eli5: what is the neurobiology of ADHD and how does it lead to behavior/symptoms?
In: 2
The current theory centers on two neurotransmitters: dopamine and norepinephrine. In our brains, dopamine is a kind of motivator chemical, signalling the relative desirability or aversion we have towards a particular outcome. Norepinephrine on the other hand, mobilizes us for action. It’s at its lowest levels when we sleep, and at much higher levels during things like fight-or-flight.
So, in ADHD, the brain is either not producing enough of or not responding to these neurotransmitters. This means that ADHDers can have trouble motivating themselves to do certain tasks or actually initiating action if they are motivated.
