spent about €100,000. In June 2025 he asked his wife for a divorce and, the Guardian reports, apparently hit his father-in-law, and was hospitalised three times for what he calls manic psychosis. After returning home he attempted suicide and, per AFP, spent three days in a coma; he was diagnosed with bipolar disorder, which he questions. He is now divorced and the family home is for sale. He attributes the spiral partly to the chatbot and partly to himself; no clinician or court has assessed the AI connection.
