Three-stage process to identify persons with active epilepsy. In the first stage, all individuals of the selected households were screened for epilepsy by non-medical field workers. In the second and third stage, suspected cases of epilepsy were examined by non-specialist medical doctors, and by a neurologist, respectively. Those suspected cases of epilepsy who were not seen by the neurologist, were considered to be ‘true’ cases of epilepsy if they had at least three positive answers on the epilepsy screening questionnaire or had previously been told by a doctor to have epilepsy (review and consensus)
