Animal approach-avoidance conflict paradigms have been used extensively to characterize effects of anxiolytic agents and probe neural circuitry related to anxiety. However, there are few behavioral approaches to measure conflict in human populations, limiting the translation of findings from animal conflict tasks to human clinical research. We developed a novel approach-avoidance conflict (AAC)...

The amygdala is believed to play a key role in assigning emotional significance to specific sensory input, and conditions such as anxiety, autism, stress, and phobias are thought to be linked to its abnormal function. Growing evidence has also implicated the amygdala in mediation of the stress-dampening properties of alcohol. In this issue of the JCI, Pandey and colleagues identify a central am...

This study examined the role of the level and variability of happiness, anger, anxiety, and sadness in the development of adolescent-reported anxiety disorder symptoms, depressive symptoms, and aggressive behavior in 452 adolescents (250 male) followed from age 13 to 14. Level and between-day variability of emotions were assessed through adolescent report at 3-month intervals across a 1 year pe...

Parents of children with autism spectrum disorders (ASDs) have been shown to experience increases in stress, depression, and anxiety, which are also associated with child behavior problems related to ASDs. Literature-examining potential mechanisms that underlie the relationship of child behavior problems and parental anxiety/depression in this population are scarce. The current study sought to ...

This study examines nine dynamical and three emotional aspects of behavior in depression and anxiety, singly and comorbidly. The study employs the Structure of Temperament Questionnaire Compact (STQ 77), whose 12 scales assess the energetic, lability and sensitivity aspects of behavior in the physical, social, mental and emotional domains. The STQ 77 was administered to 86 patients with Major D...

In abstinent alcoholics, stress induces negative affect-a response linked to craving and relapse. In rats, repeated stresses at weekly intervals before 5-day ethanol diet sensitize withdrawal-induced anxiety-like behavior ("anxiety") that is blocked by a corticotrophin-releasing factor 1 (CRF-1)-receptor antagonist. Current experiments were performed to identify brain sites that support CRF inv...

Corticotropin-releasing factor (CRF) in the medial prefrontal cortex (mPFC) is suggested to play an important role in mediating fear, anxiety, and depression. The results of the studies of the actions of CRF in the mPFC regarding anxiety-related behavior, however, seem contradictory. In one study, microinjection of CRF into the mPFC produced an increase in anxiety-related behavior on the elevat...

BACKGROUND In Japan and Asia, few studies have been done of physical and sexual abuse. This study was aimed to determine whether a history of childhood physical abuse is associated with anxiety, depression and self-injurious behavior in outpatients with psychosomatic symptoms. METHODS We divided 564 consecutive new outpatients at the Department of Psychosomatic Medicine of Kyushu University H...
