Many of us are both Autistic and ADHD. The word we use is AuDHD. The overlap is large enough that clinicians once argued about whether the conditions could co-occur. The answer, established now, is yes, often, and the experience of AuDHD is not the simple sum of the two.
Autism pulls toward routine, structure, and depth. ADHD pulls toward novelty, change, and breadth. The AuDHD person is often both at once. Desperate for routine and unable to maintain it. Hyperfocused on a SPIN and also unable to start the thing on the list. Sensory-sensitive and sensory-seeking, sometimes within the same hour.
Two patterns running together
The traits do not cancel. They collide. The executive function difficulties are often more severe than in either condition alone. The time blindness is real. The starting problem is real. The stopping problem is real. The capacity to do twelve hours of inspired work on the thing you love, followed by three weeks of inability to open your email, is real.
The internal experience is often contradictory. The same person who needs the exact same breakfast every day also needs to take a different route to work every morning. The same person who cannot tolerate a change in plan also gets bored of the plan within the hour. None of this is a character flaw. It is two neurological patterns running in the same body.
Diagnosis is often sequential. Many of us were diagnosed ADHD first, and the Autism came later. For others, Autism came first, and the ADHD was hidden by the masking. The second diagnosis often explains what the first one did not, and vice versa.
Diagnosis is often sequential
Treatment and support have to hold both. ADHD medication sometimes helps Autistic sensory overload, sometimes worsens it. Autism-specific accommodations sometimes stabilise ADHD, sometimes produce an unbearable stillness. The two have to be considered together. Clinicians who treat them separately usually produce worse outcomes than clinicians who treat them together.
Treatment has to hold both
If you are AuDHD, you are not broken. You are not two conflicting people. You are one person, running on two overlapping neurologies, and the experience has a name because a lot of us share it.
The double rainbow is real. It is not a mistake. It is the weather.
