Introduction

Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis (ALS), pose significant challenges in modern medicine. These disorders are characterized by progressive neuronal loss, leading to cognitive decline, motor dysfunction, and, ultimately, reduced quality of life. Early diagnosis is crucial for managing symptoms and developing effective therapeutic interventions. Biomarkers have emerged as powerful tools for detecting neurodegenerative diseases at their earliest stages, allowing for timely intervention and improved treatment outcomes. Biomarkers can identify the presence of a disease before noticeable symptoms arise, enabling earlier intervention.[1,2].

Biomarkers are biological indicators found in body fluids, tissues, or imaging results that provide measurable evidence of a disease process. In neurodegenerative disorders, biomarkers serve as crucial diagnostic, prognostic, and therapeutic response indicators. The advancement of biomarker research offers new hope for early detection, precision medicine, and disease-modifying treatments.Neurodegenerative diseases are often diagnosed based on clinical symptoms, which typically appear after significant neuronal damage has occurred. This delay in diagnosis limits the effectiveness of treatments. Biomarkers address this challenge by providing objective, quantifiable measures of disease progression before symptoms become severe. The key benefits of neurodegenerative disease biomarkers. [3,4].

Many neurodegenerative diseases share overlapping symptoms. Biomarkers help distinguish between conditions, ensuring precise diagnosis.Biomarkers allow clinicians to track disease advancement and assess treatment efficacy over time.Pharmaceutical research relies on biomarkers to test the effectiveness of new therapies and tailor treatments to individual patients.Biomarker research has progressed significantly, leading to the identification of various molecular, imaging, and fluid-based indicators for different neurodegenerative disorders.Alzheimer’s disease (AD) is one of the most well-researched neurodegenerative conditions in terms of biomarker development. [5,6].

Elevated levels of amyloid plaques and tau tangles in cerebrospinal fluid (CSF) and brain imaging indicate AD pathology.This protein is released into the blood and CSF following neuronal damage and is a promising marker for AD progression.Positron emission tomography (PET) scans can detect amyloid-beta deposition in the brain, aiding in early diagnosis. Parkinson’s disease (PD) is characterized by the degeneration of dopaminergic neurons. Aggregated alpha-synuclein protein in CSF and blood plasma serves as a key biomarker for PD diagnosis.This imaging technique helps assess dopamine-producing neurons in the brain. [7,8].

Elevated levels of pro-inflammatory cytokines in the blood are associated with PD progression.ALS is a rapidly progressing motor neuron disease with limited diagnostic options. Biomarkers These markers indicate neuronal damage and are detectable in both CSF and blood. Elevated levels of oxidative stress-related molecules have been found in ALS patients.Huntington’s disease (HD) is a genetic disorder caused by mutations in the HTT gene.The presence of abnormal huntingtin protein in blood and CSF is a primary biomarker. Structural brain imaging detects early changes in brain regions affected by HD. [9,10].

Conclusion

Biomarkers represent a paradigm shift in the diagnosis and management of neurodegenerative diseases. By enabling early detection, improving diagnostic accuracy, and facilitating targeted therapies, biomarkers have the potential to revolutionize patient care.
