A number of the Autistic people I interviewed for this book are also ADHDers. So are many of the writers, mental health providers, and activists I quote. Within the Autistic self-advocacy community, people with ADHD are usually treated as honorary members by default. And the more we learn about the two neurotypes, the less they seem like distinct categories. They are, in every sense, sibling disabilities, two highly similar groups who belong in community with one another.
