Parkinson's disease progression is multifaceted: Evidence for the underlying benchmarks

Area of Science:

• Neurology
• Neuroscience
• Movement Disorders

Background:

• Parkinson's disease (PD) is characterized by progressive neurodegeneration.
• Individual PD progression trajectories are highly variable.
• Recognizing progression milestones is essential for clinical management.

Purpose of the Study:

• To highlight the heterogeneous nature of long-term Parkinson's disease progression.
• To emphasize the importance of identifying progression benchmarks and their underlying biological substrates.
• To inform patient expectations and guide PD research planning.

Main Methods:

• This study is a review and conceptual analysis.
• It synthesizes current understanding of PD progression.
• It discusses the implications for clinical practice and research.

Main Results:

• Parkinson's disease progression is not uniform.
• Diverse manifestations and timelines exist for PD.
• Identifying specific progression markers is key.

Conclusions:

• Acknowledging the heterogeneity of Parkinson's disease progression is vital.
• Understanding progression substrates will improve treatments and patient support.
• This knowledge is critical for strategic planning in PD research.
