[Neurological manifestations of fish, mollusk and shellfish poisoning].

Sea-food poisoning is observed in several areas of the world. Intoxication results from ingestion of fresh fish, mollusks, or shellfish contaminated by toxins produced by microorganisms (dinoflagellates). Neurological manifestations are sometimes associated with signs and may be life-threatening. We describe here the principle toxins, their geographic distribution, clinical manifestations, therapeutic management, and possible prevention measures.
