Classification and Staging in Parkinson’s disease

Introduction: PD classification & staging
From the MDS Leadership

In this edition of Moving Along, we can read four excellent and thought-provoking articles from colleagues on the topic of the biological definition and staging of Parkinson’s. If ever a topic was “hot” then this one is “white hot” in our field just now.

Read complete introduction 

Sitting behind all of the articles is a common wish to achieve an earlier diagnosis for people with Parkinson’s and related disorders, perhaps even before symptoms have appeared. The ultimate aim is the ability to identify people destined to develop or in the earliest stages of Parkinson’s for clinical trials of disease-modifying precision therapies, in order to find the holy grail of a treatment to slow or arrest disease progression. Achieving a better understanding of the pathobiology of these disorders underpins such an aspiration. 

The approaches outlined in the two Lancet Neurology papers have much in common, but also (as highlighted by Professors Sampaio, Cardoso and Trenkwalder) differ in important ways. We may certainly conclude that the widespread adoption of tests such as the alpha-synuclein seed amplification assay is premature and that such approaches are “developmental” at present, pending further data. These papers have stimulated a rich ongoing discussion and highlight the enormous potential gains that might be made, if a robust biologically based classification system can be devised.    

Irrespective of any differences, we applaud the collective endeavours to progress the diagnosis and management of people worldwide with Parkinson’s and related disorders.    

The International Parkinson and Movement Disorder Society (MDS) stands ready to convene with stakeholders and to seek to harmonize approaches for future patient benefit. We wish to reassure our membership and readers that the MDS is actively considering this fundamental shift in thinking in our field, and given our global representation, recognises the need and responsibility to contribute to leadership in this effort.

Moving forwards from Moving Along, watchfor a formal MDS scientific statement and commentary on the biologically based proposals that is being prepared for submission for publication.
