As a multi-factorial degenerative disease,Parkinson’s disease(PD) leads to tremor, gait rigidity,and hypokinesia, thus hampering normal living. As this disease is usually detected in the later stages when neurons have degenerated completely, cure is on hold, ultimately leading to death due to the lack of early diagnostic techniques. Thus, biomarkers are required to detect the disease in the early stages when prevention is possible.Various biomarkers providing early diagnosis of the disease include those of imaging, cerebrospinal fluid,oxidative stress, neuroprotection, and inflammation. Also,biomarkers, alone or in combination, are used in the diagnosis and evolution of PD. This review encompasses various biomarkers available for PD and discusses recent advances in their development.
