Two Biological Explanations of Schizophrenia There are many biological explanations of schizophrenia. In this essay I will concentrate on the genetic explanation and biochemical explanation of the disorder. There are many studies that look in to genetics and the link to schizophrenia. This is dues to an original finding that schizophrenia runs in families and therefore suggests that genes are responsible for the disorder. I study was preformed by Janicak et al 2001; they found that monozygotic twins have a 48% concordance rate. This is considerably less in dizygotic twins where the concordance rate falls to 17%. This would suggest there is a strong case for genetics being involved with schizophrenia. However if the disorder was caused entirely by genetics then we would expect a 100% concordance with monozygotic twins. A supporting study is one by Kety et al. 1988. This study found 14% of biological relatives of schizophrenic adoptee were schizophrenic, and only 2.7% of adoptive relatives. This backs up the claim for geneti...
