ADHD - Noradrenaline and Dopamine
Professor Trevor Robbins discusses ADHD in relation to noradrenaline and dopamine, both of which are enhanced by ADHD medications such as Ritalin.
ADHD is a fascinating syndrome which is treated effectively by drugs such as Ritalin or methylphenidate and amphetamine, both of which enhance the functioning of dopamine and noradrenaline - methylphenidate by blocking their re-uptake to neurons. It is still a big puzzle how methylphenidate actually works, is it the noradrenergic effect or the dopaminergic effect? We don't know. It may be both.
