Medical treatment of autism is still a matter of dispute. Medications used are mainly aimed to treat the comorbid symptoms, such as epilepsy, tics, obsessive-compulsive or hyperactive behaviors (Wiznitzer, 2005). Although many efforts were invested in establishing a model of autistic pathophysiology, no such model is currently accepted, and there is no evidence for an efficient treatment of the core autistic symptoms (Wiznitzer, 2005).
