i get the feeling more effort is going to be made on early detection, especially with dna analysis getting cheaper/quicker:

once all the genes are identified that makes one susceptible or more resistant from neurological damage, then drugs can be developed and/or diet, life style modifications, environmental awareness will contribute to avoidance. and who knows, there might be a one time "fix" that would stop the progression.

i think the problem is doctors, mainly general practitioners, not lack of data on early signs. they have no incentive to even train to look for early signs since there is nothing they can do - yet. i played soccer with my GP and he didn't notice the lack of arm swing and after i was diagnosed by a MDS, he had the nerve to tell me he was very skilled at diagnosing pd. and this was a GP in a very large, highly respected healthcare organization that saw a lot of patients.
