Traumatic brain injury induced hypopituitarism: the need and hope of rehabilitation.

Traumatic brain injury is a leading cause of death and disability in developed countries. Damage caused by focal and diffuse lesions produces symptoms involving most major medical systems as well as symptoms of neurological and psychological origin. The severity of a traumatic brain injury is difficult to assess, and therefore, an initial accurate prognosis is difficult as well. Present treatments focus on relieving symptoms without adequately addressing the underlying cause of those symptoms. Recent studies have shown anterior pituitary deficiencies to be common amongst survivors of TBI. As many symptoms ascribed to a TBI are similar to the symptoms of hypopituitarism, it is possible that treatment of these deficiencies will improve functioning and the quality of life for survivors of traumatic brain injuries.
