I was diagnosed with Parkinson's June 2014 that was changed to Lewy body dementia in 2015 I'm now 59.
The main trouble my oh and I have found is that all the support seems to be aimed at older sufferers Alzheimer's awareness groups help so it's worth looking into what support they can offer in your area,
My oh pushes me to do things all the time she will only help when it's obvious that I can't do something , she keeps me occupied all the time with tasks that stimulate my brain , we practice mindfulness and have found certain meditation music helps particularly the ones aimed at aiding rem sleep,utube is a good place to find these,
starting to go off now but will try and write some more later,
Live well. Cc.
Ps I live in the south of England
