Pervasive refusal syndrome (PRS) is a rare but severe condition, characterised by social withdrawal and a pervasive active refusal in terms of eating, mobilisation, speech and personal hygiene. PRS has been proposed as a new diagnostic entity in child and adolescent psychiatry, although the diagnostic criteria are debated. In the past 10 years there has been an increase in PRS symptoms among asylum-seeking children and adolescents in Sweden. Here, we describe five cases of PRS among asylum-seeking children and adolescents.
