People who have a relative with schizophrenia have a greater risk of developing the disorder than the general population. For example, if you have an identical twin with schizophrenia, your chance of having schizophrenia is 50% in contrast to the 1% chance for the public at large. Adoption studies have shown that biological relatives have an increased risk for schizophrenia whereas adoptive relatives have no increased risk. Such studies clearly point to the contribution of a genetic component in the development of schizophrenia. Nongenetic factors can also influence the development of schizophrenia, as evidenced by the fact that, even in people with identical genes (i.e., monozygotic twins), only in about 50% of the cases are both twins ill. more

Unfortunately yes it is believed to be hereditary: Estimates of the heritability of schizophrenia tend to vary owing to the difficulty of separating the effects of genetics and the environment although twin studies have suggested a high level of heritability.[50] It has been suggested that schizophrenia is a condition of complex inheritance, with several genes possibly interacting to generate risk for schizophrenia or the separate components that can co-occur leading to a diagnosis.[51] These genes appear to be non-specific, in that they may raise the risk of developing other psychiatric disorders such as bipolar disorder.[52] However, recent metaanalyses of linkage studies have produced conflicting findings.[53] Larger-scale, thus more sensitive genome-wide association studies are being conducted.[54] Schizophrenia has also been associated with rare deletions or duplications of tiny DNA sequences (known as copy number variants) disproportionately occurring within genes involved in ... more

The symptoms of schizophrenia appear to be hereditary. In reality schizophrenia is not a disorder but merely a list of symptoms that are of a supernatural origin. Those with schizophrenia are some of the saints found in the scriptures. It is because righteous behavior is often taught from parents to offspring that symptoms of such occur in families. In other words, saints beget saints. When you look at art that depicts the saints, you are looking at a phenomena similar to our own. The halo in art is the so-called Holly Spirit. It is this being that you feel "hovering over" you. In effect, this spirit is your halo. You grandfather apparently also had such a spirit. Do not be fearful as your situation is a blessing. more

There is no "gene" for schizophrenia. It's not like having blue eyes. Having a family member with it does increase your chances slightly, but not enough that I'd worry. And with a relative as distant as an uncle, I'd be even less worried. Your risk of getting it is probably about the universal average - 1%. Schizophrenia, like all mental illness, is a complicated mixture of environment and family history. more

I would like to be kinder about it but yes, schizophrenia is hereditary. It usually manifests itself during the late teens into the early to mid twenties. more

There is still some disagreement about the degree that heredity plays in the development of schizophrenia, but there is no question that at least a predisposition to the disorder can be inherited. more

Schizophrenia does run in families. It is possible to develop it, but we aren't really sure what causes it. Clearly, genetics is just one factor in whether someone will develop the disorder. You may want to seek help from a qualified mental health professional just in case. If you don't like the results you get, don't be afraid to see someone else. Good luck to you! more

The last time I checked, about 3 years ago, the chances of having kids with schizophrenia were 1% if it's not in your family and 2% if it's in your family. It's really hard to tell, they don't know much about it yet. About your symptoms, it could be real or it could be the fear of having a mental illness playing tricks on you. You should tell a doctor. more

yes schizophrenia is hereditary., but usually skips a generation. males can be schizophrenic as young as 16 and quite often around 18 to 24. early detection is a good idea. perhaps it would be a good idea to educate yourself about schizophrenia so you may be able to understand your father better, and to help you. today there are a lot of better medications, than when your father was diagnosed. and people today can live a fairly normal life with the proper treatment. schizophrenia also can be severe or mild. try not to worry too much if you get it, as you may never get it at all don"t be afraid if you see some of symptoms of schizophrenia in yourself we all have some of these symptoms but it depends on degree or the severity. you could check with your fathers doctor too that might put u at ease. more

It is hereditary but it is unlikely that you would get it. Possibly his children but not you. So don't worry about it anymore. There really aren't any actions or anything that can be done to prevent it unfortunately. more
