Abuse in early childhood permanently alters how the brain reacts to stress, a Canadian study suggests.
Analysis of brain tissue from adults who had committed suicide found key genetic changes in those who had suffered abuse as a child.
The Nature Neuroscience study underpins the impact of stress on early brain development, experts said.
Previous research has shown that abuse in childhood is associated with an increased reaction to stressful circumstances.
But exactly how environmental factors interact with genes and contribute to depression or other mental disorders in adulthood is not well understood.
"Whilst these results obviously need to be replicated, they provide a mechanism by which experiences early in life can have an effect on behaviour later in adulthood." Dr Jonathan Mill
That's quite a discovery they made. It is very encouraging to hear that the damage may be reversible.
I knew it changed the patterns in the brain, but they found it made genetic changes. There have been other studies that show our experiences in life make genetic changes. Kind of support the theory of evolution, huh?
More than that, we need to adjust our thinking about people's ability to "just get over it." If their genetics and their brain is changed, they can't. They can learn to cope with it, but not "just get over it."
My questions have to do with passing the changed genetics on to children. Do the children end up with the same reactions to relationships and stress?
I'm curious about that as well. It seems logical that if your genes have been altered, you would be potentially passing on the altered gene to your offspring.
Exactly, so what effects does it have on future generations?
Sure is a call to stop abuse, isn't it?
Yes, it is. This is a case where no matter how well you nurture, there is something in nature that causes a person not to respond well to stress. We can't undo what's been done, but we can make people more aware that they are permanently altering their childrens' genetic makeup and that's no joke.
Well said.
I was the victim of child abuse. My mother -- who was my abuser -- was abused by her mother too. I've often wondered how far back it goes on my maternal line. I've thought of it as a learned pattern and counted myself as fortunate to have been born into a generation that has free access to knowledge about how to change the dysfunctional patterns.
Now I have to wonder how much of it is learned dysfunctional patterns and how much is changed genetics.
Of course, there's even more dysfunctional patterns in our society, like the abuse of women by men and the abuse of girls by boys. The macro and the micro are thoroughly intertwined.
Women are trying to throw off those patterns of abuse. Could that be why we seem to be becoming a more violent society (as compared to when I was young)? Could the need to keep the dysfunction going provoke this violence? If so, then is it learned or genetic?
As a feminist, I was hoping we'd have made more progress by now. Perhaps this helps explain why we haven't.
Interesting things to ruminate over.
I blame the bible for child abuse, spiritual abuse and wife batterings. The commands of using a "rod" on your child breaks the spirit of a child and leads to post traumatic stress disorder. I blogged about this today at http://christianfeminism-olderandwiser.blogspot.com
I think spanking/hitting/beating all justified and taught by the bible have led to the violent culture america has become.
Interesting article! May I clip it to Nurses on the Vine and Healthcare Workers on the Vine?
Sure. You should always feel free to clip my articles to relevant groups.
Did you see this seed. It's the opposite side of the coin:
