Internet technologies have made rapid progress, bringing convenience to our daily life. On the other hand, Internet overuse (IOU) and Internet addiction (IA) have reportedly become serious health and social problems across the globe. Recently Internet gaming disorder criteria have been proposed in the section of Conditions for Further Study of DSM5. Many surveys have reported that many IOU & IA patients have contracted other mental disorders and exhibit some psychiatric and physical symptoms (e.g., weight loss, reduced ability to exercise, nutrition disorder). Attention Deficit Hyperactivity disorder (ADHD), sleeping disorders, depression, obsessive compulsive disorder, and phobic anxiety disorder are extremely common comorbid mental disorders (CMD) with IUD & IA. Because CMD breaks the usual rhythm of the activities of daily living of IOU & IA patients (e.g., eating meals and sleeping), and prevents the affected patients from participating in social activities (e.g., going to schools or work, participating in sports or other hobbies), CMD causes exacerbation of all IOU & IA symptoms. It has been reported that effecting a cure of some aspects of CMD often leads to the relief of IOU & IA. The diagnosis and the treatment of CMD are therefore very important.
