Abstract

Parkinson's disease (PD) is the most common movement neurodegenerative disorder. Although our understanding of the underlying mechanisms of pathogenesis in PD has greatly expanded, this knowledge thus far has failed to translate into disease-modifying therapies. Therefore, it is of the utmost urgency to interrogate further the multifactorial etiology of PD. DNA repair defects cause many neurodegenerative diseases. An exciting new PD research avenue is the role that DNA damage and repair may play in neuronal death. The goal of this mini-review was to discuss the evidence for the types of DNA damage that accumulates in PD, which has provided clues for which DNA repair pathways, such as DNA double-strand break repair, are dysfunctional. We further highlight compelling data for activation of the DNA damage response in familial and idiopathic PD. The significance of DNA damage and repair is emerging in the PD field and linking these insights to PD pathogenesis may provide new insights into PD pathophysiology and consequently lead to new therapies.
