[Poisoning with spotted and red mushrooms--pathogenesis, symptoms, treatment]

Amanita pantherina and Amanita muscaria are commonly occurring mushrooms in Polish forests. They contain ibotenic acid and muscimol: the substances reacting with neurotransmitter receptors in central nervous system. The ingestion of these mushrooms produces a distinctive syndrome consisting of alternating phases of drowsiness and agitation with hallucinations, and sometimes with convulsions. The diagnosis of Amanita pantherina or Amanita muscaria poisoning is established by means of mycologic investigation of gastric lavage. The treatment is only symptomatic, and the prognosis is usually good.
