Hi, Not sure if I belong here or not! I have a number of medical conditions, symptoms of which seem to overlap with the symptoms of PA. My dad has recently been officially diagnosed with B12 deficiency after a lifetime of Macrocytosis and another close family member is struggling to get her GP to recognise her many symptoms as PA/B12 deficiency. 20 years ago my many neurological symptoms were put down to Parkinsons... however it has not progressed as expected and am now told its 'atypical'. I have a 15 year history of thyroid symptoms which culminated in having a near total thyroidectomy 8 years ago. I take Levothyroxine daily and also I have Vit D deficiency and take co calciferol 800iu. Having read so much about PA I am starting to wonder if I too may be B12 deficient. I will be interested to know if there are any others here who have been wrongly diagnosed with Parkinsons!
