71. ADHD stimulants do NOT impact the brain's attention networks?!?! with Dr. Nico Dosenbach

Send us Fan MailBench to Bedside: How ADHD Stimulants Really Work—Arousal and Reward, Not Attention NetworksDr. Elise Fallucco launches a new “Bench to Bedside” series and interviews Dr. Nico Dosenbach, senior author of a ground-breaking fMRI study published in CELL  that found that  stimulants do NOT significantly change the brain’s attention networks!?!?! Instead, effects are strongest in arousal (less drowsy, more wide awake) and reward/motivation systems (increasing predicted reward and tolerance of “drudgery”). We discuss:how these findings align with patient experiencewhy ADHD can be a misnomer how video games/TikTok exploit variable reward scheduleshow this changes what we tell patients and families about stimulantsOur conversation highlights implications for destigmatizing ADHD, reframing stimulants as helping wakefulness and motivation rather than “making you smarter,” and how strategies like habit pairing and gamification can make necessary tasks more rewarding.00:00 Welcome to Bench to Bedside Series01:34 What We Thought We Knew about Stimulants03:30 Examining brain networks in ADHD04:03 No Attention Network Effect04:50 Patient reaction to the paper's fundings05:30 Where in the brain are stimulants working?05:45 Arousal Signature06:29 Stimulants also affect the Dopaminergic REWARD and Motivational systems06:41 "More Tolerant of Drudgery"07:18 Stimulants affect Arousal08:08 Stimulants act on Motivation and Reward08:50 Why motivation matters in kids with ADHD09:21 Findings consistent with other human behavioral data and macaque data09:47 Raking Leaves and Hacking the Reward Systems11:24 Clinical Implications of Study11:41 Implications for ADHD Treatment12:58 Did Einstein need stimulants?13:16 Hyperfocus and Real Life Examples: Deer Hunting15:24 Reward Hacking : Video Games and TikTok16:42 Non Prescription Tricks to Hack the Reward System18:15 Procrastination in ADHD and dopamine19:01 Different ADHD distribution in medicine?19:34 Reframing ADHD20:26 Gamifying Life22:09 Closing Recap - Clinical ImplicationsAbout Our Guest, Dr. Nico Dosenbach:https://dosenbachlab.wustl.edu/For access to the full paper, Stimulant medication affect arousal and reward, not attention networks:https://www.cell.com/cell/fulltext/S0092-8674(25)01373-X Check out our website PsychEd4Peds.com for more resources!Follow us on Instagram @psyched4pedsCheck out our NEW CME Audio-based, on-demand CME Course online at:Pediatric Mental Health CME Toolkit - Cracking the ADHD Code: Essentials for Pediatric Clinicians. https://ce.nemours.org/content/podcast-series-cracking-adhd-code-essential-skills-pediatric-clinicians#group-tabs-node-course-default1
