  Attention Deficit Hyperactivity Disorder is one of the most common
neurodevelopmental disorders in which patients have difficulties related to
inattention, hyperactivity, and impulsivity. Those patients are in need of a
psychological therapy use Cognitive Behavioral Therapy (CBT) to enhance the way
they think and behave. This type of therapy is mostly common in treating
patients with anxiety and depression but also is useful in treating autism,
obsessive compulsive disorder and post-traumatic stress disorder. A major
limitation of traditional CBT is that therapists may face difficulty in
optimizing patients' neuropsychological stimulus following a specified
treatment plan. Other limitations include availability, accessibility and
level-of-experience of the therapists. Hence, this paper aims to design and
simulate a generic cognitive model that can be used as an appropriate
alternative treatment to traditional CBT, we term as "AR-Therapist." This model
takes advantage of the current developments of augmented reality to engage
patients in both real and virtual game-based environments.
