Cause Of Schizophrenia Essay

Expert’s reason that unevenness in the complicated interconnected chemical responses of the brain connecting the neurotransmitters dopamine and glutamate, and maybe others, performs a part in schizophrenia. Neurotransmitters are elements that permit brain cells to interconnect with each other. Experts are acquiring more about brain chemistry and its connection to schizophrenia. Similarly, in small methods the brains of people with schizophrenia appear diverse than those of healthful people. For instance, fluid-filled holes at the middle of the brain, called ventricles, are greater in certain people with schizophrenia. The brains of people with the disorder similarly manage to have less grey matter, and certain

Schizophrenia is a neurological disorder that affects the cognitive functions of an individual. The cause of this illness is unknown, but there are several theories of how an individual may acquire schizophrenia. Because there are many symptoms of the disease and because the symptoms can vary quite dramatically among several individuals and even within the same individual over time, the diagnosis of schizophrenia can be quite difficult.

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

First off I would like to tell you what exactly schizophrenia is. Schizophrenia is a brain disease, with concrete and specific symptoms due to physical and biochemical changes in the brain. This illness strikes young people in their prime age usually between 16 and 25. Schizophrenia is almost always treatable with medication. Contrary to what most think schizophrenia is not a "split personality", or caused by childhood trauma, bad parenting, or poverty, and not the result of any action or personal failure by the individual.(3)

Genetics can cause differences in brain chemistry and biochemistry may be important in the development and maintenance of schizophrenia. The dopamine

Schizophrenia is a chronic, lifetime mental disorder that cannot be cured, but can be effectively treated and managed. Research conducted in developed countries revealed that about 20 to 35 percent of patients undergo a rapid improvement when treated. Approximately, 70 percent of the patients suffer a relapse of acute symptoms within the next 2 to 5 years after being discharged from hospital. The risk of relapse usually decreases 10 years after the initial onset.

Many areas of the brain, along with chemicals are affected in a schizophrenic patient. The structure along with the function of the brain would be abnormal in comparison to a healthy functioning brain. The causes of many symptoms contributing to schizophrenia are still unsure of, and are instead hypothesised.

The cause of this condition is not known, but there has been studies of a specific gene referred to as the “schizophrenia gene” that controls the production of new neurons and how they are integrated into the brain’s existing network. This gene, along with any imbalance of dopamine and environmental factors could all combine to cause schizophrenia.

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).

Over the years, experiments have produced evidence to suggest that dopamine plays a role in the development of Schizophrenia (Howes, McCutcheon, & Stone, 2015). Dopamine is a neurotransmitter that is produced in the substantia nigra and ventral tegmental regions of the brain. The belief that dopamine was involved in Schizophrenia arose after multiple studies performed with compounds produced an increase in extracellular concentrations of dopamine (Lieberman, Kane, & Alvir, 1987). The patients that were administered these compounds had similar symptoms to those observed from patients who were diagnosed with Schizophrenia (Lieberman et al., 1987).

There are a ton of reasons for one to be diagnosed with schizophrenia. Schizophrenia is a long-term mental disorder of a type involving a breakdown in the relation between thought, emotion, and behavior, leading to faulty perception, inappropriate actions and feelings, withdrawal from reality and personal relationships into fantasy and delusion, and a sense of mental fragmentation. Schizophrenia can be hereditary in some cases but in most it has been known to be environmental. One cause liked to schizophrenia is low levels of folate acid and defective folate metabolism which mean the MTHFR gene mutation can lead to schizophrenia in some cases.

Still, these causes are just factors and not sole causes of schizophrenia. MacPherson says that low self-esteem, repressed feelings, and a past of psychological abuse encourages one to compare their own self with the selves of society which leads to one’s emotions being split (MacPherson). It is argued that psychologically stressful situations like a loss of job, bereavement, divorce, or abuse don’t cause schizophrenia but trigger the development if it is already there (NHS). The person’s brain reacts differently to these situations. Dopamine is a chemical in our bodies that regulate mood. When a person’s dopamine levels drop to low, they become depressed. However, if it gets too high then a person can hallucinate and have delusions. In schizophrenia patients, their brain releases dopamine after stressful situations (Brisch et al). It is also observed that anything that causes extra release of dopamine including adolescent marijuana use increases the risk of schizophrenia (Brisch et

Schizophrenia is a psychotic disorder that causes severe mental disturbances which disrupt ones thoughts, speech, and behavior. According to Paul Thompson, Associate Professor of Neurology, one percent of the world’s population suffers from this disorder. There is no one specific cause of schizophrenia, because it is caused by a combination of problems during development. It is a disorder which not only affects the patient, but their family and society as well. Schizophrenia can be a debilitating disorder, however, there are many treatments that can allow people who suffer from it to lead normal lives.

If the chemicals in the brain are having trouble going through the brain then that can cause a psychological disorder such as Schizophrenia. There is also evidence to suggest that the brain of people with Schizophrenia is different than those that have healthier brains. “Some studies also suggest that abnormalities in the temporal lobes, hippocampus, and amygdala are connected to schizophrenia’s positive symptoms (hallucinations or delusions) (Helpguide.org).” In my opinion, the environment one endures can be the biggest factor in the cause of schizophrenia. Child abuse, early traumatic events, severe stress, and negative life events can all have a very huge impact in the cause of Schizophrenia. What someone went through in their past can determine their future.
