Risk Factors Schizophrenia

Risk Factors SchizophreniaThe Effect of Perinatal Risk Factors on the relative incidence of SchizophreniaBackgroundDeveloping schizophrenic psychosis is hooklike on varied factors. A person who could possibly develop the illness later(prenominal) in life is faintly unusual in terms of cognitive skills, travel functioning, and social behavior as comp atomic number 18d to his or her peers. This states that indicators exist as to whether a person will be vulnerable into macrocosm a insane later in life, as set(p) by certain abnormalities that quite a little be observed (Mortensen, 1999 and Dean, 2003).Most of the causes being held accountable for the nurture of schizophrenic disorder female genital organ be traced back to genetic or biological factors and environmental exposure that operated first in life of the individual (Dean, 2003, Khasshan, 2008, Mednick, 1970, and Mortenen, 1999).Evidences regarding the effects of obstetric complications, antenatal illness, misuse o f drugs, migration and travel, urbanization, and various life experiences on the intrusion of schizophrenia in later years in life maintain been noted. These were horizontal incorporated and represented in causation models that encompass psychological, genetic, environmental, and social elements. These evidences dismiss be used as models for clinical and research purposes of determining the run a assay of schizophrenia, as they cover a wide range of causative get onnts (Dalman, 1999 and Dean, 2003).It has been a challenge for researchers to understand the cause of schizophrenia, the etiology of which has brought about several hypotheses (Dean, 2003). unlike happen of infection factors affect the incidence of the illness, two of which will be assumption more attention in this paper. A number of epidemiological studies allow indicated an change magnitude happen of developing schizophrenia among people who were exposed to paternal infections much(prenominal) as three-day measles virus and influenza virus in utero (Westergaard, 1999). Other studies have shown that children who were innate(p) during inclement weather have an increased risk of developing schizophrenia. These are supported by researches conducted on a population basis (Mortensen, 1999).PurposeAs stated by the report conducted by Mortensen and opposites (1999), the location and the season of have of an individual qualification be important in the instruction of schizophrenia. Aside from family history, these environmental factors can be associated with the onset of the disorder. Prevalence studies of Westergaard and others (1999) also showed that exposure to prenatal infections might be a factor in the evolution of schizophrenia later in life. There is, however, a poor evidence of a strong tie-up between development of schizophrenia and exposure to influenza viral infection. This hold out the group into determining whether or not prenatal exposure to epidemic roseola would ind eed be a factor for schizophrenia development. This is in conformity with previous researches that three-day measles viral infection might be a significant cause for the illness. With all these research supports as foundation for a prospective study, this paper aims to give a sound explanation on how certain factors might affect the potential development of schizophrenia later in life. This study will focus on two come-at-able causative agents as parameters.The main purpose of this study is to determine if being born in severe weather, such as extreme raging or cold temperatures, or being exposed to the rubella virus in utero is linked to developing schizophrenia later in life. question HypothesisWe hypothesized that there would be an increase in the incidence of early adult onset schizophrenia among those exposed to the rubella virus in utero and those born in winter months.Literature ReviewSeveral studies have been conducted on risk factors for schizophrenia. One study examined the outcome in 70 individuals whose mothers had rubella infections during pregnancy. Rubella is known to cause severe developmental problems in exposed fetuses. These individuals risk of having schizophrenia by the time they reached the mean age of 22 years was five times higher than normal It has been proposed that environmental factors may also be important in determining risk for schizophrenia. A study d one and only(a) by Mortensen and others (1999) showed that the place and season of abide account for many more cases of schizophrenia than family history of the disease, and family history has been the best-established risk factor. The groups study found out that the risk for schizophrenia was highest for births in February and butt against and lowest for births in August and September. Another study conducted by Mortensen and others (1999) conclude that schizophrenia was positively associated with birth in late winter.On the other hand, Hultman and others (1999) emphasized the evidences shown by neuropathological researches that the aberrations caused by pathogen invasion disrupt proper conceiver development. This in turn contributes to the onset of schizophrenia that might even be developed earlier in life than expected. This proposed hypothesis can be associated with the link between obstetric complications and schizophrenia, as both are dependent on risks brought about by prenatal infections, which in turn are connected with neurodevelopment of an individual.Theoretical FrameworkThe physiological framework of this study is establish on the notion that conditions during pregnancy have an effect on the fetus psychological development, specifically, the impact of season of birth and exposure to the rubella virus.The prenatal conditions of an individual have a direct effect on the persons coming(prenominal) genetic and phenotypic gruntle. The most important contribution of the obstetric development lies on the possible alterations on the genes of th e individual. Exposure to such abnormalities has a big intervention with the normal functioning of the brain (Khasshan, 2008). This means that exposure to infections such as rubella virus has a meaningful link to schizophrenia development of the individual exposed to the pathogen in its prenatal stage.This is serves as one of the backbones of this study, as it is the foundational basis whether the link between congenital exposure to rubella and schizophrenia onset has reliable evidence.After the study which dwells more on the biological or genetic factors, the study will consider the environmental elements that can also be potential risk factors for the disorder. It has been established that the over-all make-up of an individual lies on genetic and environmental factors. The second part or backbone of the study concerns the environmental exposure effects as dictated by season of birth. This can be of importance since extreme weathers might affect a mother psychologically and physic ally, thereby creating an impact on the life inside her womb. macrocosm born on extreme baking hot and cold weather can hence be linked to the development of schizophrenia later in life of an individual (Mortensen and others, 1999).Significance and pick up for the StudyThe proposed study is important due to the health and psychological concerns of schizophrenia. Being a disorder which affects the entire lifestyle of the affected individual, it is of great substance to research about the etiology of the disease (Dean, 2003).Prenatal exposure to rubella viral infection might be a cause of the onset of schizophrenia, as well as the environmental effect of being born on an extreme season. Knowledge on these prenatal risk factors can contribute additional information on how to prevent schizophrenia development in an individual.ReferencesDean, K., Bramon, E., Murray, R., (2003).
