Can a Child Be Misdiagnosed with ADHD When They Actually Have RAD? 

Yes, it is possible that ADHD can be misdiagnosed as RAD. Both conditions share similar symptoms like impulsivity, emotional dysregulation, and attention difficulties, which can sometimes lead to diagnostic errors. However, the underlying causes of these behaviours are quite different, and identifying the true condition is crucial for effective treatment. 

ADHD Misdiagnosis as RAD 

Children with RAD may display behaviours that overlap with ADHD symptoms, such as inattention, hyperactivity, and impulsive actions. ADHD is primarily a neurodevelopmental disorder linked to attention regulation and impulsivity. In RAD, emotional reactions are often driven by fear of abandonment or difficulties in forming emotional bonds, whereas ADHD involves a chronic struggle with focus and impulse control, without the same emotional triggers. 

Why Misdiagnosis Happens 

Mental health misdiagnosis can occur when clinicians focus mainly on external behaviours like aggression or impulsivity, which are common to both disorders. RAD’s core issue lies in attachment and relational difficulties, which may not always be apparent without a detailed family history or trauma background. Without considering these emotional factors, a child could be incorrectly diagnosed with ADHD. 

ADHD misdiagnosis as RAD in children with RAD highlights the importance of considering attachment history and emotional regulation issues to ensure the right treatment. Proper diagnosis leads to more effective interventions and better outcomes.
