Overview
Autism Spectrum Disorder (ASD) is a neurological condition that influences how a person perceives the world and interacts with others. It's considered a "spectrum" because it affects individuals differently, with varying levels of support needs and unique strengths. This difference is present from birth and is a core part of an individual's identity. The exact causes of autism are not fully understood, but research suggests a combination of genetic and environmental factors. It is not caused by parenting styles or vaccines. Early recognition and support can significantly improve outcomes and quality of life for autistic individuals.
