The error-related negativity (ERN) is a negative deflection approximately 50ms following an erroneous response, and is thought to reflect activity of the anterior cingulate cortex (ACC), a region of the medial prefrontal cortex implicated in the pathophysiology of a number of affective disorders, including generalized anxiety disorder (GAD). Pathological worry, the hallmark of GAD, has been lin...

Self-observations of cognitions during episodes of anxiety were examined in 38 patients with generalized anxiety disorder and 36 patients with panic disorder. Two independent observers who where blind to the diagnoses categorised the cognitions. The inter-rater reliability was high (mean kappa 0.82). The GAD-patients had significantly more cognitions in the following categories: interpersonal c...

Generalized anxiety disorder (GAD) and major depressive disorder (MDD) demonstrate a strong relationship to each other at both genotypic and phenotypic levels, and both demonstrate substantial loadings on a higher-order negative affectivity factor [see Watson, 2005: J Abnorm Psychol 114:522-536]. On the basis of these findings, there have been a number of calls to reclassify GAD in the same cat...

A previous Generalized Anxiety Disorder Impact Survey (GADIS I) performed on 15,399 Belgian patients consulting their primary care physicians, revealed high prevalences of generalized anxiety disorder (GAD) and major depression (MD) with important regional differences. The objective of this study (GADIS II) was to replicate previous findings and to evaluate the role of socioeconomic factors in ...

Objective: To review studies quantifying the burden of generalized anxiety disorder (GAD) in Germany. Methods: A review of 17 original English-language studies on the human, health care and economic burden of GAD in Germany, identified in electronic databases (MEDLINE/ EMBASE: 1990-2008) and published bibliographies. Results: Nationally representative data indicate that GAD is more prevalent in...

Concerns have been raised that the DSM-IV requirements of 6-month duration, excessive worry, and three associated symptoms exclude a substantial number of people with clinically significant anxiety from a diagnosis of generalized anxiety disorder (GAD). We examined the implications of relaxing these three criteria for the estimated prevalence and predictive validity of GAD using nationally repr...

OBJECTIVE To review the efficacy of anxiolytics (alprazolam and azapirones) in major depressive disorder (MDD) and that of antidepressants in generalized anxiety disorder (GAD), thereby exploring the possible theoretical and clinical implications of this efficacy. METHOD A Medline literature search was performed for the period January 1980 to September 1997 of randomized, double-blind compari...

The aim of this present study is to examine the efficacy of attribution retraining group therapy (ARGT) and to compare the responses of outpatients with major depression disorder (MDD), generalized anxiety disorder (GAD) and obsessive-compulsive disorder (OCD). We carried out a prospective uncontrolled intervention study with a 8-weeks of ARGT on sixty three outpatients with MDD, GAD or OCD. Ha...

Mental health issues are a growing problem worldwide, and their detection can be complicated. Assessments such as the Patient Health Questionnaire (PHQ-9) Generalized Anxiety Disorder (GAD-7) questionnaire useful tools for detecting depression anxiety, however, due to being self-reported, patients may underestimate own risk. To address this problem, two new assessments introduced, i.e., PHQ-V G...

People are typically faster and more accurate to detect angry compared to happy faces, which is known as the anger superiority effect. Many cognitive models of anxiety suggest anxiety disorders involve attentional biases towards threat, although the nature of these biases remains unclear. The present study used a Face-in-the-Crowd task to investigate the anger superiority effect in a control gr...
