Parkinsons is not terminal, you die with it, not FROM it, despite what you read in the press about someone who has died from it! It's nonsense.
OH was diagnosed 16 years ago, aged 47, and still not bed bound, not wheelchair bound, has good and bad days. Good day, walks to town and does jobs around the house, bad days, immobile at various times during the day when meds wear off or they have been taken late.
A recent setback with a dislocated shoulder, but, after having the reablement team of carers in for the last 8 weeks, pretty much back to where they were before the shoulder problem. Hopefully a week today we are off on a cruise.
It's a case of getting the meds right, and on time. OH takes meds every two and a half hours, yes it's a pain, especially when out an about, but worth it to be as OK as you can.
