Concerned RN,
Your Mother is lucky to have your support ...especially one with an RN background. Here are my observations/comments from two perspectives.
I was diagnosed with PD in 2001. I have been VERY fortunate that my progression has been very slow - still work full-time and do whatever ... with a bit of a shake. I am a very independent person ... and hope to remain so for many years. It's hard when our independence is taken away - harder for some than others. There also becomes a fine line when we may need assistance, but don't want to ask ... or better yet, do need assistance and are willing to ask. It sounds to me like your Mother may fall in the latter category - needs and is willing to ask.
My other perspective comes from my involvement in an exercise program for people of all ages and abilities who have Parkinson's. It's called Rock Steady Boxing -a boxing-based exercise program for people with Parkinson's www.rocksteadyboxing.org What I see in those classes is people who are fighting to maintain their independence. But .... they usually recognize when it's time to ask for or receive a bit of assistance. I think every person with PD gets to a point where they need assistance -whether they like it or not.
I also understand your thought about encouraging independence. It's a fine line. I wouldn't allow your Mom to 'wimp out', but I also would be cognizent of her requests and why ... is it a task/movement she especially struggles with - i.e, and sort of unrelated ... but I and many folks with PD struggle with the cutting motion when cutting meat/food - can't explain it but is common and embarrassing in public. Those of us with PD often move slooooowly. Slow doesn't always work when need to 'spring' out of your automobile seat to a standing position ... it may require a hand to pull oneself up/out.
Lastly, regarding 'wimping out' ... make sure depression isn't a factor. A large percentage of people with Parkinson's suffer from depression - either short-term or long. Depression can certainly rule your life and cause one to not fight or try harder. As a medical professional I'm sure you are aware of that ... but have to mention it.
Again, your Mom is fortunate to have you in your corner (OK, there's the boxing talk ... lol). Best of luck and please post additional questions.
