A 48-year-old man without prior medical history developed a paranoid psychosis with visual and auditory hallucinations that lasted five days after eating Amanita muscaria mushrooms, which he mistook for edible A. caesarea. The typical duration of symptoms from this mushroom is under 24 hours, but in this case psychosis appeared 18 hours after ingestion and persisted for five days before gradually resolving. One year later the man had no symptoms of psychiatric disease and was not undergoing therapy.
