Many of you may not remember the 1978 Jimmy Carter’s battle with Congress to ban lead from gasoline (both parties opposed him).  In 1979 I moved from NYU to Maryland because my USDA grant application was approved for 2.5 million dollars to study the effects of environmental toxins such as lead, cadmium, mercury, aluminum, arsenic, etc. and organophosphates on brain development from infancy to adulthood.  QEEG and multiple neuropsych tests (administered by licensed psychologists) and measures of school performance and SES and age and nutrition and demographics, etc. for over 1,300 children from 2 months to 18 years of age was collected and placed in databases that today are still used in NeuroGuide and by ANI.

In 1982 I was proud to testify before an EPA committee when, at that time, there was over 200,000 tons of lead consumed in automobile gasoline per year and was spewed throughout the US.  We showed a significant negative linear relationship between I.Q. and QEEG and the body burden of lead.  In the 1980s we also published studies where we concluded that the dopaminergic motor system in QEEG was especially susceptible to lead and the more posterior occipital-parietal regions were especially susceptible to cadmium.

Bottom line is that the only acceptable level of lead is zero lead.   Every atom of lead and cadmium and mercury is a toxin.

In 1983 I received additional funding from NIH and other agencies and eventually extended the QEEG and psychological and demographic database to age 82 in 1989.  The selected subset of individuals that had low levels of lead and cadmium and normal neuropsychological scores and normal development and no history of neurological disorders became the basic foundation of the NeuroGuide normative database in 1989 which is in use by over 5,000 individuals today.

I am copying some of our publications which is a testament to how a team of dedicated and passionate people can make a difference even if it is only a temporary and forgotten difference.
