Is Shizophrenia hereditary?if a girl`s sister has it,does the sister,whose normal,when gets married,?

Question

transfer it to her children?

Answer 1

The cause of schizophrenia is not definitely known. Hereditary aspects certainly are a factor of importance, as twin-studies have shown. First degree relatives have a higher risk of acquiring the disorder. The notion that rearing styles or upbringing causes shizophrenia has been entirely abandoned. Though causes per se are not known, those afflicted by the disease are thought to have a congenital vulnerability for decompensating under stressful circumstances. Indeed, stress may precipitate the first onset of the psychosis or cause a relapse. In most of the cases Shizophrenia is proved to be hereditary and it may affect the borther or sister after a gap of period-

Answer 2

It is, presumably, a recessive trait.

That means you have a 1 in 4 chance of not having inherited it, since both of your parents would have to have had the gene.

Now, if you are talking about schizophrenia - it is belived to have a genetic component. There is a 50% chance you can pass the affected gene onto your children, but you would have to become impregnated by a man also carrying the gene for it to become a concern. In this case, your kids will have the same 1/2/1 ratios you and your sister had when you were born.

By the way...this is the *cancer* forum, schizophrenia sould be under mental diseases/disorders.

Answer 3

Schizophrenia does have a tendency to run in families. Family members of someone with Schizophrenia tend to show a greater vulnerability to a wide range of mental illness or instability, however, this is due in no small part to simply having to deal with the problem of having one in the family.
There may be some biological predisposition to schizophrenia, but that doesn't necessarily mean the disorder itself is genetic or hereditary. Even when it seem to run in families, it's not clear -- at least, to psychologists, how much is genetically based and how much is passed down behaviorally through family dysfunction.
I would say that, as long as the children are brought up in an emotionally stable environment, and checked on a routine basis for early signs of problems, there isn't much reason to believe that the kids would have a much higher risk.

Answer 4

It's possible. And yes, schizophrenia is a genetic characteristic. If the sister who is asymptomatic reproduces with someone who does not have a familial history of the disorder there is little probability that her offspring will inherit the disorder. My suggestion is for her to talk with a geneticist who will give her more detailed information.

Answer 5

Yes it is heriditary and can show up anywhere in the family. You can never tell where it might strick next. You do have a greater chance when your parents carry the gene of passing it to your kids, but some people come out fine.

Answer 6

1 in 100 people suffer from schizophrenia.
1 in 10 people with a first degree relative suffer from schizophrenia.
The sister's children will be 2nd degree relatives, with a risk factor somewhere between the two.
Environment can also be a factor.

Answer 7

Mental illness such as schizophrenia can be hereditary, but that doesn't mean that a child of a schizophrenic will for sure get it too. It is possible, though.

Answer 8

There is always a chance.
However in my family. My parents have so many mental illnesses. Yet I'm okay.
My dad has anxiety, and schizo effective.
My mom has schizo effective. But is slow.
I have nothing. Although I have a tic.

My fiances grandmother and great grandmother were shizo-effective. His aunts, uncles, mom and dad were all drug-addicts. He has nothing but ADHD.

Answer 9

It is a possibility, but it isn't a given. My sister had schizophrenia. I adopted my daughter.

Answer 10

Yes it is. It is carried in the genes. It can show up anywhere in the family.
