OBJECTIVE To evaluate the risk of cancer among patients with generalized anxiety disorder (GAD) in a nationwide population-based dataset. METHODS We recruited newly-diagnosed GAD patients aged 20 years or older without antecedent cancer from the Taiwan National Health Insurance Research database between 2000-2010. Standardized incidence ratios (SIRs) of cancers were calculated in GAD patients...

Although mild worry is normative, children with Generalized Anxiety Disorder (GAD) experience worry that is intense, difficult to control, and impairing. Common worries of children with GAD may relate to perfectionism, performance, social situations, family, community/world events, or health. GAD co-occurs not only with other internalizing disorders (e.g., depression) but also with externalizin...

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...

Although most individuals with insulin-dependent diabetes mellitus (IDDM) have autoantibodies to glutamic acid decarboxylase (GAD), antibodies to GAD are also present in some individuals with a low risk of developing diabetes. The GAD autoantibodies of IDDM are specific for the GAD65 isoform, do not bind denatured GAD protein, and target epitope(s) dependent on conformation of the protein. Howe...

Generalized anxiety disorder (GAD) is a common illness with diagnostic criteria that have changed substantially over time. Symptoms of GAD overlap with those of major depressive disorder to such an extent that studying one disorder without studying the other may be impossible. Such an overlap, combined with potentially inappropriate diagnostic criteria for GAD, makes diagnosing and researching ...

We report on the use of the Penn State Worry Questionnaire (PSWQ) to identify individuals with generalized anxiety disorder (GAD). Fifty individuals with primary or secondary GAD and 114 individuals with social anxiety disorder (without GAD) completed the PSWQ. In receiver operating characteristic analyses, a score of 65 simultaneously optimized sensitivity and specificity in discriminating ind...

No correlation was found between glutamate decarboxylase (GAD) activity and the ability of Escherichia coli K-12 strains to grow on glutamate. A gene, gad, determining GAD activity maps near gltC, which controls glutamate permease.

BACKGROUND There is controversy about differential meaningfulness between comorbid generalized anxiety disorder (GAD)/ major depressive disorder (MDD), the corresponding "pure" disorders and subthreshold conditions. We compared subjects who met DSM-IVTR criteria of symptoms and functional impairment for comorbid GAD/MDD, versus those with GAD, MDD, subthreshold conditions, and without significa...

BACKGROUND Whilst studies suggest that generalized anxiety disorder (GAD) represents a considerable health care burden in Europe, there is a paucity of published evidence. This study investigated the burden of illness associated with GAD across five European countries (France, Germany, Italy, Spain, and the UK). METHODS Information from the 2008 European National Health and Wellness Survey da...
