Neurodegenerative Diseases and Aging: Investigating New Biomarkers for Early Diagnosis and Treatment

Abstract

Neurodegenerative diseases (NDs) such as Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS) pose significant challenges to public health, particularly with an aging global population. Early diagnosis and intervention are critical to slowing disease progression and improving quality of life. Biomarkers have emerged as crucial tools for detecting these diseases in their earliest stages, offering a potential pathway to developing more effective treatments. This paper reviews current research on the role of biomarkers in the diagnosis and treatment of neurodegenerative diseases, with a focus on the potential of new biomarkers for improving early detection. Additionally, the paper examines the biological mechanisms underlying NDs and discusses the challenges and future directions in biomarker discovery.
