The BBC World Service has broadcast a 3 episode programme about PD. While informative, there is nothing (I feel) that is new, but still makes for an interesting listen. Each episode is 26 mins long.
Episode 1 Living with Parkinson's
Presenter Jane Hill’s father and uncle both lived with Parkinson’s. PD, a neurological condition, is increasing globally but how have diagnosis, treatment and attitudes changed?
Episode 2 Exercise
Episode 3 Early Diagnosis & Research
