RSD UNDERSTAND
The opening section of Heather Lowry’s ADHD Rejection Sensitivity Toolkit introduces Rejection Sensitivity Dysphoria (RSD) as a distinct, intense emotional and physiological reaction that goes beyond ordinary sensitivity. It explains that for people with ADHD, even minor criticism or perceived disapproval triggers a rapid, high‑threat response because of neurobiological differences: heightened amygdala reactivity, reduced prefrontal cortical “braking” capacity, and a chronically low baseline of dopamine. The text describes how the brain interprets rejection as a danger signal, flooding the body with stress hormones, activating the limbic system, and temporarily disabling rational, calming processes in the prefrontal cortex. This cascade creates the overwhelming, “all‑consuming” experience of RSD, framing it as a survival‑type response rather than a character flaw.

Defining Rejection Sensitivity Dysphoria (RSD) for ADHD
A clear, empathetic definition of RSD that distinguishes it from ordinary sensitivity and frames it as a powerful emotional‑physical reaction specific to ADHD brains.
Amygdala Hyperreactivity: The Brain’s Alarm System in RSD
Explanation of how the amygdala’s heightened threat detection floods the body with stress hormones when rejection is perceived, initiating the RSD cascade.
Prefrontal Cortex Regulation and Dopamine Deficits in ADHD‑Related RSD
Discussion of reduced prefrontal “braking” power and low baseline dopamine, showing why rational thought and emotional calming are compromised during RSD episodes.
