I know there has been discussion of PD and depression but I am afraid that up to now I haven't paid much attention to it. Now I have reason to be concerned because of a family member with PD who is told that she is suffering from depression. Obviously PD and its accompanying problems are a significant reason to become depressed. But here is my question. PD affects brain chemistry-- does PD also chemically cause depression? What drugs are typically prescribed for this type of depression? Prozac? Or other drugs? Thanks. Bryce Jones
