I've been diagnosed, after years of odd symptoms and six months of mri's, etc. but with RRMS instead of the early stage Parkinson's Disease i believe I have. Be careful what you wish for ... symptoms are similar, but treatments are different. Treatment for RRMS is a self-injection either every night, three or four times a week, once a week intramuscularly, or once a month intravenously done in a clinic. The treatments all have side effects. I have been taking the nightly injections for three years, with no dramatic difference in my ongoing symptoms.
I've now joined a national study group looking at genetic biomarkers for Parkinson's Disease in people who have a family history of PD. I have several members of my parents generation who had PD ... I have no relatives in a very large family who have had MS. I continue the painful nightly injections because I'm afraid to stop without the doctor's okay, and he is convinced that, for the time being, this is MS ... he has not ruled out eventual PD.
My parents had PD, both of them, and neither was disabled until their late seventies and early eighties. MS threatens disability without warning, at an earlier age, unpredictable disability, temporary or permanent unknown. It is a prognosis of lifelong self-injected shots and worry about the unknown ... like a monster under the bed, ready to pounce unannounced.
My goal is to be diagnosed with the PD I know I have ... and then to feel justified in discontinuing the MS med that so troubles me, and beginning the PD medication that might help.
Be careful what you wish for ... and ignore people who suggest that you would be grateful for a diagnosis and "treatment."
