The connection is not surprising, but it raises a crucial scientific question: Does the abuse cause biological changes that may increase the risk for these problems?
Over the past decade or so, researchers at McGill University in Montreal, led by Michael Meaney, have shown that affectionate mothering alters the expression of genes in animals, allowing them to dampen their physiological response to stress. These biological buffers are then passed on to the next generation: rodents and nonhuman primates biologically primed to handle stress tend to be more nurturing to their own offspring, Dr. Meaney and other researchers have found.
