Early signs, diagnosis and therapeutics of the prodromal phase of schizophrenia and related psychotic disorders Risk factors such as age, family history of psychosis and symptom scores were combined in a multifactorial index of risk [50,51]. From this work came the creation of the CAARMS, which takes into account the intensity, frequency and duration of emerging positive symptoms, as well as declines in functioning.

Why did John Nash have schizophrenia? Scientists think interactions between genes and the environment are necessary for schizophrenia to develop. Many environmental factors may be involved, such as exposure to viruses or malnutrition before birth, problems during birth, and other not yet known psychosocial factors.

Hyperhomocysteinemia There is also evidence that elevated homocysteine levels and low levels of vitamin B6 and B12 are risk factors for mild cognitive impairment and dementia. Oxidative stress induced by homocysteine may also play a role in schizophrenia.

Schizophrenia People who have second-degree relatives (aunts, uncles, grandparents, or cousins) with the disease also develop schizophrenia more often than the general population. The risk is highest for an identical twin of a person with schizophrenia. He or she has a 40 to 65 percent chance of developing the disorder.oices are the most common type of hallucination in schizophrenia. Many people with the disorder hear voices. The voices may talk to the person about his or her behavior, order the person to do things, or warn the person of danger.

So, the diathesis-stress model holds that schizophrenia is the consequence of a stress-activated diathesis or predisposition.

Schizophrenia  In-Depth Report Schizophrenia can have a devastating impact on patients and their families. Patients with schizophrenia have increased risk for self-destructive behaviors and suicide. The antipsychotic drugs used to treat schizophrenia can have severe side effects, including increased risk of obesity and diabetes.ost drugs that treat schizophrenia work by blocking receptors of the brain chemical (neurotransmitter) dopamine. Dopamine is thought to play a major role in psychotic symptoms. Although the drugs used to treat schizophrenia have important benefits, they can also cause many side effects.

- Twin studies have shown that it is partially hereditary, with a concordance rate of 40% in monozygotic twins, and a risk increase to 6.5% in people with an affected first degree relative. Schizophrenia is 1.4 times more common in men than women.The age of onset is typically late adolescence or early adulthood. In women, it tends to begin later in life and in a milder form compared to men.

Some studies indicate an imbalance between the two may be the basis of the problem. Others have found a change in the body's sensitivity to the neurotransmitters is part of the cause of schizophrenia.
