Should ADHD Always Be Diagnosed by a Specialist? 

Yes, but real-world access complicates things. While ADHD diagnosis by a specialist offers the most comprehensive and accurate route, not everyone has immediate access to one. Specialists such as paediatricians, psychiatrists, and clinical psychologists are trained to recognise the subtle differences between ADHD and similar conditions, including anxiety, trauma, learning disorders, and sensory processing issues.  

Why a Specialist Matters 

Specialists bring deeper knowledge of neurodevelopmental conditions, more experience with differential diagnosis, and often use advanced tools like cognitive testing, multi-informant reports, and structured interviews. They are better equipped to assess coexisting conditions, which are common in ADHD but often missed in quick general assessments. 

A GP or school nurse might start the conversation, but only a specialist can deliver a high-confidence diagnosis supported by clinical standards. For complex cases, or when symptoms are mild or masked, that expert evaluation makes a critical difference. 

Paediatrician vs Psychiatrist 

• Paediatricians often lead on ADHD diagnosis in younger children, especially in NHS settings. 

• Psychiatrists, particularly child and adolescent psychiatrists, are trained to assess more complex or comorbid presentations making them essential in teenage and adult cases. 

Conclusion 

While initial concerns can be raised by general practitioners, a specialist diagnosis ensures accuracy, avoids mislabelling, and opens doors to proper treatment and support.
