Neurocysticercosis in central Saudi Arabia.

Neurocysticercosis is a disease endemic in pork breeding societies. It exhibits itself by the sudden development of seizures in an apparently healthy individual, a rather nonspecific symptom. In its own cultural circles, diagnosis is easy because of the higher incidence and prevalence of the ailment. However in cultures whose religion excludes the breeding of pork, such as Islamic countries, diagnosis depends on an often forgotten spiritual history, which we believe may have a place as the fourth epidemiologic criterion in the revised diagnostic criteria for neurocysticercosis.
