Traumatic brain injury (TBI) was traditionally considered an infrequent cause of hypopituitarism. However recent reports strongly suggest that TBI-mediated pituitary hormones deficiency may well be more frequent than previously thought. As the prevalence of hypopituitarism is not dependent on the severity of the trauma and considering the high number of TBI events in all industrialized countries a screening procedure for detecting hormone deficiencies in all TBI patients is not possible. In the present work a suggestion for screening a subgroup of TBI patients is discussed in order to increase the effectiveness of the whole procedure.
