My girlfriend may have Schizophrenia in her genes. Her father shows no signs and never has, but her aunt and uncle on his side of the family both suffer from Schizophrenia. The only other family member she knows of who had the disease was her great uncle on her fathers side. She has never had any signs of the disease and her brother and sister are also perfectly normal. First question, can you validate the statement we have heard that Schizophrenia tends to skip generations? This would put her children at risk. Second question, what are the chances or her developing the disease later in life if she has never had a problem in 25 years? Third question, is it possible to screen her genes for the potential that her children will develop Schizophrenia before she gets pregnant? Having children with the disease is a serious and legitimate concern for her as well as her brother and sister. Any information you can provide would be greatly appreciated. Thanks.

Schizophrenia Answer A28
ONE of the risk-factors for schizophrenia is that someone in the family has developed the disease. Many other factors than genetic factors are involved in its pathogenesis (traumas, infections, social environment). Having a genetic risk-factor for schizophrenia, however, does not necessarily mean that your girlfriend or her progeny will develop the disease automatically. Genetically, a fetus must inherit the “schizophrenic” genes from its parent(s). This may/may not happen because a fetus receives only half of the father’s and half of the mother’s genes (23 chromosomes each). If “schizophrenic” genes are not among the randomly chosen halves, they won’t be inherited. If “schizophrenic” genes are among those that form the fetus, they will be inherited.





It is important to note that sometimes “schizophrenic” genes are not inherited at all. Instead, genes can become mutated from normal genes during the early stages of embryogenesis.





Persons who carry “schizophrenic” genes don’t normally have the illness automatically, but only a predisposition to have it. Schizophrenia is not a simple, inheritable illness where only a presence of “schizophrenic” genes is enough for developing the disease. That’s why there are a lot of patients with schizophrenia who don’t have any relatives who have also been diagnosed with the disease... and a lot of people who don’t develop schizophrenia although they do have relatives with schizophrenia.





About your questions; I can’t validate the statement about “skipping generations” because I couldn’t find any reliable data to confirm this. Statistically, there are less chance that people over 25 will develop schizophrenia. Even if you screen her genes and find “schizophrenic” genes, there are no guarantees that she or her children will/won’t develop schizophrenia.

Hello.. Firstly I have not done anything like this before but felt lately that I needed to ask..

Most of my life I have been hearing people say something that they claim they have never said.. but recently this has gotten worse..an example of this is when my boyfriends bother came up to me and told me that I wouldnt be going to the hens party however according to him and my boyfriend who was there at the time this never happend. I have also been seeing black shadows of people but only at the corner of my eye.. when they catch my attention and I try to catch it.. it's gone.. I'm also forgetting things more often...

Futher to this a little earlier last year my sister was admitted for Schizophrenia (which they said was caused by stress) It was the first time for her at 27 and the last for a year now.. Anyway I was just worried that I may start to be having the same issue?

There are some well know percentages. 1% of the general population gets it. 10% of people with a parent or sibling that have it will get it themselves. obviously there is a very high correlation for identical twins if one has it.
But genetics is not enough.
1. Diet plays a role so get her to take a schizophrenia supplement (SBX) this may help prevent the disease, and eat well.
2. if there have been few traumatic events in her life and she is over 25 then this also will help but my wife was triggered by child birth and an international move when she was about 30.
