Thanks for that. Let me just quickly ask you this, does whatever medication you have used for this issue seem to have helped you? Apparently in reading about this, some patients get better for awhile and then worsen with treatment, especially with the dopamine agonist approach (I guess they call this 'augmentation'). So, some people on some of these boards and sites and in some of the actual medical literature recommend caution about treating PMLD. It just seems that not a lot is known about this disorder. Thanks again for replying. I do appreciate it.
