Do I Have ADHD? Signs in Adults and What to Do Before Your Appointment

You can't know on your own, and an online quiz can't tell you. Confirming or ruling out ADHD is the job of a qualified health professional, such as a psychiatrist, psychologist, or physician trained in adult ADHD, after a detailed conversation about your history, ideally with input from people who knew you as a child. What you can do yourself is get ready for that appointment: learn the most common signs in adults, fill out the ASRS v1.1 self-report screener, which was developed with the World Health Organization and is published by Harvard, and jot down concrete examples from your daily life. This page walks you through that path, with no score and no result: nobody here will tell you whether you have it or not.

If you suspect you have ADHD or take medication, talk to a health professional.

What are the signs of ADHD in adults?

ADHD (attention-deficit/hyperactivity disorder) is usually described through two broad groups of signs. In adults they show up differently than in children: hyperactivity, for example, may turn into restlessness on the inside.

Signs linked to attention and organization:

• Often losing or forgetting things (keys, phone, documents).
• Forgetting appointments and deadlines, even important ones.
• Trouble holding attention on long, repetitive, or boring tasks.
• Starting many things and finishing few.
• Putting off tasks that take a lot of mental effort.
• Getting pulled away by noises, thoughts, or anything around you.

Signs linked to restlessness and impulsivity:

• A feeling of a "motor running," trouble relaxing in free time.
• Fidgeting with hands and feet, getting up a lot in meetings or classes.
• Talking a lot, interrupting, finishing other people's sentences.
• Impulsive decisions or purchases.

Everyone has some of these now and then. What professionals evaluate goes well beyond a list.

What do professionals look at besides the signs?

In general, an evaluation considers whether the signs:

• have been there since childhood (not just for the last few months);
• show up in more than one area of life (work, school, home, relationships);
• cause real impairment in daily life;
• are not better explained by another condition, such as anxiety, depression, sleep deprivation, intense stress, or other health problems.

That last point matters: many situations can mimic signs of ADHD. That's why a professional evaluation is essential, and why internet quizzes aren't good for drawing conclusions.

What is the ASRS v1.1 questionnaire?

The ASRS v1.1 (short for Adult ADHD Self-Report Scale, version 1.1) is a self-rating scale for adults. It was developed in conjunction with the World Health Organization by a workgroup of psychiatrists and researchers tied to Harvard Medical School and New York University. The full checklist has 18 questions about how often everyday situations happen, split into Part A (6 questions) and Part B (12 questions). The six Part A questions make up the 6-question screener, which takes only a couple of minutes.

Where to find it:

• Harvard's National Comorbidity Survey page, which publishes the official ASRS v1.1 6-question screener as a PDF. Harvard states that using the screener is free and doesn't require formal permission, as long as it isn't altered and the copyright notice is kept. https://www.hcp.med.harvard.edu/ncs/asrs.php
• NYU's licensing page for the full 18-question checklist (checked 10/15/2026). It is distributed under a license, so we don't copy it here. https://license.tov.med.nyu.edu/product/asrs-v11-18-question-symptom-checklist

The screener itself says it can be used as a starting point to recognize signs and that it is not meant to replace a consultation with a trained health professional: it confirms nothing on its own. The right way to use it is to fill it out calmly and bring it to your appointment, so the professional can interpret it alongside your history. We don't score it for you, and you shouldn't treat any score as an answer.

What should you bring to the appointment?

Arriving prepared helps a lot, especially because it's common to forget in the moment what you meant to say. A practical list:

1. The completed ASRS screener, printed or on your phone.
2. Concrete, recent examples. "Last week I forgot two meetings," "I missed paying a bill three months in a row." Examples beat "I'm really distractible."
3. Since when. Memories from school: teacher notes, old report cards with comments, nicknames you heard.
4. A report from someone else. A parent, sibling, or anyone who knew you as a child can say what they saw. If they can't come, ask them to write it down.
5. Where it gets in the way. Work, school, money, relationships, driving, sleep.
6. Other health issues and everything you take (medicines, supplements, other substances), so the professional has the full picture.
7. Your questions. Write them ahead: what you want to understand, what worries you.

Where can you get evaluated?

• Through your primary care doctor: a good first stop. They can talk through your history and refer you to a specialist if needed.
• Through your insurance or privately: a psychiatrist or psychologist who works with adults. Neuropsychologists can also take part in the evaluation, with interviews and testing.
• University training clinics: many psychology and psychiatry programs offer lower-cost care supervised by faculty.
• Telehealth: an option in many areas, but check that the clinician is licensed in your state and uses a full evaluation, not just a quick quiz.

Be careful with online tests and videos

Scored tests on websites and "10 signs you have ADHD" lists on social media can be confusing. A 2022 study that analyzed the 100 most-viewed ADHD videos on TikTok classified about half of them as misleading. Use the internet to learn and prepare, not to conclude.

What about while you wait for the appointment?

The wait can be long. In the meantime, practical strategies help anyone who struggles to start, remember, and keep going, with or without ADHD:

• Reminders at the right time, instead of trusting your memory.
• Tasks broken into very small steps.
• A short timer to get started on what you're stuck on.
• A routine with a few fixed times (see ADHD Routine for Adults: Build One You Can Follow).
• Less guilt, more celebrating what you did get done.

Frequently asked questions

Is there an online test that tells me if I have ADHD?

No. No online test confirms ADHD. Questionnaires like the ASRS help you organize what you feel and talk with a professional, but a health professional is the one who evaluates.

Who can evaluate ADHD in adults?

Qualified health professionals, such as psychiatrists and psychologists, who often work together with neuropsychologists or your primary care doctor during the evaluation.

Can ADHD show up only in adulthood?

According to the criteria used today, the signs begin in childhood, even if they're only noticed or cause problems later, when responsibilities increase.

Where do I find the official ASRS questionnaire?

On Harvard's National Comorbidity Survey page (www.hcp.med.harvard.edu/ncs/asrs.php), which publishes the ASRS v1.1 6-question screener. Fill it out and bring it to your appointment.
