How Does Genetic Predisposition Enhances The Probability Of Schizophrenia?

Adoption studies support the genetic theory that schizophrenia can be inherited as they provide evidence that the environment does not affect inheritance rate. The supporting study was carried out by Tienari in Finland. He investigated 164 adoptees that biological mothers have been diagnosed with schizophrenia and found 6.7% also received a diagnosis, compared to 2% of the control group of adoptees. This means that that there is a genetic liability to schizophrenia, as more of

Schizophrenia is a unique disease in its pathophysiology. For their early lives, patients appear healthy. However, symptoms begin to appear during adolescence or early adulthood and may be triggered by changes in the brain during puberty. The first signs of the illness include anxiety, depression, changes in friends, sleep problems, irritability, dropping grades, and having trouble concentrating (Picchioni and Murray, 2007; National Institute of Mental Health (NIMH)). Delusions and hallucinations typically begin between the ages of 16 and 30 (NIMH).

The direct genetic loci accounting for schizophrenia’s heritability is still unidentified. The mental illness affects approximately 3.5million Americans and 1 percent of the worldwide population today. The variable related to the disease is so widely ranged that literally anyone can have some form of potential risk. Compared to other mental disorders, schizophrenia is unique to having a combination of many different environmental, genetic, and biological factors. The exact cause of the disease is still unknown, but studies such as biometric and molecular screenings have proved genetic and biological factors, combined with environmental factors, is strongly connected to the etiology of the disease. Although schizophrenia is more commonly manifested during young adulthood, scientists believes, a variety of pre-birth factors are linked to the development of the disease. There are several prenatal factors that have a higher relative risk to the progression of schizophrenia as recorded by scientists. Although not proven, studies suggests time of birth, place of birth, infections during pregnancy, stress, malnourishment, and rh incompatibility are increased risk factors that shed light on possible causations of schizophrenia. Many studies are indefinite due to the latency, methodology, and of the disease, more research need to be established.

Modern attempts to revise forms of schizophrenia base on Langfeld’s approach. Schizophrenia disorders are characterized by mental and motor impairment, disturbances of sensory perception, temporary insanity. Some people have only one such psychotic episode; others have many episodes during a lifetime, but lead relatively normal lives during the interim periods. As a rule schizophrenia begins in early twenties.

(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 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

Schizophrenia can be a scary illness; its onset can seem sudden, for both the sufferer, family and friends must deal with such things as delusional psychosis, self-harm, and unpredictable outcomes. Researchers have tried to uncover how doctors can predict the onset of schizophrenia-and how some controllable factors, such as environmental ones, can help shape how the illness is experienced and treated. It is therefore important to understand, in studying the physiology of schizophrenia: to what extent is it determined by environment, and to what extent is it genetically predisposed? One way to study this question has been to look at studies in schizophrenia in twins and in adopted children, which is where this paper will direct its attention. This paper will also look at what researchers have found about the influence of family members on recurrence and severity of schizophrenic episodes. By looking at these three research-based studies, it becomes apparent that the answers to the questions researchers have about schizophrenia lie in the interplay between environment and genes.

The etiology of schizophrenia is unknown. As of today, research indicates a complicated interaction between inherited and environmental factors. Researchers are investigating numerous potential factors, including

What is Schizophrenia? Schizophrenia is defined as a psychotic disorder that strikes about one percent of the world population. It is a disease that makes it difficult for a person to think logically, to tell the difference between real and unreal experiences like hallucinations, delusions, hearing voices, and paranoia. It surfaces more frequently during a person’s late teens to early twenties, and it has the potential to destroy the lives of the people who are unfortunate enough to be its victim.

This essay will discuss whether schizophrenia is genetically inherited disorder. There will be an understanding to what schizophrenia is with a brief description in the introduction. This essay will also talk about weather schizophrenia is genetically inherited or weather it is a biological (Inherited) disorder. It will also include weather schizophrenia is cause by other factors such as social factors, environmental, pre natal, childhood and neurobiology. The essay will also state weather schizophrenia is caused by a combination of the two.

Schizophrenia is a very serious, long-term disorder that affects about 1% of the world’s population. It affects people anywhere from twenty years old, to forty-five years old. It is known to be one of the most disabling diseases in this age group. Schizophrenia can break down a person’s behaviors, emotions, and thoughts. People who suffer from schizophrenia usually show very inappropriate displays of their actions and feelings. Sufferers have been known to hear voices, even when there is nobody around them. They have problems controlling their thoughts, and sometimes blurt out things that are very inappropriate. This paper will outline the biological, social, and psychological

Even with all the criteria for Schizophrenia that I described above, still there is no apparent reason as to what the risk factor of Schizophrenia is. Which lead to my research to indentify certain certain Risk factors associated with with Schizophrenia. During my research, I was able to discover many risks factors, but I chose to only discuss the few that are very common through most

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.

In some people's cases, Schizophrenia appears suddenly and without warning. But for most it comes slowly, with subtle warning signs and a gradual decline in functioning long before the first severe episode. “In the early phases of Schizophrenia people often seem eccentric, unmotivated, emotionless, and reclusive (Helpguide.org).” They may isolate themselves and not want to participate in daily activities such as playing with their children, going outside, or getting off the couch. They abandon their hobbies and they do not do well in their jobs. “The most common early warning signs of Schizophrenia include: social withdrawal, hostility or suspiciousness, deterioration of personal hygiene, having a flat and expressionless gaze, the inability to cry or express joy, inappropriate laughter or crying, depression, oversleeping or insomnia, odd or irrational statements, forgetfulness or the inability to concentrate, extreme reaction to criticism, and or strange use of words or way of speaking (Helpguide.org).” There are five types of symptoms of Schizophrenia. Positive is a symptom that involves having hallucinations or delusions. Negative is when one shows no emotion or flat behavior. Avolation is when a person shows little interest in whatever they are doing. Cognitive behavior is when you have disorganized speech or memory loss. Catatonic behavior is considered poor functioning such as your voluntary muscles

Schizophrenia is a chronic psychiatric illness, with a relapsing and remitting course. It is a syndrome; namely a collection of signals and symptoms of unfamiliar aetiology, and is usually associated with communal and occupational working impairment. Schizophrenia has a prevalence of one each cent in the finished population. Genetic and environmental factors have been implicated in the aetiology of the illness, and genetic factors.
