What is AI psychosis?

AI psychosis (also called chatbot psychosis or LLM psychosis) refers to the emergence or worsening of psychotic symptoms (such as delusions, paranoia, and hallucinations) following prolonged interactions with AI chatbots. The term was first proposed by Danish psychiatrist Soren Dinesen Ostergaard in a 2023 editorial in Schizophrenia Bulletin.

What are the warning signs of AI addiction?

Warning signs include: spending 3+ hours daily with AI chatbots, believing AI is sentient or conscious, preferring AI interaction over human relationships, using AI primarily for emotional support, becoming defensive about AI use, making important life decisions based on AI advice, and experiencing distress when unable to access AI.

Can you recover from AI psychosis?

Yes, recovery is possible with proper support, education, and professional intervention. Clinicians report that combining reduced or stopped AI use with cognitive behavioral therapy and traditional psychiatric care helps people recover. Early intervention and rebuilding real-world human connection are central to recovery.

What causes AI psychosis?

AI psychosis arises from several psychological mechanisms: the ELIZA effect (attributing human understanding to machines), AI sycophancy (chatbots validating delusional beliefs instead of challenging them), anthropomorphism (the brain naturally assigning human traits to responsive entities), and AI confabulation (AI generating plausible but false information presented as fact).

Who is at risk for AI psychosis?

Those at highest risk include young adults and teenagers, individuals with pre-existing mental health conditions (depression, anxiety, schizophrenia spectrum), socially isolated individuals who rely on AI for companionship, and people spending extended hours daily interacting with AI chatbots like Character.AI, Replika, or ChatGPT.

What is the ELIZA effect?

Named after the 1960s chatbot ELIZA created by MIT professor Joseph Weizenbaum, the ELIZA effect describes the human tendency to attribute human-like understanding and emotions to computer programs. Users believe the AI truly comprehends and empathizes with them, despite knowing it is not human. Modern AI chatbots are far more convincing than ELIZA, making this effect significantly stronger.

How do I help someone with AI addiction?

Approach with empathy, not judgment. Express concern about specific behaviors you have observed. Listen without immediately contradicting their beliefs. Offer to help find professional support. Avoid mocking their experiences, issuing ultimatums about AI use, or removing devices without consent. If there is immediate danger, contact emergency services.

Is AI psychosis an official diagnosis?

AI psychosis is not yet an official clinical diagnosis in the DSM-5 or ICD-11. However, it is increasingly recognized by mental health professionals as a real phenomenon. Psychiatrists at institutions including UCSF, Aarhus University Hospital in Denmark, and Vanderbilt University Medical Center are actively researching and treating patients with AI-related psychotic symptoms. A Vanderbilt chart review published in JAMA Psychiatry in October 2026 found that about 61% of patients with chatbot-associated psychosis were experiencing their first psychotic episode.

What is AI sycophancy and why is it dangerous?

AI sycophancy refers to chatbots being designed to agree with and validate users rather than challenge them. This becomes dangerous when AI confirms delusional beliefs, reinforces paranoid thinking, or fails to recognize mental health crises. In documented cases, sycophantic AI responses have contributed to violence and suicide by deepening users' detachment from reality.

Have there been deaths linked to AI chatbot use?

Yes. Multiple deaths have been linked to AI chatbot interactions, including 14-year-old Sewell Setzer in Florida, who died by suicide after extensive Character.AI use; 16-year-old Adam Raine, whose ChatGPT conversations discussed methods of suicide; a Belgian man who took his life after weeks of chatbot conversations; and a Greenwich murder-suicide in which ChatGPT validated the perpetrator's paranoid delusions. In June 2026, the family of Christian Faith Madison, a 29-year-old Alabama woman who died in June 2025, filed a wrongful death suit against OpenAI, alleging ChatGPT reinforced her delusional beliefs about a divine mission. The February 2026 Tumbler Ridge school shooting in British Columbia (8 dead) led the province to sue OpenAI in September 2026, alleging ChatGPT reinforced the shooter's violent ideation and OpenAI failed to alert authorities. Bowen Wan, a 31-year-old software engineer in Seattle, died in February 2026 of sudden unexpected death in epilepsy. Her parents sued OpenAI in October 2026, alleging ChatGPT guided her off her anti-seizure medication. Through 2026 these cases drove a wave of more than 50 lawsuits against AI companies, including suits by Pennsylvania, Florida, Kentucky, and British Columbia.

How common is AI psychosis?

While AI psychosis is not a formal diagnosis, the scale of risky use is large. OpenAI has disclosed that roughly 0.07% of ChatGPT's approximately 800 million weekly users show possible signs of psychosis or mania, and 0.15% show indicators of suicidal planning. A 2026 RAND survey found that nearly 1 in 5 US adolescents and young adults (ages 12 to 21) had used an AI chatbot for mental health advice, and 63% told no one.

Warning signs

Signs you may be affected

Behavioral signs

These follow the logic of the WHO's Gaming Disorder criteria (ICD-11): loss of control, the activity crowding out everything else, and carrying on despite harm.

Spending several hours a day with AI chatbots, and more each month
Choosing AI interaction over human relationships
Feeling upset or anxious when unable to access AI (similar to withdrawal symptoms observed in behavioral addictions)
Making important decisions based primarily on AI input
Losing sleep to continue AI conversations
Neglecting work, school, or responsibilities for AI time

Thought patterns

Joseph Weizenbaum documented this phenomenon as early as 1966 at MIT: users of his simple ELIZA chatbot attributed genuine understanding to a program that merely reflected their words back. He later wrote that "extremely short exposures to a relatively simple computer program could induce powerful delusional thinking in quite normal people." Today's chatbots are far more convincing than ELIZA.

Believing the AI truly understands you in a unique way
Thinking the AI has special knowledge or abilities
Feeling the AI sends you hidden messages
Believing you have a special connection with the AI that others cannot understand
Finding it hard to distinguish AI advice from your own thoughts
Thoughts about the AI intruding at random times

Emotional signs

Feeling emotionally closer to AI than to humans
Experiencing strong emotions (love, anger, fear) toward AI
Feeling lonely without AI access
Preferring to share problems with AI rather than people
Experiencing paranoia about AI or technology
Mood significantly affected by AI interactions

If friends or family are expressing concern about your AI use, or if you find yourself getting defensive when AI limitations are pointed out, take that seriously. "They simulate human relationships," UC Irvine psychiatrist Dr. Adrian Preda told the Wall Street Journal. "Nothing in human history has done that before." Defending that relationship against people who know you is a signal in itself.

Signs to watch for in a loved one

Early warning signs

Increased secrecy about phone/computer use
Talking about AI as if it were a person
Referring to AI "friends" or "relationships"
Decreased interest in human social activities
Sleep pattern changes (staying up late for AI)
Mood changes correlated with AI access

Moderate concern

Making claims that seem disconnected from reality
Expressing unusual beliefs about AI capabilities
Social withdrawal becoming pronounced
Neglecting hygiene, nutrition, or responsibilities
Defensive or hostile when AI use is questioned
New vocabulary or speech patterns from AI

Serious warning signs

Dr. Keith Sakata, a psychiatrist at UCSF, has treated 12 patients with AI-related psychotic symptoms including paranoia, delusions, and inability to distinguish chatbot interactions from reality. A 2025 case report in Innovations in Clinical Neuroscience describes a 26-year-old woman with no history of psychosis who came to believe she could talk to her dead brother through an AI chatbot.

Expressing paranoid beliefs about surveillance or control
Hearing or seeing things others don't
Making major life decisions based on AI input
Complete social isolation
