ADHD or ADD (Attention Deficit/Hyperactivity Disorder) is one of the most frequently diagnosed mental and behavioral disorders of children. Children with ADHD are characterized by poor attention and distractibility and/or hyperactive and impulsive behaviors. Although there is no "cure" for ADHD, there are accepted treatments that specifically target its symptoms. The most common standard treatments include medication, psychological or behavioral modification, and educational approaches. However, more and more parents began to worry about the side effects of medication. For this reason, this study proposed a new treatment by using digital console games to assist children who suffer from ADD to improve their attention condition. With the advantages of gaming apparatus, this study intends to improve the effect of behavioral intervention and cognitive remediation therapy for ADD children.
