How do u get Schizophrenia?

I did a research paper on schizophrenia for my college psychology lab and I found that it is definately known and not simply implicated that less than 2% of those who have schizophrenia have a genetic link. The methods for coming up with 50% are flawed. For 98% of those who have been diagnosed there is no known relative who has schizophrenia. The 50% comes from twin studies which shows the rate among twins but not among the general population. If schizophrenia was purely genetic then the indentical twin rate would be astronomically higher than 50%.

The following is about bipolar, but is also true of schizophrenia.

A first-degree relative is 8 to 18 times more likely to develop a disorder. If both parents have bipolar disorder there is a 50 - 75% chance of their child having the disorder. There is a 25% chance that the child of a bipolar parent and non-bipolar parent will develop the disorder.

Those odds are daunting enough without considering environmental influences. These influences can be obvious: family relations, abuse (physical and mental), physical illnesses, stress and traumatic experiences. The influences may be self-imposed: abuse of drugs, both illegal, prescription, and over the counter, a poor diet, affecting brain and body chemistry in a negative way, alcohol and tobacco use and abuse, and other types of self-abuse. There are other culprits, which include allergens, exposure to toxic chemicals, heavy metals, noise, carbon monoxide and non-specified or general pollution.

Keep in mind that this chance depends on if the parents have the inheritable type of schizophrenia and not the purely environmentally caused type such as drug abuse. What may be inherited through socialization is a parents vices which led to getting schizophrenia such as drug abuse, alcohol abuse, or cigarette smoking, or child abuse, etc. it is reported that 75% - 90% of schizophrenics smoke cigarettes and these bright guys who do research have yet to say that smoking is a major cause of schizophrenia...duh...how obvious can you get? That's higher than the concordance rate of identical twins and comes very close to counting as a statistical rarity which implies causality.

Genetically.

You don't get it like a cold. It's a brain abnormality that occurs generally about the college age. It is hereditary.

Schizophrenia is caused by a chemical imbalance in the brain. You can inherit it from your parents, siblings or other relatives, although not always. Schizophrenia research is now proving that it can be brought on as a result of a virus, causing changes in the brain.

Schizophrenia is a brain disorder. It is genetic. It results from the way one's brain chemistry works. You have to meet the criteria set forth in the DSM-IV-TR. Onset typically occurs in late teens to early 20's. It is more common in men.

Studies have indicated that about 50% of the cause of schizophrenia is genetic. The remaining 50% is caused by situational factors.

Development is thought to follow the "diathesis-stress" model of disease development. There is a diathesis - some state that makes a person more prone to developing the condition than they otherwise would be. This is the genetic component.

During a person's life, if they have that diathesis, they might be exposed to the right types of stressors that cause that lurking disorder to come out and begin causing problems.

Substantial research seems to indicate that we don't know what many of the relevant stressors are for the development of schizophrenia. A substantial one though, is what has been termed "expressed emotion".

Expressed Emotion, or EE, is defined in this context as hostile or intimidating emotional expressions that the person RECEIVES. If a person with a propensity for schizophrenia is raised in an abusive or neglectful home, they may well be exposed to enough EE to bring out the schizophrenia. Not that abuse or neglect is necessary, it's just one of many ways to get sick.

Also, schizophrenia tends to appear in early adulthood. It very rarely appears before the age of 16 and very rarely appears after 35.
