Autism, also known as autism spectrum condition (ASC) or autism spectrum disorder (ASD), is a neurodevelopmental condition that affects how people perceive, experience and interact with the world. It is not an illness or something to be fixed. It is a different way of thinking, processing and being.
Autism is a spectrum, which means it presents very differently from person to person. Some autistic people are highly independent and may not have received a diagnosis until adulthood. Others may need more significant support in daily life. Autism is also significantly underdiagnosed, particularly in women, girls and people from minoritised communities and many autistic people reach adulthood without ever receiving a diagnosis.
