Biography
My name is Sherri Daniels and I am an avid learner for psychology. I am from Washington, D.C. and I got the wonderful opportunity to be a part of the Herd team at Marshall University. I have a twin brother, Terry Daniels, and I spend a lot of time with my family. I've been passionate about psychology since I was ending middle school. My mom has unfortunately been diagnosed with schizophrenia, so my interest in psychology has expanded. I always wanted to know the etiology and even the healing processes of obtaining a mental illness. Thank you for this COLA conference.

Abstract
Abstract
This literature review examines the biological and environmental risk factors in the etiology of schizophrenia. One study in schizophrenia is that biological factors can be the reason why one could develop the disorder. A second study is the dopamine hypothesis which states the elevated levels of the brain chemical dopamine can contribute to the development of schizophrenia. Based on the findings it shows that genetic and also prenatal factors can arise to a disadvantage of the brain. Genetic predispositions and obstetrical complications may contribute to the development of schizophrenia. Environmentally, exposure to stressful events can also trigger irrational behavior and thinking in the brain as well. In the diathesis-stress model it describes the heightened cortisol releasing the potential to intensify schizophrenia symptoms while augmenting dopamine activity in the environment. More recent findings show that genetics influences act in cohesion with environmental factors. Not only does one genetic finding impact the brain, but the other can also impact it. Based upon findings; genetics, prenatal and postnatal factors, brain abnormalities, and environment all have an impact on schizophrenia. Further research should focus on how biological and environmental factors impact the etiology of schizophrenia to aid in better understanding of the illness’s development.
