Abstract

Natural products play a major role in maintaining healthy people and animals and in preventing sickness. Experiments have shown that these natural compounds have several biological properties, including anti-inflammatory, anti-apoptotic, and antioxidant effects. Using Google Scholar, PubMed, and Science Direct database searches, current recorded information was incorporated in this review. The databases listed above were searched using the following Medical Subject Headings (MeSH) terms for data extraction: preventative, natural product, phytoconstituents, natural products for Parkinson's illness, Alzheimer's disease, and natural products for the brain. The effectiveness of natural products in a variety of preclinical models of neurodegenerative diseases has been demonstrated by in vitro and in vivo studies. Phytoconstituents, such as polyphenolic antioxidants, are present in freshwater and marine flora, as well as in fruits, vegetables, nuts, and herbs. These phytoconstituents may help the brain's memory and cognitive processes while preventing neurodegeneration. Moreover, they are essential in the prevention and treatment of various neurodegenerative diseases, including Parkinson's disease, epilepsy, Alzheimer's disease, and other neurological conditions. This review briefly highlights a few neurodegenerative diseases, emphasizing how natural products and nutraceuticals function against neurological disorders.
