Neurodegenerative diseases (NDDs) comprise a large number of disorders that affect the structure and functions of the nervous system. The major cause of various neurodegenerative diseases includes protein aggregation, oxidative stress and inflammation. Over the last decade, there has been a gradual inclination of neurological research in order to find drugs that can prevent, slow down, or treat these diseases. The most common NDDs are Alzheimer's, Parkinson's, and Huntington's illnesses which claims the lives of 6.8 million people worldwide each year and it is expected to rise by 7.1%. The focus on alternative medicine, particularly plant-based products, has grown significantly in recent years. Plants are considered a good source of biologically active molecules and hence phytochemical screening of plants will pave the way for discovering new drugs. Neurodegeneration has long been linked to oxidative stress, either as a direct cause or as a side effect of other variables. Therefore, it has been proposed that the use of antioxidants to combat cellular oxidative stress within the nervous system may be a viable therapeutic strategy for neurological illnesses. In order to prevent and treat NDDs, this review article covers the therapeutic compounds/ metabolites from plants with the neuroprotective role. However, these exhibit other beneficial molecular functions in addition to antioxidant activity is the potential application in the management or prevention of neurodegenerative disorders. Further, it gives future researchers the significance of considering peptide-based therapeutics through various mechanisms in delaying or curing neurodegenerative diseases.
