Adult ADHD assessment at Positive Mind Wellness

What is an ADHD Assessment?

An ADHD assessment is a thorough method of screening for ADHD in adults. It combines psychometric tests, collateral information, and clinical interviews with a psychologist for you and others close to you that may provide useful insight into your functioning.

Our assessment also provides differential diagnosis. This means that our assessment is designed to differentiate between an ADHD diagnosis and other conditions with overlapping symptoms (e.g. anxiety, depression, burnout, OCD, etc.). Our assessment also includes evaluation for some of these conditions and others.

What Happens During an ADHD Assessment?

Our detailed ADHD assessment involves a few steps to give us a full picture of your overall functioning and areas where you may be struggling to cope. We offer both in-person and virtual (video) assessments over a secure teleconferencing platform, allowing us to provide services throughout Ontario.

We meet with you and anyone in your support network to understand your daily functioning. Not everyone is impacted by ADHD in the same way, so it’s important for us to learn what areas you think are being affected.

Our psychologist will interview you about your personal history, covering areas such as education, employment, family, and medical history. You will also fill out self-report questionnaires. Additionally, the psychologist will conduct psychological testing.

To have a fuller picture of how you have functioned in multiple areas over different periods of time, it is helpful (but not mandatory) to have collateral information. This includes medical records, school report cards, letters from family members, and any other psychological or psychiatric assessment reports.

After the assessment, you’ll receive the psychologist’s detailed report that includes:

  • DSM 5 psychological diagnosis(es)
  • education about the diagnosis(es)
  • Targeted evidence-based treatment options
  • Self-directed and lifestyle changes

Our psychologist will schedule a follow-up appointment with you to discuss the results of your assessment. You will be able to ask any questions about the conclusion and recommendations about the final report.

Who Can Benefit from an ADHD Assessment?

If you’ve noticed that your work, relationships, and other areas of life are affected by your inattention, difficulty focusing, hyperactivity, or impulsivity but do not have an official ADHD diagnosis, consider finding out whether you might have been undiagnosed or misdiagnosed.

Our ADHD assessment is designed for adults, so anyone ages 18 and up who suspects they might have undiagnosed ADHD can book an assessment with us.

ADHD does not always look like a restless child who cannot sit still. Plenty of adults tell us the same things. “I did well in school, so it cannot be ADHD.”

“I am successful at work. I am not hyperactive, and I always assumed it was anxiety.”

None of these rule ADHD out. Many people cope for years through effort, long hours, and strict routines, and were never identified as children. In adults, ADHD often shows up as inattention, inner restlessness, and executive function struggles instead of obvious activity.

Adult discussing symptoms during an ADHD assessment

Many adults come to us sensing that focus and organization take more effort than they should. Trouble focusing at work, constant procrastination, and time management struggles are common reasons people book. Forgetfulness, unfinished tasks, and emotional overwhelm add up over time. An assessment helps you find out if ADHD is the cause and what to do about it.

Plenty of adults were never identified as children, especially those who did well in school or built careers on hard work and routine. You may have started questioning ADHD after a child or sibling was diagnosed, or once old coping strategies stopped working. A late diagnosis can explain lifelong patterns of disorganization and procrastination, and it opens the door to real support.

ADHD often looks different in women, which is one reason it gets missed for so long. Symptoms can show up as inattention, emotional overwhelm, and burnout rather than obvious hyperactivity, and they are sometimes mistaken for anxiety or depression. If you have spent years feeling like you are falling behind despite real effort, an assessment can finally bring clarity.

Advantages of Seeking an ADHD Assessment

When you’ve been living with undiagnosed ADHD, it can be hard to see how your life is being impacted and can be helped with the right knowledge and coping strategies. Getting an adult ADHD assessment is the first step in recognizing where you’re struggling so you can begin to increase your self-awareness and confidence, improve your relationships, enhance your work performance, manage stress more effectively, discover how to compensate for your challenges, and improve your overall well-being.

Signs You May Need ADHD Testing

ADHD shows up differently from one person to the next, and the signs are easy to write off as personality, stress, or a lack of effort. If several of the patterns below feel familiar, have lasted for months, and appear in more than one area of life, ADHD testing may be worth considering. These are the signs we look at most closely.

Inattention

Focus problems are usually the first thing people notice. You start with good intentions, then drift, lose track, or leave things unfinished:

  • Difficulty staying focused
  • Easily distracted
  • Forgetfulness
  • Losing items
  • Difficulty finishing tasks
  • Trouble following instructions

Hyperactivity

This can show up as physical restlessness, or as an inner sense of unease that never quite settles:

  • Restlessness
  • Difficulty sitting still
  • Feeling constantly “on the go”
  • Fidgeting

Impulsivity

Affects decisions, emotions, and social moments, often before you have had time to think:

  • Interrupting
  • Acting before thinking
  • Emotional outbursts
  • Difficulty waiting

Executive Function Challenges

Executive function is where ADHD quietly disrupts daily life and makes planning and follow through feel harder than they should:

  • Poor time management
  • Disorganization
  • Procrastination
  • Difficulty planning
  • Trouble prioritizing

Everyone deals with some of these from time to time. What matters is how often they happen, how strong they are, and how much they affect your work, relationships, and daily life. When these signs keep getting in the way, an ADHD assessment can tell you if ADHD is the cause and what will help next.

FAQs – ADHD Assessment

In children, ADHD assessment is conducted through tests by family doctors, nurse practitioners, paediatricians, etc. with a diagnosis based on criteria found in the DSM-5. The ADHD assessment is comprehensive with detailed reports from doctors, parents, and teachers. A physical exam is used to rule out other medical issues, and, in complex cases, a specialist is consulted.

Yes. One aspect of an ADHD test is to rule out other conditions that may be mistaken for ADHD. Other conditions that may be interpreted as ADHD include anxiety disorders, feelings of despondency, sleep disruptions, trauma/PTSD, learning disabilities, or difficulties with sensory processing. As 20% of children may be misdiagnosed, it is vital to have a professional evaluation.

Sorry, no. While this is a condition that begins in children, approximately 3% to 6% of adults worldwide present symptoms of adult ADHD. If left untreated, adult ADHD may result in problems on the job, in relationships, and in daily life.

After ruling out alternative conditions like anxiety or bipolar disorder, a person is evaluated by a specialist. Probing interviews, symptom checklists, and a review of scholastic and medical history is done to determine symptoms appeared earlier than age 12.

Most assessments take several hours of clinical time across one or more visits. That usually includes an interview, questionnaires, and structured testing. You receive a detailed psychological assessment report afterward, often within a couple of weeks.

Yes. A formal diagnosis and written report can support requests for accommodations at college, university, or work, such as extra time on exams, note taking support, or a quieter workspace. We include practical recommendations you can share with them.

An ADHD assessment completed by a psychologist is usually not covered by OHIP. Many extended health and workplace benefit plans do reimburse psychological services, in part or in full. Coverage depends on your plan. Contact us for more information.

The cost depends on the scope of the assessment and the clinician you see. You can view current fees on our Therapy & Wellness Prices page, and we are glad to confirm what your assessment includes before you book.

A diagnosis is the starting point, not the finish line. We walk you through the next steps after diagnosis, from therapy and skills training to accommodations, referrals, and medication conversations with your physician, so you leave with a clear plan.
