Abstract：
BACKGROUND:Neuropsychological studies in subjects with eating disorders (EDs) have reported conflicting findings, which might be accounted for by several confounding variables, including neuroendocrine changes. METHODS:General abilities, executive functions, attention, and noneffortful learning were assessed in 45 patients with EDs and 45 healthy comparison subjects (HCS). Plasma levels of 17beta-estradiol, cortisol, allopregnanolone, dehydroepiandrosterone and its sulfate metabolite (DHEA and DHEAS) were evaluated in a subsample of patients and HCS. The influence of clinical, demographic, and neuroendocrine variables on neurocognitive performance was explored. RESULTS:Patients were slower than HCS on noneffortful learning and more accurate on a spatial executive task. DHEA and DHEAS were increased and positively correlated with accuracy on the executive task, while cortisol positively correlated with speed of noneffortful learning. CONCLUSIONS:A subtle impairment of noneffortful learning is the only neuropsychological deficit in patients with EDs. Changes in neuroactive steroids influence neurocognitive performance.
