What could be some possible genetic and non-genetic caused of Shannon's schizophrenia?
Shannon's schizophrenia could have genetic causes, such as a family history of the disorder, which suggests a hereditary component involving multiple genes that influence brain chemistry and functioning. Non-genetic factors might include prenatal exposure to infections or malnutrition, early childhood trauma, and psychosocial stressors, which can contribute to the development of the disorder. Additionally, environmental factors like substance abuse or significant life stressors may trigger or exacerbate symptoms in genetically predisposed individuals.
What else can I help you with?
Is schizophrenia autosomal recessive or dominant?
Schizophrenia is only partially genetic, and therefore is neither recessive nor dominant.
If a 30 year old has schizophrenia could the mother have it as well?
Yes. Schizophrenia is partly genetic, meaning that if you have a relative with schizophrenia you are likely to also have schizophrenia. About 1/10 of people with a relative with schizophrenia develop schizophrenia, compared to 1/100 people without a relative with schizophrenia.
How likely is schizophrenia hereditary?
Schizophrenia is partly genetic- one out of ten people who have at least one schizophrenic relative also have schizophrenia (compared to one out of one hundred people in general). About one out of two people whose identical twins have schizophrenia also have schizophrenia. However, schizophrenia is not completely genetic. If schizophrenia was completely genetic, everyone who had an identical twin with schizophrenia would also have schizophrenia. This is not the case. Like I said before, about 50% of people whose identical twins have schizophrenia also have schizophrenia. There are environmental as well as genetic factors to schizophrenia.
Are gentic abnormalties suspected causes in alzheimers and schizophrenia?
Genetic abnormalities
How does psychosis in schizophrenia happen?
Psychosis in schizophrenia and perhaps schizophreniform disorder appears to be related to abnormalities in the structure and chemistry of the brain, and appears to have strong genetic links
Can in vitro fertilization be used as a method to ensure that your child won't develop schizophrenia?
The short answer is "no". The long answer: While schizophrenia has a significant genetic component, there are other factors which are involved in the development of schizophrenia in later life, including brain injury due to lack of oxygen at birth, certain infections ocurring while in the womb, traumatic and stressful events over the course of life, and use of certain drugs, especially during adolescence. Furthermore, the genetic basis for schizophrenia is complex, and so far, not well understood. There are multible genes, mutations in which are known to be related to an increased risk of developing schizophrenia later, and likely, there are other, so far unknown genes which may contribute to this risk. The way in which the products of these genes interact with one another, and the effect the environment has on the expression of these genes is not fully understood. So even if it was possible (which theoretically, it is) to screen an embryo for specific genetic abnormalities linked with schizophrenia (for example, if a parent had a known mutation linked with schizophrenia), it would be impossible to be sure that no other genetic risks had been passed down, making the risks of such a procedure outweigh the potential benefits. At least until the genetic basis of schizophrenia is more fully understood. Even if we had a 100% understanding of the genetic basis of schizophrneia, embryo selection would not provide protection against the other (non-genetic) risk factors mentioned above, though it may reduce the likelyhood that exposure to these would produce schizophrenia. Hope this answers your question.
What is the difference in the expression of schizophrenia in identical twins attributed to?
The difference in the expression of schizophrenia in identical twins is attributed to a combination of genetic and environmental factors. While identical twins share the same genetic makeup, environmental influences such as stress, trauma, or drug use can lead to differences in the onset and severity of schizophrenia symptoms between twins.
Is it possible for a schizophrenic to pass his illness to his children?
Schizophrenia does have a genetic component - so risk of schizophrenia in close relatives of a schizophrenic patient are increased. This does not mean that all close relatives will definitely have the disease, but only that they are more likely to have it than non-relatives. Environmental and social stressors may increase this risk.
What have psychologists learned about schizophrenia by combining the results of twins adoption and family studies?
They have learned that schizophrenia has a strong genetic component, but that there are also other factors than genetics involved.
What makes genetic engineering possible is?
what made genetic engineering possible
If a 30 year old has paranoid schizophrenia could the mother have it as well?
There is a fairly strong genetic component to schizophrenia, but a mother cannot inherit it from her son. He, however, could have inherited some of the tendencies from her.
Is a diagnosed schizophrenic mother capable of taking care of her children?
It depends on how severely impaired the mother is. If she is only mildly affected by schizophrenia, then she may be able to take care of her children- for example, if she has infrequent hallucinations or magical thinking but no delusions, and few negative symptoms. However, if she has more severe symptoms, especially delusions relating to her children, then she may not be able to take care of her children.
