Hippocampal volume in healthy controls given 3-day stress doses of hydrocortisone.

In animal models, corticosterone elevations are associated with hippocampal changes that can be prevented with phenytoin. In humans, Cushing's syndrome and long-term prescription corticosteroid use are associated with a reduction in the hippocampal volume. However, little is known about the effects of short-term corticosteroid administration on the hippocampus.

Cognitive changes associated with ADT: a review of the literature.

The use of androgen deprivation therapy (ADT) has increased since the early 1990s after early detection efforts and greater use of the prostate-specific antigen (PSA) test. Although ADT is associated with favorable clinical outcomes, ADT has been associated with an increased risk for cardiovascular disease, increased serum cholesterol, triglycerides, insulin resistance, body mass index and fat body mass. Here we review findings from 11 clinical studies examining the effects of ADT on cognition as measured by standardized tests in cognitive domains such as verbal and spatial memory.

Sex-specific associations between peripheral oxytocin and emotion perception in schizophrenia.

Background: We previously reported that higher levels of peripheral oxytocin are associated with lower levels of positive, general, and overall symptoms in women but not in men with schizophrenia. Here we investigate the influence of sex, sex steroid hormone fluctuations, and peripheral oxytocin levels on emotional processing in men and women with schizophrenia.

Method: Twenty-two women with schizophrenia and 31 female controls completed the Penn Emotion Acuity Test (PEAT), a facial emotion recognition and perception task, during two menstrual cycle phases: 1) early follicular (Days 2-4; low estrogen/progesterone) and 2) midluteal (Days 20-22; high estrogen/progesterone).
