OBJECTIVES: I. Evaluate whether chronic hypercortisolemia is specifically toxic to hippocampal cells and causes structural reduction of hippocampal volume in patients with Cushing's syndrome.
II. Determine whether reduced hippocampal volume is associated with specific memory dysfunction.
III. Examine the relationships of adrenal androgen to hippocampal volume and memory dysfunction.
IV. Examine the reversibility of hippocampal structural changes and cognitive dysfunction after cortisol levels are normalized.
PROTOCOL OUTLINE: Patients undergo a psychiatric evaluation for mood and cognition during confirmation of diagnosis. Neuropsychologic exams include pencil and paper test and a cognitive assessment.
Endocrine studies include dexamethasone and corticotropin-releasing hormone stimulation tests. The hippocampal complex volume is assessed with coronal magnetic resonance imaging.
There is a follow-up 1 year after the initiation of treatment.
Primary Purpose: Screening

OBJECTIVES: I. Determine whether Cushing's syndrome and stress-induced pseudo-Cushing's syndrome can be differentiated by evaluating endogenous corticotropin-releasing hormone activity.
Cushing's syndrome is a relatively rare disorder caused by prolonged exposure to high levels of the glucocorticoid hormone cortisol. Cushing's syndrome may result from elevated endogenous ...
This is a prospective, multi-center, case-control study where neurocognitive function will be evaluated in 36 patients with Cushing syndrome (CS) and 36 controls matched for age, gender an...
The study aim is to investigate the efficacy and safety of Osilodrostat in patients with Cushing's syndrome due to causes other than Cushing's disease in Japan.
OBJECTIVES: I. Study the relationship between dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and disorders of mood, vegetative function, and cognition in patients with Cus...
Ectopic Cushing syndrome is a form of Cushing's in which a tumor outside the pituitary gland produces adrenocorticotropic hormone (ACTH). Small cell carcinoma and carcinoid of the lung comprises half ...
The aim of this study was to determine the frequency of central thyroid dysfunctions in Cushing's syndrome (CS). We also aimed to evaluate the frequency of hyperthyroidism due to the syndrome of the i...
Ectopic Cushing's syndrome (ECS) is a rare condition caused by ACTH secretion by extrapituitary tumors. Its low frequency makes it difficult to acquire experience in its management. The aim of this st...
Cushing's syndrome is rarely caused by the secretion of cortisol from the ovarian tumors. It is important to determine whether the ovarian tumor is capable of secreting cortisol or not in clinical dec...
To assess whether adrenalectomy may improve biochemical and metabolic impairment for patients with subclinical Cushing syndrome (SCS) due to adrenal incidentaloma (AI) compared with conservative manag...
A condition caused by prolonged exposure to excess levels of cortisol (HYDROCORTISONE) or other GLUCOCORTICOIDS from endogenous or exogenous sources. It is characterized by upper body OBESITY; OSTEOPOROSIS; HYPERTENSION; DIABETES MELLITUS; HIRSUTISM; AMENORRHEA; and excess body fluid. Endogenous Cushing syndrome or spontaneous hypercortisolism is divided into two groups, those due to an excess of ADRENOCORTICOTROPIN and those that are ACTH-independent.
Sampling of blood levels of the adrenocorticotropic hormone (ACTH) by withdrawal of blood from the inferior petrosal sinus. The inferior petrosal sinus arises from the cavernous sinus and runs to the internal jugular vein. Sampling of blood at this level is a valuable tool in the differential diagnosis of Cushing disease, Cushing syndrome, and other adrenocortical diseases.
An inhibitor of the enzyme STEROID 11-BETA-MONOOXYGENASE. It is used as a test of the feedback hypothalamic-pituitary mechanism in the diagnosis of CUSHING SYNDROME.
Excess production of ADRENAL CORTEX HORMONES such as ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and/or ANDROSTENEDIONE. Hyperadrenal syndromes include CUSHING SYNDROME; HYPERALDOSTERONISM; and VIRILISM.
A small tumor of the anterior lobe of the pituitary gland whose cells stain with basic dyes. It may give rise to excessive secretion of ACTH, resulting in CUSHING SYNDROME. (Dorland, 27th ed)
