Of course I prefer talking and writing about the most positive
influences on the healthy brains of children. However, there is a an important influence
that can have a very detrimental affect on a developing brain that I have
neglected
to write about previously.
Lead poisoning is an area of awareness I worked on quite a bit
as did my daughter several years ago. With appreciation to Reghan Walsh, I am
very passionate about sharing the article below. Hopefully you will be
motivated to use it in an effort to create greater understanding and touch the
hearts and minds of others toward preventing more innocent children being
affected.
In addition, Rehgan shared the following exciting news with
members on the Worldwide
Brain Team forum:
"Another passionate lead poisoning
prevention advocate is Tamara Rubin. She is making a full-length documentary
about how lead poisoning has such a damaging effect on young children and the
struggles of families with children who have been lead poisoned."

Effects
of Lead Poisoning on Learning, Behavior and Health Over the Life Course
Childhood lead poisoning is the number
one environmental disease in the United States. The detrimental effects of lead
exposure in children have been known for over 100 years. Early research
identified high levels of lead as particularly detrimental to children's
intellectual and behavioral development. However, new studies have discovered
that lower levels of lead, levels once thought to be safe, also cause
considerable damage to children's developmental outcomes.
Young
Children with Lead Poisoning Lead interferes with the normal
development of a young child's brain resulting in lowered IQ, learning
disabilities and developmental delays.
- The discovery of the biological
mechanism of lead exposure explains why lead is so destructive. Lead affects
the internal working of the neurons, the communication between neurons and the
overall structure of the brain.
- Lead poisoning in young children can
result in impaired infant brain development, lowered IQ, hearing loss and
developmental delays such as speech impairment.
- Lead poisoning affects learning
ability as a child ages and is a powerful predictor of school disciplinary problems.
Lead poisoning is associated with a greater likelihood of behavior problems
like aggression and hyperactivity.
- Children who were lead poisoned were
three times more likely to fail fourth grade reading and math tests and more
likely to be suspended when compared to children with minimal lead exposure.
Teenagers Who Were Lead Poisoned as Young Children Teens who were lead poisoned as children are more likely to have
learning, behavioral, physical and mental health problems resulting in
significant negative outcomes.
- Studies show that lead exposure causes
depression and panic attacks in adolescents.
- Lead exposure in young children is
associated with higher rates of teen pregnancy, high school dropout and
juvenile delinquency, especially violent crime.
- Teenagers who were lead poisoned as
children are 5 times more likely to use tobacco in their teenage years.
Research posits that early lead exposure may increase sensitivity to tobacco
addiction and contribute to continued tobacco use.
- Lead interferes in the normal
development of the brain, resulting in a reduction in volume in the frontal
lobe. This is the region of the brain that reasons, judges,
solves problems, and controls impulses and emotional responses.
- Teens who were lead poisoned as a
child are more likely to have problems with their upright balance that may
result in falls or discourage their participation in sports activities. Lead
affects the central nervous system affecting children's long-term injury risk
by harming their balance, coordination and other neuromuscular skills.
- Children who were lead poisoned are
more likely to develop kidney disease as adolescents.
Adults Who Were Lead Poisoned as Young Children Lead poisoning continues to predict negative behavioral, physical
and mental health outcomes for adults who were poisoned as children.
- Violent crimes committed by young
adults are strongly associated with prenatal and childhood lead poisoning. For
each increase of 5 micrograms per deciliter of lead in blood as a child, an individual's
risk of being arrested for committing a violent crime as an adult increases by
50%.
- Childhood lead poisoning increases the
risk of early death from stroke and heart attack as adults. Childhood lead
exposure is also linked to adult kidney disease, cognitive deficits such as
memory loss and Alzheimer's disease.
- Childhood lead exposure has strong
associations with depression, panic attacks and general pessimism about life as
adults.
- Childhood lead poisoning can cause
reproductive problems in both men and women. Men who were lead poisoned can
suffer from sexual dysfunction and testicular cancer. Adverse birth outcomes
such as increased risk of spontaneous abortion, preterm delivery and infant low
birth weight are related to childhood lead exposure. Women are more likely to
develop hypertension when pregnant.
