Neurobiology of Pediatric ADHD & Differential Diagnosis: Prefrontal Dopamine Circuits, Visual Structuring Coaching, and Evidence-Based Home Behavioral Interventions

# Neurobiology of Pediatric ADHD & Differential Diagnosis: Evidence-Based Home Behavioral Interventions

A definitive clinical and neuropsychological guide to pediatric ADHD (Attention Deficit Hyperactivity Disorder). Exploring the biological reality of 2–3 year prefrontal cortex developmental delay, dopamine transporter (DAT) overactivity causing reward deficiency syndrome, differential diagnosis against normal energetic temperament and gifted overexcitabilities, 4-step home visual structuring systems (Time Timer, single-step prompts, token economy), screen-time dopamine detox protocols, and school collaboration frameworks.
