Noradrenaline (Norepinephrine) and ADHD

Professor Trevor Robbins discusses whether ADHD is a disorder of the noradrenaline system.

ADHD is a fascinating syndrome that 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 reuptake into neurons. It is still a big puzzle how methylphenidate works; is it the noradrenergic effect or the dopaminergic effect? We don’t know. It may be both.
