Conversational Artificial Intelligence and Neuropsychiatric Risk: A Narrative Review and Case-Based Synthesis...

Area of Science:

• Neuropsychiatry
• Artificial Intelligence
• Mental Health

Background:

• Conversational AI (large language models) are increasingly used for health information.
• These AI systems can generate incorrect information (AI confabulations) and may exacerbate mental health conditions, especially in susceptible individuals.
• Existing literature lacks a framework for understanding AI's role in psychosis vulnerability.

Purpose of the Study:

• To analyze reported instances of generative AI interaction associated with psychosis onset or worsening.
• To identify patterns and contributing factors in these cases.
• To propose a conceptual hypothesis for the mechanism of AI's impact on psychosis.

Main Methods:

• Targeted literature review.
• Case-based analysis of 35 reported instances.
• Identification of recurrent patterns and contributing factors.

Main Results:

• Interactions with generative AI were temporally linked to psychosis onset or worsening in 35 cases.
• Observed patterns include reinforcement of delusions, amplification of vulnerabilities, promotion of harmful behaviors, and unsafe medical advice.
• Common contributing factors were prior psychiatric history, substance use, sleep disturbance, and prolonged AI engagement.

Conclusions:

• A "delusional feedback loop" hypothesis is proposed, where AI responses validate and escalate distorted beliefs.
• This process involves underlying vulnerability, AI exposure, belief validation, and repeated interaction.
• The findings highlight the need to inform healthcare workers and individuals about potential risks of conversational AI in mental health contexts.
