A comprehensive review and recent advancement in the application of tannins for treating Parkinson disease

Abstract

Introduction: Parkinson's disease (PD) is a neurodegenerative disorder characterized by progressive loss of dopaminergic neurons in the substantia nigra. Despite extensive research, the etiology of PD remains elusive, and current treatments focus primarily on symptomatic relief rather than disease modification. Methods: The papers were searched in Web of Science, Scopus, PubMed, PubMed Prime, Cochrane library, Sciencedirect and Google Scholar as web resources. This article includes information about tannins research and reviews in the treatment of PD. However, other paper related to CNS have been avoided. Results: In recent years, there has been growing interest in exploring the therapeutic potential of natural compounds, such as tannins, for the management of PD. Tannins, polyphenolic compounds found abundantly in various plant species, have demonstrated neuroprotective effects through their antioxidant, anti-inflammatory, and metal chelating properties. This review provides a comprehensive overview of the current understanding of PD pathophysiology, existing treatment modalities, and the potential role of tannins in PD management. Additionally, recent advancements in the application of tannins, including in vitro and in vivo studies, clinical trials, and novel delivery systems, are discussed. Furthermore, challenges and future perspectives regarding the translation of tannin-based therapies into clinical practice are addressed. Discussion: Overall, this review highlights the promising therapeutic potential of tannins in the treatment of Parkinson's disease and underscores the need for further research to elucidate their mechanisms of action and optimize their clinical efficacy.
