There are a lot of causes of schizophrenia, so first I would figure out what's causing it. Here's a list:
Also, they figured out that schizophrenia is caused by too much dopamine and Parkinson's Disease is caused by not enough dopamine. So they created drugs to lower dopamine (neuoleptics like thorazine and the newer atypical drugs like risperdal and clozapine) and drugs to raise dopamine- carbidopa-levodopa. It makes sense because too little dopamine causes parkinson's disease and when someone takes too much antipsychotic drugs they get parkinsons-like-side effects.
Have you tried any of the newer drugs? Some people do amazingly well on them.
This disorder is very interesting. It causes alcoholism and mental illness and it's so simple to cure:
"A pyrrole is a chemical substance that is involved in the formation of heme, which makes blood red. Pyrroles bind with B6 and then with zinc, thus depleting these nutrients. Abnormal production of pyrroles and their appearance in the urine of psychotics was first noticed in 1958 during LSD experimentation. Approximately 15-30% of "schizophrenics" have pyroluria. (At least 10% of these also have histamine problems.)
Symptoms include sweet, fruity breath and body odor, general loss of appetite, motion sickness, problems with sugar metabolism, allergies. Mental phenomena include delusions, hallucinations, paranoia, occasional loss of contact with reality, amnesia spells, and low stress tolerance. Person has a tendency to have insight (understand they have mental problems).
The ailment, which normally strikes females, generally responds well to B6 and zinc treatment."
That was from the url above and if you google it there's a lot more info.
I believe that Iboga root or Ibogaine, made from it, would cure schitzophrenia because it resets the seratonin and dopamine recepters in the brain.
However, guess what, it is illegal here in the USA.
There are treatment centers in Mexico, Canada and other countries.
