Hurtful Words Damage the Brain

We know it breaks our heart but now neuroscience is telling us that it "breaks" our brain too - here:

Early childhood sexual abuse, physical abuse, or even witnessing domestic violence, have been shown to cause abnormal physical changes in the brain of children, with lasting effects that predisposes the child to developing psychological disorders. This type of brain scarring is well established now by human brain imaging studies, but prior to the recent study by Martin Teicher and colleagues at Harvard Medical School, taunting and other verbal abuse experienced by middle school children from their peers was not thought to leave a structural imprint on the developing brain. But it does, according to their new study published on-line in advance of print in the American Journal of Psychiatry.

The results revealed that those individuals who reported experiencing verbal abuse from their peers during middle school years had underdeveloped connections between the left and right sides of their brain through the massive bundle of connecting fibers called the corpus callosum. Psychological tests given to all subjects in the study showed that this same group of individuals had higher levels of anxiety, depression, anger, hostility, dissociation, and drug abuse than others in the study.

Verbal abuse from peers during the middle school years had the greatest impact, presumably because this is a sensitive period when these brain connections are developing and becoming insulated with myelin. (Myelin is formed by non-neuronal cells, brain cells that are also known as "the other brain", or glia.)

The environment that children are raised in molds not only their mind, but also their brain. This is something many long suspected, but now we have scientific instruments that show us how dramatically childhood experience alters the physical structure of the brain, and how sensitive we are as children to these environmental effects. Words--verbal harassment--from peers (and, as a previous study from these researchers showed, verbal abuse from a child's parents) can cause far more than emotional harm.
