For nearly two decades Sweden has been battling a mysterious illness, called Resignation Syndrome which affects only the children of asylum-seekers, who withdraw completely, ceasing to walk or talk, or open their eyes. As per the health professionals treating these children, trauma is what causes them to withdraw from the world. The children who are most vulnerable are those who have witnessed extreme violence - often against their parents - or whose families have fled a deeply insecure environment. While the researchers have not been able to find a solid explanation for the disease, the most plausible explanation is that there are some sort of socio-cultural factors that are necessary in order for this condition to develop, a certain way of reacting or responding to traumatic events seems to be legitimised in a certain context. Over the last decade, the number of children reported to be suffering from Resignation Syndrome has decreased. Sweden's National Board of Health recently stated there were 169 cases in 2015 and 2016. The recovery of such children depends on them feeling secure. In most cases, children do recover.
