There is no specifically marked medicine for the treatment of autism. A number of approaches have been used in evaluating the safety and efficiency of pharmacological treatments of both children and adults with autism. Two study parameters are particularly important, the presence of “blind” and control groups. The highest quality studies utilize equally “blind” and control procedures as well. They have to be performed at multiple sites with a large number of subjects.Research evaluating medicine proposed for treatment of autism, is on the increase. There is accelerated emphasis on medicine testing and better information on treatments should be more available than in the past. In this article, the following classes of medicine and therapies will be discussed: possible future medicine treatments - such as oxytocin, tetrahydrobiopterin and ampakines, hormone therapies, anti-yeast therapies, vitamin therapies, dimethylglycine, alpha lipoic acid and diet therapies.
