Abstract
Background: The field of medicine and synthetic drug development have advanced rapidly
over the past few decades. However, research on alternative medicine, such as phytochemicals cannot
be ignored. The main reason for prominent curiosity about phytochemicals stems from the belief that
the usage of natural compounds are safer and have lesser detrimental side effects.
Objective: The aim of the present review was to discuss in detail several phytochemicals that have been
studied or are being studied in the context of various neurological disorders, including depression,
Alzheimer’s disease, Huntington’s disease and even neuroinflammatory disorders, such as encephalitis.
Methods: The potential roles of phytochemicals in treating or managing symptoms associated with
neurological disorders have been included in this article. All data included in this paper have been
pooled from various databases, including Google Scholar, PubMed, Science Direct, Springer, and
Wiley Online Library.
Results: Phytochemicals have been widely studied for their therapeutic properties associated with neurological
disorders. Using various experimental techniques for both in vivo and in vitro experiments,
studies have shown that phytochemicals do have antioxidant, anti-inflammatory and neuroprotective
activities, which play major roles in the treatment of neurological diseases.
Conclusion: Even though there has been compelling evidence of the therapeutic role of phytochemicals,
further research is still required to evaluate the safety and efficacy of these medicines. Using previously
published papers as the foundation for additional research, such as preclinical studies and clinical
trials, phytochemicals can become a safer alternative to synthetic drugs for treating a spectrum of
neurological diseases.
Keywords:
