Hello and welcome to the forum.
I am 41 and diagnosed in Feb this year. I have been researching a lot into the disease and how I can counteract it for as long as possible.
Exercise and keeping active is highly recommended so I have been trying to allocate time out of my schedule to do that.
Diet and supplements is what I am experimenting with at the moment, I have cut out sugary snacks and fizzy drinks as that was affecting my sleep and general wellbeing. I am leaning towards a Keto / Mediterranean diet as I generally feel better and have more energy on days that I eat cleaner with no junk food or wheat foods.
PD effects everyone differently, there are various medications available too so it may be a bit of trial and error until your son gets a system that works best for him to keep the symptoms at bay and slow the progression of the disease.
I recently attended the YOPD zoom meeting hosted on this forum and found that to be very helpful discussing my journey and hearing others with theirs. Support is out there for you and your son so please do reach out and ask for help.
What is your sons symptoms, how does it affect him? Has he been given any medication?
Thanks, Rich
