Lesson Reach Founder
This lesson explores two major neurodevelopmental disorders — ADHD and Autism Spectrum Disorder (ASD) — through the lens of biology, genetics, and real-world outcomes. Using the case of a child named Diego, longitudinal research, and a close look at debunked myths, the video unpacks what actually happens in the brain and what that means across a lifetime. You'll walk away with a clearer, science-grounded understanding of conditions that affect millions of children and adults worldwide. In this video: • How ADHD is defined by two clinical pillars — inattention and hyperactivity/impulsivity — and why the threshold is interference with normal functioning • Longitudinal outcomes for untreated ADHD: the Klein et al. (2012) study linking childhood ADHD to lower education, unemployment, substance abuse, and higher divorce rates • The neurobiology of ADHD: dopamine deficits in the frontal lobe, structural brain differences, and why stimulant medications work • Four explanations for rising ADHD diagnosis rates, including overdiagnosis, greater awareness, shifting DSM criteria, and attention-fracturing technology • Leo Kanner's 1943 discovery of early infantile autism and the three core disturbances of ASD: social interaction deficits, communication deficits, and repetitive behaviors • Why Asperger's disorder was folded into the Autism Spectrum in the DSM-5, and the real-world impact that reclassification had on families • The fraudulent MMR vaccine study, the DeStefano et al. (2013) immunogen data that disproved any link to autism, and the psychology of why the myth persists #OpenStax #Psychology #ADHD #AutismSpectrumDisorder #Neurodevelopment OpenStax Content adapted from "OpenStax Psychology 2e", by OpenStax licensed under CC BY 4.0.
