A 52-year-old man was minutes from his own front door when the orange cones went up. Every street he tried was closed. When a truck pulled up and workers began sealing off the last open route, he ran a red light, accelerated through the intersection, and started shouting at the man laying the cones.
That episode is now the first medically documented case of what its author calls "Montreal syndrome," described in a case report in the World Journal of Psychiatry.
