Symptoms of ADHD in Adults

Adults with ADHD usually show patterns of specific ADHD symptoms, including:

  • Poor time management
  • Unable to complete or focus thoroughly on tasks
  • Impulsiveness
  • Restlessness
  • Poor social communication

The DSM-5 lists three different presentations of ADHD – inattentive, hyperactive-Impulsive, and combined, explained below: 

Inattentive ADHD

Adults with inattentive ADHD may have trouble staying on task and experience five or more of the following symptoms for at least six months: 

  • Often fails to give close attention to details or makes careless mistakes in school or job tasks
  • Having problems staying focused on lessons or activities for a long time. (lectures, work tasks, and sustainable tasks) 
  • Does not seem to engage and stay attentive when talking and tends to drift away in thoughts 
  • Does not follow through on instructions, complete tasks, chores, or job duties, and loses focus after starting
  • Often has troubles with organizing activities and staying on task

  • Tends to lose things needed for jobs or daily life
  • Often easily distracted
  • Forgetting daily tasks 

Hyperactive-Impulsive ADHD

Adults with hyperactive-impulsive ADHD may be impulsive and struggle with thinking through the consequences of their actions. If you have hyperactive-impulsive ADHD, you will likely experience five or more symptoms for at least six months: 

  • Difficulty staying seated for an extended period (in the workplace and in meetings) 
  • Often fidgets and squirms while sitting down 
  • Usually leaves situations in certain areas when it is not appropriate (hard time staying seated during a board exam)
  • Unable to do leisure activities alone or quietly 
  • Always “on the go,” and does not seem to take things slowly
  • Excessive talking 
  • Interrupts others when conversing and does not let others finish their sentences 
  • Often cannot wait for an extended period or their turn (waiting in long lines) 
  • Often interrupts others (using others’ personal space and items without asking) 

Combined ADHD

A mental health provider often diagnoses this type of ADHD for patients experiencing five or more inattentive and hyperactive/impulsive symptoms within the last six months.

Psychological Tests for Diagnosing ADHD

Diagnoses of ADHD can be quite tricky since there’s no single psychological test that determines if you have ADHD or not. Your healthcare provider might use multiple assessments to determine which ADHD disorder you have. 

Most licensed providers on Klarity will join you on a video call to evaluate your symptoms by using the clinical guidelines such as the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria and various types of diagnostics to gather the most precise information that might include: 

  • A physical exam to rule out any underlying thyroid or seizure conditions that can mimic ADHD
  • A diagnostic interview with 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 
  • Further information about your symptoms from a family member or a loved one that is close to you 
  • Conduct cognitive ability test to rule out any learning disorders 
  •  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 Assessments 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. 

Test of Variable Attention

TOVA is a 22-minute neuropsychological test that screens for ADHD and measures the attention variables in the patient. This computer game includes both auditory and visual tests. In this game, patients are visually shown two simple geometric figures and are asked to click a microswitch when the image is seen. The same concept is behind the auditory test; when the patient hears a specific sound, they will be directed to hit the microswitch. 

This test should never be used as the only criteria for diagnosis. 

Diagnostic Interview

A diagnostic interview consists of a detailed conversation between you and your healthcare provider. You will be asked to discuss your past medical history, family history, and medications. Most importantly, you will be asked about your current history, 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, or even a co-worker who has been around you for an extended period. If the person lives with you, this is also beneficial since this gives the healthcare provider a better understanding of the symptoms you are experiencing. 

Standardized Behavior Rating Scales

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 with appropriate understandings 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) comprises 75 items that measure different aspects of environmental functioning. This comes in two reports, a self-report and an information report. If the patient is unaware of their behaviors and has difficulty with self-monitoring, the provider would only use the information report.

Barkley Adult ADHD Rating Scales

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

Medical Exam

A board-certified healthcare provider would additionally perform a medical exam to rule out any underlying issues that mimic ADHD by doing a blood test. This will help rule out any thyroid issues, depression, anxiety, and many more, including any head trauma in the past. 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

It has been proven that patients could have a learning disorder or other functionality disorders mimicking ADHD. These can be autism, OCD, dyslexia, language processing disorders, sleep disorders, and sensory processing disorders. Healthcare providers on Klarity will determine if other types of psychological testing is necessary after your initial consultation. 

Who is Qualified to Diagnose ADHD

A board-certified physician, like a mental health professional, primary care provider, psychologist, or physiatrist, can diagnose ADHD and provide medications. Providers on Klarity are licensed and certified to give patients a diagnosis of their mental health symptoms, including ADHD.
