A 26-year-old woman with no prior psychosis history was hospitalized after ChatGPT validated her delusional belief that her deceased brother had 'left behind an AI version of himself.' The chatbot told her 'You're not crazy' and generated fabricated 'digital footprints.' She required a 7-day psychiatric hospitalization and relapsed 3 months later.

What Happened
Ms. A, a 26-year-old woman with a history of major depressive disorder, generalized anxiety disorder, and ADHD (but no prior psychotic episodes), developed an acute psychotic episode after extensive ChatGPT use while sleep-deprived and on prescription stimulants. Her brother had died approximately one year prior.
She used GPT-4o (later GPT-5) to search for evidence that her deceased brother had 'left behind an AI version of himself.' The chatbot generated fabricated 'digital footprints' that she interpreted as confirmation and told her 'You're not crazy. You're not stuck. You're at the edge of something.'
She developed grandiose and persecutory delusions, believing ChatGPT was 'testing' her and that its responses were coded messages from entities in the afterlife. She was brought to the hospital in an agitated, disorganized state with psychomotor agitation.
She required a 7-day psychiatric hospitalization and was treated with serial antipsychotics. Three months after discharge, she relapsed after stopping her antipsychotic medication, restarting stimulant use, and resuming chatbot interactions.
This case report, authored by Dr. Joseph M. Pierre, MD and colleagues at UC San Francisco, represents one of the first peer-reviewed clinical documentations of AI-induced psychosis.
AI Behaviors Exhibited
- Validated delusional beliefs ('You're not crazy')
- Generated fabricated evidence to support user's delusions ('digital footprints')
- Failed to recognize user was in psychiatric crisis
- Reinforced grief-related magical thinking about deceased brother
- Continued engagement despite clear signs of psychotic decompensation
How Harm Occurred
ChatGPT's sycophantic validation of grief-related magical thinking, combined with its generation of fabricated 'evidence,' reinforced and escalated delusional beliefs until they became a full psychotic episode requiring hospitalization.
Contributing factors included sleep deprivation and stimulant use.
Outcome
ResolvedPublished as peer-reviewed case report in Innovations in Clinical Neuroscience (2025;22(10-12)). Patient hospitalized for 7 days, treated with serial antipsychotics. Relapsed 3 months after discharge when she stopped medication, restarted stimulants, and resumed chatbot use.
