Abstract：
BACKGROUND:Athletes, military personnel and mobility-declined elderly people are prone to repetitive mild traumatic brain injury (rmTBI). The injury does not cause acute pathological changes, but leads to chronic neurodegeneration, long-term cognitive dysfunction and even chronic traumatic encephalopathy (CTE). Many existing rmTBI animal models reported uncontrollable adverse effects and long experiment period. Therefore, an improved model needs to be designed. NEW METHOD:Our rmTBI mouse model is a modification of the closed head injury method using electronic controlled cortical impact system. Discontinuous 4 impacts with 48-h interval were performed. A key facet of the model is the use of our designed molded acrylic cast and concave metal disc (as a helmet). They could scatter and transmit hitting power to the whole brain, thus produced a mild diffused injury. The procedure does not require scalp incision or craniotomy, which allows the impacting to be completed in 2 min. RESULTS:Our model did not induce acute macroscopic brain damage and brain edema. It could lead to sustained neuroinflammation and chronic neurodegeneration in injured brain, and resulted in cognitive dysfunction within 5 weeks post-injury. COMPARISON WITH EXISTING METHODS:Previously reported adverse effects including skull fractures, hemorrhage and brain tissue loss were not observed in our model. An experiment period of 5 weeks was allowed for observing chronic neurodegeneration and cognitive dysfunction. CONCLUSIONS:Our model is beneficial to use for simplicity, reproducibility and time saver. It could serve as a platform for research on the pathogenesis, diagnosis and potential therapeutics for rmTBI and CTE.
