<p>Neurodegenerative disease represents a significant public health concern, with conditions, such as Alzheimer's disease and Parkinson's disease, being among the most prevalent. The primary risk factor for these neurodegenerative diseases is the process of aging. Key factors, such as oxidative stress and mitochondrial dysfunction, play a crucial role in initiating neurodegeneration. The progressive deterioration and neuronal loss in both the central and peripheral nervous systems are hallmark features of neurodegenerative diseases. Plant-derived natural products and their bioactive components, such as curcumin, resveratrol, genistein, marine algae, quercetin, apigenin, and luteolin, have shown promise as therapeutic agents for treating neurodegenerative diseases. There are various medications approved for the management of neurodegenerative diseases; their usage is primarily limited to providing symptomatic relief. The utilization of natural products holds significant promise for the prevention and treatment of neurodegenerative diseases (ND). The review provides evidence that natural products and their bioactive compounds could be beneficial in the treatment of neurodegenerative disorders. This article delineates the Keap1-Nrf2-ARE pathway’s role in ND progression, shedding light on the therapeutic efficacy of natural products and their bioactive constituents that have demonstrated neuroprotective properties.</p>
