# Hyperfocus: what it is, why it happens in ADHD and when it becomes a problem > You sit down for a moment with something that interests you and, when you look up, it is two in the morning and you have not eaten. What hyperfocus is, how it relates to ADHD and which test can guide you. *https://mypsicotest.com/en/blog/adhd-hyperfocus/ · Published: 2026-10-10 · 7 min read · MyPsicoTest team* You sit down at nine to check something quickly on the computer. When you look up it is two in the morning, dinner has gone cold next to the keyboard and you have three unanswered messages. The next day, on the other hand, you cannot read a work email without drifting off five times. That mix confuses a lot of people, and it has a name: **hyperfocus**. This guide explains what it is, what research says about its link with ADHD, how it differs from flow, when it helps and when it becomes a problem, and which test can help you see whether something else lies behind it. ## What is hyperfocus? Ashinoff and Abu-Akel define it in their [review of hyperfocus](https://pmc.ncbi.nlm.nih.gov/articles/PMC7851038/) as complete absorption in a task, to the point where a person appears to tune out everything else. Their example is a child so engrossed in a video game that they do not hear a parent calling their name. Other authors describe it as a passing experience of intensely focused attention in which you lose track of time and of what is happening around you. It tends to appear with activities that are particularly fun or interesting. And although almost everyone has experienced something similar at some point, it is mentioned above all in **ADHD**, autism and schizophrenia. The review also warns that the term is poorly defined: many studies use it without explaining what they mean by it, and there is no consensus definition. ## Why hyperfocus happens in ADHD At first sight it looks like a contradiction. Hupfeld and colleagues put it this way: adults with ADHD often report long episodes of highly focused attention, which is surprising given how easily they tend to be distracted. One way to understand it is that in **ADHD hyperfocus** attention is not missing but hard to regulate: steering it towards what needs doing and pulling it away when necessary. ### What the studies say - **More symptoms, more hyperfocus.** In the [study by Hupfeld, Abagis and Shah](https://pubmed.ncbi.nlm.nih.gov/30267329/), with two samples totalling 623 adults, those with more ADHD symptoms reported more hyperfocus at school or work, in hobbies and in front of screens. - **Executive function explains part of it.** In 380 university students, García Pimenta and colleagues found that difficulties with executive functions, the ones that help us plan, organise ourselves and switch tasks, partly explained the link between ADHD symptoms and hyperfocus. They did not explain hyperfocus during rewarding activities, which also points to reward sensitivity. ### It is not exclusive to ADHD A [study by Groen and colleagues](https://pubmed.ncbi.nlm.nih.gov/33126147/) of 1,124 adults without a diagnosis found that hyperfocus was more frequent the more ADHD traits a person had, and less frequent with age and with more education. But when they compared 78 patients with ADHD with similar healthy people, they found no differences in how often or how long it occurred. The only difference was that in the patients hyperfocus was less likely to occur in educational and social situations. Their conclusion is clear: hyperfocus is not specific to ADHD. That is also why it is not part of the official criteria. Diagnostic manuals describe ADHD through two groups of symptoms, inattention and hyperactivity-impulsivity; hyperfocus is one of the features clinicians often recognise in adults, along with emotional dysregulation and low tolerance for boredom. ## Hyperfocus and flow: not the same thing They are easy to confuse. Flow, as described by Nakamura and Csikszentmihalyi, happens when a task offers a challenge that matches your skills, with clear goals and immediate feedback on how you are doing, and it is experienced as positive. The data suggest they are different experiences. When validating a 12-item hyperfocus questionnaire with 347 adults, Hupfeld's team found that hyperfocus was closely linked to ADHD traits, somewhat less to mind wandering, and barely related to flow at all. It also had a weak negative link with grit: getting hooked on something is not the same as perseverance. ## When hyperfocus helps and when it is a problem Hyperfocus is neither good nor bad in itself. It depends on where it shows up and what it crowds out. The three settings Hupfeld studied are a useful guide: | Setting | When it can help | When it becomes a problem | |---|---|---| | Work or studies | You get through a task that interests you in a few hours | You get stuck on one part and neglect the rest or your deadlines | | Hobbies | You enjoy yourself and learn a lot | You lose track of time and of what you were meant to be doing | | Screens | When it is a chosen break to switch off | Hours on your phone, series or video games without noticing | ![Woman lying on the floor drawing, absorbed in her work and surrounded by sheets of paper, an image of hyperfocus in a hobby](https://mypsicotest.com/assets/img/blog-hiperfoco-aficion-1200.webp) It is worth paying attention if: - You skip meals or go to bed very late because you cannot stop. - You are late for appointments or forget commitments while you are hooked on something. - Important but boring tasks pile up while you spend hours on what you enjoy. - Your partner, family or colleagues complain that you "disappear". - You find it extremely hard to switch tasks even when you know you should. ## Is there a hyperfocus test? Research has specific questionnaires, such as the one developed by Hupfeld and colleagues, but they are tools for studies. And because hyperfocus is not a diagnostic criterion, on its own it does not tell you whether you have ADHD. MyPsicoTest does not have a hyperfocus test. What we do have is the [ADHD Test](https://mypsicotest.com/en/adhd-test-adults/), which looks at the other side of the coin: what happens to your attention when a task does not grab you. One of its statements reads: "I have trouble keeping my attention on long or boring tasks, such as reading a report or following a meeting." Others ask whether you start projects enthusiastically but struggle to finish them, or put off tasks that require sustained mental effort. There are 18 statements about the last six months, answered in about five minutes according to how often each applies, grouped into two areas: - **Inattention:** careless mistakes, difficulty getting organised, forgetfulness, distraction. - **Hyperactivity and impulsivity:** restlessness, difficulty waiting or not interrupting, impulsive decisions. The score ranges from 0 to 72 and falls into four bands. You do not need to sign up, and your answers are not sent to any server. A high score is not a diagnosis, but it is a good reason to ask for an assessment. ### Other tests that can help Because hyperfocus is also described in autism, if you also have very intense interests and find relationships with others difficult, the [Autism (ASD) Test](https://mypsicotest.com/en/autism-test-adults/) can guide you. If what worries you most is not being able to concentrate on what you need to do, [Lack of concentration: why you can't focus and how to find the cause](https://mypsicotest.com/en/blog/lack-of-concentration/) may help. All the questionnaires, free and anonymous, are in the [psychological tests](https://mypsicotest.com/en/psychological-tests/) catalogue. ## How to make use of hyperfocus without it taking over The aim is not to get rid of it but to stop it deciding for you. Some ideas: - **Give it an external limit.** An alarm or timer brings you back when you cannot do it on your own. - **Choose where you let it in.** If you know a task will grab you, start it when you have time ahead of you, not just before an appointment. - **Protect the basics.** The NHS advises adults with ADHD to eat at regular times, get enough sleep with a regular bedtime and avoid screens close to bedtime, which is exactly what hyperfocus tends to crowd out. - **Ask for structure.** The NHS also mentions, as a workplace adjustment, help from another person to plan and structure your tasks. - **Agree a signal with the people you live with.** So that someone can let you know without it feeling like a hostile interruption. If hyperfocus and distractibility are costing you work, sleep or relationships, an assessment is worth considering. We explain what happens in therapy in [ADHD therapy for adults: what a psychologist works on and when it helps](https://mypsicotest.com/en/blog/adhd-therapy-for-adults/), and at the end of the test you will find our recommendation of a licensed psychologist who works with ADHD in adults, online too. ## Frequently asked questions ### What is hyperfocus? It is a state of complete absorption in a task, to the point of ignoring everything else and losing track of time. It tends to appear with activities that are particularly interesting or rewarding. ### Is hyperfocus a symptom of ADHD? It is not part of the official criteria, but it is very common in adults with ADHD. Studies find more hyperfocus the more ADHD symptoms a person has. ### Do only people with ADHD experience hyperfocus? No. Almost everyone experiences it at some point, and it is also described in autism. One study found no difference in how often it occurred between patients with ADHD and people without the diagnosis. ### What is the difference between hyperfocus and flow? Flow is an enjoyable concentration on a task that offers a challenge matched to your skills, with clear goals. Hyperfocus is linked more to ADHD traits and to difficulty letting go of an activity, and in one study it was barely related to flow. ### Is hyperfocus good or bad? It depends. It can help you get through something that interests you, but it becomes a problem when it makes you skip meals or sleep, forget commitments or neglect important tasks. ### How do you get out of hyperfocus? With external help: alarms, timers, a signal agreed with someone you trust and starting the tasks that grab you when you have no commitments straight afterwards. ### Is there a hyperfocus test? Research uses specific questionnaires. At MyPsicoTest, the ADHD test does not measure hyperfocus, but it does measure the inattention and impulsivity that often come with it, and it helps you see whether an assessment is worth it.
