Recently, there is increasing evidence that oxidative stress has an important role in neurodegenerative diseases. Oxidative stress and its effects cause damage to critical brain regions; thus, it is thought to occur with the disruption in the mechanisms regulating neuronal signal communication. Clinical studies have found significant changes in antioxidant enzyme, lipid peroxidation, and nitric oxide levels in patients suffering from various neurodegenerative diseases. In the mitochondrial complex, reactive oxygen radicals are formed by the escape of some electrons from the chain during electron flow and mitochondrial dysfunction develops with electron transport chain inhibition. Mitochondrial dysfunction and oxidative damage may cause permanent adverse effects in the nervous system by creating changes in the intracellular signaling system, intracellular calcium balance and DNA structure. In this article, the current information is reviewed and the relationship of neurodegenerative diseases with oxidative balance is analyzed through clinical, animal and cell culture studies.
