Reporting Preliminary Findings

While scanning through recent science press releases I came across an interesting study looking at the use of a pharmaceutical grade antioxidant, N-Acetylcysteine (NAC), in the treatment of certain symptoms of autism. This is a small pilot study, but it did have a double-blind placebo controlled design. The press release reports:

During the 12-week trial, NAC treatment decreased irritability scores from 13.1 to 7.2 on the Aberrant Behavior Checklist, a widely used clinical scale for assessing irritability. The change is not as large as that seen in children taking antipsychotics. “But this is still a potentially valuable tool to have before jumping on these big guns,” Hardan said.
