It's very sad - even for Parkinsons, his is bad. Most cases can have the symptoms reduced quite dramatically with procedures and meds, at least to the level of the interviewer here, but Michael J Fox's seems very pronounced at this stage. To be fair, I think he started developing symptoms quite a bit younger than most. Anything under 50 is considered "early onset"... under 40 is pretty rare and he was only 29 - and that's at official diagnosis, it had probably started with very minor symptoms a year or more before that. Very very unusual.
