Assessment & treatment
Adult ADHD
Plenty of adults reach their thirties or forties before anyone suggests ADHD — often after a child is diagnosed and something clicks. A proper assessment tells you what you are actually dealing with, and gives you a document you can take to a physician, an employer, or a university.

What the assessment covers
DSM-5-TR criteria
Current symptoms
Standardised self-report and observer measures covering attention, activity, and impulsivity as they present now.
Cognitive functioning
Testing of attention, working memory, and processing speed to separate ADHD from the conditions that mimic it.
Level of impairment
How much this is actually costing you at work, at school, and at home — the part that decides whether a diagnosis is warranted.
How it runs
The process
The assessment runs across several appointments: an intake interview, a testing session, and a feedback session where we go through the findings together. You receive a written report you can share with your family physician, psychiatrist, employer, or academic accommodations office.
Where a diagnosis is supported, we talk through what actually helps — which for most adults is a combination of skills work, environmental change, and a conversation with a prescriber about medication.
Before you book
Assessment fees are set per the Ontario Psychological Association schedule and are not covered by OHIP. Many extended health plans reimburse part or all of the cost under psychological services — worth checking your annual limit first, since an assessment can use most of it.
