Call for clinician awareness and diagnostic change

In this episode, Ben sits down with Dr Shyamal Mashru, Consultant Psychiatrist and Medical Lead for Adult ADHD, for a clear and compassionate deep dive into Rejection Sensitive Dysphoria (RSD).

Often misunderstood or dismissed as being “too sensitive,” RSD is explored here as a real, neurological experience - one that can hijack rational thought, flood the body with emotional pain, and quietly shape relationships, work, and self-worth. Dr Shyamal explains what RSD is (and isn’t), how it shows up differently across people, and why ADHD brains may be especially vulnerable.

They unpack the science, the role of trauma and hormones, why RSD isn’t currently in the DSM, and what actually helps when rejection hits hard.

If rejection feels overwhelming, confusing, or deeply personal - this conversation offers clarity, relief, and language for what you may have been carrying alone.

To break the cycle, we amplify voices, challenge myths, and keep showing up. Spotlighting stories, stats and hard truths. Smashing stereotypes through honest voices, creative campaigns and research that can’t be ignored.Every month, over 50,000 people turn to The Hidden 20% to feel safe, seen and to learn about brilliant brains.
