Outline and Evaluate One or More Biological Explanations to Schizophrenia

Kety asked two groups of adoptees: who had schizophrenia, and a matched group who didn’t. The disorder was related in the biological and adoptive families of the two groups of adoptees – this was larger among biological relations of the schizophrenic adoptees than between ones of the controls, this supports the genetic explanation.

Those that are recognized increase the possibility only by extremely small quantities. Consequently, these “genome scans” are improbable to offer a whole image of a person’s danger for acquiring a mental disorder like schizophrenia. Additionally, it possibly endures more than genes to instigate the disorder (Stefansson, Ophoff, Steinberg, Andreassen, Cichon, Rujescu, & Kahn, 2009). Experts reflect communications amongst genes and the environment are essential for schizophrenia to grow. Several environmental issues might be comprised, such as revelation to viruses or malnourishment before birth, difficulties during birth, and other not yet recognized psychosocial issues.

Genetics play a role in the development of schizophrenia. When looking closer at the brain chemistry between a person with schizophrenia and a person with out schizophrenia there are

There are two main biological theories which explain the assumed causes of schizophrenia: Genetic and Dopamine Hypothesis.

The term ‘schizophrenia' covers a group of serious psychotic disorders characterised by a loss of contact with reality. It comes from two Greek words: schiz meaning ‘split' and phren meaning ‘mind'. DSM IV (1994) estimate that the occurrence rate of schizophrenia ranges from 0.2%-2.0% worldwide. There are two main explanations of schizophrenia: the biological explanations and the psychological explanations. In this essay I will critically consider the biological explanations. These include genetics, neurochemistry, brain structure and evolution.

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.

Schizophrenia is a chronic, complex disorder that causes neurotransmitters to disrupt functional circuits within the brain (7). “Approximately 1% of the population worldwide will develop schizophrenia during their lifetime” (6).

Biological, psychological, and sociocultural viewpoints have been developed in an attempt to explain schizophrenia. All three viewpoints point out various factors that may contribute to the development of the disorder.

Schizophrenia 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.

Schizophrenia can be passed down thru generations even though there is not a specific gene associated with the disorder. It is considered to be a combination of genes that make a person susceptible to becoming schizophrenic. This information is found mainly thought the study of twins. By having the same genes it can be viewed why genes contribute to the potential of schizophrenia. Even though genetics is a viable factor in the analysis of the cause of schizophrenia there are more supporting factors found in neurotransmitters.

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.

Schizophrenia is a very serious, long-term disorder that affects about 1% of the world’s population. It affects people anywhere from twenty years old, to forty-five years old. It is known to be one of the most disabling diseases in this age group. Schizophrenia can break down a person’s behaviors, emotions, and thoughts. People who suffer from schizophrenia usually show very inappropriate displays of their actions and feelings. Sufferers have been known to hear voices, even when there is nobody around them. They have problems controlling their thoughts, and sometimes blurt out things that are very inappropriate. This paper will outline the biological, social, and psychological

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 of symptoms varying from delusions, hallucinations, irrational conduct and disorganized speech. The complex severity of these symptoms make it difficult for scientists to find a remedy that works for all patients. Recent studies have shown that identical twins have an increased risk of developing the condition. The risk is increased by half in comparison to individuals who do not carry twin genetics. Many wonder if schizophrenia is caused by a physical abnormality inside the brain, but it has not been scientifically proven yet. Since twins are at the highest at risk for schizophrenia, it is essential to study the behaviors, patterns and recovery methods of these patients.

Within twins, monozygotic twins have a 48% probability if their twin is diagnosed with schizophrenia, and with dizygotic twins it is a 17% probability (Kalat, 2015). This shows that there is a genetic bases for schizophrenia, it also highlights that other non-genetic factors must play a role in the development of the disorder. These results have been backed by many research carried out on adoption studies. An adoption study in Finland carried out aimed to test the hypostasis that family rearing plays a factor in the development of schizophrenia (Tienari et al, 2004).Their research found that adoptees at high genetic risk (biological mother had schizophrenia) were more sensitive to problems in the adoptive family environment. Adoptees with high risk and a severally dysfunctional family rearing were significantly coordinated with a diagnosis of a schizophrenia spectrum disorder (Tienari et al, 2004). In support of the diathesis model neither high risk nor dysfunctional rearing were significantly linked with a diagnosis (Tienari et al, 2004). The research found that a ‘healthy’ adoptive family, acted as a ‘protective effect’ for the adoptees with
