ADHD Assessments in Ottawa and Gatineau for Adults and Children
Comprehensive ADHD Testing for All Ages
Psychologists in our network provide in-depth ADHD assessments for both children and adults in Ottawa and Gatineau, helping clients better understand attention-related difficulties and access appropriate support. Whether you’re a parent seeking clarity for your child, or an adult who suspects ADHD may be affecting your work or daily life, a formal evaluation can be a critical step toward improved functioning and well-being.
What Is ADHD?
Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition characterized by patterns of inattention, hyperactivity, and/or impulsivity that interfere with daily functioning. While commonly diagnosed in childhood, many individuals go undiagnosed until adulthood. A formal psychological assessment is the most reliable way to determine whether symptoms meet diagnostic criteria and to rule out other conditions.
Why Choose an ADHD Assessment at One of Our Ottawa or Gatineau Clinics
For Children and Teens:
-
Difficulty focusing at school or completing homework
-
Frequent restlessness, impulsivity, or emotional outbursts
-
Trouble following instructions or staying organized
For Adults:
-
Chronic disorganization, procrastination, or poor time management
-
Difficulty sustaining attention at work or in conversations
-
A longstanding history of academic or occupational underachievement
Getting assessed can help clarify whether these challenges are related to ADHD or other underlying issues such as anxiety, learning disabilities, or executive functioning difficulties.
ADHD Assessment Process
Psychologists in our network conduct comprehensive evaluations tailored to each client’s age, background, and concerns. Our ADHD testing process typically includes:
-
A thorough clinical interview conducted in person or via video conference
-
Standardized ADHD rating scales and behavioural questionnaires
-
Cognitive testing to assess attention, memory, and executive functioning
-
Review of academic, developmental, and medical history
-
Differential diagnosis to rule out other conditions
Once the assessment is complete, clients receive a detailed report outlining diagnostic impressions, treatment recommendations, and—when applicable—accommodations for school or work.
Adult ADHD Assessments
ADHD often presents differently in adulthood, with symptoms such as distractibility, time blindness, impulsive decision-making, and difficulty prioritizing tasks. Many adults are diagnosed later in life after years of struggling with organization, work performance, or relationships.
Our adult ADHD assessments in Ottawa and Gatineau help clarify symptoms and provide a path toward targeted support. Testing may include:
-
Review of academic/work history and current functioning
-
Executive functioning assessments
-
Screening for overlapping issues like anxiety or depression
Personalized recommendations for accommodations or therapy
Child and Teen ADHD Assessments
For children and adolescents, ADHD testing can help families and educators better understand the child’s learning profile and behaviour. Early identification allows for timely support at home and school.
Child ADHD assessments typically include:
-
Parent and teacher input through questionnaires
-
Age-appropriate cognitive and behavioural testing
-
Evaluation of emotional regulation and attention skills
