The 7 Genes Science Linked to ADHD — And What They Do

What if your ADHD brain isn't broken — it's inherited? In this video, Dr. Michael Lenz breaks down 7 specific genes that science has linked to ADHD, and explains why understanding your genetic blueprint changes everything about how you think about your brain.We cover: • DRD4 — Dopamine Receptor D4 (the novelty-seeking gene) • DAT1/SLC6A3 — Solute Carrier Family 6 Member 3 (the dopamine transporter gene) • DRD2 — Dopamine Receptor D2 (the reward system gene) • COMT — Catechol-O-Methyltransferase (the executive function gene) • BDNF — Brain-Derived Neurotrophic Factor (the brain plasticity gene) • SNAP25 — Synaptosomal-Associated Protein 25 (the neural signaling gene) • TPH2 — Tryptophan Hydroxylase 2 (the serotonin connection)These same genes also appear in research on autism, fibromyalgia, and chronic pain — revealing why ADHD and central sensitization often travel together. ADHD is one of the most heritable conditions in all of psychiatry, with a heritability estimate of 70-80%. It's not a character flaw. It's written into your DNA.🔔 Subscribe for more science-backed education on neurodivergence, chronic pain, and the genetics of invisible illness.⚠️ This video is for educational purposes only.
