【medical-news】赌博成瘾也是病？
Gambling addicts don't learn from their mistakes, according to a study published today in the open access journal Clinical Practice and Epidemiology in Mental Health. The problem could be explained by a kind of mental rigidity that leads to harmful compulsive behaviour in sufferers.
Donatella Marazziti of the University of Pisa and colleagues explain that pathological gambling revolves around the uncontrolled impulse to gamble, with serious consequences for the individual and their family. Its cause, however, is unclear. Scientists have suggested that environmental factors and a genetic predisposition play a part, affecting chemical signals in the brain.
In order to home in on the underlying cause, the Pisa team evaluated a group of 15 male and 5 female pathological gamblers. They carried out various neuropsychological tests in order to explore which areas of the brain are related to the disorder. The tests included the Wisconsin Card Sorting Test (WCST), the Wechsler Memory Scale revised (WMS-R) and the Verbal Associative Fluency Test (FAS). Each of which can assess particular problem-solving abilities. They compared the results with those of healthy individuals.
They found that the pathological gamblers scored well in all tests except the card sorting. In this test, the patients had great difficulty in finding different ways to solve each problem in the test as they worked through them, whereas the healthy individuals got better with practice.
"Our findings show that in spite of normal intellectual, linguistic and visual-spatial abilities, the pathological gamblers could not learn from their mistakes to look for alternative solutions in the WCST," say the researchers. This suggests that there are differences in the part of the brain involved in this kind of problem solving, the prefrontal region. "These differences might provoke a sort of cognitive 'rigidity' that predisposes a person to the development of impulsive or compulsive behaviour, leading to pathological gambling."

为了研究家庭的潜在作用, Pisa小组评估了一组由15个男性和5个女性组成的病态赌徒。他们通过开展各种形式的神经心理测验，以探测大脑的哪一部分与不受控制有关.测试包括wcst,WMS-R,FAS这三种。每一项测试都能评估特殊的解决问题的能力。他们将结果与健康人进行了比较.

他们发现了病态赌徒在各种测试中都取得了较好的成绩,除了卡片分类.在这项测试中,当病人去完成这些问题时,他们有难发现不同的方法去解决每一个问题,而健康的人通过实践会做的更好.
