Good day folks. My mom has recently been diagnosed with parkinsons. Onset of symptoms was 2 months ago, prior to that she's had issues walking but we assumed it was due to her RA. In 2 months she has gone to not talking and needing to be fed, she's now mostly bed ridden though we drag her to the toilet several times a day, with great difficulty. Has anyone had such extreme speedy onset of symptoms? The neurologist gave us medication and said we should see improvement In a few days, after 2 weeks no improvement and my mom has stopped speaking all together since the meds. Could it be a misdiagnoses
