#3 Grisi Siknis
“Crazy sickness” is how this disorder is defined – literally! Gris Siknis is a high contagious condition that is rare but mostly occurs among the people of Nicaragua.
The sufferer goes into a state of hysteria! An episode starts with headaches, nausea, dizziness, anxiety, and leading up to a build-up of irritational fear and anger.
While in a state of hysteria, they engage in weird behaviors like arguing with unseen people, talking in tongues, and trying to perform supernatural acts!
If hurt during a struggle, they feel no pain. Once the episode is over, they lose consciousness and run away.
Some may not even remember this incident due to absolute amnesia – as if nothing happened!
