Ruth Hopkins: Scientific evidence of intergenerational trauma
Posted: Monday, November 28, 2011
"Epigenetics may provide hard scientific evidence of intergenerational trauma among American Indians and link it directly to diseases that currently afflict us, like cancer and diabetes. The term “intergenerational trauma” has been used to describe the cumulative effects of trauma experienced by a group or individual that radiates across generations. For natives, intergenerational trauma has presented itself in the form of genocide, disease, poverty, forced assimilation via removal of children from their families to boarding schools, the seizure and environmental destruction of homelands, and other routes of European colonization. The effects of intergenerational trauma include substance abuse, depression, anxiety, and a variety of other emotional problems. Emotional stress has also shown to effect gene expression via the epigenome. Studies show that the withholding of affection by a mother elicits brain changes in her infant that impairs their response to stress as an adult.
Epigenetics offers remarkable potential for the prevention of disease among American Indians as well. We can use epigenetic inheritance to restore the action of our genetic code from one generation to the next. Once environmental stressors are removed and behavior is corrected, our DNA will revert to its original programming. We could cure diabetes through behavioral changes that allow our epigenome to operate correctly. The elimination of toxins and pollutants could greatly reduce the incidence of cancer and birth defects. Such modification of environmental exposures and behaviors will restore and even improve the overall health and capacity of our genetic line."
