Here, we examined the long-term outcome in patients treated for CS by assessing the extent to which the detrimental effects of glucocorticoid (GC) excess on cognition can be reversed three years after corrective surgery. A battery of neuropsychological tests, including tests of attention, visuospatial processing, learning and memory, and executive functioning were administered pre-treatment and 12, 24 and 36 months post-treatment. We included 18 patients with endogenous CS recruited before surgical treatment and 18 controls matched for age, sex and education. CS patients performed worse than controls on tests of attention, executive functioning and nonverbal aspects of memory. Moreover, at 36 months following eucortisolism, executive function performance and, to a lesser extent, attention tasks showed limited change compared to pre-treatment testing. Chronic hypercortisolism is accompanied by a deleterious impact on aspects of cognitive function. This negative effect on attention, executive performance and nonverbal memory seen in patients with CS suggests a differential effect of excess GCs upon different brain areas and networks. This influence persists years after the return to normal cortisol secretion levels.

Determined to what extent, if any, deficits in verbal reasoning abilities are observed in Parkinson's disease (PD) Ss. 38 PD Ss (mean age 65.1 yrs) and 19 controls participated in a battery of 7 tests, including 2 verbal fluency tests, a lexical test, a similarities test, a validated French version of the California Verbal Learning Test, an invited inference, and a verbal logical reasoning test. While findings do not show generalized impairment in linguistic functions, PD Ss performed poorly on several tasks, suggesting that complex ...
