There is a huge difference in early on-set Parkinsons (hits at very early age like in thirties ) and old age type.
Mickael J Fox has the early on-set kind . Old age Parkinsons will have you in a wheel chair and likely died in ten years or less.
The later kind moves rapidly and effects speach and body
movement hugely.
I speak from family experience.... I have seen the effects of both types.
Parkinson's in itself leads to a form of depression ... not what
Robin needed for sure
Young on-set Parkinson's gives you 15- 20 more working years (Micheal J Fox )... over 60 (old age type) gives less than half that on average
...the LATER CAN lead to lost speach and
dementia. Only about 10 % of Parkinson's sufferers get the early onset kind ( under 40 )
