ADHD in Adults: Symptoms, Testing, and Navigating Diagnosis

While attention deficit hyperactive disorder (ADHD) symptoms often start in childhood, many individuals are diagnosed as adults, particularly women. Here, we explore common symptoms of ADHD in adulthood, the process for getting tested, and how to navigate a diagnosis, with insights from experts in the field.

Common Symptoms of ADHD

Approximately two-thirds of children with ADHD will continue to have symptoms throughout their adult lives, leading to adult ADHD. Data from the National Center for Health Statistics Rapid Surveys System found in 2023 that of the more than 15 million Americans with an ADHD diagnosis, more than half were diagnosed at age 18 or older.

There are three main subtypes of ADHD: predominantly inattentive, predominantly hyperactive, or combined-type ADHD. Depending on the type of ADHD, individuals will have some or all of the following symptoms:

  • Inattention – difficulty paying attention, completing tasks, and staying organized
  • Hyperactivity – excessive activity or restlessness, even in inappropriate times
  • Impulsivity – a lack of self-control, or acting without thinking

 

Without proper treatment and management, these symptoms can have a negative impact on an individual’s home, school, or work life.

Getting Diagnosed

If you are experiencing disruptive symptoms of ADHD, it may be beneficial to undergo testing. The World Health Organization offers a free, quick self-screening tool developed by a team of psychiatrists and researchers that asks a few questions about your typical behaviors and habits. The results produce a score which indicates if you may be a candidate for further ADHD testing.

While there is currently no single medical test that can diagnose ADHD, licensed medical professionals typically use the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), to assess an individual’s likelihood of having ADHD. The manual defines adult ADHD as an individual age 17 or older showing at least five persistent symptoms of inattention and/or hyperactivity-impulsivity, present since before age of 12, across two or more settings, and not better explained by another condition. The assessment will determine the type of ADHD an individual has, along with a severity of either mild, moderate, or severe. Once a diagnosis occurs, the provider will follow up with recommended resources and treatment options for managing ADHD symptoms.

Managing Symptoms

Current research suggests that a combination of medication and therapy is the best treatment option for ADHD. Support groups, coaching, and lifestyle changes can provide additional assistance in processing an ADHD diagnosis and managing symptoms. For example, individuals with ADHD may often feel easily distracted and have trouble focusing. Creating structure and routines within your schedule can be a helpful way to stay on task, remain organized, and succeed with time management.

Prioritizing a healthy lifestyle can also play a factor in managing symptoms:

  • Diet: Ongoing research suggests that eating a healthy diet with fruits and vegetables may lessen ADHD symptoms, and the Attention Deficit Disorder Association recommends avoiding caffeine, foods high in additives, refined carbs (like baked goods high in sugar), and unhealthy fats.
  • Exercise: Exercise, which triggers endorphin release and can boost energy, can be a helpful tool in managing symptoms.
  • Sleep: Prioritizing sleep health can help prevent exacerbated symptoms resulting from sleep disruption commonly experienced by adults with ADHD.

 

While these strategies don’t offer a cure for ADHD, working with a primary care provider or mental health provider to develop a personalized treatment plan can help manage symptoms long term.

Q&A With Expert Providers

Q: How can ADHD present differently in men and women?

A: The diagnostic criteria for ADHD are the same for men and women, and adults generally report similar core symptoms regardless of gender. However, women with ADHD are often more likely to develop coping strategies and adapt their behavior in ways that mask their difficulties. In other words, they may be struggling just as much internally while appearing to function well on the outside. This may help explain why men are diagnosed more often during childhood and adolescence, while many women do not receive an ADHD diagnosis until adulthood. We frequently see women who have managed their symptoms successfully for years, only to become overwhelmed after having children or during perimenopause. Hormonal changes, combined with increased demands, can make ADHD symptoms more noticeable and previously effective coping strategies less successful. If you feel chronically overwhelmed or burned out and wonder whether ADHD could be contributing, consider seeking an evaluation from a licensed psychologist. Effective treatment and support are available!

Q: What should adults keep in mind when testing for ADHD?

A: Research-based screening tools or self-assessments may assist in diagnosis, but they are limited in formalizing an official diagnosis. ADHD is a neurodevelopmental disorder, which affects how the brain grows and works. The onset of ADHD starts in early childhood. Therefore, for adults who may be undiagnosed, it is important to not only assess current symptoms, but also to consider inattention, hyperactivity, and impulsivity prior to age of 12. For any diagnosis, it’s important to schedule a consultation with a licensed mental health provider, psychiatrist, psychologist, or primary care provider.

Q: What are some effective tools and strategies to manage symptoms of ADHD?

A: For those experiencing cognitive dysfunction, the importance of diet and exercise cannot be overstated. Exercise is an important nonpharmacologic approach, as it enhances synaptic signaling, restores neurotransmitter imbalance, and stimulates brain healing. Recent studies have shown that low impact exercises such as swimming during pregnancy contribute to enhanced neuroplasticity and improved ADHD phenotypes for their children. We are made to move! Adults with attentional deficits may not tolerate traditional pharmacologic approaches; however, the persistence of symptoms such as poor time management, lacking organizational skills, and executive dysfunction may still jeopardize job security and relationships. Scheduling an evaluation to understand how your brain processes information is an important first step. Treatments such as psychotherapy, neurofeedback, tDCS, and neurophotobiomodulation may help restore cognitive performance and functional connectivity.
