Long-lasting lead damage
From the U.S. Department of Health and Human Services.
A study indicates people may never outgrow the damage that lead does to the brain. At Cincinnati Children’s Hospital Medical Center, Kim Cecil saw that in brain imaging of adults who were exposed to high levels of lead when they were children.
Cecil says adults who had higher lead exposure as children were more likely to have decreased activity in parts of the brain associated with attention and controlling impulses.
``What our study is showing is that, long after this exposure is over, the effects are irreversible.’’
Cecil says it’s another reason to keep kids free of things like lead-based paint.
The research, which was supported by the National Institutes of Health, was presented at a meeting of the Radiological Society of North America.
