Is an adult ADHD assessment different from a child ADHD assessment in Ontario?

Yes. An adult ADHD assessment in Ontario is organized differently from a child assessment, even though both ask about attention, hyperactivity, and impairment. Child assessments usually rely on parent and teacher histories, developmental milestones, and school information, and they are often done by paediatricians or family doctors under OHIP when medically necessary, sometimes with child and adolescent psychiatry. Adult assessments put more weight on childhood history gathered retrospectively, current work or post-secondary impairment, and ruling out other adult conditions. Public adult psychiatry access is limited, and private psychologist or psychoeducational testing is not listed as an OHIP insured physician service.
