Hope for Autistic Children?
While not enough research has been done for any conclusions to be drawn, a recent study on autistic children shows promise. Autistic children had previously been found to have very high levels of the "bad" bacteria, clostridia, in their intestines. When given a specially designed probiotic meant to decrease the levels of clostridia and increase the levels of "good" bacteria in their systems, their autistic symptoms decreased.
In this study conducted by Professor Glen Gibson of Reading University, parents noticed such obvious improvements in their autistic children's behavior and concentration that they knew their children were not on a placebo. When their children were due to be switched to the placebo for the remainder of the blind study, they refused to cooperate, causing the clinical trials to be incomplete.
While I would not present this as a magic bullet to a parent of an autistic child, I've never heard of probiotic supplements hurting anyone. It might not be a bad thing to try. They can be found at health food and vitamin stores. Having no idea what blend was used for the trial or at what dosages, I would probably pick up a formulation containing a variety instead of only Lactobacillus Acidophilus. (Of course, check with a doctor since I am not qualified to give medical advice.)
Actually, if I were the parent of an autistic child, I would track down Professor Gibson and his original study. If anyone finds out more about this issue, please let me know.
