What would prompt such a caption?!? And why would any rational person choose Wikipedia as a source for timely tips on how to approach and deal with their Parkinson's? Wikipedia is the last place to go for timely information about a disease as complex and ever-changing as PD (unless of course, like RP, you have a penchant for gloom and doom). A glimpse at the numerous outdated 'references' should provide some clues as to the relevance of the text to the here and now.
In these last few years alone (since the bulk of the aforementioned 'referenced' dire conclusions were drawn) numerous promising breakthroughs have been made on numerous fronts by numerous institutions in amazing new fields like nanotechnology:
Researchers are currently working to genetically modify blood cells to produce and deliver GDNF throughout the damaged brain. The belief is that these blood cells (macrophages) will then “teach” neurons to make the GDNF protein for themselves as needed.
Focused Ultrasound: Scientists have just recently developed a non-invasive means by which to penetrate the blood-brain barrier creating a new, more efficient way to deliver drugs, chemicals, stem cells, and/or therapies using focused ultrasound and 'microbubbles'.
Other institutions and universities are exploring the use of variously engineered antibodies to target misfolding alpha-synuclein proteins and tau oligomer aggregates - to be either implanted or delivered intravenously (or with microbubbles?) - while still others are experimenting with the use of 'inactivated viral vectors' as specialized delivery vehicles for gene transfer.
Then, of course, there is the plethora of global biotech firms hustling to be the first with the latest induced pluripotent stem cell (IPSC) breakthrough - Parkinson's turn is coming up.
In other words, don't roll over and kick your legs up yet...
