Autism spectrum disorder (controversial link)

Autism spectrum disorder (ASD) is a neurological condition that affects how a person perceives and interacts with the world. It involves differences in communication, social interactions, and behaviors, with symptoms varying widely among individuals. While genetics play a significant role, some studies have explored possible environmental factors, but there is no conclusive evidence linking vaccines or specific exposures to ASD. The term "controversial link" refers to debates and ongoing research about what causes autism, emphasizing that current scientific understanding recognizes it as a complex interplay of genetic and environmental factors without definitive links to any single cause.
