Is this the ADHD or the autism talking?
With both, the two profiles tangle — novelty vs sameness, indifference vs distraction — and the same behaviour can come from either. Below: tests to tell which is which, so you pick the coping that fits.
When you have both, a single behaviour can spring from either side — and the right fix depends on which. Below: concrete tests (effort vs indifference, dopamine-hit vs grounding) for telling the ADHD trait from the autistic one, so you stop applying the wrong strategy.
This page isn't typically flagged for the selected profile — shown because you opened it directly.

Pace your days by neurotype
The AuDHD hyperactive side and the autistic side that needs calm and routine pull against each other. Rather than run both flat out, label an out-and-about day a 'hyperactive day' and deliberately book a quiet, low-demand 'autism-friendly' recovery day after it — routine days bank the energy that a spontaneous day spends.

The interest test: dopamine hit vs grounding
To tell an ADHD interest from an autistic special interest, ask why it's pursued and for how long. ADHD interest is a short-lived dopamine hit that fades once the novelty is gone; an autistic special interest is returned to over a long time for comfort, harmony and grounding — and it doubles as a self-regulation tool.

Check recovery speed, not just organization
Being organized isn't evidence against ADHD. Order can be effortful ADHD scaffolding built over years, or natural autistic order. Tell which by what happens when the system collapses: a fast rebuild points to natural autistic order; a very slow one (sometimes years) points to effortful ADHD scaffolding.

Is it distraction or sensory overload?
When someone repeatedly leaves a room or panics, don't assume defiance or pressure. ADHD distraction is curiosity-driven movement between things; autistic sensory overload is a physical assault — sound piercing the ears, a smell triggering a gag, closeness feeling scratchy. Ask why, look for sensory triggers, and accommodate the input.

Tell hyperfocus from sustained attention by interrupting it
ADHD hyperfocus and autistic sustained attention look identical from outside but behave oppositely when broken. Hyperfocus is a crisis-and-deadline-driven surge that shatters badly on interruption and provokes anger, and is very hard to re-enter. Autistic sustained attention comes from enjoyment, tolerates gaps, and resumes at will. Test which you're in by whether it survives a break.

The effort test: indifference vs distraction
When something looks like 'not paying attention', check whether effort was even attempted. Autistic indifference means no interest, so no effort goes in at all; ADHD inattention means effort starts but can't be sustained — the person engages and then gets pulled away. Same surface, different fix.
