SCH consists of a variety of symptoms and is tops(predicate) complex. It is believed to be a series of separate disorders that have been bleed under this diagnosis. Currently there is not unitary import up that can completely explain the beget of why schizophrenic disorder happens, however there are galore(postnominal) approaches from both biological and psychological areas that attempt to explain it. genius of the biological theories of dementia praecox is the Dopamine Hypothesis. This is a biochemical write up that suggests the disorder is ca aimd by an excess of the neurotransmitter dopamine in the head word. The main(prenominal) evidence for this has move up from studies on both keep and post-mortem brains of sufferers from schizophrenia, and also from observations made during drug therapies. This possibilit y acts as one explanation of how the genetic theory may work, in that certain(a) genes that are inherited could cause an increase in dopamine production or sense organ density. Originally, studies of the brain were carried expose post-mortem; however with an improvement in technology it is now executable to generate images of living brains. One of the graduation post-mortem studies was carried out by Owen et al.

(1978) who found that schizophrenic brains had a high(prenominal) density of dopamine receptors than expected. This was seat up by Snyder (1976) and also Inversens (1979) findings of higher levels of dopamine than normal. It could be debated th! at perhaps as these findings were from deceased patients that the results do not guard what is occurring in living brains Further deport was presented as the use of PET scans became possible. This technique allowed researchers to see and unwrap different areas of the brain using radioactive glucose. Studies such as by Wong et al. (1986) who provided support for previous investigations, as results showed that in the brains of live...If you deprivation to get a full essay, order it on our website: OrderCustomPaper.com
