Biological Causes Of Schizophrenia

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

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.

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 characterized as a psychotic disease that dramatically affects one 's nervous system to a point of where every day basic functions can be inhibited. It is defined as the loss of contact with the external environment the person is in due to delusional thoughts and hallucinations. Perception and behavior of someone plagued with this disease is notably altered and their actions can become a concern of the people around them. Like many other diseases that affect the nervous system it is not curable at the current time but it can be treated to lessen the signs and symptoms of the disease.

Not every person with schizophrenia will have all symptoms, and the symptoms of schizophrenia may change over time.” (Schizophrenia: Sings, Types & Causes, Authors: Melinda Smith, M.A., and Jeanne Segal, Ph. D., Last Update February 2014, http://www.helpguide.org/mental/schizophrenia_symptom.htm) It is believed that no one single gene causes schizophrenia it is said that more than one gene is the cause of increased risk of schizophrenia there is a greater risk of a child developing it. There is more to this story than genetics; some type of early childhood trauma may play a role in schizophrenia. (The Causes of Schizophrenia http://www.nami.org/content/navigationmenu/mental_illnesses) The onset of schizophrenia occurs between the age of 15 and 45 in males, it is more common in males than females. There is talk from researchers about children with schizophrenia also having other mental disorders which include ADHD, ADD and bipolar disorder. Although there is not a tremendous amount of research they also believe that most children have had someone in their family who has been in a psychiatric hospital at some point and a family history of schizophrenia and some type of trauma. There is also a high number of suicide attempts in children with schizophrenia, there is also research to show that there is an increase of odds of schizophrenia in African Americans and Hispanic youth, however it is also very easy to misdiagnose these

Experts think that schizophrenia is caused by many contributing factors according to the NIMH and Berstein. Although there is a lot about schizophrenia that experts may not know, they do know that it is a genetic disease hat runs in families. According to the NIMH, those affected individuals are highly likely to have a close relative such as a mother, father, sibling, or grandparent with the disorder. According to Tischauser, a person with one parent who has the disease is ten times more likely to develop schizophrenia than a member of the general public. Thirty-nine percent of people who have both parents afflicted with the disease also develop schizophrenia. Schizophrenia majorly affects a person’s brain. The disorder disrupts the way that the brain cells function and communicate with each other. In the affected persons’ brain, the neurotransmitters that carry signals from one cell in the brain to the other may be abnormal or the transmitter may be malfunctioning (Bernstein). It is believed that several genes are associated with an increased risk of having schizophrenia. No single gene causes schizophrenia by itself. In fact, the genetic differences may include up to hundreds of different genes and the disruption of brain development. Bernstein states that we do know that there is an affected gene that is key to making important chemicals for the brain. Also, experts say that the environment is a factor in people with schizophrenia. For example, some environmental factors may include exposure to viruses, malnutrition before birth, problems during birth and other not yet known psychological factors. According to Anushree Bose, other factors that contribute to having schizophrenia include an imbalance of brain chemistry and different structures of the brain (7). The NIMH also adds that a person’s brain who has schizophrenia will look similar to a healthy person’s brain, but only in small ways. They

Schizophrenia is a very serious mental disorder. This disorder affects many people across the world as it does not matter an individual’s age, race, and their economic levels. An individual’s personality is distorted and they can lose their sense of reality where the individual has an unclear thought process, false beliefs, or even hearing voices. There have been mental disorders that add on to schizophrenia where the individual develops substance abuse, experience depression, and has an anxiety disorder and among other symptoms. Treatment for schizophrenia has come a long way in

Schizophrenia is a mental disorder that is thought to be brought on by certain genetic factors as well as environmental ones. It affects the way a person perceives reality. The person diagnosed with schizophrenia will often perceive auditory, visual, kinetic, and olfactory stimuli that aren’t actually present. The disease also affects how the person feels and acts as well.

The most common time for this disease to hit a person is around their early to mid-20’s (Schizophrenia and Psychosis Parah 13, 2014). Just like any other mental disease, there is no specific cause. Genetics, behavioral aspects, health aspects, and many other factors are thought to be a part of the cause of the disease but there is no proven evidence (Smith 2013). It is believed that a prolonged misuse of drugs or alcohol may lead to diseases such as schizophrenia (Phillips 4, 2000). If the disease runs in the family, then it is more than likely a close relative will get the disease later in life. “A child whose parent has schizophrenia has about a 10 percent chance of developing schizophrenia themselves.” (Smith 2013) Many believe that schizophrenia is inherited because genes are shared throughout the family and the mental disease is passed down through the family. Another possible cause of this disease is a bad brain development. Health professionals believe a cause may be from wrong chemical development or physical abnormality. “Neurotransmitters, substances that allow communication between nerve cells, have long been thought to be involved in the development of schizophrenia.” (Smith 2013) Due to more advanced technology today, scientists have become more aware of the differences between a healthy brain and a brain with schizophrenia. “For example, fluid-filled

Schizophrenia is severe disorder where there is a loss of contact with reality. It is mostly thought and emotion associated. This mental illness is quite common and has no cure. People who have schizophrenia are considers to have two minds. Many people with schizophrenia suffer and need to attend mental institutes, but today people have been functioning better with periodical hospital visits only. Most researchers consider schizophrenia a brain disorder. There is some evidence that suggests that schizophrenia begins in the womb.

One of biological explanations for schizophrenia is Gotessman (1991) theory. He proved that the probability that a patient's sibling becomes ill with schizophrenia is 9%. If both parents have a schizophrenic then there is a 46 % probability that their children will be also ill. Tienari (2000) analysed 361 Finnish children where 164 biological mothers has schizophrenia. It turned out that there is a high probability of schizophrenia in children adopted, but it is about 20% increased when adoptive families have experienced relationship disorders (child has been stressed). (Cardwell, 2012)

Schizophrenia has many biological components but genetics and environmental are the main two that will be spoken. Psychologists are looking to see if this mental illness is genetic by looking at the family history. By looking at the family’s ancestry, it can help find the origin of the mental illness at least in the person’s family tree. It also suggests that it’s a “highly heritable disorder of neurodevelopment, where the development and expression of positive or psychotic symptoms are best viewed as signifying the outcome of a pathobiological cascade which originates in early brain development.”(Paula et al., 2016). Meaning that schizophrenia is very likely to be genetic because of the way their brain is developed as a child which goes on

The most common risk factors for developing Schizophrenia involve genetics. You may be at risk for getting Schizophrenia if: anyone in your immediate family such as your mother, father, or siblings has Schizophrenia. If one parent has schizophrenia the risk is estimated at 13% for a child. Another factor is if your mother had certain health issues while she was pregnant with you such as malnutrition or a viral infection. Non- family risk factors for developing Schizophrenia include: growing up in dense urban areas, the use of street drugs by people under the age of 21, social isolation while growing up or during early years of adulthood, and being abused as a child. About 10 years after being diagnosed with Schizophrenia, about half of the

Schizophrenia is a severe mental disorder that affects how a person thinks, feels, and behaves. It causes affected people to have hallucinations and delusions, lack of motivation and content, and problems with understanding and using information.

There are many causes to Schizophrenia. Many causes are genetics, brain chemistry and structure, and the environment of a human being. Genetically Schizophrenia can run through a family and can be passed on generations at a time. “Individuals with a first degree relative (parent or sibling) who has schizophrenia have a 10 percent chance of developing the disorder, as opposed to the 1 percent chance of the general population.” (Helpguide.org) Identical twins are a good example of this. “If an identical twin is diagnosed with Schizophrenia the other twin is 50 percent more likely to also be diagnosed with the mental disorder (psychcentral.com).” Brain chemistry and structure is another big factor in the cause of Schizophrenia.
