Why support for one condition may leave another barrier
Overlapping traits do not mean identical needs
Autism and ADHD are neurodevelopmental conditions that can coexist. Attention regulation, sensory processing, communication and flexibility can interact in different ways. There is no single combined profile that explains everyone.
For you, the useful question is what a situation demands. A long group discussion might require tolerating noise, interpreting what others mean and holding your own point in mind. Removing one demand may help without resolving the others.

External structure can reduce the work of following a plan
A routine can provide predictability while still depending on working memory, task initiation and switching. Those executive demands can make a suitable routine hard to carry out with ADHD.
Keeping a short sequence visible and placing items where the action happens are ways to reduce those demands. If a support plan only says ‘keep a routine’, ask to work through the exact point where your routine breaks down.
Processing and retaining therapy content
NICE's adult autism guidance supports concrete, structured psychological work with communication and environmental adjustments. ADHD can add difficulty sustaining attention and remembering the action later.
You might therefore need both a clearer explanation and a reminder to use it. These serve different purposes. Tell your therapist whether you did not understand the exercise, understood but forgot it, or remembered but could not begin.
Treatment aims need to stay specific
ADHD medicines target ADHD symptoms; they are not treatments for autism itself. NICE permits the usual ADHD medication choices with autism, with slower titration and closer monitoring.
Ask for progress to be judged against your own goals, such as following a meeting or leaving home with less difficulty. The combined-condition guidance is largely expert consensus; it does not establish a single best adaptation for every autistic adult with ADHD.
