May 9, 2001 -- Using a lead-lowering drug to reverse the IQ damage associated with the lead exposure has proved ineffective, the National Institute of Environmental Health Sciences announced today. Walter Rogan, M.D., of NIEHS, and colleagues from the Treatment of Lead-exposed Children Trial (TLC) reported the results in The New England Journal of Medicine (May 10). The TLC study showed that, as expected, drug treatment with succimer lowered blood lead faster than placebo. Treating lead-exposed two-year-olds, however, did not improve scores on psychological, behavioral and IQ tests when the children were followed until age 5 years.
