Can ADHD be misdiagnosed?

Yes, ADHD can be misdiagnosed, especially if the assessment is not thorough or if the symptoms mimic those of other conditions.

For example, anxiety, trauma, autism, or sensory processing issues can all present with inattention, restlessness, or emotional dysregulation. Some people may receive an ADHD diagnosis when the underlying issue is actually something else—or vice versa.

That’s why a comprehensive assessment by a qualified psychologist or psychiatrist is critical. It should include a full developmental history, behavioural rating scales, and input from multiple settings (home, school, work).
