If a person takes dopamine increasing medication for some illness, what effect on his/her psych will it have and why?
As I understood, certain area in the brain lacks dopamine, so you have to get it produced somehow. But when medication is taken, it can't affect just certain area, but the whole brain, Is that true?
If that is true, what does excess dopamine do to the brain.
EDIT: mentioned medication is Madopar, used for Parkinson's disease. Also, I edited title ,because I misunderstood it's the dopamine in the medication, not the one that causes dopamine to increase in the brain.
