Gene Of Schizophrenia Essay

778 Words4 Pages

Schizophrenia is a mental illness that affects millions of people all over the world. This illness has a gene that is related to it and could be the key to identifying the origin of schizophrenia. Neuregulin 1, often referred to NRG-1, has been linked in several different studies and reports as a gene that is susceptible to schizophrenia. There is an array of studies that have been conducted to drive us to the conclusion that NRG1 is the gene to focus on when looking for the trigger of schizophrenia. What exactly is schizophrenia? It is mental illness or disorder that affects at least 1% of the population worldwide. At the age of 20 is when most are diagnosed; though children under 12 and adults over 40 can be diagnosed, it is at times difficult. Symptoms can range and vary per person but are not limited to: delusions and hallucinations, paranoia, disorientation, or negative symptoms. It is categorized into two different disorders and at times both: neurodevelopmental or neurodegenerative disorder (Gupta and Kulhara). Gupta and Kulhara explore the origin of when schizophrenia became known and how it …show more content…

True gene because most do not concur with them that NRG-1 is the sole gene behind schizophrenia. Loh et al refer to NRG-1 as being at risk for the susceptibility, but do not fully agree that it is a risk. This goes back to a study that they conducted, it is to be noted that this study was done in Malaysia which differs from Iceland in the genetic makeup of its residents (Loh et al 2013 and Stefansson et al 2002.). In the study that was conducted by them, they found that alleles were differing between populations as well as the haplotypes that were meant to be susceptible. After all the testing was done they saw no evidence that there was a correlation between NRG-1 and

Supporting the DSM-5 checklist for a diagnosis of schizophrenia is the fact that the symptoms first began when Randy was in college and these have increased over time. The information provided on Randy’s family history, his school/social history, plus the description of his current lifestyle and the symptoms he now displays, could be used by the biological theorist

Aswin Sekar reasoned that the C4 gene leads to 'over - pruning' in the brain which will eventually lead to the deterioration of neural connections and disorders such as schizophrenia. This has opened a whole new frontier and furthered scientist's understanding of schizophrenia. My thought and reactions are that i'm still  perplexed at how a girl such as Sydney who, "grew up loving dance and Disney princesses" just snapped one day and started seeing monsters come out of her

Schizophrenia is a brain disorder that affects a person’s ability to think, feel, and behave. It often develops in men aged in their early twenties, however, is rarely found in men over the age of forty. Causes of schizophrenia include genetics, prenatal environment, brain chemistry, and substance use. To be diagnosed with the disease, a patient must persistently exhibit two or more of the above symptoms, as stated by the National Alliance on Mental Illness.

Schizophrenia is a brain disorder in which one interprets reality abnormally which some specialists have determined is caused by genetics and the environment one is surrounded by growing up. It was first classified in 1887 when Dr. Emile Kraepelin identified it but certain documents identify that it can be traced back to the old Pharaonic Egypt in 1550 BC, and as far back as the second millennium before Christ. There are several different beliefs as to why Schizophrenia is in some and not others. In Homerian epics and Greek mythology, Schizophrenia, which was to them, called madness, was similarly thought of as punishment from multiple gods, and it is in actual fact not until the time of the Greek physician Hippocrates from 460-377 BC, that

An outline of the causes and effects of schizophrenia Schizophrenia is a chronic mental disorder that is most commonly associated with delusion and hallucinations. It has been estimated that 0.4-0.7% of people develop schizophrenia, with the mental health condition being equally prevalent in both men and women (Saha et al., 2005). It is a particularly expensive illness due to its severity, reportedly costing the U.S. around $62.7 billion in 2002, with unemployment the most significant factor causing this staggering figure (Wu et al., 2005). While there is no known cause for the development of schizophrenia, a number of factors have been attributed to increasing the likelihood of someone developing the mental disorder.

In recent years, the general trend has progressed towards the biogenetic endorsement of Schizophrenia. The biogenetic model focuses on combining two previous models, genetic and biological, into one coherent framework (Angermeyer et al 152). By doing this, the hope that the negatives of one model would be balanced out with the positives of the other model. For example, a consequence of endorsing the genetic model was a phenomena called genetic essentialism. In a case study by Nicolas Rusch, he defines genetic essentialism as a mindset that “…implies that genes are the unchangeable basis of a person’s identity…” which subsequently increased the prejudice against the diagnosed (Rusch pg 328).

Scientists associated over 100 locations in the DNA to the probability of obtaining schizophrenia (Borenstein, 2014). After a recent examination of people with and without schizophrenia, it was found that there were 108 genes linked to the disorder (Feingold, 2014). 83 of these genes were not known beforehand (Borenstein, 2014). Also, there is a possibility that the abundance of unidentified genes could play a role in the obtainment of schizophrenia (Borenstein, 2014). There could be hundreds or thousands of unknown genes that are connected to schizophrenia (Sanders, 2014).

First of all, to understand Schizophrenia you’ll need to know about some of the symptoms that come along with it. Depending on the case, you could experience numerous things, some of which could be hallucinations, delusions, or talking in ways that others cannot understand. The symptoms come and go, and so far nobody has experienced all of them at once. Symptoms usually start between the ages of sixteen and thirty, and typically occur in men earlier than in women.

What are some thoughts that come to mind when a person brings up the word schizophrenia? According to Ford-Martin, “Schizophrenia is a psychotic disorder or group of disorders marked by disturbances in thinking, emotional responsiveness, and behavior” (2139). The character, Alice, from the film, Alice in Wonderland is a perfect example of schizophrenia, and the director, Tim Burton, further emphasizes the disorder by his use of film techniques. One characteristic of schizophrenia is delusions. According to Fallon, “The delusions of paranoid schizophrenics usually involve thoughts of being persecuted or harmed by others or exaggerated opinions of their own importance, but may also reflect feelings of jealousy or excessive religiosity” (2957).

I have recently started volunteering at the Meath Centre in Godalming, working with people who are suffering from Epilepsy. Some of them have Cryptogenic Epilepsy so also have other learning difficulties alongside their Epilepsy. The experiences I encountered from my volunteering furthered my interest in Epilepsy and other conditions affecting the brain. This made me keen to do more research into conditions that affect the brain and eager to find out what actually causes these abnormalities. I have, therefore, chosen to do an Extended Project Qualification with the title ‘Is Schizophrenia Better Understood From a Biological or Psychological Perspective?’

The symptoms are being divided into negative and positive which include hallucinations, delusions, behavior and disorganized speech. The latter symptoms include avolition, alogia, affective flattening and asociality (MHA, 2014). There is no clear cause of schizophrenia. Some theories about the cause of this disease include genetics, biology and possible viral infections and immune disorders. Scientist have been able to prove this disorder runs in families.

Schizophrenia is caused by structural abnormalities in the brain, although what causes these abnormalities is not explicitly known, scientists have pinpointed some factors. Genes certainly play a part, while 1% of the population suffers from Schizophrenia, there is a 10% chance of occurrence when a first-degree relative is diagnosed. It seems unlikely that just one gene causes the disorder, and it is hypothesized that many combinations of them lead to chemical or structural imbalances in the brain (National Alliance on Mental Health). Indeed, at Washington University scientists are working to analyze gene structures and have found that not single genes but gene clusters seem to serve as a sort of accurate predictor (Dryden, 2014). Some evidence
