Fact sheet

Autism

Autism is a lifelong difference in how people communicate, relate to others and experience the world. Autistic people may have focused interests, prefer routine, and find sounds, lights or textures much stronger or weaker than others do. Autism is not caused by parenting or vaccines. Many people, especially women and girls, are first diagnosed as adults. Autism isn’t something to cure: support aims at wellbeing, communication and taking part in life as the person chooses.
