__ Science Daily__: __Maltreatment Affects The Way Children's Genes Are Activated__

Researchers from the University of Wisconsin have done a study on the affects child abuse has on the development of genes in children. The specific gene is the glucocorticoid receptor gene (UW). This gene has an affect on hypothalamic-pituitary adrenal in rodents. So researchers know that problems with this part of the brain would make it difficult for people to control emotions and stress levels. Researchers studied this gene in 56 children, ages 11-14, through DNA methylation. Half of these children were physically abused (UW). Scientists did find that the children who were abused had increased methylation for the glucocorticoid receptor gene; which can cause complications later on in life like emotional and health problems, such as immune system function depending on when abusive experiences occur to cause lifelong damage in a child. The textbook has a section on abuse causing permanent damage such as PTSD, but does not go into detail on which part of the brain is affected, and how the brain is affected. The textbook also states that developmentalists have found improvement in children who were removed from the abusive environment and placed in foster care (pg.161). This information from the book does correlate with the findings from the research at UW, but the book may later on have direct information on how abuse affects certain systems in the child’s brain.
