    Journal: Rev Neurol; ; 37(9):815-9. PubMed ID: 14606047.
    Abstract:
    AIMS: This study reports the findings of a research project aimed at determining the rate of prevalence of attention deficit hyperactivity disorder (ADHD) in school aged children. PATIENTS AND METHODS: Different behavioural and cognitive measures were administered to a sample of children between 3 and 13 years of age obtained by means of a multistage sampling procedure that was stratified by socioeconomic and educational level. The sample was made up of 394 children; 33.25% (n = 131) were females and the remaining 66.75% (n = 263) males. The mean age of the sample was 7.64 years old (SD: 2.33). The assessment battery included the Conners Rating Scales adapted for parents and teachers, the abbreviated version of the Wechsler Intelligence Scale for Children (WISC III) and for Preschool children Revised (WPPSI R), several academic achievement scales, development history and DISC IV. RESULTS: The estimated prevalence of ADHD was 10.15%, and a figure of 2.03% was obtained for the hyperactive type, 0.51% for the inattentive subtype, and 7.61% for the combined subtype. Prevalence was higher for males, the ratio being 3:1. Subjects performance in the cognitive and academic measures was within the average interval. CONCLUSIONS: The prevalence of ADHD in our population oscillates around the average figures reported in other countries. This study confirms the prevalence of ADHD in the population of Venezuela, with a distribution of subtypes and in terms of gender similar to those reported in the literature.
