A new study by Chinese researchers has found differences in the brain activity of men and women addicted(上瘾的)to Internet gaming.
The study says addicted men have lower impulse control compared with women, indicating that men are more likely to become addicted to internet gaming.
Researchers from Renji Hospital, which is connected with Shanghai Jiaotong University, recruited 105 Chinese participants for the study, which had two groups - one with 32 men and 23 women addicted to gaming, and the other with 30 men and 22 women who were not addicted.
They completed a questionnaire for gaming addiction, and reported their gaming history and number of hours playing per week. Researchers also talked with their families to collect the information.
Through FMRI (磁共振扫描), researchers found that men addicted to gaming had lower brain activity in the brain region associated with impulse control, than nonaddicted men. The lower the activity levels, the poorer the impulse control. Addicted women, however, showed no differences compared with the healthy female group.
Researchers also studied the functional connectivity between brain regions, which were lower in men with addiction than in nonaddicted men, but showed no differences in the female groups.
Although there are some limitations, the findings suggest that activity levels displayed in the brain region could be biomarkers to evaluate the behavioral inhibitions of gaming-addicted men, they said.
Gaming disorder was listed as a mental disorder by the World Health Organization earlier this year. People with the disorder have impaired control over gaming and give it increased priority in their lives-to the extent that gaming takes precedence over other life interests and daily activities.
