Pituitary function in subjects with mild traumatic brain injury: a review of literature and proposal of a screening strategy.

Traumatic brain injury (TBI) is an important public health problem all over the world. The level of consciousness of the patients and the severity of the brain injury is commonly evaluated by the Glascow Coma Scale as mild, moderate and severe TBI. When we consider the high frequency of mild TBI (MTBI) among the all TBI patients the burden of the pituitary dysfunction problem in this group could not be ignored. However, one of the most important and still unresolved questions is which patients with MTBI should be screened for hypopituitarism? Another type of head trauma which could be considered as the subgroup of MTBI is sports related chronic repetitive head trauma. Therefore, in this review we will discuss the frequency, characteristics and current management of pituitary dysfunction in patients with MTBI including the subjects exposed to sports related chronic mild head trauma.
