Look out! Can trauma to the Children, grandchildren Descending

Natural disasters and terror attacks not only causes psychological disorders, but also the biological impact. Trauma victims who felt able to trigger changes in DNA structure, so it can be passed on to offspring in the next generation.

This occurs in the offspring of survivors in the Holocaust or the massacre of Jews by the Nazis. Although no direct experience, most of whom have low cortisol levels are generally triggered by post traumatic stress disorder (PTSD).

In another study, Prof. Eric Richard of the University of St. Louis revealed a similar pattern to the victims of World War II. Offspring, especially the female had a 2 times higher risk for schizophrenia (crazy).

Both examples show that trauma is not just a psychological disorder. This disorder is believed to provide a biological effect, because the only factor that determines the inherited trait is the structure of DNA or deoksiribo nuleus.

Experts suspect that this phenomenon occurs because of trauma triggers changes in the structure of DNA. That change is called DNA methylation, the addition or subtraction of methyl groups one of the genes in a person who experienced trauma.

To prove these allegations, Prof. Isabel Mansuy from the University of Zurich conducted experiments with rats. Quoted from the Telegraph on Wednesday (24/11/2010), he separated pups from their mothers who experience stress, to be combined with healthy rats.

Apparently in its development, children are more prone rats stressed though not stay the same cage with its mother that it was stress. This means that children inherit the rats were more easily risk factor for stress.
