A Comparison of Biological and Psychological Explanations of 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.

In an attempt to gain a position as a psychologist, I will be discussing schizophrenia and the disorder’s casual factors, associated symptoms, the areas of the brain it affects, and the neural basis of the disorder. I will continue on to discuss appropriate drug therapies. In addition I will also be reviewing two separate case studies, each on a different disorder. I will be examining each problem from the perspective of a bio psychologist. I will define the patient’s diagnosis at length I will relate each case to the nature-nurture theory, and talk about any helpful drug interventions or solutions for each disorder. When talking about drug intervention, it is also important to discuss the positive and

Adoption studies support the genetic theory that schizophrenia can be inherited as they provide evidence that the environment does not affect inheritance rate. The supporting study was carried out by Tienari in Finland. He investigated 164 adoptees that biological mothers have been diagnosed with schizophrenia and found 6.7% also received a diagnosis, compared to 2% of the control group of adoptees. This means that that there is a genetic liability to schizophrenia, as more of

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.

Research by Johnstone in 1994, explained the biological approach of interventions, explanation and treating of schizophrenia patients (Hansell & Damour, 2005). In studies of Fisher in 2001, discoveries that the brain had more dopamine receptors know as B_2 receptors in a person suffering from schizophrenia, than a non-suffer (Hansell & Damour, 2005). Biological findings of schizophrenia suggest that a genetic factor was hereditary, but not conclusive because the element of environment does make a difference (Hansell & Damour, 2005).

Schizophrenia is a psychotic disorder characterized by distorted thinking, impaired emotional responses, poor interpersonal skills and a distortion of reality. It is the most common of psychotic disorders that, in most countries around the world, affects around 1 per cent of the population. In terms of explanations for the disorder, two central types of explanations arise – psychological explanations and biological explanations. Whereas psychological explanations tend to focus on cognitive, emotional and environmental factors that may cause the disorder, biological explanations tend to focus on genetic, biochemical and neuro-anatomical factors as the cause of the

The scientific interpretation of schizophrenia was one that supported a physical basis which was attributed to an imbalance in the cognition of humans. The goal of natural science aimed in finding rational, scientific causes, that would lead to biological

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.

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.

Researchers favouring the biological explanation look at genetic factors, brain structure and biochemical explanations. Many researchers would suggest that the debate over whether schizophrenia is passed down through genetics is no longer a

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

Conclusions / Results: Conclusions suggest that the nature vs nurture dichotomy may not be as relevant as looking at the interaction between these two forces. It was discovered that while one’s genetic heritage creates a predisposition towards schizophrenia, other factors such as the home environment, the parental environment, dietary factors and others may determine whether the disease is manifested.
