POPSchild abuse & silent witnesses Child abuse 'impacts stress gene' Child abuse has long-lasting effects 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. It affects the production of a receptor known to be involved in stress responses, the researchers said. 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. 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 But exactly how environmental factors interact with genes and contribute to depression or other mental disorders in adulthood is not well understood.

POPSFirst 'placebo gene' discovered 
To see if there were genetic differences between responders and non-responders, Furmark screened them for a variant of the gene for tryptophan hydroxylase-2, which makes the brain chemical, serotonin. Previous studies suggested that people with two copies of a particular "G" variant are less anxious in standard "fear" tests. Sure enough 8 of the 10 responders had two copies, while none of the non-responders did (Journal of Neuroscience (DOI: 10.1523/JNEUROSCI.2534-08.2008). Furmark believes the effect of the gene may extend to other conditions where the amygdala is involved, such as phobias, pain disorders and even depression. However, he cautions that only further studies will reveal whether the gene influences the placebo effect more generally. Echoing Furmark's caution is Fabrizio Benedetti of the University of Turin, Italy. "We know that there's not a single placebo effect but many." Some may work through genetics, he adds, others through the expectation of a reward.
