Autism-treatment study dropped
A government agency has dropped plans for a study of a controversial autism treatment that critics had called an unethical experiment on children.
The National Institute of Mental Health said in a statement Wednesday that the study of the treatment -- called chelation -- has been abandoned. The agency decided the money would be better used testing other potential therapies, the statement said.
The study had been on hold because of safety concerns after another study published last year linked a drug used in the treatment to lasting brain problems in rats.
