Delirious Mania in a 77-Year-Old Female.

Delirium is associated with acute episodes of disturbances in attention and awareness along with changes to cognition, including memory deficits and disorientation. Delirious mania (DM) is an unusual phenomenon where symptoms of delirium co-exist with symptoms of mania such as elevated or irritable mood, grandiosity, agitation, and cognitive disorganization. There is no formal agreement upon clinical symptoms for DM, but it generally includes acute onset of confusion, poor orientation, excitation, restlessness, and delusions.

Pregnenolone Reduces Stress-Induced Craving, Anxiety, and Autonomic Arousal in Individuals with Cocaine Use Disorder.

Chronic cocaine use leads to adaptations in stress biology and in neuroactive steroid system. These adaptations are associated with high cocaine craving and increased relapse risk. This study tested whether potentiation of the neuroactive steroid system with the precursor pregnenolone (PREG) affects stress- and cue-induced cocaine craving, anxiety and autonomic response in individuals with cocaine use disorder (CUD).

A cross-national study of factors associated with women's perinatal mental health and wellbeing during the COVID-19 pandemic.

Pregnant and postpartum women face unique challenges during the COVID-19 pandemic that may put them at elevated risk of mental health problems. However, few large-scale and no cross-national studies have been conducted to date that investigate modifiable pandemic-related behavioral or cognitive factors that may influence mental health in this vulnerable group. This international study sought to identify and measure the associations between pandemic-related information seeking, worries, and prevention behaviors on perinatal mental health during the COVID-19 pandemic.

A model of negative emotional contagion between male-female rat dyads: Effects of voluntary exercise on stress-induced behavior and BDNF-TrkB signaling.

Emotional contagion refers to the sharing of emotional states between individuals and can cause depressive behaviors in healthy persons who live with depressed individuals. Negative emotional contagion has been observed in animal models, but the vast majority of studies are short-term and bear little resemblance to long-term human relationships. Thus, the first aim of this study was to establish an animal model of stress-induced negative emotional contagion that develops across time and between pairs.
