Attention Enhancement System using virtual reality and EEG biofeedback

Attention deficit hyperactivity disorder (ADHD) is a childhood syndrome characterized by short attention span, impulsiveness and hyperactivity, which often leads to learning disabilities and various behavioral problems. For the treatment of ADHD, medication and cognitive-behavior therapy has been applied in recent years. Although psychostimulant medication has been widely used for many years, current findings suggest that, as the sole treatment for ADHD, it is an inadequate form of intervention, in that parents don't want their child to use drugs and the effects are limited to the period in which the drugs are physiologically active. On the other hand, EEG biofeedback treatment studies for ADHD have reported promising results not only in significant reductions in hyperactive, inattentive and disruptive behaviors, but also in improvements in academic performance and IQ scores. However, it is too boring for children to finish the whole treatment. The recent increase in computer usage in medicine and rehabilitation has changed the way health care is delivered. Virtual reality (VR) technology provides specific stimuli that can be used in removing distractions and in providing environments that get the subjects' attention and increase their ability to concentrate, and VR technology can hold a patient's attention for a longer period of time than other methods, because VR is immersive, interactive and imaginary. Based on these aspects, we developed the Attention Enhancement System (AES) using VR technology and EEG biofeedback for assessing and treating ADHD children as well as increasing the attention span of children who have attention difficulties.
