OBJECTIVE Cushing's syndrome (CS) is associated with neuropsychological deficits. As the cerebellum plays a key role in neuropsychological functions it may be affected in CS. The aim of this study was to investigate whether patients with CS have a smaller cerebellar volume than healthy controls, and to analyse whether cerebellar volume is associated with(More)
BACKGROUND Findings of brain structural changes in major depressive disorder are still inconsistent, partly because some crucial clinical variables have not been taken into account. AIMS To investigate the effect of major depressive disorder on grey matter volumes. METHOD Voxel-based morphometry was used to compare 66 patients with depression at(More)
CONTEXT Cushing's syndrome (CS) affects cognition and memory. OBJECTIVE Our objective was to evaluate memory and hippocampal volumes (HV) on 3-tesla magnetic resonance imaging (3T MRI) in CS patients and controls. PATIENTS AND METHODS Thirty-three CS patients (11 active, 22 cured) and 34 controls matched for age, sex, and education underwent Rey(More)

CONTEXT AND OBJECTIVE Cushing's syndrome (CS) is caused by a glucocorticoid excess. This hypercortisolism can damage the prefrontal cortex, known to be important in decision-making. Our aim was to evaluate decision-making in CS and to explore cortical thickness. SUBJECTS AND METHODS Thirty-five patients with CS (27 cured, eight medically treated) and(More)
Evaluation of cognitive function in acromegaly has revealed contradictory findings; some studies report normal cognition in patients with long-term cured acromegaly, while others show attention and memory deficits. Moreover, the presence of affective disorders in these patients is common. Our aim was to evaluate memory and decision making in acromegalic(More)
Chronic exposure to excessive glucocorticoid (GC) concentration in Cushing's syndrome (CS) can affect the brain structurally and functionally; ventromedial prefrontal cortex (vmPFC) is rich in GC receptors and therefore particularly vulnerable to excessive GC concentration. Proton magnetic resonance spectroscopy ((1)H-MRS) is a sensitive, non-invasive(More)
Until the last decade, little was known about the effects of chronic hypercortisolism on the brain. In the last few years, new data have arisen thanks to advances in imaging techniques; therefore, it is now possible to investigate brain activity in vivo. Memory impairments are present in patients with Cushing's syndrome (CS) and are related to hippocampal(More)
INTRODUCTION Cushing's syndrome (CS) increases cardiovascular risk (CVR) and adipocytokine imbalance, associated with an increased inflammatory state. Telomere length (TL) shortening is a novel CVR marker, associated with inflammation biomarkers. We hypothesized that inflammatory state and higher CVR in CS might be related to TL shortening, as observed in(More)
This study aims at investigating attention and impulsivity differences between borderline personality disorder and bipolar disorder, as both diseases may share neuropsychological deficits. Differential cognitive outcomes on the Continuous Performance Test-II were observed between disorders, and also when compared to healthy controls.
