Abstract

Multisensory hallucinations—perceptions occurring across multiple sensory modalities without external stimuli—are increasingly recognized as a significant component of psychosis. This study investigates the prevalence and associated risk factors of multisensory hallucinations in populations at risk of transitioning to psychosis. Using a cohort of individuals identified as at high risk due to genetic, psychological, and environmental factors, we employed a combination of self-report measures and clinical assessments to gauge the occurrence of these hallucinations. Our findings reveal a notable prevalence of multisensory hallucinations in this at-risk group, with specific risk factors, including genetic predispositions and early life stressors, correlating with increased incidence. These results underscore the importance of early detection and intervention strategies targeting multisensory experiences as potential predictors of psychosis progression
