Cognitive vulnerability and frontal brain asymmetry: common predictors of first prospective depressive episode.

Journal of Abnormal Psychology Cognitive Vulnerability and Frontal Brain Asymmetry: Common Predictors of First Prospective Depressive Episode

Frontal and parietal EEG asymmetries interact to predict attentional bias to threat.

Frontal and parietal electroencephalographic (EEG) asymmetries mark vulnerability to depression and anxiety. Drawing on cognitive theories of vulnerability, we hypothesise that cortical asymmetries predict attention to threat. Participants completed a dot-probe task in which bilateral face displays were followed by lateralised targets at either short (300ms) or long (1050ms) SOA. We also measur...

Pseudo-continuous arterial spin labeling imaging of cerebral blood perfusion asymmetry in drug-naïve patients with first-episode major depression

Many previous studies have reported that regional cerebral blood flow (rCBF) aberrations may be one of the pathological characteristics of depression and rCBF has demonstrated a certain degree of asymmetry. However, studies investigating the cerebral blood perfusion asymmetry changes of drug-naïve patients experiencing their first episode of major depression using pseudo-continuous arterial spi...

The comparison of alpha power, peak alpha frequency, frontal alpha asymmetry between irritable bowel syndrome and healthy people

Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder that is characterized by abdominal pain or discomfort and changed intestinal habits. The aim of This study was the comparison of features of brain oscillations in alpha frequency band by using rest-electroencephalography (EEG) between patients with IBS and healthy control. 11 IBS patients (7 female and 4 male) and ...

Cognitive vulnerability to depressive symptoms in adolescents in urban and rural Hunan, China: a multiwave longitudinal study.

The current multiwave longitudinal study examined the applicability of two cognitive vulnerability-stress models of depression-Beck's (1967, 1983) cognitive theory and the hopelessness theory (Abramson, Metalsky, & Alloy, 1989)-in two independent samples of adolescents from Hunan Province, China (one rural and one urban). During an initial assessment, participants completed measures assessing d...
