The apathetic children began showing up in Swedish emergency rooms in the early two-thousands. Their parents were convinced that they were dying. Of what, they didn’t know; they worried about cholera or some unknown plague. Soon patients with the condition filled all the beds in Stockholm’s only psychiatric inpatient unit for children, at Karolinska University Hospital. Göran Bodegård, the director of the unit, told me that he felt claustrophobic when he entered the rooms. “An atmosphere of Michelangelo’s ‘Pietà’ lingered around the child,” he said. The blinds were drawn, and the lights were off. The mothers whispered, rarely spoke to their sick children, and stared into the darkness.
