Once the LFA are cured of autism, they will still be mentally ret*d.
So they have to be cured of mental retardation too.
Some of them also have major problems like epilepsy or various genetic disorders that caused all their brain problems, so that will have to cured.
If there is a specific genetic disorder, it would be best to target that for a cure.
