Abstract

INTRODUCTION: The prevalence of cerebral palsy in Western countries is estimated to be around 2 cases/1,000 inhabitants. The objective of this study was to estimate the prevalence of cerebral palsy in the Autonomous Community of Castilla y Le?n and to assess potential differences among the nine provinces of this region. PATIENTS AND METHODS: The number of patients with CP in 1999, separated by provinces and by age groups, was obtained from the Community Sectorial Program for Persons with Disabilities. These data originally came from handicap evaluations carried out in each base center. Prevalences were calculated using population data from the National Institute of Statistics. RESULTS: A total of 335 patients aged 0-13 years were registered as having a diagnosis of cerebral palsy in 1999. The prevalence of cerebral palsy was 1.05 cases/1,000 inhabitants aged 0-13 years. Statistically significant differences were found in the prevalence of cerebral palsy among provinces (p < 0.0001). The highest prevalence was found in Salamanca, with 1.87 cases/1,000 inhabitants, while the lowest prevalence was found in Segovia, with 0.33 cases/ 1,000 inhabitants. CONCLUSIONS: The prevalence of cerebral palsy in childhood in Castilla y Le?n was lower than that reported in western countries. Substantial differences were found among provinces. The prevalence of cerebral palsy is probably underreported in some provinces. These differences could be due to a disparity in diagnostic criteria, especially in young children.
