Not only trauma but also the reversal of trauma is inherited [EurekAlert.com]

 

Traumatic experiences in childhood increase the risk of developing behavioral and psychiatric disorders later in life. It is also known that the consequences of a trauma can likewise be observed in the children of people affected even if those children have themselves not experienced any trauma. However, childhood trauma in some conditions can also help individuals deal better with difficult situations later in life. This ability, too, is passed onto following generations. These findings have recently been uncovered by Isabelle Mansuy, Professor of Neuroepigenetics at the University of Zurich and ETH Zurich, during investigations carried out in mice.

A positive environment reverses behavioral symptoms

Mansuy's team of researchers has now demonstrated for the first time that such trauma-related behavioral alterations are reversible in mice. If male mice exposed to trauma in early postnatal life live in pleasant conditions as an adult, their behavior and the behavior of their offspring returns to normal. "Long after the traumatic experiences themselves, living in enriched conditions reverses the behavioral symptoms in adult animals and also prevents the transmission of these symptoms to the progeny", summarizes Isabelle Mansuy the new findings.
