How to get diagnosed with ADHD as an adult

Signs you might have ADHD

Attention-deficit/hyperactivity disorder (ADHD) is classified as a neurodevelopment disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR). It’s characterized by a persistent pattern of symptoms spanning inattention, hyperactivity, and impulsivity.

Depending on your specific symptoms, you can be diagnosed with predominately inattentive ADHD, predominately hyperactive-impulsive ADHD, or a combined presentation.

According to the diagnostic criteria, inattentive ADHD symptoms include:

• Often missing details or making careless mistakes at work, school, or during other activities
• Often having trouble staying focused during tasks, conversations, or long stretches of reading
• Often spacing out instead of listening, even when there’s no obvious distraction
• Often struggling to follow instructions or finish chores, projects, and other tasks without getting sidetracked
• Often having difficulty organizing tasks, managing time, meeting deadlines, or keeping track of belongings
• Often avoiding or putting off tasks that require sustained mental effort, such as filling out forms or sorting your email
• Often losing things you need, such as keys, your phone, glasses, or paperwork
• Often getting distracted by your surroundings or by unrelated thoughts
• Often forgetting everyday responsibilities, such as doing chores, returning texts, paying bills, running errands, or keeping appointments

Hyperactive and impulsive ADHD symptoms include:

• Often fidgeting, tapping your hands or feet, or squirming in your sweat
• Often getting up in situations where you’re expected to remain seated
• Often feeling restless, like you’d rather be running, climbing, or moving
• Often having trouble doing quiet leisure activities
• Constantly feeling “on the go” or uncomfortable sitting still for long periods
• Often talking excessively
• Often blurting out answers or finishing other people’s sentences
• Often having difficulty waiting for your turn, such as in line or during a game
• Often intruding on others, like butting into conversations, taking over what they’re doing, or using their possessions without asking

But these symptoms alone aren’t an automatic sign you have ADHD, emphasizes Hanselman. In order to be diagnosed with ADHD as an adult:

• You need to experience five or more symptoms from either category for at least 6 months
• Several of the symptoms must have been present before age 12
• Several of the symptoms must show up in at least two areas of your life (such as work, home, school, etc.)
• And the symptoms must interfere with your social, academic, or professional functioning

It’s also important that your symptoms can’t be better explained by another condition like depression, anxiety, PTSD, or schizophrenia, all of which have notable overlap with ADHD, Hanselman notes. That’s why it’s so important to talk to a professional if you suspect you have ADHD. They can assess the full picture of your experience beyond a checklist and explore a range of explanations.

“ADHD can vary so much from person to person,” Hanselman says. “Even the core symptoms most people are aware of can show up differently in different people and scenarios, and it’s hard to untangle everything yourself.”

Who can diagnose ADHD in adults?

Several different types of providers can diagnose ADHD in adults, but it’s not always clear where to start or who might be the best fit for you, says Maddy Brener, Psy.D., licensed clinical psychologist at Thriveworks. Guidelines and restrictions vary state to state, but generally, both physicians and other mental health professionals can evaluate ADHD to some degree.

According to Dr. Brener and Hanselman, a diagnosis may come from:

• Primary care providers: Just like a pediatrician can diagnose ADHD in childhood, your main doctor may be able to evaluate you as an adult and prescribe you medication if they decide it’s part of the treatment plan. Or, if they’re uncertain, they can refer you to a mental health or ADHD specialist.
• Psychiatrists: These medical doctors specialize in treating mental health, conducting comprehensive psychological evaluations, providing formal diagnoses, and prescribing medication. In some cases a psychiatric nurse practitioner can also assess and treat ADHD, depending on their training and the state they practice in.
• Licensed clinical psychologists: Like psychiatrists, psychologists are doctoral-level mental health professionals who are trained to evaluate and diagnose mental health conditions, including ADHD. They tend to provide therapy and generally can’t prescribe medication.
• Other licensed mental health professionals: Some master’s-level mental health professionals like therapists, counselors, and social workers may also have diagnostic privileges based on extra training or supervision. Often, these providers will indicate on their profiles if diagnosing ADHD is within their scope. If not, you can always ask directly.

While it can be helpful to find an ADHD specialist to evaluate you, there is no official ADHD-specific qualification that’s required to diagnose someone. That’s why many people start with their primary care provider or their current therapist. But if you’ve gone that route and don’t feel like your symptoms are being taken seriously, it may be worth checking in with a specialist.

“Your PCP might be able to diagnose it in theory, but a specialist may be the one to actually recognize it based on your symptom presentations or advanced testing,” Hanselman explains.

What does getting diagnosed with ADHD actually involve?

First, let’s clear up a common misconception: There is no single, definitive “ADHD test.”

“Many people seem to think there’s a quick way to evaluate whether or not you have ADHD, but it’s not that simple,” Hanselman says.

Instead, providers usually diagnose ADHD from a few angles. The exact method will depend heavily on both you and your provider, and so will the timeline. “It could take a few sessions, a month, or maybe longer,” Dr. Brener says. That’s because there’s generally a lot of ground to cover, plus “you’re at the mercy of your schedule, the clinician’s schedule, what insurance allows, what’s available in your area—all of those bureaucratic and human limitations.”

With that in mind, here’s what the process typically entails:

Initial intake

Regardless of which provider you start with, your initial conversation will likely start with a discussion about your symptoms and what’s bringing you in specifically. “Why now? What’s bothering you enough that you finally took the step to see someone?” Hanselman says. This can be a really helpful clue with ADHD, because often, certain life circumstances—like starting or graduating college, a new job, and other transitions—can ramp up symptoms.

If you’re specifically pursuing the question of ADHD, your intake forms might include filling out symptom checklists, self-report scales, or other screeners—such as one modeled off the DSM criteria or something more targeted. Or it might be more of a free-flowing conversation about your symptoms.

Technically, this can be all it takes for an initial diagnosis and treatment plan, Hanselman says. But adult ADHD is difficult to diagnose and it’s not generally considered responsible practice to rush through the process or jump straight to treatment, especially medication. Typically, providers take at least a few more steps.

Information gathering

Remember, adult ADHD hinges on having symptoms that started in childhood, so providers tend to rely on more than just self-report to see the whole picture. This often includes speaking to people who know you well and can speak to your symptoms over the course of your life, particularly in childhood.

“Sometimes I’ll send screeners to the person’s parents to ask what they were like as a child or ask them to look for notes in old report cards,” Hanselman says. “It can feel like a ridiculous thing to do as a grown adult, but sometimes it’s the best we got.”

Depending on which provider you started this conversation with, they might also confer with others on your team, Dr. Brener adds—like your psychiatrist calling your therapist for their impressions, for example, or your psychologist recommending bloodwork or trauma screening to rule out other causes.

Neuropsychological evaluation and testing

While specialized testing is not required for an ADHD diagnosis, it may be useful in certain cases. For instance, some people are extra sensitive to medication, Dr. Brener says, and want to take additional steps to support a diagnosis before starting a prescription. Other times, people seek it out as a second opinion if they or another provider suspect ADHD.

It can sometimes be hard to distinguish ADHD from other concerns, so additional evaluation can clear up ambiguity. “A person may not have collateral to paint a picture of their symptoms in childhood,” Dr. Brener says. “Or they may have memory challenges, possibly from trauma.” By adulthood, you could also have some effective coping mechanisms or masking abilities in place, Hanselman adds, which can make symptoms less obvious during a standard appointment.

Neuropsychological testing for ADHD typically involves working one-on-one with a trained examiner—sometimes your provider in their office, or sometimes a specialist in an outside clinic. They’ll guide you through a series of assessments, questionnaires, and standardized tasks to evaluate your brain’s cognitive functions, such as attention, memory, executive functioning, motor skills, and general intelligence. These may include computer-based games, real-world puzzles, pen and paper exercises, or verbal tasks.

“There are a whole battery of tests to piece together how your brain works and if it aligns with what we know about ADHD,” Dr. Brener says.

Because they’re considered more “objective” measurements than, say, a clinical interview, your insurer or prescriber may require this kind of testing before covering or prescribing certain ADHD medications, including controlled substances like Adderall, Dr. Brener says. Similarly, you may need it for documentation when applying for accommodation or disability benefits.

Can you get diagnosed with ADHD online?

It is possible to go the telehealth route to get diagnosed with ADHD as an adult, but that diagnosis will always include seeing a licensed provider—not simply taking an “online ADHD test”.

Searching for an “adult ADHD test” online will often lead you to informational surveys and quizzes, including from places like Mental Health America, Attention Deficit Disorder Association, and Psychology Today. While these can be a helpful starting point to discuss with your provider, it’s important to remember that it’s only one part of the picture.

That said, there are online paths to an ADHD diagnosis. Many licensed providers can evaluate and diagnose through telehealth, depending on where you live and their scope of practice. The process would look similar to the IRL path described above—just with virtual sessions and a few caveats. “Telehealth is a very valid modality that has made mental health care more accessible, but there are certain limitations to keep in mind,” Dr. Brener says.

First, if you’re interested in neuropsychological testing, you may have fewer options. “Some of the tasks involve literally sitting in a room with a clinician and working with physical materials,” Dr. Brener says. And while remote options exist, you may not find a direct equivalent to in-person evaluation.

Getting certain ADHD medications online can also be tricky. Before the COVID pandemic, practitioners couldn’t prescribe schedule II-V controlled substances (such as Adderall) without conducting an in-person evaluation. But the DEA and HHS loosened the rules during the public health emergency, allowing authorized providers to prescribe if they met certain criteria—and those telemedicine flexibilities are still in place through the end of 2026. That said, some states still have restrictions on prescribing controlled substances via telehealth.

Finally, be wary of any services that promise an ADHD diagnosis in the advertising, reach one based on limited information, or seem eager to prescribe medication in your first session, Hanselman says. On the other hand, she says good signs include licensed clinicians with ADHD experience, a clearly stated treatment philosophy, and meaningful follow-up care.

What does having a diagnosis mean?

While you don’t need an ADHD diagnosis to start managing your symptoms with therapy, self-guided tools, and lifestyle adaptations, there are some potential advantages to being diagnosed.

Broadly speaking, a diagnosis acts as a map for treatment, Hanselman says. Experts have established evidence-based guidelines for treating ADHD, so a diagnosis can inform what your provider recommends. That may include medication like Adderall or Vyvanse, which typically require a diagnosis of ADHD.

On a practical level, an ADHD diagnosis can also open the door to certain accommodations or benefits depending on your location, school, workplace, and severity of your symptoms. As a recognized disability and medical condition, ADHD may qualify you for protections under the Americans with Disabilities Act, time off through the Family and Medical Leave Act, or short-term disability through your employer.

Lastly, there’s a psychological component to diagnoses as well. Hanselman points to the title of a classic self-help book for adults with ADHD, You Mean I’m Not Lazy, Stupid or Crazy?!: “That pretty much sums up a lot of people’s experience when they finally have an explanation for what they’ve been going through,” she says.

Frequently asked questions (FAQs)

Can my primary care doctor diagnose ADHD?

Possibly. Many primary care physicians can evaluate and diagnose ADHD, prescribe medication when appropriate, or offer initial diagnostic impressions before referring you elsewhere. Because adult ADHD can be difficult to identify and distinguish from other conditions, some experts recommend seeing a licensed mental health provider or ADHD specialist instead.

What is required to diagnose someone with ADHD?

To diagnose someone with ADHD, a qualified provider like a primary care doctor, psychologist, or psychiatrist will evaluate them according to the criteria found in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, or DSM-5-TR. That typically involves reviewing current symptoms, childhood history, how difficulties show up across settings, and how much they interfere with daily life. Sometimes, more specialized psychological and cognitive testing is recommended or required when the picture is unclear or additional documentation is needed.

What happens after an ADHD diagnosis?

After an ADHD diagnosis, treatment usually begins with a plan tailored to your needs, which may include medication, therapy, practical strategies to support executive functioning, and other lifestyle changes. Your provider will also likely recommend continued follow-up appointments to see what is helping, adjust treatment, and address related concerns.

Does an ADHD diagnosis qualify you for ADA accommodations?

ADHD is a recognized disability under the American With Disabilities Act, but a diagnosis alone doesn’t automatically guarantee accommodations. You generally need to show that your symptoms substantially limit a major life activity, and the support you receive will depend on your specific needs, documentation, and the policies of your workplace or school.

Is it too late to get diagnosed with ADHD as an adult?

No, it’s never too late to get diagnosed with ADHD—but it may present certain challenges. Because symptoms must have been present before age 12, providers may ask about your childhood, send questionnaires to a parent or relative, review old report cards, or look for other evidence of early difficulties. But even when those records are limited, a clinician can rely on other tools to reach a diagnosis.

How much does an ADHD evaluation cost?

It’s hard to say—it can heavily depend on the provider, the type of evaluation, and your insurance coverage. Some plans cover ADHD assessments or neuropsychological testing, though some may require a referral or additional proof of medical necessity. Other plans may only cover part of the cost or none at all. Out of pocket, specialized neuropsychological testing can cost anywhere from hundreds to thousands of dollars. That said, these advanced diagnostic tools aren’t required for an ADHD diagnosis, though they can be helpful in certain cases.
