Dopamine plays a key role in biochemical hypotheses of schizophrenia.

There is an elevated risk of schizophrenia for individuals with a biological relative who suffers from the disorder, and the risk rates increase as a function of the genetic closeness of the relationship. For example, it has been estimated that children of schizophrenia patients have a 9 to 15 % likelihood of developing the illness, siblings of patients have an 8 to 14% likelihood, and cousins have a 2 to 6% likelihood of being diagnosed with schizophrenia. Given the general population rate of approximately 1%, relatives of patients are at statistically increased risk. It must be noted, however, that relatives share common experiences as well as common genes. Therefore, examinations of the prevalence of schizophrenia in the relatives of patients cannot elucidate the relative contributions of environmental and genetic factors.

Biochemical hypotheses of schizophrenia

All mental health professionals are trained in certain of diagnosis and treatment. They come to believe, for example, that depression is caused by faulty thinking, is caused by lack of serotonin, or is caused by repressed trauma or abuse.

This would explain why schizophrenia symptoms often first appear during the teen years.

There is more regurgitated research out there than anything truly novel or a real break through. It's possible that the media did not adequately research this area, which is quite surprising for CNN, but it could be a false reporting as well. Don't always trust the internet. In the realm of schizophrenia, the number of studies that are ground breaking, even getting to the point of advanced treatment, both for the positive and negative symptoms of the illness, may number a handful since the inception of treatment for the illness.

Patrick McCann, at the University of Oklahoma, has developed a diagnostic breath test that uses lasers to measure the amount of carbon disulphide in breath of children. Carbon disulphide is known to be at higher levels of in the breath of people with schizophrenia – even in infants. This allows him to make diagnoses decades before symptoms occur.

The schizophrenias plague about one percent of the world’s population. According to the National Institute of Mental Health, more than two million Americans are affected by some form of schizophrenia. This array of illnesses can severely impair a person's ability to manage emotions, interact with others, and think clearly. Symptoms include hallucinations, delusions, disordered thinking, and social withdrawal.

Bloodletting has been a treatment for this illness for centuries and is still the treatment of choice. Another treatment is chelation therapy. We now know that lowering iron is not only useful for hemochromatosis, but may actually be beneficial to the immune system. Infections need iron to survive. When a pathogen enters the body, the immune system blocks the infection’s access to the iron store in the system to prevent its proliferation. The human body contains many natural chelators. For example, mother’s milk contains a substance called , a protein that prevents bacteria from absorbing iron.

Schizophrenia: An Update of the Selenium Deficiency Hypothesis

is the likelihood that a certain gene will result in a specific disease. In 2006, researcher Roger Webb, at the University of Manchester in England, showed that the risk of fatal birth defects is higher in the children of parents who have been hospitalized for mood disorders. There is even more risk is associated with maternal schizophrenia. Moreover, children of mothers who had previously been admitted to a hospital for any type of psychiatric diagnosis had significantly higher risk of death from birth through early adulthood. In addition, the relative risks associated with the mother’s illness varied significantly by the child’s age and were generally greatest in the first year of life, during the neonatal (early and late) and post-neonatal periods. The risk of infant death among children with two mentally ill parents was significantly higher than that associated with having only one affected parent. Families with fathers or mothers who have a history of psychiatric hospitalizations also double the risk of sudden infant death syndrome (SIDS) compared with the general population. If both parents were hospitalized, the risk of SIDS was increased by almost seven-fold. There is evidence that SIDS may be in part caused by abnormalities of serotonin in the brainstem.
