Life events Stress can have a major effect on the risk somebody is at from schizophrenia. We are unsure of why and how stress can increase the risk of schizophrenia, however many psychologists believe that the high arousal from stress can trigger changes in neurotransmitters, which then leads to the higher risk.
People with schizophrenia often illustrate bizarre behavior accompanied with distorted mind, disorganized perceptions, or withdrawn emotions. Their neurocognitive deficits aggravate over time Seidman et al. Today many researchers have come to recognize that aspects of individuals such as their histories, social relationships, lifestyles, personalities, mental processes, and biological processes should be considered in a full conceptualization of risk factors for mental disorders.
Based on this model, the biopsychosocial theories have been developed to study mental disorder including schizophrenia. Brains of People with Schizophrenia Two hundred years ago phrenologists raised concerns of localization of functions in the brain.
Scientists in the past have identified localization of function on the cortex Hergenhahn, Research showed that schizophrenia and other mental disorders may be related to dysfunctions or abnormal structures of localized units of the brain.
Based on studies of abnormal brains during last ten years, scientists connected schizophrenia, especially cases dominated by negative symptoms, to structural abnormalities of the brain.
From brain images, researchers identified that schizophrenic patients usually have enlarged ventricles, the brain cavities that contain cerebrospinal fluid Comer, Recent studies also linked schizophrenia to abnormalities of the hippocampus, amygdala, and thalamus, among other brain structures.
In a study on cortical thickness, gray matter volume, and white matter diffusivity and anisotropy in schizophrenia, Murakami et al.
Another research by Pinkham showed that schizophrenia is associated with aberrant brain responses in the neural network involved in cognition-emotion interaction. These findings point to neurophysiological alterations in brain networks associated with cognitive control over emotion processing, which may underlie impairments in many aspects of goal-directed behavior in people with schizophrenia.
Even though psychologists today can associate schizophrenia with disturbances in identifiable brain regions and the chemicals located there, the research of schizophrenia should not be restricted simply to these regions and chemicals Toates, The Genetic Factors In genetic research, scientists found that a biological predisposition to schizophrenia could be inherited by some people who might develop this disorder later when they experience extreme stress, usually during late adolescence or early adulthood.
Genetic Factors are often viewed on the basis of principles of the diathesis stress perspective. According to Joober, Boksa, Benkelfat, and Rouleauresearchers have found neither major genes that cause schizophrenia nor a gross neuropathological signature of schizophrenia.
However, recent findings in genetic epidemiological research demonstrated additive and interactive genes could only place small effects from each but coherently manifest the genetic vulnerability for schizophrenia. To fully understand the genetics of schizophrenia, Joober et al.
Taking advantage of salient progress in neuroscience in recent years, scientists have used neuroimaging to study the neurobiological processes that convey the mental disorder risk from the genes to the complex phenotypes.
In a study of schizophrenic genetics related to neurotransmitters, Hirvonen and Hietala revealed that people with a risk of schizophrenia share neurotransmitter abnormalities with changes in the dopamine system.
Molecular imaging studies have shown that potential intermediate phenotypes that carry the risk for schizophrenia include increased striatal presynaptic synthesis, increased striatal D2 receptors, and increased cortical D1 receptors.
Solli and Barbosa Da Silva further explained that environmental exposures may influence the expression of genes by affecting a number of neurotransmitter systems. Environmental factors can also trigger schizophrenic behavior by disturbing brain functions of hypothalamic-pituitary-adrenal axis, the autonomic nervous system, and the immune system.
According to Richard and Brahmclinical studies on schizophrenic patients showed that genetic, environmental, and neurobiological factors are related to immunologic influences on schizophrenia. Therefore, the onset of schizophrenia may be prevented or controlled by manipulation of environmental factors to protect and enhance the immune system for individuals with high risk of this disease.
Among environmental factors, unhealthy communication patterns within family have been thought to contribute to psychological problems and mental disorders. Past researches attempted to make connections between particular communication patterns and pathological outcomes in the case of schizophrenia; however these factors had been over-emphasized.
For example, early studies introduced theories that schizophrenic symptoms with a child were caused by a family environment where a cold, authoritarian mother dominated an ineffectual father.kgb answers» Science & Technology» How is schizophrenia explained by the biological, psychological and sociocultural views.
Biologically, schizophrenia is a result of somatic (physical) factors in the brain or body. Similarly, in schizophrenia and other mental illness, the psychiatrists, psychologists and researchers, and research studies are increasingly suggesting while a biological or genetic factor the base cause of schizophrenia - we are beginning to understand that the psychological, emotional and social environment that children grow up in have a vast impact on their mental health - and yes - risk for mental illness.
A psychological reason for schizophrenia may include a variety of environmental factors such as malnutrition (which could also be considered a biological factor), issues during birth, and stress issues during childhood or the present time.
The current experiments examine mental health clinicians’ beliefs about biological, psychological, and environmental bases of the DSM-IV-TR mental disorders and the consequences of those causal beliefs for judging treatment effectiveness.
Scientists intend to explain mental disorders by considering more than one kind of cause at a time. Using the biopsychosocial model, researchers study biological, psychological, and social factors and their interactions that affect schizophrenic pathology and onset.
