hi lurking,
i'm not following research like i used to so this isn't exactly a well informed reply but i'll give it a go.

pd research just isn't getting as much attention as alzheimers and cancer, etc. so you don't see articles summarizing and discussing pd research in general, you have to look for that info on youtube, cut your search criteria down to 1 month or less or on the national pd websites, NPF, FOX, etc.
there's also a lot less posting and discussion on this board which leaves a vacuum.

I also think after the many failures with gene therapy there is less "excitement" about research working on a "cure".

there are many gene therapy trials, the alpha-synclein vaccine trial, there's supposed to be a fetal transplant trial in europe, some stem cell trials.

we'll get some news soon:
Mark your calendars for June 14-18, 2015 and join us for the 19th International Congress of Parkinson's Disease and Movement Disorders
