Sometimes people are malnourished. The B-vitamins are important cofactors for metabolic activity. An old/new treatment for "schizophrenia" is Vitamin B3 [0]. My girlfriend's treatment provider did a genetic test this past summer and found that she's a poor methylator. This means that she doesn't convert folic acid (synthetic Vitamin B-9) into folate very well. They've put her on prescription folate [1], and she's doing much better than when she was just double-tranquilized. I asked the biochemist about this issue, and he said that when on a good diet with folate-rich foods (liver, etc), even 'mutants' get plenty of folate.

The street pharmacy's stimulants (cocaine/meth) shred the mitochondria. These are known causes of substance-induce psychotic disorders.
People who drink heavily train their nervous system to become insulin-resistant and run on acetate (one of the breakdown products of ethanol). I think it's well-established that excess alcohol is inflammatory, which is also associated with psychosis.
So... Cute anecdote from today. I called two attorneys because I've hit a wall in my efforts to convince my girlfriend's treatment provider that she's been misdiagnosed and is not actually benefiting from the palliative maintenance medications (anti-psychotic/etc) they're still forcing her to take.
The first attorney listened to me, confirmed that it was within my legal rights to file pro-se petitions with the court, said that rural judges don't want to cause problems for their community's treatment provider, and said he couldn't help me because he'd already done some work for my girlfriend's treatment provider. He gave me the number for the second attorney.
It later occurred to me that the treatment provider certainly consulted him about my suit against them.

edit2: physical injuries and inescapable/emotional stress are drains on the body's energy-producing capacity too. My other friend's father gradually became "schizophrenic" after he broke his back falling out of a tree.
