Was diagnosed with Pernicious Anaemia earlier this year, and doctor asked about my drug regime and whether I knew about B12 deficiency being associated with PD or PD meds!! It only took a little while to uncover a study from University of Athens Greece, as well as an article by PD nutritionist with NPDA that confirmeda connection with long term l-dopa use and PA. This study does not surprise me, though it would seem that PD like PD is little understood, and that many physicians are unaware of some of the ways it can affect patients loves. Both those references were dismissed by my GP as not significant......
