Essay about Genetics and Schizophrenia - 1632 Words

This essay will discuss whether schizophrenia is genetically inherited disorder. There will be an understanding to what schizophrenia is with a brief description in the introduction. This essay will also talk about weather schizophrenia is genetically inherited or weather it is a biological (Inherited) disorder. It will also include weather schizophrenia is cause by other factors such as social factors, environmental, pre natal, childhood and neurobiology. The essay will also state weather schizophrenia is caused by a combination of the two. In 1908 Bleuler prised his own term schizophrenia from the Greek world’s schizien meaning to split and phren meaning mind to capture what he viewed as the essential nature of the condition. Bleuler†¦show more content†¦Reference One out of ten children of a schizophrenic parent will develop schizophrenia. The risk of 10% is greater then frequency of schizophrenia in the general population which is about 1% which would mean that schizophrenia is more likely to develop is some families than others most children of schizophrenic parents are completely normal. The most interesting investigation that is still going on that remains a mystery of schizophrenia is that genes alone do not explain who gets ill. Example of this is twins as all there genes are in common but if one of the identical twins has schizophrenia the other twin has the highest risk of developing schizophrenia. About 40% of twins of a schizophrenic live completely normal lives without disease. 1978 shields discussed 11 studies of the identical and non-identical co-twins of over 1300 schizophrenics from seven countries and then of these comparisons showed a higher concordance rate among identical twins. (A, C, Smith 1982 p.g 93) Research is still going on today to find out more about how genes and life events influence who gets schizophrenia. Carl Jung suggested that the presence of toxin x a mystery chemical that he though would eventually be identified. The demonstrated role of genetic factors in schizophrenia also suggested that biochemical’s should be investigated for it is the body chemistry and physiological processes that heredity may have an effect.

It used to be difficult to track how so many genetic regions evolved because of thousands of genes and DNA mutations involved in many psychiatric disorders. At the meeting of the American Society of Human Genetics in Orlando, Florida, in late October, several teams presented their findings on the possible links between the diseases and the conditions that drove its emergence andRead MoreHow Does Genetic Predisposition Enhances The Probability Of Schizophrenia?1795 Words   |  8 PagesSchizophrenia is a very but serious mental disease which 1.2% of the American population is diagnosed with this. . It s not known what causes schizophrenia, but researchers believe that a combination of genetics and environment contributes to development of the disorder. Problems with certain naturally occurring brain chemicals, including neurotransmitters called dopamine and glutamate, also may contribute. This is a disease that is said to begin in early adulthood, which is between 15 to age 25Read MoreThe Direct Genetic Loci Accounting For Schizophrenia s Heritability Is Still Unidentified1395 Words   |  6 PagesConclusion The direct genetic loci accounting for schizophrenia’s heritability is still unidentified. The mental illness affects approximately 3.5million Americans and 1 percent of the worldwide population today. The variable related to the disease is so widely ranged that literally anyone can have some form of potential risk. Compared to other mental disorders, schizophrenia is unique to having a combination of many different environmental, genetic, and biological factors. The exact cause of theRead MoreExplain the Difference Between Mendelian and Non-Mendelian Diseases.

Therefore, every pair of alleles in diploid organisms, are separated during meiosis and one allele for every trait is passed onto one of the two daughterRead MoreOutline and Evaluate One or More Biological Explanations to Schizophrenia1149 Words   |  5 Pagesone or more biological explanations of schizophrenia (8 marks AO1/16 marks AO1) Schizophrenia is classified as a mental disorder that shows profound disruption of cognition and emotion which affects a person’s language, perception, thought and sense of self. The dopamine hypothesis states that schizophrenic’s neurones transmitting dopamine release the neurotransmitter too easily, leading to the characteristic symptoms of schizophrenia. This hypothesis claims that schizophrenicsRead MoreThe Causes And Cures Of Schizophrenia938 Words   |  4 Pages The causes, cures and intellectual comprehension in schizophrenia patients remains unknown. Scientists have discovered that schizophrenia is a severe condition that develops by a combination of biological, environmental, and unforeseen factors. Since this condition effects no more than two percent of the population, it is challenging to find an adequate sample size for assessments and further study. People suffering from schizophrenia are incapable of determining reality and show a wide array ofRead MoreDevelopment of Schizophrenia660 Words   |  3 Pagesthe development of schizophrenia hypothesized that a large percentage of the onset of the psychotic disorder was due to genetic predisposition (Leboyer et al., 2008; Tsuang, Stone, Faraone, 2001). Meehl (1962) theorized that schizotaxia, a genetic predisposition for schizophrenia, inevitably results in schizotpy, the physical materialization of schizophrenia. Other early theories suggested that 80% of the likelihood of developing schizophrenia could be attributed to genetics (Leboyer et al., 2008)Read MoreOutline and Evaluate Two or More Biological Explanations of Schizophrenia.1443 Words   |  6 Pagesexplain the assumed causes of schizophrenia: Genetic and Dopamine Hypothesis. Research by Mikaywa et al has found that there must be a genetic explanation of schizophrenia due to the fact that concordance rates for environmental causes are not 100%. Also Mikaywa noticed that schizophrenia runs in the family, meaning there must be something other than environmental causes, causing the disorder. What Mikaywa studied was DNA from human families who were affected by schizophrenia and found that those withRead MoreNature Vs Nurture Debate1291 Words   |  6 PagesHow is the nature vs nurture debate related to a consideration of the mental disorder, schizophrenia? INTRODUCTION Schizophrenia is categorized by thoughts or experiences that seem abnormal with reality, disorganized speech or behaviour and decreased participation in regular daily activities. Difficulty with memory and concentration are sometimes also present. The two hit hypothesis generally refers to a genetic vulnerability, which is known as the first hit, triggered by something in the environmentRead MoreEssay Schizophrenia as a Biological Disorder798 Words   |  4 PagesSchizophrenia as a Biological Disorder As well as the biological approaches there are physiological, psychological and environmental explanations. New theories of schizophrenia are constantly being developed each having their own advantages and disadvantages. How do we know however, which one is correct? The biological explanation suggests that schizophrenia is produced by an unfortunate combination of genes or is due to physical problems in the brain. Researchers
