the frontal and other lobes of the brains of deceased individuals who had been violent or
erratic, to see if those lobes were not especially poisoned by lead. So the study of lead
encephalopathy by Okazali et al found highest lead in the frontal and the hippokampal
(lateral) cortices, while another study by Hamilton et al on healthy brains, found the
frontal lobe about average in leading. Also might be cited the work of Kato. A study by
Niklowitz found a bulging of the soft parts of the frontal lobe of leaded infants.
Niklowitz points out that lead poisoning creates symptoms in the brain similar, if not
identical, to those of Alzheimer’s disease, a form of premature mental senility. But we so
not seem to be dealing merely with mental deterioration and grand mal seizures. For
example: the son of a painting contractor, who had chewed lead paint and suffered
convulsions, had to be hospitalized at the age of three. Irritability and tantrums, combined
with mental defect, brot about his institutionalization at age 26. An autopsy his death 19
years later revealed that the brain was shrunken, there was a marked loss of neurones and
neural sheathing, and neurofibrillary tangles were massively present. The diffuse brain
atrophy found was most conspicuous in the temporal (lateral) lobes.
On the basis of his analysis of the destruction of higher control levels of the brain by
lead poisoning, Dr. Niklowitz calls plumbism “the silent epidemic.” Other work now in
progress is searching for a link between the rising epidemic of crimes of irrational violence,
and lead poisoning. Niklowitz believes that the basic processes of brain damage and
destruction caused by TEL injections into rabbits can be applied to the massive lead
poisoning which especially the Roman intellectual and political elite suffered. If so, this
would provide a clue to several phenomena. One would be the apparent madness of
emperors such as Caligula, Nero, Commodus, and Elagabalus, some of whom seemed in
their youth to be admirably fitted to rule. Another would be the sadism of the Romans,
with their addiction to spectacles in which, for example, men and women were on occasion
offered to famished wild beasts. A third piece of evidence would be the apparent disastrous
decline of Roman intellect, mainly in the second and third centuries A.D.
Genetic poison
Lead as a possible gene poison has been claimed by many. They argue that lead can alter
the genes, the packets of heredity, and thus perhaps permanently alter future descendants,
naturally changing them for the worse. Koinuma found that husbands exposed to lead in a
storage battery factory had 24.7 percent sterile marriages versus 14.8 percent for non-lead-
workers. Stillbirths were 8.2 percent versus 2.7 percent, and infant mortality 24 percent
versus 19. But in most lead trades and likely this one too, the father can bring home lead on
his clothes that will reach his family; and so can a breeze from a lead works.
Arthralgia
Tanquerel des Planches observed that leads arthralgic pain attacked any of the joints, but
more frequently those in the lower limbs. He described it as a sharp, burning, boring or
simply numbing pain, that could radiate out and encompass the overlying tissue. He made
an important differential diagnostic point when he explained that unlike rheumatoid
arthritis (with which this might be mistaken) lead arthralgia causes no swelling nor
redness. In addition, the leaded patient is constantly moving around, trying to find a
comfortable position, something never seen in arthritics, who prefer to remain still.
Another of the most characteristic signs among lead workers today is the “wrist
drop” a motor paralysis observed among lead workers. But it is hardly ever seen in children
