Obsessions, repetitive behaviour and routines can be a source of enjoyment for people with autism and a way of coping with everyday life. But they may also limit people's involvement in other activities and cause distress or anxiety.
Repetitive behaviour in people with autism is not the same as OCD (Obsessive Compulsive Disorder), which is an anxiety disorder in which people experience repetitive thoughts and behaviours that are upsetting to them.
