The Swedish 1,000-yard stare syndrome is developed when a mentally stable person is exposed to an individual with an extra chromosome for a long period until their mental mind combusts into flames. Upon this full mental death, they do a 1,000-yard stare into oblivion for 24 hours straight until they die from a lack of oxygen.
