How Is ADHD diagnosed in adults?

Diagnosing ADHD in adults is done using a variety of methods — interviews, medical history, and psychological tests and assessments. A diagnosis can also include a physical exam and blood tests to rule out underlying medical conditions that might mimic ADHD.

Most licensed providers will see you in person or online to evaluate your symptoms using clinical guidelines, such as the criteria in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), and various types of diagnostic methods and tests to gather the most precise information. Methods used can include:

A physical exam to rule out any underlying thyroid or seizure conditions that can mimic ADHD
A diagnostic interview to gather a detailed list of your current and past medical history and medications
An in-depth conversation about your symptoms; at times, you will not present with symptoms during your visit; for this, the provider must be very detailed
An ADHD symptoms checklist
Standardized behavior rating scales
Family member or a loved one interviews to learn more and if you agree
Cognitive ability testing to rule out a learning disorder
The Vanderbilt assessment scale: a 55-question assessment by reviewing the symptoms of ADHD. It also rules out underlying mental conditions, such as depression, anxiety, and conduct disorders.
Brain wave tests: A neuropsychiatric EEG-based assessment aid sends waves into your brain to measure the amount of activity. This test is usually for children under 17, but healthcare providers sometimes use it to confirm a diagnosis of ADHD in adults.

Psychological testing for ADHD diagnoses in adults

Diagnosing ADHD can be tricky since there’s no single exam or psychological test that determines if you have ADHD or not. Your healthcare provider might use multiple assessments to determine which ADHD disorder you have. Here’s a deeper look at some of the tests and criteria your provider might use.

Diagnostic interview

A diagnostic interview consists of a detailed conversation between you and your healthcare provider. You’ll be asked to discuss your past medical history, family history, and medications. Most importantly, you’ll be asked about your current condition, emphasizing your daily tasks and activities.

Family interview

Having a loved one close to you can help providers diagnose your ADHD. This can be your parents, siblings, partner, friend, or even a co-worker who has been around you for an extended period. If the person lives with you, it’s beneficial to give the healthcare provider a better understanding of the symptoms you’re having.

Test of Variable Attention (TOVA)

TOVA is a 22-minute neuropsychological test that screens for ADHD and measures the attention variables in a person. It’s done as a computer game that includes separate auditory and visual tests. People are visually shown 2 simple geometric figures and are asked to click a microswitch when the image is seen. The same concept is used for the auditory test; when the taker hears a specific sound, they’re directed to hit the microswitch.

TOVA should never be used as the only criteria for diagnosis.

Standardized behavior rating scales for psychological testing for ADHD in adults

With a multidimensional approach, these scales can be used as various forms of checklists with the guidelines of DSM-5’s underlying conditions and intended use for a third-party individual. This can be your boss, clinician, or partner. This helps providers to understand of your symptoms and comes in many variations, like:

Conners Adult ADHD Rating Scales

Conners Adults ADHD Rating Scales (CAARS) is one of the most popular tools for assessing ADHD that includes self-report and observer forms that usually take 15-20 minutes to complete. CAARS is issued in two different versions, a long and short, comprising measurements of ADHD symptoms.

The Behavior Rating Inventory of Executive Functioning

The Behavior Rating Inventory of Executive Function – Adult Version (BRIEF-A) includes 75 items that measure different aspects of environmental functioning. It uses 2 reports, a self-report and an information report. If the patient is unaware of their behaviors and has difficulty with self-monitoring, the provider only uses the information report.

Barkley Adult ADHD Rating Scales for psychological testing for ADHD in adults

The Barkley Adults ADHD Rating Scales – IV (BAARS-IV) was used to measure current and childhood symptoms. It includes a self-report and an other-report for partners, parents, siblings, or any close relative or friend. This conveniently reliable tool usually takes less than 10 minutes to complete.

Medical exam

A board-certified healthcare provider may also give you a medical exam and blood test to rule out any underlying issues that mimic ADHD. This will help rule out any thyroid issues, depression, anxiety, and others, including any past head trauma Some providers will also issue a urine drug screening test to rule out any substance abuse that could be contributing to ADHD-like symptoms.

Testing for other conditions

Learning disorders or other functionality disorders mimic ADHD, including autism, obsessive-compulsive disorder (OCD), dyslexia, language processing disorders, sleep disorders, and sensory processing disorders. Healthcare providers will determine if other types of psychological testing are needed after your initial consultation.
