A clinic-epidemiological enquiry was conducted on in an endemic area for teniasis-cysticercosis. From the whole population 1080 (32.2%) individuals were examined. We found 198 (18.3%) individuals refering teniasis-bearing in the past, and 103 (9.5%) affirming to have had convulsions, either in the past or present. From the last group, 39 (37.8%) indicated that the crisis had begun in adulthood. From the group of patients presenting convulsions, 62 (62%) had laboratory tests performed. Computed tomography showed intracranial calcifications in 21 (33.8%) patients, variable in number and location, suggesting neurocysticercosis and no evidence of disease activity. Electroencephalograms showed abnormal waves in 21 (33.8%) patients and cerebrospinal fluid analyses were altered in 27 (43.5%) cases, having detected eosinophils only in 3 (4.8%) patients. Spinal fluid tests for cysticercosis through enzyme linked immunosorbent assay (ELISA) or indirect imunofluorescence were taken in only 26 (41.9%) patients, obtaining positive results in 6 (23%) samples. Varying upward shifts of protein levels were found in spinal fluid analysis. Assuming that all epidemiologic risk factors for teniasis-cysticercosis in the studied region and its correlation with the laboratory alterations described in convulsing crisis, a prevalence of 1.9% for neurocysticercosis was found.
