I have a DAN doctor and he has recomemded "Authia cream" I can either buy it from him (the doctor) or online...go to msn and type in "authia cream" its about 45 dollars and needs to be refrigerated after you open it....it has made my daughther have eye contact when she had nothing...and alot more energy...so yes it works...twice a day ...once in the morning and once in the afternoon...try it
