Mental Health Illnesses Have A Genetic Contribution

Studies revolving around twin and family history have been proving to show that mental health illnesses have a genetic contribution. Mental health professionals have long known that certain mental illnesses can run in families, due to the fact that most, the chance of obtaining schizophrenia or bipolar disorder with no genetic factor is around one perfect, as to where if someone has a close relative with a certain disorder, such as a parent or sibling, the risk factor jumps to around ten percent. The genetic force behind the abundance of mental illnesses is especially strong in identical twins who have a risk factor of a little less than fifty percent. Mental disorders are actually not about an individual gene, but about a multitude of…show more content…
As of 2002, genes have appeared to influence the development of mental illnesses in three major ways: they may ultimately lead to causes that cause disorders such as Alzheimer’s or schizophrenia; they could possibly be responsible for the abnormalities in an individual’s development before or after birth; and lastly it can enhance a person’s susceptibility to depression, multiple anxiety disorders, substance abuse problems, or personality disorders. One technology achievement that has been contributed to the vast advances in the study of biological psychiatry in the last twenty years is high-speed computing. The faster computers have enabled researchers to advance rough estimates of heritability of multiple disorders to being able to accurately compute the quantifications of genetic effects. In multiple cases the data achieved by these supercomputers have led to significant studies of the causes of specific disorders. For instance, in the 1960s and 1970s, schizophrenia was believed to be caused by the lack of affection toward a child by their mother, however, it has been said that the heritability of the disorder may be as much as eighty percent and not actually from the cold hardness of a mother. Another illness proved wrong is autism. Autism was blamed by faulty parenting, but is now known to be more than ninety percent heritable. (“As
