Everything is Connected to Everything: Improving the Healthcare of Autistic & ADHD Adults


ATT String Graphic

Autistic & ADHD adults often have multiple intertwined health conditions.

Barriers within the healthcare system may interfere with clinicians having access to address all of someone’s medical problems all at once. Yet by treating these medical conditions as separate, this may result in a person not getting better.

Thinking of these medical conditions as a group (or cluster / constellation) may result in more improvements.

We hope that the resources on this website can make things easier for patients and clinicians to communicate and work through these patterns together.

About the project

Founded by an autistic doctor, All Brains Belong VT is a nonprofit healthcare and community organization in Montpelier VT. All Brains Belong provides neuroinclusive medical care in addition to social connection and educational programs. The majority of our adult patients are autistic and/or ADHD. This project was inspired by the patterns we see in our patients. The majority of our autistic and ADHD adult patients suffer from a constellation (grouping) of related medical conditions. We found that many of the common medical treatments for some parts of this grouping made others worse.

In May 2022, we formed a Task Force of clinicians, patients, and community members to discuss what works (and does not work) to manage these medical conditions or symptoms. We also gathered information from more than 100 autistic adults. These individuals gave feedback based on their personal experiences. The content we share on this website combines evidence-based medicine, lived experience, and our clinical experiences treating patients with these conditions.

Why is this important?

The average life expectancy for an autistic adult is 36-54 years.1,2 The main reasons for this are early heart disease and suicide.3 ADHD adults also have more medical problems and a shorter life expectancy.4 69% of autistic adults have untreated health problems.5

‘We believe that the results shared in this project will help autistic and ADHD adults to live longer, happier lives.
