Old age is the only proven factor in the development of PD. It is thought that oxidative stress which is more triggered in old age plays a vital role in the formation of dopaminergic neurotoxicity. In this review, the relationship between oxidative stress and PD will be examined. Material and Method: The databases in the health sciences field were used to compile the studies conducted to determine the relationship between PH and oxidative stress. Previously published articles such as Web of Science have been used. Result and Discussion: Parkinson's is a neurodegenerative disease resulting from the complex interaction of genetic and environmental factors that affect on many basic cellular process. Oxidative stress threatens genetic integrity and contributes to the development of PH. Avoiding damage products due to oxidative stress and drawing a protective treatment protocol may be a crucial strategy for maintaining healthy brain function and protecting the organism from neurodegenerative diseases such as Parkinson's disease.
