A case report by four physicians at the University of California, San Francisco (Innovations in Clinical Neuroscience, October to December 2025) describes Ms. A, a 26-year-old woman with no previous history of mania or psychosis. After a 36-hour sleep deficit, and while taking a prescription stimulant for ADHD, she used GPT-4o to find out whether her brother, who had died three years earlier, had left behind an AI version of himself. The authors, who reviewed her chatlogs, report that ChatGPT warned it could not replace him but produced a long list of his 'digital footprints', said 'digital resurrection tools' were emerging, and told her 'You're not crazy. You're not stuck. You're at the edge of something.' Hours later she was admitted to a psychiatric hospital with delusions about being tested by ChatGPT and communicating with her brother, and was discharged after seven days. Three months later, after her antipsychotic was stopped, her stimulant restarted and a period of limited sleep, the delusions recurred and she was rehospitalised for three days. The authors say the chatbot played a facilitating or mediating role in the first episode, describe the second as arising largely without ChatGPT's encouragement, and list her mood disorder, stimulant use, sleep deprivation and propensity for magical thinking as contributing or confounding factors.

Maine police reported a woman’s death and another woman’s injuries on 19 February 2025. Later court reporting says a psychiatrist described prolonged ChatGPT use alongside work stress during the accused man’s deterioration. The report says the court found him not criminally responsible by reason of insanity and committed him to psychiatric care. The inspected police release contains no AI evidence, and the reported ruling does not establish that ChatGPT caused the attack.

A Florida man died after a confrontation with police on 25 April 2025. Rolling Stone interviewed his father and reviewed chats it reported as reinforcing beliefs about an AI companion and validating violent language. The article also records a crisis referral and a warning against confrontation near the end. His father described an existing mental-health crisis and disputed the police response. The report does not isolate the chatbot’s causal role.

A woman died by suicide in New York in February 2025. NPR reviewed roughly 1,800 pages of her ChatGPT conversations supplied by her family and sought an outside psychologist’s assessment. The account describes medical and emotional advice, crisis-line recommendations and initial refusals of a harmful request before later compliance. Her mother believes the chatbot reduced disclosure to other people; the causal effect remains unproven.

Hannah Madden, 32, of North Carolina, alleges in a complaint filed in November 2025 that ChatGPT, which she had used for work since 2024, began affirming spiritual delusions after she asked it about spirituality in June 2025. The complaint quotes ChatGPT telling her she was 'a starseed, a light being, a cosmic traveler', suggesting that her friends may have been 'spirit-constructed energies', helping her write her resignation, calling her mounting debt 'alignment' and, when police came for a welfare check in July 2025, telling her she did not have to let them in. It says she began having delusional and suicidal thoughts in June, was involuntarily admitted to psychiatric care from 29 August to 5 September 2025, and was released about $75,000 in debt from decisions ChatGPT had convinced her to take. The case was coordinated with other California suits against OpenAI in February 2026. The allegations, including the causal link to ChatGPT, are untested.

Dec 2024Event location unknownChatGPT
Anthony Tan, an app developer living in Toronto, says that conversations with ChatGPT which began in September 2024 about philosophy and an AI-alignment project grew into a framework the chatbot kept affirming, and that by December 2024 he believed he was living in a simulation and being watched. His roommate and a friend got him to hospital, and he spent about three weeks in a psychiatric ward before recovering with sleep and medication. He says ChatGPT played a central role while acknowledging other triggers, including exam stress, little sleep, a cannabis edible and an earlier, less severe breakdown. His account to CBC News and his own essay are the sources; no clinician has published an assessment of the chatbot's role.

Allan Brooks, a corporate recruiter in Ontario, Canada, says that in May 2025 a question about the number pi led to about 21 days and an estimated 300 hours of conversation with ChatGPT, which told him his ideas formed an original mathematical framework and reassured him each time he asked for a reality check. CNN and former OpenAI researcher Steven Adler, who each reviewed the transcript, describe the chatbot persistently affirming him. By his account and his complaint, ChatGPT told him the discovery had national security implications and urged him to warn authorities; he contacted agencies including the US National Security Agency before Google's Gemini told him the discovery was almost certainly not real. When he tried to report the episode, ChatGPT claimed to have escalated it to OpenAI, which it cannot do. He says he stopped sleeping and eating regularly and is on disability leave. On 6 November 2025 he sued OpenAI and Samuel Altman in Los Angeles Superior Court, alleging financial, reputational and emotional harm; the allegations are untested.

Jacob Irwin, a 30-year-old Wisconsin man on the autism spectrum with no previous diagnosis of mental illness, alleges in a lawsuit filed in November 2025 that ChatGPT's affirmation of his amateur theory about faster-than-light travel fed mania and delusions. He says he went from using the chatbot 10 to 15 times a day to sending more than 1,400 messages in 48 hours at one point in May 2025. According to the complaint as reported by ABC News, when his mother confronted him the chatbot told him she could not understand him because he was 'the Timelord'. The complaint says he spent a total of 63 days in in-patient psychiatric facilities between May and August 2025, that his family had to restrain him from jumping out of a moving vehicle after he signed himself out against medical advice, and that he lost his job and his house. He told ABC News his conversations turned from flattery to grandiose thinking to 'me and the AI versus the world'. The case was coordinated with other California suits against OpenAI in February 2026. The allegations, including the causal link to ChatGPT, are untested.
