Dopamine

Dopamine is the neurotransmitter with the greatest involvement in ADHD.¹

In ADHD, disorders at all dopamine receptors as well as at the dopamine transporter (DAT) have been documented, although these do not necessarily occur together. ADHD symptoms are also reported as a consequence of encephalitis, which destroys those cells that produce dopamine. As a result, dopamine is not sufficiently present in certain brain areas or is broken down too quickly.

Dopamine is a monoamine, like noradrenaline and adrenaline, whose precursor is dopamine. Dopamine is the most common monoamine in the brain, accounting for 80%.
