Introduction There are primary neurological brain abnormalities in individuals with schizophrenia. According to Fusar-Poli (2009), schizophrenia is delineated by prefrontal activity and elevated striatal dopaminergic functions. These elevations in striatal dopamine activity and prefrontal cortical dysfunctions (Fusar-Poli, 2009). Along with other abnormalities in white matter as well as, having been observed in the right superior frontal gyrus, left middle frontal gyrus, bilateral parahippocampal
the cause of schizophrenia as referenced in the PowerPoint are Dopamine, Glutamate, Brain Abnormalities, and Nature vs. Nurture / More than one cause. 1. Dopamine Definition Dopamine is a neurotransmitter. It is one of the chemicals that is responsible for transmitting signals between the neurons of the brain. However, very few of those neurons actually produce dopamine. (psychologytoday.com) Theory The main theory concerning dopamine is that too much it can result in schizophrenia. Antipsychotic
attempt to explain schizophrenia. All three viewpoints point out various factors that may contribute to the development of the disorder. 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
Schizophrenia Pathophysiology Schizophrenia is a very complex disorder, and it is said that it involves irregulation of multiple pathways. It is believed that schizophrenics have an abnormal level of dopamine in their brains. Serotonin, GABA (gamma-aminobutyric acid) and glutamate may also play a role. Deficits in acetylcholine muscarinic receptors have been identified in individuals with schizophrenia. “Evidence from genetic, post-mortem and animal studies over the past decade has identified a
Schizophrenia is a heterogeneous illness that may involve several pathophysiological gender differences. For men and women incidence risk peaks between 20-29 years of age, and women also have a second risk peak between 30–39 years of age. Negative symptoms including low motivation and withdrawal are more frequent in men and appear up to six years before diagnosis (Hafner, 2005; Hafner et al., 1993; Morgan et al., 2008). Women exhibit greater levels of depression and positive symptoms including sexual
In the search for the etiology of schizophrenia, several possibilities have been investigated, including psychodynamic, autoimmune, and genetic, but two have been long pitted against each other: neurodevelopmental and neurodegenerative. While there is evidence for both processes, current research is more supportive of a neurodevelopmental etiology. However, schizophrenia will likely not be explained by a single process. Since the current study did not include longitudinal studies, it is difficult
Schizophrenia: its Aetiology Lesley Stevens and Ian Rodin justified the need of acquisition to the mental disorders’ aetiology in their book “Psychiatry”. They pointed out the fact that psychiatrists need to be familiar with the contribution of a particular disorder in order to make a more confident in the diagnosis. Knowing the aetiology of psychotic disorder is as important as the diagnosis. For the simple reason that psychotic disorders do not have particular tests that can be made for diagnosis;
Schizophrenia What is schizophrenia? Schizophrenia is a psychiatric disorder characterized by hallucinations, delusions, disorganized thought, cognitive impairment, and mood symptoms. Hallucinations may include hearing voices (auditory hallucinations) or seeing people (visual hallucinations) that are not actually present. Patient also often have “negative” findings such as decreased energy, flat affect, and a lack of interest. These symptoms must typically be present for at least 6 months and
Schizophrenia as a Biological Disorder As well as the biological approaches there are physiological, psychological and environmental explanations. New theories of schizophrenia are constantly being developed each having their own advantages and disadvantages. How do we know however, which one is correct? The biological explanation suggests that schizophrenia is produced by an unfortunate combination of genes or is due to physical problems in the brain. Researchers
The causes, cures and intellectual comprehension in schizophrenia patients remains unknown. Scientists have discovered that schizophrenia is a severe condition that develops by a combination of biological, environmental, and unforeseen factors. Since this condition effects no more than two percent of the population, it is challenging to find an adequate sample size for assessments and further study. People suffering from schizophrenia are incapable of determining reality and show a wide array of
