Biomarkers in the early diagnosis of Parkinson's disease

Qian SUN, Wei CHEN, Sheng-di CHEN

Abstract


Parkinson's disease (PD) is a chronic and progressive neurodegenerative disorder. It has become clear that PD can have a preclinical phase, a period during which neurodegeneration has already begun years before the onset of typical motor symptoms. Consequently, if the early neurodegeneration in PD can be timely diagnosed, it will significantly slow down the progression of the disease and improve the quality of life. To date, there is no fully reliable and validated biomarker for the early diagnosis of PD, but some promising biomarker candidates exist.
