To be diagnosed with autism spectrum disorder (ASD), a person needs to have “persistent deficits” in three domains; social interaction, communication, and restricted/repetitive behaviour. “Restricted/repetitive” behaviour includes rituals, stereotypy (repeated movements), and restricted interests in specific topics, or “special interests”.
I feel it doesn’t get as much attention, and as someone diagnosed with autism at the age of 10, I’d like to share a bit about how some of my restricted/repetitive behaviour evolved over time – using an analogy to illustrate why some things just “stick” and “become a thing”; how they become absorbed into my daily routines.
