What it is
ADHD paralysis is the name people give to being stuck. You know what you need to do. You might even want to do it. And you still can’t start.
Sometimes it’s one big thing, like a tax return or a work report. Sometimes it’s twenty small things and you can’t pick one, so you do none of them. Either way you lose hours, and often you feel terrible about it afterwards.
It isn’t a medical term. Researchers tend to talk about task initiation or procrastination instead. Procrastination isn’t officially counted as an ADHD symptom, but it comes up so often that it’s a regular part of therapy for adults with ADHD.1 The diagnostic criteria do include often avoiding or being reluctant to do tasks that need mental effort over a long time, and often having trouble organising tasks and activities.2
What it feels like
You sit down to start. You open the document, read the first line, and close it again. You make a coffee. You tidy something that didn’t need tidying. You pick up your phone “for a second”.
Your head is busy the whole time. You’re thinking about the task, worrying about the task, telling yourself off about the task. You’re tired by the end of the day, but you haven’t done the thing.
From the outside it can look like you don’t care. From the inside it feels like pushing against a wall.
Why it happens
There isn’t one cause, and the research is still catching up. But a few things seem to be involved.
Executive function. These are the mental skills that let you plan, hold things in mind and stop yourself acting on impulse. A large meta-analysis of 83 studies found that, on average, people with ADHD had weaker scores on executive function tasks, with the clearest differences in response inhibition, vigilance, working memory and planning. The same review found these weaknesses weren’t present in everyone with ADHD.3 Starting a task leans on all of these. You have to work out the steps, hold them in your head, and keep pushing other things away while you begin.
Motivation. In Russell Barkley’s influential model of ADHD, regulating your own motivation is one of the functions that’s affected. He found the evidence for it among the strongest in his review.4 When a task is boring, far away or unclear, your brain doesn’t make the push to start on its own.
Feelings. A 2020 meta-analysis of 13 studies found adults with ADHD had much more difficulty regulating emotions than adults without it.5 Another review describes emotional difficulties as common in ADHD across the lifespan and a major contributor to the problems it causes.6 So a hard or unclear task doesn’t just feel like work. It can bring up dread, shame or fear of getting it wrong, and avoiding the task is a quick way to avoid the feeling.
Put those together and you get a loop. The task is unclear, so it feels big. It feels big, so it feels bad. It feels bad, so you avoid it. You avoid it, so it gets more urgent and feels worse.
None of this is a moral failing. It’s what happens when the parts of your brain that help you start are working harder than other people’s.
What helps
The aim isn’t to force yourself through the wall. It’s to make the wall smaller.
- Make the first step tiny. One adult ADHD therapy programme teaches a simple rule: if you’re having trouble getting started, the first step is too big, so break it down.7 Not “write the report”. “Open the file and write the title.” If that still feels hard, go smaller.
- Get it out of your head. Write the task down, then write the steps. In a well-known therapy trial for adults with ADHD, the skills included using a calendar and task list and breaking overwhelming tasks into steps.8 A brain dump is a good place to start.
- Use a short timer. Agree to do ten minutes, then stop if you want. Starting is the hard bit, and a short timer makes it easier to start. The same trial taught people to time how long their attention lasts, and to write distractions down rather than act on them.8
- Pick one, not the best one. When everything is waiting, choosing feels impossible. Pick any one task. Doing a less important thing is better than doing nothing.
- Be kind to yourself afterwards. Telling yourself off adds more bad feeling to the loop. Notice what got you stuck, and make tomorrow’s first step smaller.
The guide to starting the thing you’ve been avoiding shows one way to do this step by step. If getting stuck is affecting your work, money or relationships, it’s worth talking to your GP. Therapy built for adult ADHD can help with exactly this.
