parkinson's disease (pd) is a progressive degenerative disease of the basal ganglia, characterized by the loss of dopaminergic cells of the substantia nigra, pars compacta (snc). surgical ablation has been used to treat parkinson's disease. in the 1990s, the pallidum was a common surgical target. unilateral pallidotomy improves tremor and dyskinesia on one side of the body (opposite the side of the brain surgery), but bilateral pallidotomy was found to cause irreversible deterioration in speech and cognition.









































two other rapidly evolving or potential surgical approaches to parkinson's disease are deep brain stimulation (dbs) and restorative therapies.

oxidative stress and lipid peroxidation are believed to be contributing factors leading to neuronal loss and mitochondrial dysfunction in the substantia nigra in parkinson's disease, and may play an early role in the pathogenesis of alzheimer's disease. it is reported that cl content in the brain decreases with aging, and a recent study on rat brain shows it results from lipid peroxidation in mitochondria exposed to free radical stress. another study shows that the cl biosynthesis pathway may be selectively impaired, causing 20% reduction and composition change of the cl content. it's also associated with a 15% reduction in linked complex i/iii activity of the electron transport chain, which is thought to be a critical factor in the development of parkinson's disease.
