Diagnosis For The Etiology Of Schizophrenia

A Comparison of Biological and Psychological Explanations of Schizophrenia Both the biological and the psychological explanations of schizophrenia are supported by empirical evidence which justify their explanations. However ,within the biological explanation there is the genetic explanation which is used largely based on scientific research such as that of Gottesman’s research using meta-analysis which looked at the family (including twin) relationships and concordance rates of schizophrenia. The studies used Gottesman’s research was scientifically based and because of the large number of studies and therefore the sample used, the biological research can be credited for being representative.

Schizophrenia is a brain disorder revolves the way a person would think, act and the way they would see the world. They usually have a different view of the truth and this is frequently loss of contact with what going on. People that have the disorder could hear or see things that don’t exist and even speak strange, believe that others are trying to harm them, or sense they’re being watched. The biological explanation for schizophrenia, through biological faults, for instance viral infections and brain abnormalities Genetic Factors Certain psychologists predict schizophrenia can be passed down generations however this implies some people inherit the disorder from their parents. Identical twins have a higher risk of schizophrenia, meaning one of the twins can have the disorder and is a greater chance is they’re identical rather than non-identical. During my research I found that ‘Gottesman’ (1991) reviewed 40 studies and established ‘monozygotic twins have a concordance rate of 48%’, whereas dizygotic twins have a concordance rate of 17%. This demonstrates the correlation between genetics and the risk of developing schizophrenia. However if there was no genetic element there would be no difference of risk from first relatives. Yet there is 1% possibility of someone at random picked. Adopted studies is way more real way of splitting out the effects of environmental and genetic factors- adopted children later progress schizophrenia and care

Outline and evaluate one or more biological explanations of schizophrenia (8 marks AO1/16 marks AO1)

Schizophrenia is a unique disease in its pathophysiology. For their early lives, patients appear healthy. However, symptoms begin to appear during adolescence or early adulthood and may be triggered by changes in the brain during puberty. The first signs of the illness include anxiety, depression, changes in friends, sleep problems, irritability, dropping grades, and having trouble concentrating (Picchioni and Murray, 2007; National Institute of Mental Health (NIMH)). Delusions and hallucinations typically begin between the ages of 16 and 30 (NIMH).

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.

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

Genetic factors of schizophrenia can be explained using studies on twins and studies on family history. With twin studies researchers want to establish the degree of concordance. This is

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

Schizophrenia is a psychological disease with an unknown treatment. Its onset starts in early adult hood on average. There are many studies showing links to genetics and environmental causes. In this paper I will discuss many of the signs and symptoms of schizophrenia along with how it is diagnosed, imaged with MRI, and the difficulty in treating this disease. More treatments for schizophrenia may be revealed with the further advancement of imaging technology. Schizophrenia is a disease that affects the most complex structure in the human body, the human brain. The more research that is continued on the smaller segments of the different areas of the brain with imaging modalities the closer we get to

The DSM VI list its diagnosis criteria for schizophrenia disorder here are a few: A. Two (or more) of the following, each present for a significant portion of time during a 1-month period (or less if successfully treated). At least one of these must be:

This paper defines schizophrenia from a biological and psychological perspective and also provides treatment to help combat symptoms of schizophrenia. This paper has three important contributions. First, by defining and expanding on schizophrenia from a biological perspective, I can identify the nature related predispositions. After expanding from a biological approach, secondly, I will analyze schizophrenia from a psychological aspect by determining if there is any environment or nurturing externals that can result to schizophrenia. Lastly, I will provide treatment details and also reveal early signs to schizophrenia. This paper is important because schizophrenia is an epic mental disease and it is crucially important to bring awareness to the public of how we can limit the illness. It is unclear whether schizophrenia have only a biological background or psychological background, but what was discovered is that both contribute to schizophrenia. Positive and negative treatment can be combatted undergoing pharmaceutical and psychotherapy,

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 theorists believe that individuals may have a genetic predisposition for the schizophrenia if a close family member has been diagnosed with the disorder. Stress during adolescent years seems to provoke the disorder among individuals who have a family history of the disorder. In addition, this theory suggests biochemical abnormalities related to the dopamine neurotransmitters may also contribute to the illness as the brains neurotransmission of the dopamine is too frequent in occurrence (Comer, 2005). CAT and MRI scans have also indicated that abnormal brain structuring may also play a role in the development of schizophrenia due to a common occurrence of enlarged ventricles within schizophrenia sufferers (Comer, 2005). Various parts of the brain may not develop for function properly which seems lead to Type II schizophrenia. Studies have also pointed towards the idea that exposure to certain viruses before birth may lead to the eventual development of schizophrenia (Comer, 2005).

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

It was known that schizophrenia is a heritable brain illness with unknown pathogenic mechanisms. Schizophrenia’s strongest genetic association includes variation in the major histocompatibility complex (MHC) locus. The genes and molecular mechanisms accounting for this, however, have been challenging to identify. The pathogenic mechanisms underlying schizophrenia are unknown, but observers have repeatedly noted pathological features including excessive loss of grey matter and reduced numbers of synaptic structures on neurons.
