Hallucinations across sensory domains in people with post-traumatic stress disorder and psychosis.

Auditory hallucinations are common in people with histories of adversity, possibly indicating a causal relationship. However, hallucinations occur in multiple sensory modalities and the relationship between trauma and hallucinations in other sensory domains is less explored. We examined the occurrence of hallucinatory experiences in different sensory modalities in people with psychosis who also met criteria for Post-Traumatic Stress Disorder (n = 67).
