Hi Chris,

The scan can tell how much dopamine your brain is producing. Based on your scan, your brain is not producing enough dopamine, which is unfortunately concerning for Parkinson's disease. The Abilify blocks dopamine and makes your symptoms worse, but it does not cause an abnormal scan. Let's talk about this more at your upcoming appointment and we can go over everything at that time.
