In the world of Parkinson’s research, a great deal of new research and news was reported:

In August 2024, there were 1,088 research articles added to the Pubmed website with the tag word “Parkinson’s” attached (7,928 for all of 2024 so far). In addition, there was a wave to news reports regarding various other bits of Parkinson’s research activity (clinical trials, etc).

The top 5 pieces of Parkinson’s news
