ADHD Assessment

What is ADHD?


Attention-Deficit Hyperactivity Disorder (ADHD) is a neurocognitive disorder that involves a consistent pattern of difficulty (identifiable before the age of 12) regulating one’s attention, emotion, and behaviour. According to The Diagnostic and Statistical Manual of Mental Disorders (DSM-5), ADHD is a complex psychiatric condition that often persists over a lifetime. Symptoms can vary amongst individuals and present differently for boys, girls, men, and women, but fall into three categories:


  • Predominantly Inattentive Presentation — the person has difficulty with organizing or finishing a task. They find it hard to pay attention to details and find it difficult to follow instructions or conversations.

  • Predominantly Hyperactive-Impulsive Presentation — the person finds it hard to keep still. They fidget or talk a lot. The person is restless, impulsive and could interrupt others at inappropriate times. They have difficulty waiting their turn and find it hard to listen to directions.

  • Combined Presentationa person whose experiences symptoms equally in both presentations described above.

ADHD usually becomes problematic for an individual once the symptoms begin to interfere with the quality of social, academic or workplace functioning. The diagnosis of ADHD requires a careful age-appropriate assessment of attention, executive functioning, and behavioural impairment. You can learn more about ADHD and its diagnosis at

What is the process of an ADHD Assessment?


Before the first session, we will send you a background questionnaire to complete prior to your assessment. Other elements of the assessment include:

  • Interview to collect developmental history

  • Computerized Testing (could be done at our clinic or remotely)

  • Structured Clinical Interview conducted during a two-hour meeting that could be done in-person or remotely

  • Normed Questionnaires to be completed by you and an observer.

  • Review of collateral information such as grade school report cards and other assessment reports.

What is the outcome of an ADHD Assessment?


  • An understanding of your attention and behavioural functioning.

  • The diagnosis of ADHD if present.

  • A list of recommendations for improving performance at home, work, and school.

  • A referral to our consulting physician to learn more about pharmacological interventions available and their pros and cons.

Following the assessment, the psychologist meets with you to review the results, recommendations, and next steps.

Our fee for an Adult ADHD assessment is $2000.
