Stress early in life might alter genes

Stress and trauma early in life may have such a significant impact it could change genes and cause behavior problems later on. Scientists studied mice that had been separated from their mothers for several hours a day. That sense of abandonment produced hormones that changed their genes, affecting behavior through their lives.

While this work in the journal Nature Neuroscience was carried out on mice, researchers are also investigating how childhood trauma in humans can lead to problems such as depression.
