Autism Spectrum Disorder (ASD) is a developmental condition that affects how a person thinks, interacts, and experiences the world. People with ASD may have challenges with communication and social skills, and they often display repetitive behaviors or intense interests in specific topics. The term "spectrum" reflects the wide range of symptoms and abilities that individuals with autism can have. While the exact cause of ASD is not fully understood, it is believed to involve a combination of genetic and environmental factors. Early diagnosis and intervention can significantly improve outcomes, helping individuals with autism lead fulfilling lives and develop meaningful relationships with others.
