ADHD Tests for Adults

While there is no ADHD test for adults, an ADHD diagnosis can be made by a nurse practitioner, psychologist, family physician, or psychiatrist using assessment tools and conducting a clinical assessment interview. You may want to consider an ADHD diagnosis if:

You suspect you might have ADHD and want to verify it,
You were previously diagnosed with ADHD but need further clarification or confirmation,
You are seeking updated management recommendations for your ADHD,
You require official medical documentation regarding your ADHD diagnosis and recommendations.

What are the types of Assessments in Canada?

An Adult ADHD diagnosis can be made by either a medical assessment or psychological/psychoeducational assessment. These two assessment approaches are different in who facilitates them, the assessment process, and the cost.

Medical Assessment

Individuals’ complete assessment tools and undergo a clinical interview. This evaluation is administered by medical professionals such as physicians, psychiatrists, or nurse practitioners. These medical practitioners can provide a diagnosis as well as recommend and prescribe medication as part of the ADHD management strategies.

Psychological/Psychoeducational Assessments

These evaluations explore cognitive abilities, academic skills, and socio-emotional functioning to diagnose learning difficulties and are conducted by a psychologist. Within this assessment, ADHD may be a component among other assessments. These assessments typically take 1-2 days and can cost thousands of dollars. Psychologists cannot recommend or prescribe medication as part of a management strategy.

It is important that you identify a process that best aligns with your needs and resources.
