Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that ADHD is primarily caused by frontostriatal dopamine dysregulation affecting executive function?

Yes. Current neurobiological and pharmacological evidence supports the view that frontostriatal dopamine dysregulation and associated alterations in prefrontal-subcortical circuits contribute significantly to executive dysfunction in ADHD.

Verdict: SUPPORTED · 4 sources for, 0 against · Last checked

The analysis

The retrieved papers consistently highlight the foundational role of dopaminergic neurotransmission and frontostriatal or prefrontal network abnormalities in the pathophysiology and executive dysfunction of ADHD, aligning well with the claim.
