Ultra-sensitive techniques for detecting neurological biomarkers: Prospects for early diagnosis.

Identifying reliable biomarkers and ultra-sensitive techniques are crucial for the early detection of neurodegenerative disorders (NDDs) to improve the clinical diagnosis and development of effective disease-modifying treatments. Here, we discussed recent technological advancements that enabled scientists to monitor brain health by detecting biological molecules even at lower levels. These technologies enabled the detection of neurological biomarkers in blood, revolutionizing the diagnosis and prognosis of NDDs. Moreover, it provided a better understanding of disease pathology's long-term effects, resulting in fewer invasive tests, early diagnosis, faster drug development, and possibly more effective therapies as possible outcomes.
