The Psychological Disorder Of Schizophrenia

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 with the disorder are more likely to have the defective gene: PPP3CC. The PPP3CC gene regulates the immune system, and therefore is an important gene in terms of genetic vulnerabilities which may be

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.

According to NAMI (), schizophrenia is a long term mental illness that interferes with a person’s ability to think clearly, make decisions, and relate to others, impairing a person from functioning to their full potential when left untreated. For these persons affected, it is many times difficult to distinguish what is real from what is not. “Unfortunately, no single simple course of treatment exists.” Research has linked schizophrenia to a multitude of possible causes” (NAMI).

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

(Do People Inherit Schizophrenia?) Research shows that the disease is not caused by a single gene but has to do with several different ones. People with the disease also have higher rates of extremely rare genetic mutations that may occur when a specific gene that produces important brain chemicals malfunctions. However, it is not yet possible to use genetic information to predict whether a person will develop schizophrenia or not.

Schizophrenia is a chronic brain disorder that affects more than one percent of the population. When schizophrenia is active, symptoms can include delusions, hallucinations, trouble with thinking and concentration, and lack of motivation. However, when these symptoms are treated properly, a large portion of those diagnosed will greatly improve over time.

Schizophrenia is a disorder that has an effect on about 25 million people around the world (Myers, 2010). Schizophrenia is a brain damage, naturally created by the human body, that is caused by the genetically determined vulnerability of the blood-brain barrier (Voronov, 2013). This psychiatric disorder, like most others, is characterized by changes in behavior, thinking, reduced ability to feel normal emotions, and mood (Abad et al., 2011). The unique thing about schizophrenia is that the symptoms are split into two different sections: positive symptoms (the presences of behaviors and or feelings that are not usually present in humans) and negative symptoms (the lack of behaviors and or feelings that are usually present in humans). Positive symptoms are characterized by the patient having delusions and or hallucinations while negative symptoms are characterized by the patient having affective flattening, alogia, avolition, anhedonia, and asociality (Nasrollahi et al., 2012). Although these are general symptoms for schizophrenia, the symptoms differ between genders.

It has been long understood that schizophrenia runs in families. People who have a close rela-tive with schizophrenia are more likely to develop the disorder than are people who have no relatives with the illness. A child whose parent has schizophrenia has about a 10 percent chance of developing schizophrenia themselves. Identical twins carry the same genes. In iden-tical twins, if one twin develops schizophrenia, the other twin has one in two chance of de-veloping it too even if they are raised separately. People who have second degree relative,

Schizophrenia is a mental illness that is in a very small amount of the population, 1 in 100 people (1% of the population). Symptoms of schizophrenia include, delusions, hallucinations, disorganized speech and behavior, not much emotion if any is present, as well as speech and socializations issues. Ways to treat schizophrenia are very limited to antipsychotic drugs and therapy. Although there is not one cause to this illness found, there are many factors that explain the cause or result in having schizophrenia. Substance abuse and stress are also contributing factors in schizophrenia when it comes to patients with this illness having violent personalities as well as suicidal thoughts.

Schizophrenia is a class of mental disorders often symptomatic of a broad spectrum of behaviours which ultimately fail to determine what is real. Some of the symptoms that make up the spectrum of schizophrenia include hallucinations, invalid or illogical beliefs or thought processes, and abnormal social expression. It is worth noting that schizophrenia does not mean multiple personality disorder but rather a separating of mental function and is also rarely diagnosed separately but along with other conditions, such as depression, mania, and anxiety disorders. As to the causes of schizophrenia, both genetic [1] and environmental factors [2] have been found to influence the progress of schizophrenia, but there is still much which is unknown

Research has shown that one of the main factors of schizophrenia is genetics. Despite the fact that there has

Many studies have reported that the main cause of schizophrenia is unknown. The results of the disease are from combination between influences of biological, psychological, and environmental factors (Townsend, 2015).regardless of the exact causation, the results is impairment in brain function that may produce the psychotic symptoms that can be seen in the diagnosis of schizophrenia (tusae). Even though researchers are still struggling for additional facts about the etiology and development of schizophrenia. Schizophrenia typically presents in a gradual onset of abnormalities in perception, though, motion, and behavior often during young adulthood (). Patient with schizophrenia often suffer from terrifying symptoms such as auditory hallucination,

Schizophrenia is a Psychological disorder that impacts the person 's ability to process thoughts, emotions and action. Schizophrenia symptoms are categorized as cognitive, positive and negative symptoms. There has yet to be a confirmed singular cause of schizophrenia. The dopamine hypothesis is a theory that attributes the cause of schizophrenia to an increase in dopamine levels. The antipsychotic medication mentioned in this theory is beneficial in the treatment of the symptoms of schizophrenia. Although the medication that treats increased dopamine levels it does not affect other

Genes have been known to play an active role in schizophrenia. It is difficult to ascertain the exact effect because there is heavy variation. Also, people who have a first-degree relative suffering from schizophrenia have 6.5% more chances acquiring it than others. Monozygotic twins have 40% or more the risk is 13%or more the figures surely look scary to people who have a history of schizophrenia and given the above facts, a direct relationship between schizophrenia and genes cannot be ignored.

Not much is known about what exactly causes schizophrenia, or which parts of the brain are affected. One guess to the cause of schizophrenia is that neurotransmitter dopamine is involved. "Some of the supporting evidence behind this theory is the fact that amphetamines, when given in large doses, causes the brain's dopamine levels to rise, this can cause the subject to show schizophrenia like symptoms" (Torrey, 1983). There are three different fields of thought
