Welcome to my Autism Guide for the Newly Diagnosed Adult.
Autism, or Autism Spectrum Disorder (ASD), is a lifelong neurological difference that affects how a person communicates, processes sensory information, and interacts socially. It presents differently in everyone, with strengths and challenges unique to each individual.
Receiving an autism diagnosis in adulthood often comes with feelings of alienation, regret, anger, and grief. Many adults who receive a late diagnosis have spent years misunderstanding themselves and being misunderstood. Emphasis has been given to autistic voices whenever possible, centering the perspectives of those with lived experience throughout this guide.
The goal of this guide is to ease the journey of self-discovery such a diagnosis inevitably leads to, while providing the validation and community connection late diagnosed autistic adults have often lacked throughout their lives.
Emphasis has been given to autistic voices whenever possible. You’ll find medical reference books and databases meant to provide a variety of primary source research materials on autism as a medical diagnosis. You’ll also find support networks, community hubs, and books about the autistic experience written by autistic people.
The resources included here focus on up-to-date research, personal experiences, advocacy, and practical support. Whether you are just starting to learn about autism or are seeking deeper understanding and community connection, this guide aims to provide reliable, accessible, and inclusive materials.
Throughout this guide, I’ll use identity first language. This is my personal preference as an Autistic Woman, and is in no way intended to make a statement or invalidate the preferences of others.

Rediscovered: A Compassionate and Courageous Guide for Late Discovered Autistic Women
Asta, C. (2025). Rediscovered: A compassionate and courageous guide for late discovered autistic women (and their allies). Jessica Kingsley Publishers.
Catherine Asta is a late diagnosed autistic woman, psychotherapist, and the host of the hit podcast The Late Discovered Club dedicated to sharing the stories of late diagnosed autistic women, building community, and networking worldwide.
Asta combines her own experiences with the experiences of 100 other autistic women to create a guide to autistic womanhood from relationships to menopause.
Autistic women are more likely to be misdiagnosed than their male autistic peers. Some research indicates that up to 80% of autistic women are still undiagnosed by age 18 (UCLA Health, 2024).
This book may be of interest to late-diagnosed Autistic Women, their friends and family seeking to gain a better understanding of the autistic experience through the lens of womanhood. Late-diagnosed Autistic Women may find this book helpful while exploring autism as a new facet of their identity.
This resource’s front matter includes a table of contents, acknowledgments, and an introduction. It is organized into standard chapters with descriptive headings.

Peña, E. V. (Ed.). (2019). Communication alternatives in autism: Perspectives on typing and spelling approaches for the nonspeaking. Toplight Books.
Communication Alternatives in Autism: Perspectives on Typing and Spelling Approaches for the Nonspeaking, published in 2019, is an edited anthology of firsthand accounts written by nonverbal autistic individuals on their experiences with various communication methods, including controversial methods such as the rapid prompting method (RPM) and facilitated communication (FC).
This book is a valuable firsthand collection on alternative communication and disability rights, with a conclusion that covers best practices for educators written by an expert in the field of education. It is an excellent guide for educators, especially considering the conclusion, as well as a window into the lived experiences of nonspeaking autistic individuals. It can be used to increase understanding and empathy, and to advance disability rights.
Contributors to this collection include Tracy Thresher, Larry Bissonnette, Amy Sequenzia, Ido Kedar, Samuel Capozzi, Dillan Barmache, Henry Frost, Emma Zurcher Long, Philip Reyes, and Rhema Russell. It was edited by Edlyn Vallejo Peña, an associate professor of higher education leadership and the director of the Autism and Communication Center at California Lutheran University in Thousand Oaks, California, with an extensive history of writing and editing books in this field. It is organized into sections and individual chapters with an introduction and conclusion, both written by the editor. It is easily navigable via a table of contents, section headings, and chapter headings. The presence of a back-of-book index is unknown, but front matter includes a table of contents, preface, and introduction by the editor. The intended audience includes educators specializing in autism, parents and families of nonverbal autistic individuals, anyone seeking to gain a greater understanding of communication alternatives, and nonspeaking autistic individuals, and the autistic community itself.

Black Autistic individuals are more likely to be misdiagnosed and subject to violence and brutality due to their autistic traits than their non-Black Autistic peers.
This book may be of interest to recently diagnosed Black autistic adults seeking community, shared experiences, connection, and validation within the unique context of being Black and Autistic. It may also be of interest to recently diagnosed autistic adults who are not Black, but wish to gain a better understanding of the unique struggles and experiences of Black individuals in the autistic community.
Organized into three parts with chapters. There is a table of contents and an introduction.

The Autism Society presents themselves as centered on the lived experiences of autistic individuals and has an extensive set of oversite committees that seems to support this. They primarily use person first language and stress the importance of the autistic persons right to autonomy. While they do provide some paid services, including corporate training, their focus remains strongly on its free resources, outreach, and advocacy.

The Autism Books by Autistic Authors Project is a collection of books of all genres and types written by or contributed to by autistic individuals. This website is a grassroots project run by a single anonymous autistic individual intending to add value to autistic spaces. It began as a personal collection by the creator as they began looking for resources authored by the “Actually Autistic.” As the creator is anonymous, this resource lacks complete credibility; however, the materials presented on the site are verifiable, and the list is more comprehensive than many others. It also adds credibility within the autistic community that the creator is self-disclosed as autistic. These books are written by autistic individuals, and many of them are about autism and the autistic experience. It includes books on autism, fiction, non-fiction of other subjects, poetry, short stories, and academic books. This source is intended to be used to find books, both on autism and recreational, written by autistic authors, so that firsthand voices have a chance to speak out on their lived experiences and autistic voices can be celebrated. The landing page includes three featured pages: 2025 Book Releases, Nonspeaking Authors, and BIPOC Authors, as well as a list of topics to choose from or a list of publication years to choose from. It is very simple and easy to navigate. Each topic page is organized as a gallery of cover images that link to an outside, unaffiliated source where the book can be purchased. Content is up to date and includes pending 2026 releases. The site was last updated on August 3rd, 2025. The creator transparently discloses that they include authors who are both formally diagnosed and self-diagnosed and that they consider self-diagnoses valid. Books contained in the collection must mention in the description or summary information that the author is autistic to be included, but claims of autism are not vetted. The creator discloses that they attempt to weed out AI-generated work but acknowledges that that’s a difficult, if not impossible, process. There may be some AI-generated work included in this collection as a result. The site is not intended to sell anything. The books contained within this collection are linked to valid, unaffiliated sources that confirm the works are truly published and that the authors are self-identified as autistic. This is a collection intended for informational and ready reference purposes only and as such does not include citations or references. This resource is primarily intended for anyone in the autistic community looking for written work created by other autistics, but also for a wider audience to combat the notion that autistic individuals can’t write publishable works. I conducted a Google search for “autistic authors.”
Autistic Women & Nonbinary Network. (n.d.). Resource library.
The Autistic Women & Nonbinary Network (AWN) is a nonprofit founded in 2010 that advocates for and supports autistic women, marginalized genders, and nonbinary individuals. Their resource library offers a variety of free materials and webinars focusing on autism and social justice.

National Institute of Mental Health. (n.d.). NIMH data archive (NDA). National Institutes of Health. https://nda.nih.gov/
The National Institute of Mental Health Data Archive (NDA) is a comprehensive collection of mental health research data collected by the U.S. government, primarily meant to enhance ongoing research and provide summary data to the public. The NDA primarily contains anonymous human data from mental health research that has been normalized to a set standard. As a facet of mental health research, this resource houses government-collected data on autism and initially began as a database exclusively dedicated to autism research. This source may be used to find the most up-to-date government-sponsored research on autism and as a convenient source for a large archive of past research studies.
The database has both basic and advanced search options on its landing page, though the advanced search consists of filtering options only. Searches can be filtered by type, including NDA studies, publications, collections, data structures, data elements, and experiments, as well as by site, such as the NIMH Data Archive and the Adolescent Brain Cognitive Development Study. Users cannot set additional limits beyond these. Faceted searching is available; however, the facets are identical to the filter-by-type options. The content is updated biannually, though its coverage range is not entirely transparent, it is presumably up to the last submission deadline of July 15th, 2025.
Content available to the public is abstracted and indexed only with links to any associated peer-reviewed research papers published in scientific journals such as Nature, Molecular Autism, Biological Psychiatry, and the Journal of Autism and Developmental Disorders. Content available to qualified government-sponsored researchers consists of anonymous, harmonized human subject datasets. There is no mechanism to sort material according to format, relevance, or date, making it somewhat difficult to use. Users cannot save to a temporary folder for printing or emailing. Account creation is restricted to verified research scientists and institutions.
The intended audience for this resource is research scientists in the mental health field; the data is restricted to verified researchers, with some limited access consideration given to the public. I conducted a preliminary Google search for “autism databases” and came across this database.
