The Roots of Borderline Personality Disorder - Neuroendocrinology & Neurochemistry

In this episode, we explore how neuroendocrine systems and brain chemistry contribute to the development of Borderline Personality Disorder (BPD).For the full written version of this material, as well as a YouTube video on this topic, visit my website: https://www.drvalentinradoi.com/resurse-educaionale-1We discuss how serotonin, dopamine, oxytocin, cortisol, and the endogenous opioid system shape emotional regulation and stress responses. Research shows that imbalances in these systems contribute to heightened reactivity, impulsivity, and difficulties with trust and attachment.Through Ana’s story, you’ll hear how everyday experiences - from chronic stress to moments of support - can amplify or soften these biological responses. Her case illustrates why some people may feel emotionally flooded by events that others manage more easily.This conversation highlights a central truth: biology sets the stage, but lived experience writes the play. Neurochemistry and hormones are not fixed fates - in supportive environments, even heightened sensitivity can become a source of vitality, connection, and resilience.
