Why Some Children Become Violent & have PDA: The Missing Link Parents Need to Know (Pyrol Explained) with Vicky Finlayson

from The Brain Development Podcast · host Lara Barnes

If you’ve ever found yourself asking, "Why is my child so aggressive?" or felt the heartbreak of a violent outburst you can't explain, this episode is for you. We sit down with Vicky Finlayson to discuss Pyrole Disorder—a frequently overlooked biochemical imbalance that strips the body of the very nutrients needed for calm: B6 and Zinc. When these "scaffolding" nutrients are depleted, children are left with a critically low tolerance for stress, leading to rages that aren't a choice, but a biological crisis. We dive into the groundbreaking research of the Walsh Institute, explore why common supplements like Omega-3 can sometimes backfire, and discuss a simple, non-invasive test that can provide life-changing answers in as little as two weeks. It’s time to move past the labels of "oppositional" and look at the internal stress driving the behavior, offering a pathway toward true regulation and peace for the whole family. Key Takeaways Pyrole Disorder causes the body to "pee out" vital B6 and zinc, which are essential cofactors for the calming neurotransmitters GABA and Serotonin. Aggressive outbursts and poor stress tolerance in neurodiverse children are often physiological coping mechanisms, not deliberate behavioral choices. Internal stressors, such as chronic bacterial or viral infections, can drive up pyrole production just as much as environmental stress. While usually considered healthy, Omega-3 supplements can devastate children with high pyroles by further unbalancing the Omega-6/Omega-3 ratio. Pyrole Disorder is linked to irrational fears, phobias, and severe blood glucose issues due to its impact on the insulin pathway. 00:00 – Introduction 00:32 – The Stigma of Violence in Neurodiversity 01:03 – Dr. Walsh’s Research on Violent Offenders 02:37 – Stress and Pyrole Production 03:52 – The Role of GABA and Serotonin 05:27 – The Link Between Copper and Violence 09:41 – Testing for Pyrole Disorder 10:48 – Case Study: Overcoming Severe PDA 12:54 – The Personal Impact of Phobias 15:05 – Biology Over Behavioural Choice 16:00 – Closing and Contact Information Vicky Finlayson Links ⁠⁠⁠https://thehappyhealthyunicorn.com/⁠⁠⁠ ⁠⁠⁠https://www.instagram.com/thehappyhealthyunicorn⁠⁠⁠ SOCIAL/IMPORTANT LINKS ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.tiktok.com/@braindevelopmentuk⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.instagram.com/braindevelopmentuk/⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.linkedin.com/in/larakelly/⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https:/www.braindevelopment.co.uk⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ HOST BIO Lara Barnes a successful woman in tech found herself managing behavioural, learning and speech difficulties with her son, she learn functional neurology and how to change the brain to correct his symptoms and build his left brain.
