The aim of this study was to report the prevalence and characteristics of
children with cerebral palsy (CP). METHOD: Children with CP (n=451) were
ascertained by the Autism and Developmental Disabilities Monitoring (ADDM)
Network, a population-based, record-review surveillance system monitoring CP in
four areas of the USA. Prevalence was calculated as the number of children with
CP among all 8-year-old children residing in these areas in 2008. Motor function
was categorized by Gross Motor Function Classification System level and walking
ability. Co-occurring autism spectrum disorders (ASD) and epilepsy were
ascertained using ADDM Network surveillance methodology. RESULTS: The period
prevalence of CP for 2008 was 3.1 per 1000 8-year-old children (95% confidence
interval 2.8-3.4). Approximately 58% of children walked independently.
Co-occurring ASD frequency was 6.9% and was higher (18.4%) among children with
non-spastic CP, particularly hypotonic CP. Co-occurring epilepsy frequency was
41% overall, did not differ by ASD status or CP subtype, and was highest (67%)
among children with limited or no walking ability. INTERPRETATION: The prevalence
of CP in childhood from US surveillance data has remained relatively constant, in
the range of 3.1 to 3.6 per 1000, since 1996. The higher frequency of ASD in
non-spastic than in spastic subtypes of CP calls for closer examination.
