    1. In other patients, scans revealed damage to the nervous systems of the intestines and heart before the damage in the brain's dopamine system was visible

      Questions:

      • What kind of damage to the nervous systems of the intestines and heart were seen?
      • Did the damage to the nervous systems of the heart and intestines occur simultaneously, or were there any instances in which damage was revealed in one organ before the other?
      • Is it possible that the damage began in the intestine first, then went to to the heart, and then went to the brain?
