How to Prepare for Your ADHD Assessment

An ADHD assessment is a conversation, not a test you can pass or fail. There's no trick question and no score to chase. Knowing roughly what the appointment covers, and what to bring with you, mostly just removes the anxiety of walking in blind.

What the appointment usually covers

Most clinicians work through a structured interview that asks about the same set of attention and hyperactivity/impulsivity traits twice: once for how they show up for you now, and once for how they showed up in childhood, roughly ages five to twelve. For each one, they're not just checking whether it applies, they're asking how it's actually affected you, at work or in education, in relationships, in your social life, in how you see yourself. The interview is built around real-life impact, not a checklist you either tick or don't.

Why they keep asking about childhood

This surprises a lot of adults going in. ADHD criteria require symptoms to have been present before adulthood, so the clinician needs some picture of what you were like as a child, even if that's decades ago and your memory of it is patchy. If a parent, older sibling, or partner who's known you a long time is willing to sit in on part of the appointment, or write a short note beforehand, that collateral perspective can fill in gaps your own memory can't reach. It's helpful, not required.

What to bring

• Specific, dated examples, not summaries. "Missed a work deadline on March 3rd because I opened the document four times and closed it again" is more useful than "I struggle with deadlines."
• Examples across more than one setting. Work, home, relationships, and free time all count. A pattern that shows up everywhere is more informative than one confined to a single stressful period.
• Anything you already have on childhood: old school reports, a parent's recollection, anything that speaks to what you were like before adulthood gave you more ways to compensate.
• A written list, if talking under pressure is hard for you. Handing over notes is completely normal and clinicians expect it.

What it isn't

There's no answer that disqualifies you, and there's no way to "fail" by admitting a symptom doesn't apply. Don't try to match your experience to a list you found online, and don't exaggerate to make sure it "counts." Assessors are trained to weigh a genuine, specific account differently from one written toward an expected outcome. Bring your actual experience. That's the whole job.

Where Witnes fits

The dated, specific examples above are exactly what a running log builds over time. Witnes is a private daily record, a few minutes a day, that captures situations while they're fresh so you're not reconstructing months of your life from memory the night before your appointment. It doesn't diagnose or interpret anything, it just keeps the record you'd otherwise lose.
