The book provides a comprehensive exploration of the relationship between nutrition and traumatic brain injury (TBI). Divided into two sections, the book covers various aspects of TBI, from its biomechanics and pathophysiological changes to evidence-based clinical guidelines and experimental models. Section I covers the background of TBI, including the definition and biomechanics of TBI, an understanding of pathophysiological changes that occur in the brain, and the importance of evidence-based clinical guidelines for effective TBI management. The section also delves into experimental models of TBI and the role of biomarkers in diagnosing and assessing TBI. Furthermore, it explores early feeding guidelines following TBI, emphasizing the significance of nutrition in the recovery process. Section II focuses on the connection between nutrition and TBI. It examines the concept of resilience and nutri-protection against TBI prior to the injury, highlighting strategies to enhance the brain's ability to withstand trauma. The book then explores the role of various nutrients and dietary components in TBI, such as antioxidants, branched-chain amino acids, choline, creatine, ketogenic diet, magnesium, polyunsaturated fatty acids (EPA and DHA), polyphenols, vitamin D, and zinc. Each topic is explored in depth, considering their impact on TBI outcomes and potential therapeutic applications. Furthermore, this section delves into nutritional interventions for TBI management. It addresses the selection of appropriate nutritional interventions and mechanistic targets for effective treatment. The section also explores the integration of nutrition into clinical practice guidelines for TBI and the emerging field of nutrigenomics, which investigates the interaction between nutrition and the genetic factors involved in TBI. Additionally, the section discusses the role of pharmacognosy in TBI research and provides nutritional recommendations for TBI management, considering the diverse needs of individuals affected by TBI. The book contributes to advancing the understanding and management of TBI by exploring the background, highlighting the importance of nutrition, and offering insights into nutritional interventions with potential implications for both preventive and therapeutic approaches. The book is a great resource for students and brain/neuroscience researchers.
