IAAN

IAAN or Idiopathic Adolescent Acute Neurodegeneration is a fatal disease that swept through America and killed 98 percent of America's youth. It was formally named Everhart's disease, after Michael Everhart, the first victim to fall into the clasp of IAAN. It is known to affect children around the ages of puberty (8-14).

Symptoms
There weren't certain symptoms to IAAN, except sudden death, where the vicitm gain hyperfocus and then falls to the ground dead. Survivors recieved psionic abilities, which were referred to as symptoms from PSFs.

Cause
The Cause of IAAN was Agent Ambrosia, where the US government entered a certain chemical into the water and food supplies in order to prevent any terrorist attacks. Pregnant women, men, and children were all tested on for results of this chemical, but when nothing came up they dropped the case. But the the children born after the chemical release were the ones affected. The pregnant mothers consumed the water, yet the children were the ones affected. The reason that so many died was because the pregnant mothers consumed too much of the chemical, and their child couldn't take it. The cause for different psionic abilities was genes.
