Stresas karinių konfliktų metu susijęs su galvos smegenų pakitimais.

Nacionalinė Medikų Asociacija paskelbė 2012-09-05 04:08 Olandų mokslininkai teigia, kad papraščiausia keturių mėnesių trukmės karinė tarnyba Afganistane gali sukelti galvos smegenų pakitimus ir sumažėjusį dėmesį. Šie smegenų pakitimai gali atsistatyti savaime po pusantrų metų po tarnybos. Plačiau...

The Stress of War Can Cause Changes in a Soldier’s Brain

Dutch scientists have reported that, “A single four-month deployment to Afghanistan is associated with brain changes and diminished attention,” says Science News. “Most changes went away a year and a half after returning from combat, suggesting that the brain can largely heal itself.”

The study involved researchers from the University of Amsterdam conducting “brain scans while the soldiers performed a lab test that required them to hold several numbers in their memory simultaneously.” They didn’t find any differences between soldiers who were about to be deployed for the first time and those who were still in training. But after the soldiers experienced combat, it was a different story.

Science News notes that, “After their return, the soldiers went back to the lab for another round ofbrain scans. During the memory task, the post-deployment brain scans showed lower activity in the midbrain, a region known to be involved in working memory, compared with the brains before deployment. What’s more, midbrain tissue showed signs of damage and weaker connections with another brain region, the prefrontal cortex. Together, the midbrain and prefrontal cortex are involved in working memory and attention, among other things.”

These results aren’t surprising in light of other research that’s examined the effect of war on soldiers. In 2011, FairWarning reported that a study in The Journal of the American Medical Associationfound that, “Combat-related post-traumatic stress disorder is more likely to have long-lasting effects on soldiers than concussions or ‘mild traumatic’ brain injuries . . . The researchers cited symptoms such as diminished concentration and memory, along with irritability and problems with balance.”

On the flip side, a 2009 article in USA Today explored the work of Richard Tedeschi, an expert in post-traumatic growth at the University of North Carolina at Charlotte, who was collaborating on a project with the Army. “Even though he calls the initiative ‘uncharted territory,' Tedeschi says research indicates that soldiers have found value in their combat experiences. If informed about potential for post-traumatic growth beginning in basic training, he says, soldiers might not automatically assume that the combat experience produces PTSD and you're kind of doomed . . . At the same time, as this trauma separates them from other people, it also allows them to maybe see themselves as more human than they ever were before, have a closer connection with what it means to be a human being.’"


Tedeschi’s notion that soldiers should learn about post-traumatic growth during training is in sync with advice offered by HealthGuidance that states, “what we need to ask ourselves is how we can protect them from mental trauma before they are even sent to fight, as opposed to treating their symptoms once the deep psychological damage has already been done.”

The Science News report has one suggestion: “Along with the finding that the brain can reverse the changes given enough time to recover, may mean that soldiers ought to have longer periods of time between deployments . . . Multiple stressful deployments in quick succession may prevent recovery.”
