Adult ADHD, or Something That Looks Like It?
Adult ADHD is genuinely under-diagnosed. It is also genuinely over-assumed. Both of those are true at once, and the difference matters.
Two things are true at the same time. Adult ADHD is real, common and frequently missed, particularly in women and in anyone who did well enough at school to stay under the radar. And several other conditions produce a nearly identical picture, so starting from the answer is a poor way to reach it.
What adult ADHD tends to look like
- Starting things easily and finishing them rarely.
- Time behaving strangely: either no time has passed or four hours have.
- Sustained underperformance relative to genuine effort and ability.
- Impulsive decisions, in spending, in speech, in leaving jobs.
- Mental restlessness that does not switch off, more than physical fidgeting.
The important detail is that it is long-standing. ADHD does not begin at 34. It may only become unmanageable at 34, when the external structure that was quietly compensating disappears.
What else produces the same picture
- Chronic poor sleep, which reliably wrecks concentration and working memory.
- Depression, which slows processing and destroys initiation.
- Anxiety, which consumes the attention capacity you were trying to use.
- Trauma, which fragments concentration and is often missed entirely.
- Alcohol and stimulant use, in both directions.
- Thyroid problems, anaemia and other physical causes worth excluding.
Why the distinction is worth the extra appointment
Treating ADHD that is actually untreated depression will not work. Treating depression that is actually untreated ADHD will not work either. And stimulant medication given to someone with a significant untreated anxiety disorder can make things considerably worse. A structured assessment is not gatekeeping. It is what makes the treatment work.
What a proper assessment covers
Childhood history, because the criteria require it. Current functioning across more than one setting. A deliberate look at the alternatives above. Where possible, some account from someone who knew you as a child or knows you well now.
If you are already certain you have ADHD, bring that. Self-recognition is often accurate and is taken seriously. It is checked rather than dismissed.
