When he was three years old, author Ayush Agrawal’s younger brother was diagnosed on the autism spectrum. Before Aryan’s diagnosis, their parents had never heard of autism. Why had this happened? What could be done to help him? Who could serve as a guide?

Autism is the fastest‐growing developmental disability in the world, with more than six million children in the United States alone affected by the disorder. An autism diagnosis holds different meanings for everyone. It is a diverse condition, a spectrum of challenges that no one has been able to fully understand yet.

Iterating Autism: Approaching the Autism Spectrum with a Design Thinking Mindset is a reflection of one young man’s unique way of looking at and experiencing the growth of a younger brother on the autism spectrum. Ideas of personalized, iterative approaches are what form the core of this book, supported by stories of the author's own family as well as valuable insights from experienced professionals, including Dr. Suzanne Goh, BCBA Karina Sizemore, and Professor Lawrence Fung.

Together, let’s try to find more meaning, happiness, and fulfillment for ourselves and our loved ones on the spectrum, whatever those words mean to you.
