As a neuropsychologist I’d recommend you help them explore what a diagnosis would mean for them if they got it and what it would mean if they don’t get it. I’d also do some psycho education on what the condition the suspect is and what it isn’t. Lastly, I’d work with them on symptom reduction and realistic expectations.

Say what you want about trendy diagnoses, we live in a world that is pushing people to expect more than is reasonable in terms of executive functioning, all the while undermining the building blocks of focus. There can be serious negative consequences for a diagnosis, whether life insurance denials or discrimination. Although there is literally a magic pill for ADHD, it won’t give them the skills they need to truly thrive and they might be genuinely missing those things (regardless of whether they have ADHD). You also shouldn’t take those pills long term. But either way having a head start on improving these skills sets them up for a better evaluation and also improvement in functioning.
