Introduction Traumatic brain injury (TBI) is considered a global health crisis. It results in injury to the brain from an external impact leading to severe disability, with higher incidence statistics recently observed in young adults and elderly individuals. Purpose The review aims to analyze current research findings explaining the prevalence, incidence, and demographics of such injuries stressing the need for enhanced prevention and management techniques. The pathophysiology involves a complex cascade of biochemical and cellular events, which results in necrotic-apoptotic neuronal cell death. Method The review synthesizes current research on TBI, highlighting epidemiological data, advanced diagnostics, and effective rehabilitation strategies like physical and cognitive therapy. Findings Traumatic Brain Injury is an important public health issue with high morbidity and mortality rates causing extreme damage to a person, such as comas, catatonic states for various years, or lifelong injury or demolition. Early diagnostic imaging techniques include CT, MRI, advanced neuroimaging methods, and blood-based biomarkers. In the acute setting, initial management is directed toward stabilizing and preventing secondary injuries and early mobilization. The goals of rehabilitation are to promote the highest level of functional independence and physical function, cognitive functions, and social integration. Conclusion This review highlights that the use of new rehabilitation technologies, such as VR-based and robot-assisted therapies, might lead to improved recovery. Long-term supportive care combined with community integration is mandatory for enhancing quality of life. A systematic multidisciplinary team approach and family support are needed for traumatic brain injury survivors.
