Research progresses on cognitive function and neuroimaging study of internet gaming disorder / 中国医学影像技术

ABSTRACT

With the rapid development of internet technology, internet gaming disorder (IGD) has become a global mental health problem. At present, most of the researches on IGD focus on three aspects, i.e. reward system, suppression control and intertemporal decision-making. With the development of cognitive neuroscience, it becomes popular to use electroencephalogram (EEG), MRI and PET in exploring the neural mechanism of IGD. Previous neuroimaging studies have shown that brain structure and function of IGD patients both changed accordingly compared with healthy controls. Besides, the degree of brain damage is related to the duration of addictive behavior. The recent work in cognitive function and neuroimaging researches of IGD were reviewed in this article, highlighting research methods and corresponding results, in order to provide references for further exploration and scientific research in this area.
