>>40328270Granted that autism is a neurological condition where the brain is wired quite differently than a normal brain, it'd be rather impossible to completely rewire the neural network within the brain to technically get rid of the autism. At least, not without causing some serious damage if not straight up killing you.
As for curing mental illnesses such as depression, schizophrenia, etc.
I don't think they can cure it as much as they can soothe and suppress the effects or brainwash the person to keep them in a constant state where they're not suffering from it.
