Autoantibodies to the smaller isoform of glutamate decarboxylase (GAD) can be found in patients with type 1 diabetes and a number of neurological disorders, including stiff-person syndrome, cerebellar ataxia and limbic encephalitis. The detection of disease-specific autoantibody epitopes led to the hypothesis that distinct GAD autoantibodies may elicit specific neurological phenotypes. We explo...

Intolerance of uncertainty (IU) has been suggested to reflect a specific risk factor for generalized anxiety disorder (GAD), but there have been no systematic attempts to evaluate the specificity of IU to GAD. This meta-analysis examined the cross-sectional association of IU with symptoms of GAD, major depressive disorder (MDD), and obsessive-compulsive disorder (OCD). Random effects analyses w...

Cytoplasmic islet cell antibodies are well-established predictive markers of IDDM. Although target molecules of ICA have been suggested to be gangliosides, human monoclonal ICA of the immunoglobulin G class (MICA 1-6) produced from a patient with newly diagnosed IDDM recognized glutamate decarboxylase as a target antigen. Here we analyzed the possible heterogeneity of target antigens of ICA by ...

A number of patients with type 2 diabetes are GAD antibody positive. A Diabetes Outcome Progression Trial (ADOPT) is a randomized, double-blind clinical trial in recently diagnosed drug-naive patients with type 2 diabetes that allows for the evaluation of GAD positivity in the context of anthropometric and biochemical characteristics. Of the 4,134 subjects enrolled in ADOPT for whom GAD status ...

The objective of this paper is to provide a review on available data to date on the epidemiology of GAD in Europe, and to highlight areas for future research. MEDLINE searches were performed and supplemented by consultations with experts across Europe to identify non-published reports. Despite variations in the design of studies, available data suggest that (a) about 2% of the adult population ...

OBJECTIVE The main aim of the present research was to evaluate the coherence of generalized anxiety disorder (GAD) psychopathological pattern, the robustness of its diagnostic criteria, and the clinical utility of considering this disorder as a discrete condition rather than assigning it a dimensional value. METHOD The study was designed in a purely naturalistic setting and carried out using ...

Cholinergic and GABAergic neurons in the medial septum-diagonal band of Broca (MS-DB) project to the hippocampus where they are involved in generating theta rhythmicity. So far, the functional properties of neurochemically identified MS-DB neurons are not fully characterized. In this study, MS-DB neurons recorded in urethane anesthetized rats and in unanesthetized restrained rats were labeled w...

Background and Objectives: To describe patterns of healthcare utilization among patients with generalized anxiety disorder (GAD) in general practitioner (GP) settings in Germany. Methods: Using a large computerized database with information from GP practices across Germany, we identified all patients, aged ≥ 18 years, with diagnoses of, or prescriptions for, GAD (ICD-10 diagnosis code F41.1) be...

The diagnostic stability and long-term prognosis of generalized anxiety disorder (GAD) remain the subjects of considerable controversy. We report the results of an investigation of the long-term outcome of an original sample of 44 subjects who participated in a medication trial. Subjects were reinterviewed approximately 16 months after completion of the study, using structured interviews. Fifty...

OBJECTIVE To describe the prevalence of generalized anxiety disorder (GAD) in a community-dwelling population aged 80 years and older. Also to compare sleep patterns, cognitive function and prevalence of other psychiatric conditions between healthy controls and GAD subjects. METHODS DSM-IV criteria were used to diagnose GAD. A representative random sample of 77 community-dwelling subjects (35...
