I'm 64, diagnosed with PD 18 months ago but have had symptoms of no left arm swing, rigidity of torso, leaning forwards when walking, and bradykinesia for some years before that, no tremor. I was initially started on Madopar with no positive response, just bad reactions and I felt so sick I couldn't even work. Tried Sinemet instead in case it made a difference but again once I got up to a certain level I felt very ill so went off that too. I chose then not to medicate and had a year of sleeplessness and depression as I was coming to terms with my new reality but that is thankfully behind me now and I'm feeling more positive and happy.
Currently I'm on a Mao B inhibitor (Selegiline) and small dose of Nortriptyline, both of which could have helped a bit with the depression, whatever, it's so good not to feel bad I'm sticking with it.
The reason I write is that I have just finished a four week session of LSVT Big and finally have something that has actually helped improve my life and given me hope that I have taken charge of changes. It's one on one with a trained physio, four sessions a week for four weeks but as far as I'm concerned it was the best money invested in myself ever. Basically she helped my brain re-remember that I have a left arm at all, I can now swing it in time with my walking and my walking stance is much more upright and decent stride length again. She also concentrated on tasks I had found difficult like doing up buttons, dealing with change, unscrewing bottles etc, now I do them all with BIG movements, much better.
I'd highly recommend this program to anyone, particularly at an early stage of PD. As an orchardist I need my fine motor skills and I think she's given me another summer of pruning, each one counts!
