Piblokto

Piblokto, Pibloktoq or arctic hysteria is a condition exclusively appearing in Inuit societies living within the arctic circle. Appearing most prevalently in winter, it is considered to be a form of a culture-specific disorder.

Symptoms can include intense "hysteria" (screaming, uncontrolled wild behavior), depression, coprophagia, insensitivity to extreme cold and more. This condition is most often seen in dogs and Eskimo women.
