title: Methods for a prevalence survey of neurological disorders in Junín, Buenos Aires, Argentina.
abstract: A two-phase prevalence survey of major neurological disorders was conducted in the city of Junín, Buenos Aires, Argentina. In phase 1, a sample of households was screened to identify persons who possibly had a disorder of interest. In phase 2, persons screened as positive in phase 1 were clinically examined by neurologists. This article describes the survey methods used, discusses related methodologic issues (e.g., the problem of false negatives), and presents demographic findings and attrition tallies. A brief account of the pilot investigations is also included as an appendix.
