What Brain Structure and Function Abnormalities Are Shared Between ADHD and Autism? 

PostedAugust 19, 2025
UpdatedSeptember 4, 2025
ByMy Patient Advice

Both ADHD and autism share several brain structure and function abnormalities, which contribute to the common cognitive and behavioural challenges seen in both conditions. Brain structure ADHD research and studies on autism have shown that differences in key brain regions, particularly the prefrontal cortex, are commonly found in both groups. The prefrontal cortex, which is involved in executive function such as decision-making, impulse control, and emotional regulation, is often underactive in individuals with ADHD and autism. 

Additionally, ADHD causes such as deficits in attention and self-regulation are frequently observed in both conditions. Brain scans ADHD and imaging studies of individuals with autism reveal abnormalities in areas like the basal ganglia, which are responsible for controlling movement and regulating behaviour. These differences in brain function may help explain why individuals with both ADHD and autism often struggle with organisation, social interactions, and emotional responses.

Better Behaviour Management

Treatments can support both ADHD and autism patients by helping them manage attention, focus, and social interactions. 

Focusing on the similarities in brain function between ADHD and autism can aid in tailoring interventions to improve cognitive and behavioural outcomes for individuals with either condition.
