Final answer:
The estimated prevalence of Asperger's syndrome, now part of the Autism Spectrum Disorder (ASD), is about 1 in 54 children. The prevalence of ASD has increased over the years, potentially due to increased awareness and improved diagnosis.
Step-by-step explanation:
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social interaction, communication, and engagement in repetitive behaviors or interests. The estimated prevalence of Asperger's syndrome, which is now considered part of the ASD spectrum, has changed over time. Current estimates suggest that about 1 in 54 children have ASD.
The prevalence of ASD has increased over the years, partly due to increased awareness and improved diagnosis. In 2005, the estimated prevalence was 1 in 166 children, and it increased to 1 in 88 children in 2012. The rate of ASD diagnosis varies among different studies and populations, but the overall trend indicates a higher prevalence than previously thought.
It's important to note that ASD is more prevalent in males than females, with a ratio of approximately 4:1. However, it's crucial to remember that each individual with ASD is unique, and the severity of the disorder can vary widely from person to person.
