Behavioral and learning difficulties in children and Bisphenol
During the nine months between conception and birth, the fetal brain is transformed from instructions in genes to a complex, highly differentiated
mass of organized cells capable of interacting with the outside world and prepared for learning.
Those first nine months lay the groundwork for all of that happens later in life. Get this wrong, and the consequences can diminish a person's
capacity to participate in society and compete throughout life.
Normal brain development is heavily influenced and dependent upon natural hormone signals, brain development is therefore vulnerable to endocrine

Studies show that BPA exposure during pregnancy builds up in the vomb and affect young childrens behavior the girls is especially vulnerable.
In this study, published October 24, 2011, in an advance online edition of Pediatrics, lead author Joseph Braun, research fellow in environmental
health at HSPH, and his colleagues found that gestational BPA exposure was associated with more behavioral problems at age 3, especially in girls.
The researchers collected data from 244 mothers and their 3-year-old children in the Health Outcomes and Measures of the Environment Study, conducted
in the Cincinnati area. Mothers provided three urine samples during pregnancy and at birth that were tested for BPA; their children were tested each
year from ages 1 to 3. When the children were 3 years old, the mothers completed surveys about their children's behavior.
BPA was detected in over 85% of the urine samples from the mothers and over 96% of the children’s urine samples. The researchers found that maternal
BPA concentrations were similar between the first sample and birth. The children’s BPA levels decreased from ages 1 to 3, but were higher and more
variable than that of their mothers.
After adjusting for possible contributing factors, increasing gestational BPA concentrations were associated with more hyperactive,
aggressive, anxious, and depressed behavior and poorer emotional control and inhibition in the girls. This relationship was not seen in the
