Our understanding of neurosecretory dysfunction after TBI is still insufficient, and the number of patients with neuroendocrine dysfunction caused by craniocerebral trauma may be underestimated, especially the neuroendocrine changes related to HPA axis in the early stage after craniocerebral trauma. Moreover, there are few and fragmentary literature data on the benefits of hormone replacement therapy in patients with neuroendocrine disorders after traumatic brain injury. This requires more studies to further determine the characteristics of pituitary function or hormone disorders in the early stage after traumatic brain injury, which makes it necessary for us to further study the neuroendocrine dysfunction (hormone disorder) in the early stage after craniocerebral injury. To explore the relationship between craniocerebral injury and early hormone disorder by measuring the changes of early hormone levels in patients with TBI is of great significance for the early detection of related complications after craniocerebral injury and the evaluation of the prognosis of patients with craniocerebral injury, and can provide a new diagnosis and treatment plan for early intervention of related complications after TBI.
