PRIMARY OBJECTIVES: To review evidence that there exists a substantial sub-population of patients with endocrine disorders as a result of traumatic brain injury (TBI) and to underscore the importance of screening patients with TBI considered most at risk for hypopituitarism with the goal of attaining beneficial effects in terms of morbidity and quality of life.

DESIGN AND METHODS: Reviewed recent literature regarding the frequency of TBI-induced hypopituitarism.

MAIN OUTCOMES AND RESULTS: Studies by Kelly DF, Gaw Gonzalo IT, Cohan P, et al. Hypopituitarism following traumatic brain injury and aneurysmal subarachnoid hemorrhage: A preliminary report. Journal of Neurosurgery 2000;93:743-751, Lieberman SA, Oberoi AL, Gilkison CR, et al. Prevalence of neuroendocrine dysfunction in patients recovering from traumatic brain injury. Journal of Clinical Endocrinology and Metabolism 2001;86:2752-2756 and Aimaretti G, Ambrosio MR, Di Somma C, et al. Traumatic brain injury and subarachnoid haemorrhage are conditions at high risk for hypopituitarism. Screening study at 3 months after the brain injury, In press., found that about one-half to one-third of patients with TBI had anterior pituitary hormone deficiencies, including growth hormone (GH) deficiency in 15-21%, and subtle deficiencies in thyroid, adrenal and gonadal axes. One or more hormonal deficiencies produce diverse physical and psychological symptoms that may mimic symptoms attributed to brain trauma and may impair rehabilitation. A more general concern is the fact that hypopituitarism increases the risk of significant morbidity (e.g. ischaemic heart disease) and mortality (shortened life span).

CONCLUSIONS: To attain maximal improvement in mental and physical functioning as well as in quality of life for victims of TBI, it is crucial that anterior pituitary hormonal function be assessed. Appropriate hormone replacement therapy for those patients with both TBI and TBI-induced pituitary function impairment could, for the first time, allow treatment and correction of underlying causes of TBI sequelae rather than merely symptomatic treatment.

Sean Dudas is a California native and remains active and interested in many corners of life. In November of 2015, Sean suffered a moderate traumatic brain injury from a fall; his life since has been solely devoted to the topic of this blog - TBI and other forms of acquired brain injury. With his passions and life as he imagined it to be on an indeterminate hold during his rehabilitation and recovery, he began this blog and a TBI health advocacy group. Through uniform rules of professional responsibility and ethics, he hopes the health advocate profession may be an affordable adjunct to the team needed by every brain injured person and those caring for them. He hopes that this blog will continue educating and supporting survivors of brain injury, their caregivers, and anyone interested in this devastating medical sojourn, alongside the discovery of a new self and a meaningful life outside the treatment environment. Sean is active in supporting mental health and suicide crisis support, various manifestations of trauma in children and adults, and is a Doctor of Law with a focus on health and science law. He is also an athlete, poet, writer, and nature enthusiast.
