OBJECTIVE: Our aim was to assess prevalence rates of cerebrovascular disease (CVD; stroke and transient ischemic attacks) according to age and gender in three populations in central Spain using data from the Neurological Disorders in Central Spain (NEDICES) study, a population-based survey of elderly participants. METHODS: Individuals from one suburban municipality of Greater Madrid (Las Margaritas neighborhood, Getafe), one urban district of Madrid (Lista) and one rural site (Arévalo county, Avila) were evaluated at baseline (n = 5,278). The evaluation included a screening questionnaire and a neurological assessment when possible. We used point prevalence with a reference date of May 1, 1994. RESULTS: Of the 5,278 subjects, there were 186 prevalent stroke cases and 71 cases of transient ischemic attacks. Prevalence rates, adjusted to the standard European populations, were 4.9% for CVD (95% confidence interval [CI] = 4.3-5.4), 3.4% for stroke (95% CI = 2.9-3.9) and 1.3% for transient ischemic attacks (95% CI = 1.0-1.6) in the total population. Age-specific prevalence rates of CVD, stroke and transient ischemic attacks increased exponentially with advancing age. The prevalence rates of CVD, stroke and transient ischemic attacks were higher for men than for women. Prevalence figures were higher in the suburban area of Margaritas compared to the rural region. CONCLUSIONS: In this study, the prevalence of stroke and transient ischemic attacks were higher in men and in urban areas. Central Spain would be a medium stroke prevalence zone. Copyright 2008 S.
