If you believe you have experienced an ADHD misdiagnosis, it is okay to question the outcome and seek further clarification. Diagnosing ADHD can be complex, especially when symptoms overlap with other conditions or are masked by coping strategies. Trusting your own experience is important, and you are entitled to challenge a result that does not feel accurate. 

In cases of ADHD misdiagnosis, the next step may be to request a second opinion ADHD from another clinician. You can ask your GP for a referral to a different service or specialist. Be prepared to explain why you disagree, share specific examples, and bring any relevant documents or feedback that supports your concerns. 

A disputed diagnosis ADHD does not mean the process is over. It means more information may be needed to get things right. Staying calm, clear, and persistent gives you the best chance of being heard and understood.
