Emotional regulation requires a robust neural connection between the amygdala (which generates raw emotion) and the prefrontal cortex (PFC), which analyzes the emotion and determines the appropriate behavioral response. This process is called 'top-down inhibition.'
In ADHD, the structural connectivity and neurotransmitter transmission (dopamine and norepinephrine) between the PFC and the amygdala are impaired. When a frustrating stimulus occurs, the amygdala fires an intense 'threat/anger' signal. A neurotypical PFC intercepts this signal and down-regulates it. The ADHD PFC fails to intercept it. The raw, unfiltered emotion hijacks the nervous system entirely.
Furthermore, ADHD brains struggle with 'working memory for emotions.' In the middle of an anger spike, the brain literally loses access to previous emotional states (like loving the person you are yelling at) and future consequences (knowing you will regret this). The brain becomes entirely consumed by the overwhelming 'now' of the anger, making self-calming cognitively impossible until the neurochemical storm passes.
