Effects of traumatic brain injury and subarachnoid hemorrhage on anterior pituitary function

Traumatic brain injuries and subarachnoid hemorrhage are frequent events in Spain. Both are well recognized causes of anterior hypopituitarism, the prevalence ranging from 20 to 80% according to recent series. Consensus is lacking on how to assess pituitary function after the injury, although periodic assessment is clearly needed because hypopituitarism may appear at any time in the first year after the event. Hormone replacement when necessary helps recovery and reduces morbidity and mortality.
