Exploring Diagnostic Markers and Therapeutic Targets in Parkinson’s Disease: A Comprehensive 1H-NMR Metabolomic Analysis – Systematic Review
Abstract
Abstract Parkinson’s disease (PD) affects millions of people globally. Accurate early diagnosis remains a challenge due to the lack of specific biomarkers. This systematic review explores the potential of 1H-NMR metabolomics in identifying diagnostic markers and therapeutic targets for PD. A comprehensive analysis was conducted across databases such as Scopus, Web of Science, PubMed, and Embase, focusing on studies that utilized 1H-NMR spectroscopy to profile metabolites associated with PD progression. The review identifies key metabolites—glutamate, taurine, myo-inositol, glutamine, and creatine—that play critical roles in the pathophysiology of PD. Glutamate, linked to excitotoxicity and neuronal degeneration, emerges as a prominent target for therapeutic intervention, while taurine is associated with oxidative stress. Myo-inositol, a key regulator of autophagy, underscores the biochemical dysregulation associated with PD, similar to glutamine and glutamate. Creatine’s role in neuronal energy metabolism suggests potential avenues for treatment focused on energy supplementation. The reproducibility of metabolite findings varied, indicating the complexity of PD’s metabolomic landscape. Despite challenges in consistency, these metabolites hold promise as biomarkers for diagnosing PD and tracking disease progression. The review underscores the need for further validation of these markers and their integration with other omics technologies to enhance PD management. By…
