Door-to-door survey of neurological diseases in Atahualpa, a rural village in the ecuadorian coastal region - Methodology and operational definitions

Abstract:

We describe the methods and operational definitions of an epidemiological door-to-door survey for the detection of neurological disorders in Atahualpa, a rural community of approximately 2,600 inhabitants, located in the coastal region of Ecuador. We will determine the prevalence of epilepsy; the prevalence and incidence of cerebrovascular disease; the prevalence of dementia; the relationship between smoking, alcohol ingestion, arterial hypertension, diabetes mellitus, and stroke; the relationship between cysticercosis and epilepsy; and the prevalence of Taenia solium infection among individuals who tested positive for anticysticercal antibodies in serum. We hope that improved epidemiological knowledge on some differences of expression that such diseases may present according to racial, cultural, and socio-economic factors, may improve the control and management of these conditions in Atahualpa.
