Traumatic brain injury (TBI) is a serious public health problem, and it is estimated that more than 50 million patients worldwide su ff ered from TBI each year. At present, the diagnosis of TBI mainly relies on scoring scales, and it is extremely necessary to screen objective biomarkers of TBI. A large number of studies have focused on the screening of protein markers of TBI, however, protein markers have short half-life and low sensitivity, so it is important to screen new biomarkers of TBI for its rapid diagnostic and treatment. As a lack of effective therapeatic drugs, TBI was mainly treated according to symptoms. microRNAs (miRNAs) are a class of small non-coding RNAs whose altered expression levels are associated with a variety of diseases in central nervous system including TBI and play an important role in the regulation of neuroplasticity and repair of neuronal damage. In addition, its small molecular weight make it crossing the blood-brain barrier conveniently and be easily detected in peripheral fluids. Therefore, miRNAs have the potential to be used as diagnostic markers and therapeutic targets for TBI. This paper aims to review the features of miRNAs and their applications on diagnosis and treatment of TBI, and provide a reference for their potential clinical applications.
