Abstract
Chronic exposure to elevated glucocorticoid levels in Cushing's syndrome (CS), is associated with deficits in cognitive function and in emotion. The hippocampus plays a crucial role in the behavioral manifestations of the syndrome as it is richest in glucocorticoid receptors and is thus particularly vulnerable to glucocorticoid excess. The wide distribution of glucocorticoid receptors throughout the cerebral cortex, however, suggests that several cognitive functions can also be affected by the dysregulation of glucocorticoids. In this study, we investigated how an excess of glucocorticoid hormones affects cognitive processes. Nineteen patients with chronic hypercortisolemia due to CS were compared to healthy controls matched for age, sex, education, and occupation in tests of processing of visual and spatial information, memory, reasoning and concept formation, language and verbal functions, and attention. Multivariate and univariate analyses revealed overall differences in tests of treatment of visual and spatial information, reasoning and concept formation as well as in verbal and language performance, with poorer performance from CS patients. Differences were also observed in nonverbal aspects of memory and in attention tasks. The results suggest that chronic exposure to elevated levels of cortisol is associated with deficits in several areas of cognition, particularly those involving processing of selective attention and visual components. This study also shows that hormones play an important role in the modulation of cognitive function and that their influence on cerebral structure and function merits closer scrutiny.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
