I FOUND IT! "Memantine is used to treat memory dysfunction" "The research program will evalute the drug on a larger scale for children, ages 6 to 12, with autism, Asperger's sndrom and mild symptoms on the autism spectrum." Ohio State University is running the study to see if this Alzheimer's medication can be used to treat children. It will evaluate the impact of memantine on social interaction and communications and is one of 85 research sites in the US. In 2004 a preliminary study found that the medicated children were more open and interaction and communication with peers improved.
My quick scan of the article was inaccurate. I thought the medication was available and had been for a few years. Guess it is still in the study stages. Wouldn't it be wonderful if our AS and spectrum difficult children had some help? DDD
