Neurodegenerative diseases (NDs) are a diversity of neurological disorders characterized by the progressive degeneration of the structure and function of the central nervous system (CNS). The most common NDs are Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD). Recently, many studies have investigated associations between common NDs with noncoding RNAs (ncRNAs) molecules. ncRNAs are regulatory molecules in the normal functioning of the CNS. Two of the most important ncRNAs are microRNAs (miRNAs) and long noncoding RNAs (lncRNAs). These types of ncRNAs are involved in different biological processes including brain development, maturation, differentiation, neuronal cell specification, neurogenesis, and neurotransmission. Increasing data has demonstrated that miRNAs and lncRNAs have strong correlations with the development of NDs, particularly gene expression. Besides, ncRNAs can be introduced as new biomarkers for diagnosis and prognosis of NDs. Hence, in this review, we summarized the involvement of various miRNAs and lncRNAs in most common NDs followed by a correlation of ncRNAs dysregulation with the AD, PD, and HD.
