Abstract

Aneurysmal subarachnoid hemorrhage (aSAH) results from the rupture of an intracranial aneurysm and represents a highly debilitating and devastating disorder. The prevalence rate of neuroendocrine impairment in the acute phase is extremely variable, ranging from 3.8% to 92.3%, depending on the time point considered, the method/test utilized, the clinical severity at admission, and probably also ethnicity. Further studies are needed to clarify such a wide range in neuroendocrine dysfunction in patients with aSAH. The overall neuroendocrine impairment rate in chronic aSAH is in the range 47%–83.3% with specific neuroendocrine impairment varying from 2.5% to 83.3%. The overall pituitary deficiency rate tends to decrease over time after SAH, with recovery of most endocrine and some de novo dysfunctions being reported. Only one study has reported an increase of overall endocrine impairment in the chronic follow-up. Neuroendocrine dysfunction seems to have a high prevalence in aSAH patients, even though its exact impact is not precisely known and is based on contrasting findings. More high-quality studies and trials are necessary before informing guidelines and protocols recommending preventive endocrine screening and related treatment (hormone replacement therapy) on a routine basis. The usage of standardized testing and reporting procedures could significantly move the field forward.
