• The road ahead: 2020 January 5, 2020 Here at the SoPD, we are primarily interested in disease modification for Parkinson’s. While there is a great deal of interesting research exploring the causes of the condition, novel symptomatic therapies, and other aspects of Parkinson’s, my focus is generally on the science seeking to slow, stop or reverse the condition. At the start of each year, it is a…

It was the first gene to be associated with increased risk of developing Parkinson’s, and the alpha synuclein protein was found to be present in Lewy bodies – a characteristic feature of the Parkinson’s brain. As a result of this association, researcher have used high…
