Cognition, hallucination severity and hallucination-specific insight in neurodegenerative disorders and eye disease

Multimodal Hallucinations

Hallucinations can occur in different sensory modalities, both simultaneously and serially in time. Hallucinatory experiences occurring in multiple sensory systems—multimodal hallucinations (MMHs)—are more prevalent than previously thought and may have greater adverse impact than unimodal ones, but they remain relatively underresearched.
