Dietary and nutraceutical-based therapeutic approaches to combat the pathogenesis of Huntington's disease

Among several neurodegenerative diseases, Huntington disease has posed a major threat across the world, particularly in the aged population. The disease is caused due to expansion of cytosine-adenine-guanine repeats which further triggers the formation of a mutant huntingtin protein responsible for neuronal death. Numerous pathophysiologic mechanisms have been implicated in Huntington's disease. Striatum and cortex represent the most affected parts of the brain. Even though a wide range of medicines are available but they possess serious side effects. Therefore, the emergence of nutraceuticals derived from natural sources has received great attention in the pharmaceutical domain. Nutraceuticals are health-promoting supplements and enhance immunity in human beings. Currently, oxidative stress is the leading factor for chronic diseases that occur due to low intake of antioxidants. Herbal nutraceuticals are said to be enriched with a massive number of antioxidants. Therefore, this article throws light on various herbal nutraceuticals and their noteworthy effects on Huntington's disease.
