ATM and Parkinson disease: In the present review, we summarized the clinical presentations and biology backgrounds of NDs, including Parkinson’s disease (PD), Huntington’s disease (HD), and Alzheimer’s disease (AD) and explored the role of molecular mechanisms, including dys-regulation of epigenetic control mechanisms, Ataxia-telangiectasia-mutated protein kinase (ATM), and neuroinflammation in the pathogenesis of NDs.
