Abstract: Traumatic brain injury is a high morbidity and mortality event and occurs when there is traumatic damage to the scalp, skullcap, cerebral cortex and subcortical areas. In these traumatic events, neurological protection mechanisms act in order to mitigate the deleterious consequences related to the inflammatory response of the nervous tissue, such as neuroplasticity, related to brain cell modeling as a reaction to external stimuli and which functions as an important neurological recovery event, being favored by the activation of the Akt/CREB/BDNF cell signaling axis. Objective: To explain the influence of the Akt/CREB/BDNF signaling axis on the neurological recovery of patients suffering from traumatic brain injury. Methodology: This study is a systematic review of the literature, with a qualitative approach, interpreting and analyzing the data obtained. The guiding question of the study was: "Contributions of the Akt/CREB/BDNF cell signaling axis in recovery from traumatic brain injury". This was followed by the following steps: identifying the topic, selecting the hypothesis or research question, establishing inclusion and exclusion criteria, defining the information and clinical studies to be included in this review study, interpreting the results and presenting the review with a synthesis of knowledge. Discussion of results: Through this work, it was possible to recognize the pathophysiological processes involved in brain injury mechanisms due to traumatic brain injury, specifically those related to neurological recovery from this type of brain injury. To this end, this study focused on the Akt/CREB/BDNF cell signaling axis, since its role in neurological processes such as neuroplasticity and promotion of neuronal survival has been proven. Conclusion: It is clear that traumatic brain injury is a health problem with high morbidity and mortality. Thus, the mechanisms of action of the Akt/CREB/BDNF signaling axis on neuroplasticity and neuronal survival emerge as an important form of neurological recovery for patients who are victims of this subtype of trauma. Further research on this subject is crucial in order to develop possible therapeutic interventions based on this cascade of cellular responses, with the aim of providing a better prognosis for patients affected by traumatic brain injury.
