The cause of alcoholic hallucinosis is unclear. The symptoms included delirium, hallucinosis, convulsions and fever. Posterior thalamic lesions were also found to be linked to peduncular hallucinosis by De Morsier. Typically, alcoholic hallucinosis has a sudden onset. Delirium tremens (DTs) do not appear suddenly, unlike alcoholic hallucinosis. Alcoholic hallucinosis is a much less serious diagnosis than delirium tremens. Organic Hallucinosis is the fourth studio album by Polish death metal band Decapitated. Peduncular hallucinosis therefore might emanate from disturbances in distal portions of the visual system.
