Over past decade, the Iowa gambling task (IGT) has been utilized to test various decision deficits induced by neurological damage or psychiatric disorders. The IGT has recently been standardized for identifying 13 different neuropsychological disorders. Neuropsychological patients choose bad decks frequently, and normal subjects prefer good expected value (EV) decks. However, the IGT has severa...

OBJECTIVE To assess the cardiovascular risk profile, the degree of insulin resistance, and beta-cell secretion in a cohort of subjects with different categories of impaired glucose regulation (IGR): impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and combined IFG/IGT. RESEARCH DESIGN AND METHODS We studied 902 nondiabetic subjects between 30 and 80 years of age, recruited fr...

Since Bechara et al. pioneered its development, the Iowa Gambling Task (IGT) has been widely applied to elucidate decision behavior and medial prefrontal function. Although most decision makers can hunch the final benefits of IGT, ventromedial prefrontal lesions generate a myopic choice pattern. Additionally, the Iowa group developed a revised IGT (inverted IGT, iIGT) to confirm the IGT validit...

OBJECTIVE To identify factors associated with changes in oral glucose tolerance test (OGTT), regardless of fasting glucose (FG). SUBJECTS AND METHODS 377 patients (53.8 ± 15.2 years, 77.7% women and BMI = 31.4 ± 5.9 kg/m²) with no history of diabetes mellitus(DM), underwent OGTT and compared according to the results: normal (NGT), impaired (IGT) and DM. RESULTS 202 patients (53.6%) had alte...

In the U.S., ∼ 21 × 10(6) individuals have type 2 diabetes, and twice as many have impaired glucose tolerance (IGT). Approximately 40-50% of individuals with IGT will progress to type 2 diabetes over their lifetime. Therefore, treatment of high-risk individuals with IGT to prevent type 2 diabetes has important medical, economic, social, and human implications. Weight loss, although effective in...

The Iowa Gambling Task (IGT) developed by Bechara et al. in 1994 is used to diagnose patients with Ventromedial Medial Prefrontal Cortex (VMPFC) lesions, and it has become a landmark in research on decision making. According to Bechara et al., the manipulation of progressive increments of monetary value can normalize the performance of patients with VMPFC lesions; thus, they developed a compute...

Kurzfassung. MITK-IGT ist eine Erweiterung des Medical Imaging Interaction Toolkits, die es ermöglicht Softwareprogramme im Bereich bildgestützte Therapie zu erstellen. Dieser Beitrag stellt die Architektur und Designprinzipien von MITK-IGT vor und vergleicht sie mit anderen Open Source Lösungen. Neben der Ansteuerung von Trackingsystemen und Visualisierungsmodulen liegt der Fokus von MITK-IGT ...

Our objective was to determine whether defects underlying impaired fasting glucose (IFG) are maintained and additive when combined with impaired glucose tolerance (IGT) (representing a progressive form of prediabetes) or are distinct in IFG/IGT (reflecting a parallel form of prediabetes). Volunteers with IFG (n = 10), IFG/IGT (n = 14), or normal glucose tolerance (NGT; n = 15) were matched for ...
