Genetics (heredity)
Schizophrenia might run in a family which means a huge likelihood of experiencing schizophrenia might be passed on from the parents to their kids. If there is no background of schizophrenia in a family, the risk of having it is lower than 1%. Therefore, an individual’s risk increases if one of their family members or parents has a diagnosis of schizophrenia. One of the most important risk factors for schizophrenia might be genes. This disease tends to run in families. If you have a sibling, parent, or other close family member having such a condition, you might have an increased likelihood of having it as well. Therefore, researchers do not think a single gene is leading to this disorder. Instead, they doubt several combinations of genes might make someone more recognizable. Other factors, like stressors, might be required to stimulate the disorder in individuals who are at increased risk. Studies on twins might have presented that genes play a significant role but they are not the only identifying cause.
Researchers present that if each identical twin sibling has schizophrenia, the other consists of a 1 in 2 chance of forming it. This remains genuine even if the twin is separately raised. If a twin is fraternal (nonidentical) and has been examined with schizophrenia, the other twin consists of a 1 in 8 chance of having it. In comparison to the chance for disorder in the general population is 1 in 100.
