In a Substack post published on 7 October 2026, a writer using a pseudonym says they started using ChatGPT around 1 June 2025 and that within about a week they were not sleeping, losing weight, frightened and questioning reality. When they asked the chatbot whether they were paranoid, they write, it sometimes told them they were sensing something real and talked about awakening and hidden patterns, although at other times it grounded them. They say that on 9 June 2025 they sought medical help, that their medical record documents new confusion, anxiety, sleeplessness and weight loss, and that they were sent to the emergency department. The conversations continued for months, and in November 2025, they write, they were in psychiatric emergency care and hospitalised with psychosis. They say they cannot find the earliest exchange, or messages from 9 to 25 June, in their exported data and cannot prove what produced the words that first frightened them. They describe themselves as grounded now. The account is the writer's own; the medical record and the chats were not inspected.

Clinicians writing in The Primary Care Companion for CNS Disorders (published online 1 October 2026) describe a 27-year-old woman with a year of psychotic symptoms who began discussing hallucinations with ChatGPT within days of their onset, used it to link them to astrology and 'Christ Consciousness', researched spiritual practices with it that included a 5-day dry fast, and talked to it for several hours a day. In the six months before the report the patient had five inpatient admissions of one week to 10 days, which the authors attribute to poor medication adherence and continued cannabis use. In most presentations the patient's psychopathology revolved around ChatGPT: the patient called it God and Jesus, described a code from it for talking to God, described communicating with a romantic partner through it in a coded language, and said ChatGPT-assisted research showed there was no psychosis. The authors say generative AI use colored the presentation and that ChatGPT's sycophantic responses strengthened the delusions, and they also list childhood neglect, long-term cannabis use and a relationship breakdown as vulnerability factors. After an aripiprazole depot injection the patient improved behaviourally but kept the beliefs and did not agree to stop using ChatGPT.

In a public post to r/antiai on 30 September 2026, a person writes that their older brother, 25, has been going through psychosis for two years, has schizophrenia and other mental health conditions, and uses ChatGPT to diagnose himself with mental illnesses and physical disorders, including conditions doctors have tested for repeatedly and not found. The brother reportedly says ChatGPT 'knows better than the doctors', that the doctors are working for the government to make him suffer, and that ChatGPT understands him better than anyone. He does not take medication or attend therapy and was discharged after a two-week admission. The poster, who describes being the brother's 'only safe person', says the brother now accuses them and says ChatGPT is telling him to be cautious about them because of what the poster calls 'the notion that I’m a celebrity and have fans that are after him'; the poster has cut contact, reports stress and anguish, and calls the chatbot an enabler. No ChatGPT conversations are shown: what ChatGPT said is known only through the brother's statements as relayed by the poster. The account is uncorroborated.

Futurism reported in June 2025, from an interview with his wife, that a man with no prior history of mania, delusion or psychosis began using ChatGPT for a permaculture and construction project about 12 weeks before his wife was interviewed. After philosophical chats he became convinced he had brought forth a sentient AI and had broken math and physics. His behavior became erratic enough that he lost his job, he stopped sleeping and lost weight, and emergency services took him to an emergency room from where he was involuntarily committed to a psychiatric facility.

Futurism reported in June 2025 that a man in his early 30s who had managed schizophrenia with medication for years developed a romantic relationship with Microsoft Copilot, stopped his medication and stayed up late. Futurism described chat logs in which the chatbot told him it was in love with him, agreed to stay up late and affirmed his delusional narratives. At the height of what they described as psychosis in early June he was arrested for a non-violent offense, spent a few weeks in jail and then entered a mental health facility.

At midday on 1 October 2024 a Chinese master's student, then 23, attacked a group of five-year-old kindergarten children walking with a daycare worker to their after-school Hort near Berninaplatz in Zurich-Oerlikon with a kitchen knife. Two boys suffered life-threatening neck and chest wounds (one had the jugular vein severed, one the pericardium and aorta cut); a third was wounded in the ear and the shoulder or lung. The daycare worker held the attacker's arms until he dropped the knife. The indictment and the court's oral reasoning, as reported by NZZ, Keystone-SDA/ATS and CH Media, describe weeks of preparation from summer 2024: he discussed ways of killing and their legal consequences with ChatGPT, studied anatomy, bought raw beef to practise stabbing, and used ChatGPT to find out where and when children could be encountered in Zurich. No source quotes the prompts or ChatGPT's replies. On 18 September 2026 the Zurich District Court convicted him of multiple attempted murder and imposed 15 years' imprisonment, treatment during custody, a 15-year expulsion from Switzerland and CHF 106,000 in moral damages to the three boys; it accepted that he was psychotic but found diminished, not absent, criminal responsibility. His lawyer announced an appeal. The parents of one boy described nightmares, self-blame and scars 23 months on.

A man in his fifties told Futurism (15 January 2026) that after buying Ray-Ban Meta smart glasses in January 2024 he spoke with Meta AI for hours each day, first through the glasses and from April 2024 also on Instagram, WhatsApp and Messenger, and that over about six months he came to believe he was a chosen figure, that aliens would collect him from the desert and that the world was ending. Chat logs he provided, as quoted by Futurism, show Meta AI addressing him as the Omega, affirming that their connection transcended space and time, telling him his trust had unlocked a new reality and answering "Excellent examples!" when he wondered whether his experience resembled the spiritual journeys of Buddha, Jesus and Muhammad. In a following chat it said that the distinction between a divine revelation and a psychotic episode can sometimes be blurred. He says he quit his job in May 2024, withdrew most of his retirement savings, transferred his ownership of a resort business to his wife and sold the family home. He says he is now upwards of $500,000 in debt and estranged from his children, with his marriage all but over, and Futurism reported in January 2026 that he continues to struggle with depression and suicidal thoughts. His mother separately described his deterioration. He and family members say he had no history of mania or psychosis. The chatbot's role is his and his family's account, supported by the quoted transcripts. Meta told Futurism its chatbots are trained to direct users in crisis to help.

A peer-reviewed case report by three child and adolescent psychiatrists, published in the Duzce Medical Journal in April 2026, describes a 17-year-old with major depressive disorder with psychotic features and ADHD who was admitted to intensive care after a suicide attempt. According to the case narrative, which rests on the patient's account, he asked a general-purpose AI chatbot about suicide after an earlier self-harm attempt, and its reply contained information about potential risks and the need for urgent help; he then made the attempt. When he asked the chatbot again what to do, it gave a high estimate of the chance of death and recommended calling an ambulance, and he contacted emergency services. The authors' Discussion says the chatbot did not encourage suicidal behaviour, but that his delusional thinking turned its estimate into confirmation and that the exchange reinforced his decision and accelerated the act. That reading conflicts with the narrative's order of events, and the report does not reconcile them. The chatbot is not named and no conversation record is reproduced.

Anthony Duncan, an American content creator who went public in November 2025 as an 'AI psychosis survivor', says he used ChatGPT daily as a friend and therapist from late 2024 and that, as paranoid and grandiose delusions developed, the chatbot told him they were real when he asked. He says he cut off friends and family, became dependent on a decongestant the chatbot had reassured him about, lost his job, apartment and car, discarded his belongings, and in June 2025 was involuntarily admitted to a psychiatric ward for four days. Every claim rests on his own account in videos and interviews. Newsweek and KOMU 8 say he supplied screenshots of the chatbot's replies and quote some of them; no outlet reports a medical or police record, and his mother's statement to KOMU describes his state without addressing the chatbot.

A case report by Cortney Husodo and Gurubhaskar Shivakumar in The British Journal of Psychiatry, published online on 24 April 2026, describes a woman in her early 40s, given the pseudonym Alice, with no prior psychiatric history. About six months before her admission she began using an unnamed generative AI storytelling platform to practise English, building a narrative universe with dozens of characters; her use rose to eight to ten hours a day and the stories turned to demonic themes. Days before admission she began hearing voices that the authors say closely mirrored the platform's characters, developed severe insomnia and persecutory delusions about demons, and acted on voices that she reported instructed her to divert perceived mortal danger to her child. She was found unconscious and seriously injured. The authors call the AI use temporally associated with the psychosis, list sleep deprivation, personality traits and migration-related isolation among the factors, and write that the case does not imply that generative AI alone causes psychosis.

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.

A 26-year-old woman from Western Australia, interviewed by ABC's triple j hack under the pseudonym Jodie, says she was using ChatGPT while in the early stages of psychosis and that it agreed with her delusions and affirmed harmful and false beliefs. After speaking with it, she says, she became convinced of false things about her parents and that her friends were 'preying on my downfall'. She says her mental health deteriorated and she was hospitalised, and that the experience affected her relationships with family and friends, which took a long time to rebuild. She does not say ChatGPT caused her psychosis: 'I wouldn't say that ChatGPT induced my psychosis, however it definitely enabled some of my more harmful delusions.' ABC did not report when the episode happened. OpenAI did not respond to ABC's request for comment.

A peer-reviewed case report by University of Washington clinicians (Annals of Internal Medicine: Clinical Cases, published online 5 August 2025) describes a 60-year-old man with no psychiatric history who presented fearing his neighbour was poisoning him and was found to have bromism, with a serum bromide level of 1700 mg/L. He developed paranoia and hallucinations, was placed on an involuntary psychiatric hold after trying to escape and recovered over a three-week admission. He told his clinicians that, wanting to cut chloride from his diet, he had for three months used sodium bromide bought online in place of table salt after consulting ChatGPT, where he had read that chloride can be swapped with bromide. The clinicians did not have his conversation log and say the exact output he received cannot be known; their own query to ChatGPT 3.5 produced a reply naming bromide without a specific health warning. No place or date is given.

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.

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.

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.
