If you have ADHD, you probably know the experience well: something catches your attention, and then it's the only thing that exists. The hyperfixation doesn't ask permission. It doesn't check if you have other things to do. It just arrives, takes over, and makes everything else feel like background static.
The ADHD brain runs on dopamine. More specifically, it runs on dopamine availability — and for a lot of ADHD brains, dopamine is inconsistently distributed. Tasks that need to happen don't trigger the same reward response they do in neurotypical brains. But something that captures genuine interest? The dopamine shows up. Sometimes it shows up hard.
This is why hyperfixations in ADHD can be so all-consuming. The brain isn't malfunctioning — it's found something that works with it rather than against it. The focus that feels impossible when you're trying to do your taxes is suddenly effortless when you're researching the complete history of a niche video game franchise at 2am. Same brain. Completely different experience.
The problem isn't the fixation. It's the lack of record. When you've had dozens of these — and most ADHD adults have — they start to blur. You remember that you went through a phase, but you can't remember when. You can't see the pattern of how often they come, how long they last, what tends to trigger them. You lose the data on yourself.
That's where tracking comes in. Not to pathologise the experience, not to try to stop it happening — but just to have a record. To know: I was in this for 47 days. It peaked around day 30. It started right after that stressful work period ended. That information is actually useful.
Over time, a log of your fixations tells you something about how your brain moves through the world. It tells you what kinds of things tend to hold your attention longer. It shows you the gaps between fixations — the directionless stretches that often feel worse than they are, but that you can recognise now because you've seen them before.
There's also something less analytical about it. A record of your hyperfixations is a record of yourself — of what mattered to you, when, and with what intensity. That's worth having. Not just to understand your brain, but because those fixations shaped you in ways that are easy to forget once the dopamine has moved on.
Start simple. Log what you're fixated on, when it started, how intense it feels. You can add notes. You can track when it fades. The data will start to mean something. It always does.
