Most autistic people are likely undiagnosed, unidentified adults. Lack of awareness about

autism has led to a “lost generation” of autistics: autistic people who have not been identified by

clinicians. Even today, many autistic children go undiagnosed because of the poor

understanding of autism and its many presentations.

Due to increased awareness and the amplified voices of autistic people, many adults who went

undiagnosed as a child are now discovering that they might be autistic. For many, this

realization is the first step on a journey toward self-discovery and clarity. We created this book to

guide you through your self-assessment and/or the clinical assessment process and to help you

advocate for yourself. We hope that this guide will help you through this process and after it.

This guide is mainly directed at adults who think they might be autistic. This guide may also

serve as a source of information for anyone seeking to learn about autism and better

understand autistic people.
