Dangerous Mind - Psychology

Approximately one out of every four Americans suffers from some form of mental disorder in a given year. About 3.5 million Americans suffer from severe mental illnesses like schizophrenia and manic-depressive illness. At least 40 percent of mentally ill people do not seek help or are not being treated, while many wander the streets homeless (Kornblum).

As stated by NIHM, the prevalence of schizophrenia is about 1 in every 100 people in the general population. Ten percent of the people who have first degree family members with the disorder, such as a brother, sister, or parent, also have schizophrenia. A

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.

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

John Nash was extremely intelligent man but let his work take over a lot of his life. I would describe his attitude as cocky as he believed he was much smarter than others and loved to prove it which is shown in the beginning with the board game between him and Hanson. I figured that he was one that knew he was there for the education and not to party like his fellow classmates were doing. He would stay in his room studying and figuring out the hardest math problems and working them on the windows. Figuring out math problems was what made his day.The clues that were the most alarming were when Nash and Charles are sitting on the roof they are chatting on a university building roof and getting to know each other better. Nash and Charles are

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).

Incidence rates and causes of Schizophrenia are suggested that about 1.2 % of American population is diagnosed with the schizophrenic disorder. Leaving

Currently there are no cures for schizophrenia, but the symptoms are helped by taking antipsychotic medication. The symptoms experienced by those with schizophrenia are grouped in to three categories: negative symptoms, positive symptoms, and cognitive symptoms (Regier 1993, p.92). The positive symptoms include, hallucinations, delusions, unusual or dysfunctional ways of thinking, agitated body movements. Negative symptoms include, flat affect, reduced pleasure in everyday life, difficulty sustaining tasks, and reduced speech. Cognitive symptoms include, disruption in executive functioning and working memory, as well as reduced ability to concentrate. The etiology of schizophrenia is still debated by psychologists and neuroscientists, but factors such as neuroanatomy, and environmental influences are believed to play a key role. A genetic predisposition to schizophrenia has been established by researchers, but it remains unclear what causes the phenotype to be expressed. The most agreed upon cause of schizophrenia refers to the diathesis-stress model, which explains schizophrenia as a response to an individual’s allostatic load becoming too much for the brain to cope with. Another popular explanation amongst neuroscientists is the dopamine

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 mental illness that inhibits a person’s ability to think clearly, manage their emotions, make their own decisions, and associate with others. It is a complicated, long term illness that affects one percent of Americans. Even though Schizophrenia can occur at any age, it is more common for men in their early twenties and early twenties to late thirties in women. It is possible to lead a happy, fulfilling life with Schizophrenia. (Nami 2016)

According to James G. Hollandworth of the University of Southern Mississippi, schizophrenia is primarily characterized by a disintegration of reality perception, consciousness, and thought process which results in a debilitated proficiency in social and professional faculties (Hollandworth, 1990). While schizophrenia can most arguably be classified as a predominantly genetic affliction, there are others factors which can contribute to its development even without a genetic predisposition. These elements include birth defects such as hypoxia and low birth rate, neuroanatomical anomalies, viral infections, along with low IQ and cerebral atrophy (Hollandsworth, 1990). While these components in themselves are not sufficient enough to cause the disorder, they result in an increased risk for developing the disease. One theory for the cause of schizophrenia that has been studied with great validity is the dopamine hypothesis. This theory postulates that schizophrenia is caused by an overabundance of the dopamine-dependent areas of the brain causing an imbalance that affects the entire system (Hollandsworth, 1990). For this reason many of today’s schizophrenia treatment drugs inhibit dopamine receptor activity in an attempt to return it to its natural equilibrium. Although even with advances in modern science and new drugs being developed every day, the illness is still only treatable and its symptoms still emerge even

Schizophrenia continues to create new challenges today and continue to be a complicated mental illness. Contrary to the misconception that Schizophrenia is a rare condition, it is not rare at all. ; each person has a risk of developing it within their lifetime. It is most common to psychoses and half of the inpatients in mental facilities are Schizophrenics. Schizophrenia is a brain disorder that can happen to anyone occurring in any culture, affecting men and women equally and all areas of functioning, including emotions, perception and behavior.

(Szasz,1982, p.4, p.29) In 1900, the term schizophrenia, now used worldwide, was used to describe the condition that one out of every hundred people had. This statistic remains the same today. Through research and years of study, the world has a better understanding of schizophrenia, its forms, characteristics, symptoms, types, possible causes, and treatments, if any. ( Pierce, 1990. p.263 )

Schizophrenia is more common than the average person believes it to be. According to SARDAA (Schizophrenia and Related Disorders Alliance of America), approximately3.5 billion people in the United States have schizophrenia. Additionally, a great portion of this population is homeless, and about half of everyone diagnosed have never received treatment for it (SARDAA, 2014) . For something that is so popular in our society today, it is important to understand what schizophrenia is and how it is diagnosed.

This doesn't seem like a big number but it comes out as 77 million people. When one is diagnosed with schizophrenia, they become irritable, angry, delusional
