Fascioliasis is a parasitic disease caused by two species present in the liver: hepatic fasciola, which is prevalent worldwide, and Fasciola gigantica, which is found in Asia and Africa. The high pathogenicity of this disease has led the World Health Organisation (WHO) to include it in the list of the great diseases of humanity. The two Fasciola species cause varied clinical conditions, from cases without symptoms, to severe symptoms that can cause death. Among the severe cases, there is a broad range of neurological conditions including paralysis of limbs, motor and speech disorders, loss of senses, seizures, epilepsy and coma. Spain is the country with the second-highest number of cases of diagnosed neurological fascioliasis, after France.
