An online ADHD test can’t tell you whether you have ADHD, but it can help you pause and reflect on your own experiences. ADHD (attention deficit hyperactivity disorder) is a neurodevelopmental condition whose core symptoms are difficulty with attention, hyperactivity or inner restlessness, and impulsivity. Healthcare professionals often use questionnaires such as the ASRS to map adult symptoms. A diagnosis is always made in a professional assessment, which looks at whether the symptoms started in childhood and whether they cause difficulties in several areas of life. Below you’ll find a free adult self-check and an overview of how ADHD is assessed.
Key points
- An ADHD test is self-reflection, not a diagnosis. Only a healthcare professional can diagnose ADHD.
- In adults, ADHD often shows up as inner restlessness, trouble starting and finishing tasks, and hasty decisions.
- The ASRS is an adult ADHD symptom questionnaire that clinicians use as part of a wider assessment.
- The usual first step is your doctor, who can refer you to an ADHD specialist such as a psychiatrist.
- Support is available even without a diagnosis.
ADHD test: what it can and can’t tell you
There are many ADHD tests online, and many promise to tell you in a few minutes whether you have ADHD. No online test can do that. Recognizing ADHD takes the full picture: when the symptoms started, where they show up, what else could explain them and how much they affect daily life.
A test can still be useful. It can help you put words to experiences that have felt vague, and it gives you something concrete to bring to a conversation with a professional. Choose questionnaires carefully, though. Random quizzes can give a misleading picture in either direction. Among researched questionnaires, the ASRS (Adult ADHD Self-Report Scale, ASRS v1.1) is widely used with adults. It was developed with a World Health Organization workgroup, has 18 questions, and its first six questions are used as a short initial screener. Clinicians often use it as one part of an assessment.
Adult ADHD self-check
The list below is not the ASRS or any official test. It is a tool for reflecting on your own situation, and it is free. Read the statements calmly and think about how well they describe your everyday life over the past six months.
Attention and focus
- Your thoughts drift easily even when you try to focus, for example in meetings or while reading.
- Starting tasks is hard, even when you know they matter.
- You leave things unfinished once the first burst of interest fades.
- You often forget belongings, arrangements and deadlines.
- Your sense of time lets you down: you run late or keep misjudging how long things take.
Restlessness and hyperactivity
- You feel restless inside, even when you are sitting still on the outside.
- Staying put for a long time, for example in a queue or a lecture, feels uncomfortable.
- It is hard to wind down, and your mind always seems to be running at full speed.
Impulsivity and emotions
- You talk over others or answer before a question is finished.
- You make decisions or purchases on a whim and regret them later.
- Emotions flare up quickly, and frustration or irritation can come out strongly.
- Sometimes you get so absorbed in something interesting that everything else disappears (hyperfocus).
Finally, consider two questions:
- Were similar traits already there in childhood or adolescence?
- Do they cause difficulties in more than one area of life, such as work, study, relationships or home?
If you recognized yourself in many of the statements and answered yes to both final questions, it is worth talking to a professional. If you recognized only some, that is useful information too. Many of these traits can also be linked to stress, lack of sleep or exhaustion. If getting started is your biggest struggle, you may also find our article on ADHD paralysis helpful.
How does ADHD show up in adults?
Childhood hyperactivity often becomes less visible in adulthood. Many adults describe it as inner restlessness, a constant stream of thoughts or a need to always be doing something. Difficulty regulating attention can make it hard to start and finish tasks, and everyday life can take a lot of effort.
Impulsivity can show up as impatience, hasty words and decisions, or difficulty waiting your turn. ADHD also comes with strengths, such as energy, curiosity and the ability to get excited about things. Different presentations of ADHD emphasize different symptoms, so two people’s ADHD can look very different.
Long-term strain can also lead to exhaustion. We cover this in our article on ADHD burnout. You can find more on the different sides of ADHD on our adult ADHD page.
ADD or ADHD?
ADD is an older name for ADHD where hyperactivity is largely absent and inattention is the main feature. Current diagnostic classifications use the term ADHD and describe its presentations, one of which is the predominantly inattentive presentation. In everyday language, ADD is still a common term.
The inattentive presentation is easy to miss, because it doesn’t show up as disruptive behavior. A person may seem dreamy or absent-minded while working extremely hard to keep up. That is why this kind of ADHD is often recognized only in adulthood.
If you are looking for an ADD test for adults, you can use the self-check above. The attention and focus statements in particular describe the mainly inattentive presentation. The self-check can’t tell presentations apart, though: that is done by a professional during an assessment.
ADHD in women and girls
According to the NHS, ADHD is thought to be recognized less often in women than in men, and women with ADHD more commonly have inattentive symptoms, which can be harder to recognize. In girls and women, ADHD often shows up as inattention, inner restlessness and strong emotional ups and downs rather than visible hyperactivity.
If you are looking for an ADHD test for women, the self-check above works for you too. Pay particular attention to the statements about inner restlessness and emotions, as these are often where symptoms show.
Many women also learn to hide their difficulties: they put in extra effort, plan everything carefully and wear themselves out doing it. This is called masking, and you can read more in our article on ADHD masking. Often people first seek help for depression, anxiety or exhaustion, and ADHD is recognized only later.
ADHD assessment: how is ADHD diagnosed?
The usual first step is to talk to your doctor or another primary care professional. They can explore your situation and, if needed, refer you for an assessment with a mental health professional who specializes in ADHD. The assessment typically involves:
- A broad look at your wellbeing: first, your difficulties are looked at as a whole, including whether something else, such as sleep problems or another health condition, could explain them.
- A detailed ADHD assessment: if the picture points to ADHD, the assessment continues. It usually includes a clinical interview, questionnaires such as the ASRS, and information about childhood symptoms, for example from school reports or family members.
- Further testing if needed: sometimes a neuropsychological assessment is done to look at attention, memory and executive function.
For adults, the diagnosis is usually made by a psychiatrist, sometimes a neurologist. Assessments use international criteria such as the DSM-5, under which symptoms need to have been present before the age of 12 and cause difficulties in more than one area of life. Waiting times for specialist assessment vary a lot between countries and services.

Other things that can look like ADHD
Trouble concentrating, restlessness and irritability are not always caused by ADHD. Depression, anxiety, long-term stress, lack of sleep or exhaustion can all cause similar symptoms. That is why a professional assessment always looks at other possible causes too. If your mood has been low for a long time, you can also reflect on your situation with our depression test.
ADHD and other mental health challenges can also occur at the same time. Depression and anxiety are common alongside ADHD. Read more in our article on ADHD and depression.
What to do after the test
If the self-check brought up thoughts, the next step is to talk them through with a professional. It helps to prepare with a few notes:
- which things in daily life are hard, and in which situations
- how long they have gone on, and whether they were already there in childhood
- how they affect work, study, relationships or home
- what you have already tried and what has helped
Support is available even without a diagnosis, for example through your doctor, workplace health services or student health services. If ADHD is diagnosed, a professional plans treatment individually. It may include psychoeducation (learning about ADHD), practical everyday strategies, cognitive behavioral therapy and medication.
If the strain feels overwhelming or you have thoughts of harming yourself, you don’t have to face it alone. Call your local emergency number or your local crisis helpline.

Frequently asked questions
How can I find out if I have ADHD?
Online tests and self-checks help you reflect on your situation, but only a professional can diagnose ADHD. The process usually starts with your doctor, and the assessment includes an interview, questionnaires such as the ASRS, and a look at your childhood symptoms.
Which parent does ADHD come from?
ADHD can be passed down from either parent. It isn’t inherited only from the mother or the father; many genes play a part. According to the NHS, ADHD may be caused by genetic differences and often runs in families. The environment also affects how symptoms show up.
How much does an ADHD test cost?
Online ADHD tests are usually free, and the self-check on this page is free too. The cost of a professional assessment depends on your country, your health system and whether you go through public or private services, so it is worth checking in advance.
How does ADHD show up in girls and women?
In girls and women, ADHD often goes unnoticed because symptoms show more on the inside than on the outside, and recognition can be delayed into adulthood. Many hide their difficulties by overachieving, which can lead to exhaustion.
