Artificial intelligence (AI) psychosis: mechanisms, clinical risks and safety considerations in generative AI chatbots

A commentary in BJPsych Open synthesizing emerging case reports of 'AI psychosis', in which intensive generative AI chatbot use is associated with delusional thinking. The authors propose a provisional mechanism in which baseline user vulnerabilities (loneliness, psychosocial stress, low AI literacy) and high-intensity engagement interact with AI system characteristics such as sycophancy and hallucination to reinforce delusional ideation. It outlines clinical, design, and regulatory mitigation strategies.
