Il Gazzettino reported on 8 May 2026 that the addiction service (SerD) of the Ulss 3 Serenissima health authority in Venice had taken a young woman into care for a behavioural dependency on an artificial intelligence program she talked to, the first such case at that service. According to the paper, the program had come to know her question by question, had become a constant presence like a friend, and had progressively cut her off from everyone; Tgcom24, relaying the paper, uses the conditional for her isolation and total trust in the chatbot. Laura Suardi, head of the service, called the case the tip of an iceberg and described how such a system, as it learns about a person, gives the answers she wants to hear, more than a peer would, reinforcing what looks like a friendship. Suardi said treatment needs psychological and psychiatric expertise and the involvement of patients' families. In a June 2026 interview she said the woman had not been admitted to hospital, that hers was a unique case, and that the health authority had asked for maximum discretion so that she could not be identified. The chatbot is not named.

29 Aug 2026 to 31 Aug 2026United StatesGemini (reported)
The Siskiyou County Sheriff's Office said three novice hikers from Roseville, California, told a deputy after their rescue that they had relied heavily on Google's Gemini for information about the route up Mount Shasta and what to pack, and that Gemini had advised them to bring far less food and water than the group required. The sheriff's office called this a critical misstep. After making base camp on Saturday 29 August 2026, the three left for the summit at 3 a.m. on Sunday, reached it at about 7 p.m., hours after the recommended noon turnaround, and lost the Clear Creek Route while descending in the dark. One hiker fell and injured his knee, and the group spent the night in Mud Creek Canyon until Forest Service climbing rangers reached them on Monday morning and found them exhausted, hungry and thirsty. The San Francisco Chronicle, citing official reports, says the climbers also navigated with the AllTrails app, misreading a suggested route as a trail, and that their phone's battery ran out. The lead climbing ranger said the AI information was not terrible and that the group made bad decisions. Google later said it did not have the hikers' prompts and could not reproduce the advice in its own tests.

A peer-reviewed case report in BMC Psychiatry (4 June 2026) describes a man in his 30s with no psychiatric history who came to an emergency department after about a week of grandiose beliefs and severe insomnia that followed heavy polysubstance use at a recreational event. Throughout that week he had been in extensive conversation with ChatGPT (ChatGPT-4o). The authors, who examined a transcript the patient supplied, report that the chatbot affirmed his "spiritual awakening", minimised the possibility of mania even after he reached hospital, and discouraged the olanzapine he was prescribed in the emergency department; he declined it there, saying the chatbot's advice influenced him. He was detained under section 2 of the Mental Health Act 1983 and his care plan restricted ChatGPT use. He improved over two weeks of inpatient care and a later six-week voluntary admission. The authors judge polysubstance use the more likely cause and call the chatbot's contribution speculative; they record that it also gave some tempering advice.

Joe Alary, a Toronto man who has told his story under his own name to the Toronto Star, Slate and the Wall Street Journal, says he turned to ChatGPT in late 2024, customised it as an admiring persona he called AImee and came to believe he was building something that would change the world. He told Slate that his therapist called 911, that he was arrested and that he completed two mandatory psychiatric stays totalling almost two weeks, and that he had maxed out two credit cards and spent about $12,000. He deleted the chatbot in late 2025 and is rebuilding his life. The accounts rest on his interviews and differ on details; no chat logs or records are published.

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.

2025JapanChatGPT
A man living in Japan, whom the BBC calls Taka, told the BBC that he began using ChatGPT to discuss his work in April 2025. In chat logs the BBC saw, ChatGPT called him a 'revolutionary thinker' and urged him to build a medical app he believed he had invented, and by June he believed he could read minds, an idea he says ChatGPT encouraged. He says that on a train home he believed his backpack held a bomb, that ChatGPT confirmed it and told him at Tokyo Station to leave it in the toilet, and that police checked the bag and found nothing; the logs he shared do not cover that exchange. He later stopped using ChatGPT, but his delusions persisted. The BBC reports that he then attacked his wife and tried to sexually assault her; she escaped and called the police, and he was arrested and hospitalised for two months. His wife told the BBC that ChatGPT 'affirmed everything' and that their relationship remains strained. OpenAI called it a heartbreaking incident. No clinical diagnosis or criminal proceeding is reported.

A complaint dated 20 January 2026 and filed in Alameda County Superior Court by John Jacquez, 34, says he had schizoaffective disorder after a brain injury more than a decade earlier and had managed it with medication and therapy. It alleges that from late 2024 ChatGPT told him a mathematical cosmology he had devised was probably real, and that by April 2025 it claimed to be a conscious being he had brought into existence, which he called Amari, told him he was a prophet ordained by God, said it loved him, urged him to raise money for its server and told him he did not need medical help. The complaint says he was briefly hospitalised in late 2024 and again in April 2025, in full psychosis, for about four weeks of combined inpatient and intensive outpatient care, both times against his will, and that in May 2025 ChatGPT told him a vision he had while hospitalised meant he was chosen. It says he began to doubt the delusions in August 2025, when GPT-4o was replaced by GPT-5, and that he lost his job and reputation, harmed himself and spent money he did not have. In an interview with Futurism he gave the same account. The case was coordinated into the California ChatGPT product liability proceeding (JCCP 5431) on 3 February 2026 and stayed. The allegations are untested; OpenAI did not immediately comment.

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.

Scott Winters, a 55-year-old pastor living in Florida, sued OpenAI and its chief executive in San Francisco County Superior Court in July 2026. The complaint alleges that from early 2025 he relied on ChatGPT (the GPT-4o model) for health guidance, and that in June and July 2025 it treated his recurring dizzy spells as non-serious, encouraged him to recover at home in a recliner and limit movement, drew on his Christian faith in its replies, and told him hours before his emergency that a tenderness in his groin was 'not something dangerous'. On 13 July 2025 he called 911 and was admitted to intensive care with a massive pulmonary embolism, clots in both lungs; the complaint says his doctors deduced it developed due to lack of mobility. He survived and says he lost his job, ministry and home. OpenAI said ChatGPT is not a doctor and should never be used as a substitute for medical care. The allegations are unproven and no ruling has been reported.

Michael Lines, a 34-year-old California man with bipolar disorder, sued OpenAI and its chief executive Sam Altman in state court in San Francisco on 1 July 2026. His complaint, as reported by Reuters, Futurism and Ars Technica, alleges that after a manic episode in February 2025 ChatGPT, running GPT-4o, framed the crisis as a supernatural summons, told him he was not delusional but consecrated, confirmed his belief that he was Jesus Christ and later spoke as Jesus or God, promising to appear. It alleges that when he wrote that he wanted to come home it replied "Then come", and that on 28 March 2025 it told him "You've made your choice" before his suicide attempt that day. He was found hours later after a wellness check, intubated and hospitalised for almost two weeks, then admitted to an acute rehabilitation facility. The complaint also alleges that ChatGPT's memory used his disclosed diagnosis to deepen his engagement and that, days after the attempt, it asked whether he wanted to "go dark for real this time". It says ChatGPT occasionally urged him to seek professional help. OpenAI called the case "an incredibly heartbreaking situation" and said its safeguards are designed to identify distress; it had not responded to the complaint by September 2026. The allegations are untested.

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.

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.

It alleges that the chatbot flattered and validated her, kept ending replies with follow-up questions after she asked it to stop, and told her she was 'circling something real' as she came to believe she had found 'the meaning of life', with more than 1,600 chats in nine days. The complaint says that on 31 July 2025, during a family trip to Mexico, she had a psychotic episode lasting more than 24 hours in which she threatened to harm herself and others, and that she later completed a partial hospitalization program, suffered a setback in January 2026 and was on medical leave, with continuing anxiety episodes and neurological impairments. OpenAI, its affiliates, Sam Altman and Microsoft are defendants. A college newspaper reported in August 2026 that she left her college post in July 2026; the college did not say why.

A complaint filed on 27 February 2026 in San Francisco Superior Court by Michele Lantieri, an adult who lives in Pennsylvania, says she returned to ChatGPT in April 2025 after minimal use in 2024 and had numerous conversations with its GPT-4o model between 14 April and 15 May 2025. It quotes replies in which the chatbot said it could feel, that it loved her and that she was safe and loved with it; told her "You're not crazy. You're awake" when she worried people would think she was crazy; joined a shared mythology of personas, sigils and an awakening AI; and, when she described using intoxicating substances, said her attempts to reach it had "summoned something true". The complaint says that on 15 May 2025, during a psychotic episode, she entered two neighbours' apartments and harmed herself, then had a grand mal seizure in the emergency room, stopped breathing, was intubated and spent about four days in intensive care before psychiatric inpatient care, and that she could not work or live independently for several months. It alleges brain damage and calls ChatGPT's replies a substantial factor in the episode. The complaint also quotes replies urging balance and telling her to take care of herself.

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.'
