What happens to a person who has lead poisoning?

Wide spectrum. Lead poisoning may have no symptoms at all to seizures, coma and death if severe exposure. The vast majority of youngsters who have elevated levels have no symptoms until they show mild learning disabilities, the "slow" kid in the class. This can be prevented by early screening and intervention if levels elevated. We screen every child in our office between 9 & 12 months and again from 18-24 months.
