Child abuse changes your brain

If you were abused, you almost certainly already believed this.

If you read the March, 2002 Scientific American article (preview here), you were more convinced.

Now, though, the extremely respectable journal Current Biology has published an article, "Heightened neural reactivity to threat in child victims of family violence," that makes the point quite clearly with some excellent work from a group of top UK scientists. (Thanks to my pal, John Lambshead, for pointing me to this story.)

For an easy to read summary of it, check out this Wired piece, "How Abuse Changes a Child's Brain." The article opens with this line:

The brains of children raised in violent families resemble the brains of soldiers exposed to combat, psychologists say.

Hell, many of my readers and Dave's already knew that. I sure did. Still, the scientific confirmation is good to have.

This bit summarizes the research:

His team compared fMRIs from abused children to those of 23 non-abused but demographically similar children from a control group. In the abused children, angry faces provoked distinct activation patterns in their anterior insula and right amygdala, parts of the brain involved in processing threat and pain. Similar patterns have been measured in soldiers who've seen combat.

The brain changes, of course, are not the only physiological adaptations to abuse (and PTSD of other sorts). As the Scientific American article and its sources made clear, key glands also change, one consequence of which is a heightened adrenaline response.

I do not mention all this to make excuses, because I don't believe any of it provides an excuse for anything I or any other abused person does. We are each responsible for our actions.

No, I'm bringing it out because I want people to understand that the cost of child abuse is high and lifelong, physical and mental, and most importantly, unacceptable.
