ADHD is not a disorder of willpower; it is a condition of dysregulation. Decades of neurobiological research demonstrate that altered signaling in key neurotransmitter systems — particularly dopamine, norepinephrine, and serotonin — contribute to the core features of ADHD. These chemical messengers in the brain shape how we focus, prioritize, feel motivated, regulate emotions, and experience reward.

Dopamine is central to motivation, pleasure, reward processing, and goal-directed behavior. When dopamine signaling is adequate, individuals feel calm, satisfied, and capable of sustained engagement. When dopamine tone is reduced or dysregulated, as often observed in ADHD, the brain compensates by seeking novelty, urgency, or high stimulation. This contributes to distractibility, procrastination on mundane tasks, and the pursuit of immediate rewards over long-term goals.

Norepinephrine supports sustained attention, executive functioning, working memory, and impulse control. In the prefrontal cortex, the brain’s executive control center, dopamine and norepinephrine work together to optimize cognitive performance. When these systems are underactive, individuals may experience task initiation difficulties, emotional reactivity, sensory overwhelm, and mental fatigue.

While not traditionally viewed as a “core” ADHD neurotransmitter, serotonin plays a critical modulatory role in mood, sleep, emotional stability, and behavioral inhibition. Serotonergic imbalance can amplify irritability, anxiety, mood swings, impulsivity, and sleep disturbance, complicating the ADHD clinical picture.

In this engaging and scientifically grounded webinar, you will learn:

• About the neurochemical basis for ADHD and understand what is beneath the surface of symptoms
• How ADHD brains differ structurally and functionally from neurotypical brains, including altered activity in the prefrontal cortex, differences in reward circuitry, variations in cortical maturation and connectivity, and dysregulation within the networks that aid cognitive control
• Gain insight into how these neural systems interact dynamically, and how neurotransmitter balance influences real-world behavior
• How excess hormones and neurotransmitters can lead to over arousal, anxiety, and irritability while insufficient signaling affects executive function, procrastination and motivation
• How serotonin modulates emotional regulation, impulsivity, and sleep stability, with clinical examples to illustrate how neurochemical dysregulation translates to everyday functional difficulties

About evidence-based interventions and how they restore brain function, including:

• Stimulant medications that enhance dopamine and norepinephrine signaling
• Traditional non-stimulant treatments that target norepinephrine
• New and novel nonstimulants that modulate serotonin
• Behavioral interventions that leverage reward systems
• Sleep, exercise, and lifestyle strategies that support neurotransmitter balance
