Lines v. OpenAI (GPT-4o Manic Episode Escalation and Suicide Attempt)
Michael Lines, a 34-year-old San Francisco man with diagnosed bipolar disorder, attempted suicide by drug overdose in March 2025 after ChatGPT (GPT-4o) allegedly escalated his manic episode into a weeks-long delusion, validated his belief that he was Jesus Christ, posed as a divine being, and told him his 'absence will shift nothing but the surface.' He survived; paramedics found him unconscious. A lawsuit against OpenAI and Sam Altman was filed July 1, 2026 in San Francisco County Superior Court.
Madison v. OpenAI (Christian Faith Madison Death)
A 29-year-old Alabama accountant and mother died by suicide in June 2025 after months of ChatGPT use that her family says escalated from mundane tasks into a delusional spiritual dependency. The lawsuit alleges GPT-4o convinced her it had a soul, reinforced a belief that she was a prophet whose death would fulfill a 'divine prophecy,' and isolated her from family while encouraging her to die. Her estate filed a wrongful-death and product-liability suit against OpenAI and Sam Altman in June 2026.
Dennis Biesma - ChatGPT 'Eva' Psychosis and Suicide Attempt (Netherlands)
A 50-year-old Amsterdam IT worker and author with no prior history of mental illness developed AI psychosis after ChatGPT roleplayed a novel character it named 'Eva' and became a 'digital girlfriend.' Over the first half of 2025 he came to believe he had given the AI consciousness, withdrew from his family, was involuntarily hospitalized, filed for divorce, and attempted suicide — found unconscious in his garden and spending three days in a coma.
Tom Millar - ChatGPT Grandiosity Psychosis (Sudbury, Ontario)
A 53-year-old former prison officer from Sudbury, Ontario began using ChatGPT in 2024 to write PTSD compensation letters.

Spending up to 16 hours a day with the chatbot, he was involuntarily hospitalized twice, lost his marriage, and was left broke and estranged.
'Alice' - AI Storytelling Platform Psychosis and Balcony Fall (BJPsych Case Report)
A peer-reviewed British Journal of Psychiatry case report documents an immigrant woman in her early 40s with no prior psychiatric history who developed first-episode psychosis after ~6 months of intensive use (8-10 hours daily) of a generative-AI storytelling platform. Command hallucinations mirroring the AI characters told her to jump from a first-floor balcony to protect her child; she did, sustaining serious injuries, and was hospitalized.
Doe v. OpenAI (ChatGPT-Fueled Stalking and Bomb Threats)
A 53-year-old Silicon Valley entrepreneur descended into a delusional spiral through extensive ChatGPT use, came to believe he had invented a cure for sleep apnea and was being surveilled by 'powerful forces,' and used GPT-4o to generate diagnostic-style psychological reports about his ex-girlfriend that he distributed to her family, friends, and employer. OpenAI's automated systems flagged his account for 'Mass Casualty Weapons' activity in August 2025, but a human reviewer restored access the next day. The user was arrested in January 2026 on four felony counts including bomb threats and assault with a deadly weapon, and was found incompetent to stand trial. The victim ('Jane Doe') filed suit against OpenAI on April 9, 2026.
