Biomarkers are disease-specific molecular indicators. In early days,the neurological disease biomarkers were not that accessible; however, the advancements in the technology have enabled the measurement of specific biomarkers for tracking the health of the brain whereas a biomarker is defined as a measurable indicator that is used to identify a particular disease. Additionally, they are used to evaluate the most effective therapeutic regime for specific or drug target identification. In the field of neuroscience, the biomarker plays an essential role in the identification of many neurological disorders and abnormalities.
