Why Consider an Adult ADHD Assessment in Cambridge?

Many adults go through life compensating for undiagnosed ADHD — often without realising what’s contributing to their daily difficulties. Common experiences may include: ongoing disorganization, trouble with planning or time management, impulsive decisions, or challenges sustaining attention even when you care about the outcome.

A structured ADHD psychological assessment offers you:

  • Clarity about whether ADHD might explain your experiences

  • A formal diagnosis (if criteria are met), which can support treatment, workplace accommodations, or academic adjustments

  • Detailed feedback and recommendations tailored to your strengths and challenges

  • Peace of mind — whether or not ADHD is diagnosed, you’ll understand yourself better

What to Expect from the Assessment Process

Our ADHD assessment follows a supportive, evidence-informed process that aligns with best practices for adult evaluations in Ontario.

1. Initial Contact & Intake

We begin with an intake call or online form where you share your main concerns — for example, difficulties with focus, organization, productivity, or distractibility. We also gather relevant background information and schedule your assessment appointment.

2. Clinical Interview & Questionnaires

In your appointment, you’ll meet with a registered clinician who will explore your life history, symptom patterns, work and education background, and daily functioning. Standardised ADHD questionnaires will be completed to help measure attention, impulsivity, and executive functioning.

A core part of the assessment is understanding whether symptoms began in childhood and have continued into adulthood, a key criterion in adult ADHD evaluations.

3. Additional Testing (If Required)

Depending on your story, we may include further cognitive or executive-function tests. These help clarify your cognitive profile and distinguish ADHD traits from other factors like anxiety, learning differences, or memory concerns.

4. Feedback & Report

Once all data is gathered, your clinician prepares a comprehensive report that:

  • Summarises the assessment findings

  • Indicates whether diagnostic criteria for ADHD are met

  • Highlights any other relevant factors

  • Offers personalised recommendations for next steps

We then meet for a feedback session where you can ask questions and review results together.

5. Next Steps & Ongoing Support

If a diagnosis of ADHD is confirmed, we help you explore your options — including therapy, skills coaching, lifestyle strategies, or referrals for medication evaluation as needed. Even if ADHD is not diagnosed, the insights you receive can be invaluable for understanding and improving focus, organisation, and daily functioning.
