Can Dopamine and Norepinephrine Deficits Explain Emotional Dysregulation in ADHD? 

Yes, growing research suggests that dopamine and norepinephrine deficits play a significant role in the emotional dysregulation often seen in ADHD. While emotional symptoms like mood swings, irritability, and difficulty managing frustration are not always part of formal diagnostic criteria, they are common and distressing aspects of the condition, and they are deeply rooted in neurochemistry. 

Dopamine and Affect Regulation 

Dopamine helps modulate the brain’s response to both rewards and stress. It supports affect regulation by balancing emotional responses and helping individuals assess situations before reacting. In ADHD, low dopamine activity in the prefrontal cortex and limbic system weakens this internal control system. This often results in quick emotional shifts, overreactions, and difficulty returning to a calm baseline after being upset, classic signs of emotional dysregulation. 

Norepinephrine and Mood Stability 

Norepinephrine regulates arousal, alertness, and emotional readiness. When norepinephrine signalling is impaired, it can cause emotional overreactivity or emotional fatigue. This contributes to irritability, low frustration tolerance, and rapid mood changes. In ADHD, individuals may feel constantly overstimulated or, conversely, under-aroused, both of which make emotional self-regulation harder to manage. 

Together, dopamine and norepinephrine deficits reduce the brain’s ability to filter emotional responses and regulate mood, making emotional ups and downs in ADHD more intense and harder to control.
