Domestic violence seriously affects child’s brain / Ozbiljan uticaj nasilja u porodici na mozak deteta

            It is well-known that children who suffer abuse or witness domestic violence are known to be at greater risk of anxiety and depression in later life. This time scientists wanted to know how exactly family violence affects child’s brain.
            They carried out magnetic resonance imaging brain scans on 20 London children with an average age of 12 who had been exposed to violence at home. While in the scanner, the children were shown pictures of male and female faces with sad, calm or angry expressions. Their patterns of brain activity were compared with 23 children with no history of family violence.
            The children exposed to violence responded in a distinct way to angry faces, the study found. Their brains showed heightened activation in two regions associated with threat detection.
            Previous research has shown a similar pattern in the brains of soldiers exposed to violence combat situations. The scans suggest both combat veteran soldiers and children who witness violence tune their brains to be hyper-aware of environmental danger.
            Enhanced reactivity may represent an adaptive response for these children in the short term, helping keep them out of danger. However, it may also constitute an underlying neurobiological risk factor increasing their vulnerability to later mental health problems, and particularly anxiety.
            Not every child exposed to family violence will go on to develop a mental health problem; many bounce back and lead successful lives. But it’s very important to know much more about those mechanisms that help some children become resilient.
            The report should energise clinicians and social workers to double their efforts to safeguard children from violence. By helping us understand the consequences of maltreatment the findings also offer fresh inspiration for the development of effective treatment strategies to protect children from the consequences of maltreatment.



            Dobro je poznato da su deca, koja trpe ili prisustvuju nasilju u porodici, kasnije jako podložna psihičkim poremećajima kao što su anksioznost i depresija. Ovog puta naučnici su želeli da utvrde tačno na koji način nasilje u porodici utiče na mozak deteta.
            Oni su skenirali mozak magnetnom rezonancom dvadesetoro dece iz Londona, u proseku 12 godina starim, koja potiču iz porodica sa nasiljem. Deci su davane fotografije muških i ženskih osoba sa različitim izrazima lica. Neka su bila tužna, neka smirena, a neka ljuta. Deca su posmatrala slike još dok su bila u skeneru. Onda su dobijeni rezultati upoređeni sa rezultatima dvadeset troje dece u čijim porodicama nema nasilja.  
            Deca izložena nasilju su reagovala na besna lica na veoma određen način - registrovana je pojačana aktivnost njihovih mozgova i to u onim delovima koji su zaduženi za otkrivanje opasnosti.
            Neka ranija istraživanja su pokazala sličnu reakciju mozga kod ljudi koji su učestvovali u ratu. Ovo skeniranje sugeriše da vojnici-veterani i deca-svedoci nasilja, na isti način aktiviraju delove mozga zbog opasnosti u njihovoj neposrednoj blizini.
            Pojačana aktivnost može da predstavlja kratkoročnu reakciju, instinkt za odbranu od potencijalne opasnosti. No, ona takođe može da predstavlja faktor neurobiološkog rizika koji povećava ranjivost deteta, a kasnije vodi ka mentalnim problemima, naročito anksioznosti.
            Neće svako dete kasnije da ima mentalnih problema. Mnogi će da vode normalan i uspešan život. Ali istraživanja ovog tipa su veoma važna jer uz pomoć njih možemo da saznamo više o mehanizmima koji pomažu deci da se mnogo bolje nose sa nasiljem u neposrednoj blizini.
            Ovaj izveštaj bi morao da podstakne sve koji su u lancu zaštite deteta, poput socijalnih radnika, da udvostruče svoje napore u zaštiti dece od nasilja. Pored toga što nam pojašnjava posledice nasilja u porodici, ovo istraživanje pruža i podsticaj za razvoj strategije koja bi bila efektnija u lečenju dece.

  1. It is sad that the children are the ultimate victims of these domestic violence. Growing up in such an unhealthy environment may make them traumatized for life.

  2. Children are indeed the absolute victims of domestic violence. Any kind of violence, whether it's a violence towards parents and other people , may affect the children in so many ways. Trauma is just one of the crises. In line with this, there's also a big tendency for a child to do the same thing to other people when he grows up.

  3. According to a divorce lawyer in Long Island who is also an expert in family law, domestic violence is indeed one of the many reasons why many children do the same violence in the later years. Witnessing such violence has a great impact on the way these people act. In my opinion, witnessing any kind of violence may lead a an individual to exhibit PTSD, a psychological disorder which is difficult to cure.
