This picture is the brain with decreased Dopamine function. Imagine the red dots as the neurotransmitter Dopamine. There are few of them and they are moving sluggishly. This represents slow “Dopaminergic” neurotransmission that leads to a poor utilization of the brain, resulting in AD/HD symptoms.
We will now look at the brain after supplementing with missing Dopamine, as a result of the use of stimulant medications.
