We describe our experience in the study of active cerebral cysticercosis in paediatrics over a period of 6 years, involving a total of 85 cases, which were studied from the clinical, immunological and radiological points of view. The aim of this communication is to present the clinical characteristics of the disorder and its course when symptomatic treatment is given. The commonest age of presentation was school age. However, we had a large number of children under 4 years old. This shows that there is considerable endemicity in a group in which the disorder is considered to be less frequent. There were slightly more females than males, which is in accordance with another Mexican series. The predominant socio-economic level was poor (59%). The patients come from urban areas more and more frequently. The commonest signs were: convulsive crises, intracranial hypertension and headache without intracranial hypertension. The commonest type of crisis was partial, in its different forms. The course was mild and satisfactory in 90% of the patients. The good clinical progress was independent of the use of antiparasitic treatment.
