Getting an adult ADHD diagnosis

Many adults wonder if lifelong trouble with focus, lateness or lost keys could be ADHD (attention-deficit/hyperactivity disorder). You are not alone. About 15.5 million U.S. adults, roughly 1 in 16, had a current ADHD diagnosis in 2023. About half of them were first diagnosed at age 18 or older.¹

There is no blood test or brain scan for ADHD. A diagnosis comes from a careful talk with a trained clinician about your life now and your life as a child.^2,3 This page walks you through the steps, what to bring, and how to avoid a rushed or careless evaluation.

Step 1: A quick self-screen

A good first step is the Adult ADHD Self-Report Scale (ASRS). It was developed with the World Health Organization. The short version has 6 questions about how often you have certain problems, such as finishing details of a project or staying seated.^4,5 The 6-question screener is free to use and comes in about 20 languages. There is also a longer 18-question symptom list and a newer version matched to today's diagnostic manual, called the ASRS-5.⁵

Keep two things in mind:

• A high score is a signal, not a diagnosis. Rating scales help the clinician, but they do not decide the answer alone.³
• A low score does not rule ADHD out. In the original study, the 6-question screener missed about 3 in 10 adults that clinicians rated as having ADHD.⁴

Be careful with quizzes on social media or random websites. Most online self-tests have not been checked by research, and none should be used to diagnose yourself.³ You can also try our general mood and stress check-in if you are not sure what is going on.

Step 2: Find the right clinician

Many kinds of licensed professionals can diagnose adult ADHD. These include psychiatrists, psychologists, family doctors, nurse practitioners, neurologists and clinical social workers.^2,3 What matters most is real training and experience with adult ADHD, not the type of degree.³

Good places to start:

• Your primary care doctor. They know your health history and can do the medical part of the check. Some will diagnose ADHD; others will refer you.²
• A psychiatrist or psychologist who lists adult ADHD as a focus.
• A university clinic or hospital ADHD program, if one is near you.

When you call, ask: "Do you evaluate adults for ADHD? What does your evaluation include? How long does it take?"

Step 3: What a full evaluation looks like

There is no single test.⁷ A careful evaluation usually takes one or more long visits and has several parts.

1. A detailed interview. The clinician asks about your symptoms now and in childhood. They also ask about school, work, money, driving, relationships, alcohol and drug use, and your medical and mental health history.³ Experts call this interview the core of an adult ADHD diagnosis.⁶
2. Rating forms. You fill out standard checklists. A partner, parent or close friend may fill out one too.^2,3
3. Childhood history. You may be asked for old report cards, school records, or a parent's memories of what you were like as a child.^2,6
4. A medical check. If you have not had a physical in the last 6 to 12 months, your clinician may suggest one. This looks for health problems that can cause similar symptoms. It cannot prove ADHD.³
5. A look for other conditions. The clinician checks your mood, sleep, anxiety, and current and past health problems.²
6. Sometimes, extra testing. Tests of memory, planning and reasoning can show strengths and weak spots or a learning disability.² They are not required to diagnose ADHD.⁶

What the clinician is checking for

Clinicians use the standard criteria in the DSM-5, the main diagnostic manual in the U.S. For adults, they look for these things:^2,3

Everyone loses focus sometimes. ADHD means the problems are frequent, long-lasting and cause real trouble in more than one setting.¹¹ To learn what the symptoms look like day to day, see Signs of ADHD in adults.

Why your childhood matters so much

ADHD starts in childhood, even if no one noticed it then.² That is why the clinician will ask so many questions about your early years.

Many adults do not remember childhood well. This is common, and it is not a reason to give up.⁶ Other people can fill in the gaps:

• A parent, older brother or sister, or longtime friend can share what they remember.³
• A partner can describe how symptoms affect your life now.⁶
• Old report cards may have teacher comments about daydreaming, unfinished work or talking in class.
• If no family is available, school or other records can help.⁶

Girls and women are more likely to have been missed as children.² Quiet, daydreaming types of ADHD are easy to overlook. People who are very bright or who built strong coping habits may also have hidden their symptoms for years.⁶

Ruling out look-alikes

Many problems can make it hard to focus, remember or sit still. A good clinician checks for these before deciding on ADHD. Some people have ADHD and one of these at the same time.^3,7,11

Other things your clinician may look at:

• Thyroid problems and seizure disorders, which can mimic ADHD.³
• Alcohol, cannabis or other drug use. Some adults use these to calm their symptoms. Substance problems are usually steadied first, before ADHD treatment.⁶
• Learning disabilities, which may need their own testing.³
• Autism and tic disorders, which are common with ADHD and can change the treatment plan.⁶
• Your medicines. Bring a full list, including vitamins and over-the-counter products, and ask if any could affect focus or sleep.

To learn how these conditions overlap, see ADHD with anxiety, depression and substance use.

Telehealth: helpful, but be careful

Telehealth has made ADHD care easier to reach. About half of U.S. adults with ADHD have used it for ADHD services.¹ Many good clinicians offer careful evaluations by video.

Rules for prescribing some ADHD medicines by video are also changing. Stimulant ADHD medicines are controlled substances (drugs with extra legal limits because they can be misused). Under a federal rule, clinicians can prescribe them by telehealth without ever seeing you in person through December 31, 2026.⁹ After that, the rules may change. Ask your clinic how they will handle refills if that happens.

A rushed diagnosis can lead to the wrong treatment. It can also miss a real problem, like sleep apnea or depression, that needs its own care. Rating scales alone are not enough for a diagnosis.³ Some careful clinics also use special tests to check that symptoms are not being exaggerated. These matter because some people seek a diagnosis to get stimulants.⁶

Getting diagnosed later in life

ADHD does not go away at 60. Studies suggest about 3 to 4 in 100 older adults have ADHD symptoms.⁶ Some people are first diagnosed in their 60s or later.

But new focus or memory problems that start later in life are not ADHD. ADHD must have started in childhood.² Problems that are new or getting worse need a check for other causes. These include mild cognitive impairment, early dementia, depression, sleep problems, hearing loss and medicine side effects. See Getting a dementia diagnosis and ADHD in later life.

Cost with Medicare: Medicare Part B covers psychiatric evaluations and diagnostic tests by many types of providers. After the yearly deductible, you usually pay 20% of the approved amount.¹⁰ Ask the clinic ahead of time if they accept Medicare.

How to prepare for your visit

What should I ask the clinician?

• What else could be causing my symptoms? How did you rule those out?
• Do I meet the criteria for ADHD? Which type?
• Do you need to talk to a family member or see school records?
• What treatment options fit me, with and without medicine?
• How often will I see you, and who do I call with questions?

What if I am not diagnosed with ADHD?

That is still useful information. Ask what the clinician thinks is going on and what can help. Sleep, mood, anxiety and stress problems are all treatable. You may ask for a second opinion if you still have concerns.

Does a diagnosis mean I have to take medicine?

No. A diagnosis opens up choices. These include ADHD medicines, therapy and coaching, and everyday strategies. You decide with your clinician what fits your life and health.

When to get help

Make an appointment with your doctor if focus, restlessness or impulsive choices keep causing trouble at work, with money, in relationships or behind the wheel. Go sooner if these problems are new or getting worse, especially after age 60.

If you feel hopeless or have thoughts of harming yourself, call or text 988 to reach the Suicide and Crisis Lifeline any time. If someone is in immediate danger, call 911. For more ways to get support, visit Get help now.
