The trauma of running away from persecution, war and natural disasters can leave permanent scars on an individual. A latest study has highlighted the extent of the effect such life experiences can have on refugees.

As per a study of 1.3 million people in Sweden, refugees are highly vulnerable to suffering psychotic disorders, like schizophrenia, as compared to the native residents and other migrants.

Published on Tuesday in the journal BMJ, the research said that refugees have three times more chances of experiencing schizophrenia and other psychoses than native-born Swedes.

It has also been found that refugees are also two-thirds as likely of contracting such disorders in comparison to people who have come from the same areas but due to other reasons, like economic factors.
