Adult ADHD is a lasting pattern of inattention, hyperactivity, or impulsivity that makes it hard to function in at least two areas of life, such as work and home. Diagnosis belongs with a physician, psychiatrist, or psychologist. Therapy, including cognitive behavioral therapy, helps you build skills for focus, organization, and daily tasks.
Key takeaways
The National Institute of Mental Health (NIMH) describes attention deficit hyperactivity disorder (ADHD) as "a persistent pattern of inattention and/or hyperactivity and impulsivity that makes it hard to function in at least two areas of life." NIMH also notes that symptoms begin in childhood and usually continue into the teen years and adulthood.
In its longer guide, ADHD: What You Need to Know, NIMH notes that ADHD is well known in children and teens, "but many adults also have the disorder." Much of what people read about ADHD is about kids. This guide is for the adult who has started to wonder whether it fits them.
More common than many people think. A 2024 report in the CDC journal Morbidity and Mortality Weekly Report (MMWR) estimated that 15.5 million U.S. adults (6.0 percent) had a current ADHD diagnosis in 2023, based on a national survey. Among those adults, 62.8 percent were ages 25 to 49. The report's summary is direct: "ADHD affects many adults."
The same report found that more than one half of adults with ADHD (55.9 percent) received their diagnosis during adulthood. If you are in your thirties or forties and only now asking the question, you are in good company.
NIMH groups ADHD symptoms into three areas. Inattention means "difficulty paying attention, staying on task, or being organized." Hyperactivity means "excessive activity or restlessness, even at inappropriate times." Impulsivity means "acting without thinking or having trouble with self-control." NIMH adds that adults with ADHD "often have a history of problems with school, work, and relationships," and that they "may also be irritable, have a low tolerance for frustration and stress, or experience frequent or intense mood changes."
In everyday adult life, that can look like:
Everyone has some of these some of the time. A list like this is a reason to ask a professional, not a diagnosis.
ADHD does not start in adulthood. NIMH notes that symptoms must begin in childhood, before age 12, and that "adults must have shown symptoms much earlier." Many adults managed in school with structure, extra effort, or support from family, and the strain only became clear when work, a household, or parenting added more to track. Others were never evaluated as kids.
For adults, NIMH explains that the evaluation looks for five (instead of six) symptoms of inattention or of hyperactivity and impulsivity. A clinician may also ask to talk with family or friends who know you well.
Diagnosis is a medical and psychological evaluation, not something a quiz or an article can settle. NIMH notes: "Primary care providers sometimes diagnose and treat ADHD, or they may refer the person to a mental health professional." For adults, that usually means a physician, a psychiatrist, or a psychologist who does ADHD evaluations. NIMH also notes that symptoms must be present in two or more settings, such as at home, at work, or with friends.
Foundations counselors do not diagnose ADHD. If you want a formal evaluation, start with your physician. You do not need a diagnosis to begin counseling, and counseling can continue alongside an evaluation.
This is one of the most common questions adults ask, and it is a fair one. NIMH notes that "stress, sleep disorders, anxiety, depression, and other physical conditions or illnesses can cause similar symptoms to those of ADHD." NIMH also notes that ADHD often occurs alongside other conditions, which can make each one harder to diagnose and treat. That overlap is one more reason the evaluation belongs with a physician or psychologist. Our guide Is It ADHD or Anxiety? walks through the differences, and our anxiety counseling page explains how counseling helps with worry.
Therapy does not diagnose ADHD or replace medical care. It helps with the daily work of living with it. NIMH says cognitive behavioral therapy (CBT) "helps a person become aware of attention and concentration challenges" and builds skills for focus, organization, and completing daily tasks, such as breaking large jobs into smaller steps. NIMH adds that "adding therapy to an ADHD treatment plan can help some people better cope with daily challenges," build confidence, and manage impulsive or risky behavior, and that therapy is especially helpful when ADHD occurs alongside anxiety, depression, or substance use disorders.
In counseling, adults often work on:
Results vary from person to person. Therapy works best as one part of a plan you build with your care team.
NIMH notes that "effective treatment often involves a combination of elements," which can include medication, usually stimulant medication, and psychotherapy. The CDC report found that about one third of adults with ADHD took a stimulant medication in the previous year. Whether medication is right for you is a decision for you and your physician or psychiatrist. Foundations counselors provide talk therapy only and do not prescribe or advise on medication.
Sixteen Foundations counselors are listed on our ADD and ADHD therapy page, and the ages each counselor sees vary by counselor. Counseling focuses on skills, routines, stress, and the relationships ADHD touches. It does not include ADHD testing or medication. Sessions are in person in Fort Collins, Loveland, and Windsor, or online in Colorado. Your first meeting with your matched counselor is a free consultation, and if that counselor is not the right fit, our Counselor Match Guarantee means we will find another counselor who is.
The National Institute of Mental Health groups signs into inattention, hyperactivity, and impulsivity. In adults that can look like missed deadlines, losing focus in conversations, restlessness, impulsive choices, and frustration or stress. Adults with ADHD often have a history of problems with school, work, and relationships. Only an evaluation can tell you whether it is ADHD.
A 2024 CDC report estimated that 15.5 million U.S. adults (6.0 percent) had a current ADHD diagnosis in 2023, and 62.8 percent of those adults were ages 25 to 49. More than one half (55.9 percent) received their diagnosis during adulthood, so finding out later in life is common.
A physician, psychiatrist, or psychologist who does ADHD evaluations. NIMH notes that primary care providers sometimes diagnose ADHD or refer you to a mental health professional, and that symptoms must have started before age 12. Foundations counselors do not diagnose ADHD, so start with your physician if you want an evaluation.
No. You can start counseling based on what you notice, such as trouble focusing, missed deadlines, or feeling scattered, and work on those challenges right away. If you want a formal evaluation or are considering medication, talk with your physician or a psychiatrist. Counseling can continue alongside that process.
According to NIMH, cognitive behavioral therapy helps a person become aware of attention and concentration challenges and build skills for focus, organization, and daily tasks. Therapy can also help with stress, confidence, relationships, and anxiety or depression that show up alongside ADHD. Results vary from person to person.
That is a question for your physician or a psychiatrist, not your counselor. NIMH notes that effective ADHD treatment often combines elements, which can include medication and psychotherapy. Foundations counselors provide talk therapy only and do not prescribe or advise on medication. Do not change any medication without talking to your prescriber.
