Autism Spectrum Disorder (ASD) is a developmental condition that affects how a person thinks, interacts, and experiences the world. It is called a "spectrum" because it includes a wide range of symptoms and abilities, which can vary significantly from one individual to another. People with ASD may have challenges with communication and social skills, and they may also engage in repetitive behaviors. The exact cause of ASD is not fully understood, but research suggests that both genetic and environmental factors may play a role. Early diagnosis and intervention can help improve outcomes for individuals with ASD, allowing them to develop essential skills and lead fulfilling lives.
