What are the main reasons for Schizophrenia?

I think that the main ones are...
frontal lobes, hippocampus, and temporal lobe deficiencies
Inhibits the function of dopamine in the molimbic pathway of brain-phenothaizines
Serotonin function in the brain also affected
Low levels of Glutamate Receptors
NMDA glutamate receptor-specifically????
Ventricular enlargement
Gene COMT is present in many people with it


Are these accurate and can you elaborate on this please? I'm very confused...

Thanks

There can be many reasons for schizophrenic-like symptoms; including, the intake of certain dugs (which in effect can lift the so-called veil of the senses), or the parasite called Toxoplasma gondii, which is relatively common and infects the brain (which often results in a false diagnosis of schizophrenia).

That said, there is only one cause of true schizophrenia - a spirit (ghost). This is easily given away when one analyzes one of the mannerisms of those with schizophrenia - their hand waving. In this mannerism, the individual either waves a hand over their head or makes a hair brushing action with their hand in an effort to either feel or wipe away the feeling of the accompanying spirit. When one sees the art depicting the saints and their halos, one is viewing a very similar set of circumstances. Those halos are the artistic renderings of spirits (the Holy Spirit). These spirits are about the head for logical reasons. The hand waving mannerisms is in effect annunciating this entities presence.

What are the reasons or what are the symptoms? The symptoms are well documented and can be found on various web sites (follow the link below). The reasons that people suffer from almost all mental disorders are educated guesses; science doesn't understand the brain well enough to give exact answers.

With that little disclaimer:
"The causes of schizophrenia have been the subject of much debate over many decades with various factors proposed and discounted. Studies suggest that genetics, prenatal development, early environment, neurobiology and psychological and social processes are important contributory factors. Current psychiatric research into the development of the disorder is often based on a developmental model. In the absence of a confirmed specific pathology underlying the diagnosis, some question the legitimacy of schizophrenia's status as a disease. Furthermore, some propose that the perceptions and feelings involved are meaningful and do not necessarily involve impairment.

Although no common cause of schizophrenia has been identified in all individuals diagnosed with the condition, currently most researchers and clinicians believe it results from a combination of both brain vulnerabilities (either inherited or acquired) and life events. This widely-adopted approach is known as the 'stress-vulnerability' model, and much scientific debate now focuses on how much each of these factors contributes to the development and maintenance of schizophrenia. Schizophrenia is most commonly first diagnosed during late adolescence or early adulthood suggesting it is often the end process of childhood and adolescent development. There is on average a somewhat earlier onset for men than women, with the possible influence of the female hormone estrogen being one hypothesis and sociocultural influences another."

In other words; we don't know. The answer seems to be both a nature/nurture issue.

i heard it was too much dopamine in the brain...?
