Taking responsibility gives you control over your future. Learn how owning your decisions, habits, mistakes, and actions can strengthen confidence, improve relationships, and create meaningful…
Well, to understand that outward emotional explosion over a hot car, we really have to look at the brain's internal routing system.
The foundational premise here is that ADHD is a neurological difference in how the brain pursues stimulation.
Not a behavioral disorder.
Right.
Exactly.
Not a behavioral disorder.
So in a neurotypical brain, the prefrontal cortex acts as the executive command center.
It handles working memory, your perception of time, logical problem solving.
Dr. Rozier actually compares this area to a whiteboard.
Okay.
A whiteboard.
Yeah.
So in a standard brain, you write a task on the board and it just stays there while you execute it.
But the sources indicate that for the unmedicated ADHD brain, that whiteboard doesn't just get crowded, right? It essentially erases itself constantly.
I'm trying to visualize the biological mechanism here.
Why won't the ink stay on the board?
That comes down to neurotransmitters, specifically dopamine.
Ah, dopamine, right.
Dopamine is essentially the ink for that whiteboard.
It's the chemical that allows the prefrontal cortex to hold on to a thought, evaluate it, and actually initiate action.
Okay.
It doesn't produce or process dopamine efficiently.
So the prefrontal cortex tries to write on the whiteboard, but the marker is just completely dry.
Oh, wow.
