Different treatments which are employed to improve cognitive performance in children with ADHD have certain pros and cons . Although pharmacological treatments are easily applicable and usually useful for treating ADHD, their long-term health effects are still under question [4, 5]. They are also associated with certain side effects such as sleep disturbance, loss of appetite, and growth suppression. Furthermore, psychosocial treatments including training parents and behavioral therapy are effective interventions but results are not maintained in long term [4, 6]. Regarding the limitations of available treatments, new treatment options are needed for ADHD.
