It explores the prevalence and characteristics of cognitive impairments post-TBI, delving into the diverse and significant challenges they pose to individuals. The mechanisms and pathophysiology underlying these cognitive impairments are examined, highlighting the complex biochemical, cellular, and physiological changes involved. Furthermore, the article investigates the critical role of personality traits, psychological factors, and social determinants in the recovery and long-term outcomes of TBI. The interplay between these factors underscores the necessity of a holistic approach to TBI treatment and rehabilitation, emphasizing the importance of personalized care. Through this multidisciplinary analysis, the article aims to enhance understanding of TBI impacts, advocate for comprehensive care strategies, and propose directions for future research and policy development to improve the lives of individuals affected by TBI.
