The Etiology of Schizophrenia

Introduction

Schizophrenia is a disorder of psychotic intensity characterized by profound disruption of cognition and emotion, including hallucinations, delusions, disorganized speech or behavior, and/or negative symptoms. This entry reviews the epidemiology of schizophrenia, along with its natural history and risk factors.(Suddath, 2003) It focuses on the period since the review by Yolles and Kramer in 1969, concentrating on results that are most credible methodologically and consistent across studies, and on the most recent developments.

The most important role of biological science is to help us better realise ourselves. One facet of comprehending us is comprehending why things go wrong with our bodies and biological science can help us do that. Schizophrenia is a very awkward infection in our world today. It is a mental infection which determinants paranoia, hallucenations, and disassociation from the genuine world and many other problems. The biological causes of schizophrenia are both controversial and important to realise as one million to two million people have long-term schizophrenia, and 100,000-200,000 persons become schizophrenic every year. Fifty percent of people in hospital psychiatric care have schizophrenia (Boyle 2002). The cause of schizophrenia is not known. However, both nonbiological (psychological) and biological (familial, chemical imbalances in the brain) factors are thought to be involved. As technology allows disorders of the brain to be further defined, biological causes are becoming better understood. These biological issues will be further discussed as this is my focus. Genetic predisposition, infectious agents, allergies, and disturbances in metabolism are biological issues that have been studied in the cause of schizophrenia.

Biological Causes of Schizophrenia

Chemical Imbalances

No clear answer has been granted to the inquiry of what determinants schizophrenia, but as expertise improves so does the study to what performances a vital function in evolving this disorder. So far there have been three main assisting components scientists are researching: genetics and heredity, chemistry, and difficulties during pregnancy and birth (mhscc). Firstly, it appears that multiple genes are involved in creating a predisposition to develop the disorder. Factors such as prenatal adversities like intrauterine starvation or viral diseases, prenatal difficulties, and various nonspecific stressors, seem to influence the development of schizophrenia. Secondly, with the use of chemistry, one can number, through the use of genetics, how the mind uses certain chemicals. People with schizophrenia have a chemical imbalance within them; this means that the individual diagnosed have either very perceptive to or produce an excessive allowance of dopamine, a mind chemical. Dopamine, a neurotransmitter, permits nerve units in the mind to drive certain notes to each other. The imbalance of this chemical can sway the way a person's brain may answer to a stimuli. Lastly, some researchers suppose a viral disease or improper nutrition throughout a pregnancy of a child. These birth complications may boost the possibilities of a person evolving schizophrenia. Although many other determinants may ascribe to the infection, genetics, chemistry, and difficulties during a pregnancy generally recounts how schizophrenia may be caused.
