Which neurotransmitter changes are most associated with ADHD?

Explanation:
ADHD is tied to reduced dopamine and norepinephrine signaling in the brain’s prefrontal circuits that govern attention and executive function. When these catecholamines are lower, sustaining attention, planning, and impulse control become more difficult. Medications that increase dopamine and norepinephrine in these pathways often lead to symptom improvement, which reinforces why a decreased baseline of these transmitters is the characteristic pattern. Serotonin changes and GABA alterations are not the primary features of ADHD, making them less central to the typical neurochemical profile.
