Pathological gambling is classified in the DSM-IV-TR (Diagnostic and Statistical Manual of Mental Disorders) and in the ICD-10 (International Classification of Disease) as an impulse control disorder. The association between impulsivity and pathological gambling remains a matter of debate: some researchers find high levels of impulsivity within pathological gamblers, others report no difference compared to controls, and yet others even suggest that it is lower. In this review we examine the relationship between pathological gambling and impulsivity assessed by various neurocognitive tests. These tests – the Stroop task, the Stop Signal Task, the Matching Familiar Figures Task, the Iowa Gambling Task, the Wisconsin Card Sorting Test, the Tower of London test, and the Continuous Performance Test – demonstrated less impulsivity in gambling behavior. The differences in performance between pathological gamblers and healthy controls on the neurocognitive tasks could be due to addictive behavior features rather than impulsive behavior.

Background: Since surgical repair of tetralogy of Fallot was introduced, follow-up studies have shown that the majority of patients lead actives lives and have no subjective exercise limitation.

Objectives: To examine lung function, cardiopulmonary functional capacity and echo-Doppler assessment of pulmonary pressure in adult patients 20 years after repair of TOF.

Methods: Unselected consecutive patients performed full lung function testing, progressive cardiopulmonary exercise, and echo-Doppler assessments of pulmonary pressure.

Results: Fifty consecutive patients (33 men, 17 women) aged 29 ± 11 years who underwent surgical repair of TOF at age 10.1 ± 10.9 years were enrolled in this study. Patients after TOF showed no restriction (forced expiratory vital capacity 80%, total lung capacity 91%) and had normal oxygen saturation (97%) and 6 minute walking distance (600 meters). Echocardiography showed normal pulmonary pressure and left ventricular ejection function (62%). Cardiopulmonary exercise testing showed mild limitation of exercise capacity with oxygen uptake at maximal effort of 75–78% predicted.

Conclusions: After corrections of TOF the study patients had normal lung function and pulmonary arterial pressure but mild limitation in their exercise capacity.
