Patient's question:
Patient Age: A friend is about to get married, but suddenly finds out that his girlfriend's mother has a mental illness.Doctor's answer:
A large amount of genetic research on schizophrenia can only indicate that the occurrence of schizophrenia is related to genetics, but it cannot conclusively determine that schizophrenia is a genetic disease. From pedigree studies of schizophrenia, it has been found that the incidence rate of schizophrenia among relatives of patients is 6.2 times higher than that of the general population. When a schizophrenia patient marries a healthy person, the probability of their children developing schizophrenia is 16.4%. If both partners are schizophrenia patients, the probability of their children developing schizophrenia is 39.2%. Therefore, it appears that schizophrenia indeed has a certain genetic tendency, but not all children of schizophrenia patients will develop the disease.
