Biomarkers in Parkinson's Disease.

Area of Science:

• Neurology
• Biomarker Research
• Neurodegenerative Diseases

Background:

• Parkinson's disease (PD) is a significant global cause of disability.
• Effective therapeutics to slow or halt PD progression are urgently needed.
• Reliable biomarkers are essential for optimizing PD diagnosis and treatment strategies.

Purpose of the Study:

• To review recent advancements in Parkinson's disease biomarker development.
• To summarize the current landscape of PD biomarker research.
• To highlight progress across fluid, tissue, and neuroimaging modalities.

Main Methods:

• Comprehensive literature review of recent studies on PD biomarkers.
• Analysis of advances in fluid biomarkers (e.g., blood, CSF).
• Evaluation of progress in tissue and neuroimaging biomarkers for PD.

Main Results:

• Significant progress has been made in identifying and validating PD biomarkers.
• Fluid biomarkers show promise for early detection and monitoring.
• Neuroimaging and tissue biomarkers offer complementary insights into PD pathology.

Conclusions:

• Biomarker development is critical for improving Parkinson's disease diagnosis and treatment.
• Continued research across multiple biomarker types is essential for combating PD.
• The reviewed biomarkers represent key steps toward better management of Parkinson's disease.
