As I read posts here i see we mostly concentrate on alleviating the physical symptoms and not much on the cognitive side. Both are of very great importance
You can probably manage to accept an accelerated decline in cognitive ability if you have PD in your 70s, or 80s and have accomplished some few things in life, but if you are in your 40s or 50s it is devastating and crushing particularly when the neurologists tell you "there is nothing you can do about it (apart from slowing it down a little bit)"
I'm in my early 50s and being a very late starter in life, I have many many things still to accomplish and need a lot of physical energy and high steady cognitive ability to push through. I can't think on my feet at public meetings anymore. My attempts to use my brain on the fly - I begin to tremor massively. Not only are my tremor symptoms destroying my ambitions, managing the disease on the whole is overwhelming
These days I can't even have formal meetings with colleagues and business partners without my tremors distracting and eventually destroying any good outcomes to the meetings
I shouldn't have to avoid formal meetings, I need to be able to deal with it, but I can't. I'm fighting a loosing battle.
This is a sign significant decline in cognitive ability and it depresses me
I am encourage though by some few people here whose technical posts indicates strong cognitive ability. People such as iqbaliqbal Kia17 and easilly .But when you enquire further you reallise they don't have tremor dominant PD, I think tremor dominant PD decreases cognitive ability faster than rigidity dominant PD
