Describe and evaluate two possible causes of Schizophrenia and two treatments This essay will be evaluating two possible causes of schizophrenia and two treatments. Schizophrenia is one of the psychoses. The term covers a whole range of mental disorder, including thought disorder, where language and thinking are grossly disturbed; delusions, for example that some external force ('God', 'the government' etc.) is directing the person's behaviour; and hallucinations, where imaginary voices and figures are heard and seen. Most experts now believe that schizophrenia is caused by biological and environmental factors. The biological factor coming from a predisposition in the brain, that is most likely inherited from certain genes. This predisposition can happen from as early as when a child is in the womb. Environmental stressors can lead to subtle alterations in the brain, which can make a person more susceptible to schizophrenia. Environmental stressors in early childhood can further damage the brain increasing the risk of schizophrenia. Environmental stressors for example, social stress, isolation during childhood and drug abuse can act as a catalyst for schizophrenia. Experts are now saying schizophrenia and other mental illness is caused by a combination of biological, psychological and social factors. ...read more.


have a 10% chance of developing schizophrenia. A person born in an urban environment has a 50% chance of developing schizophrenia. A child born from a mother who has Rubella has about a 500% increased risk of schizophrenia. Other causes of schizophrenia through environmental causes are, bereavement (death of a spouse or close family member), as well as flood, the unwantedness of a child (i.e. if the pregnancy was unexpected and undesired at that time), and maternal depression, can all be considered to be different types of high stress situations for the mother and child. One treatment for schizophrenia is anti-psychotic drugs. Chloropromazine acts like a powerful sedative for severely disturbed psychotic patients. The drug reduces the level of activity, stabilize mood and reduce hallucinations and paranoid feelings. The drug has allowed many people suffering from mental illness to live with in a community. The effect of the drug do not last long, and wear off within a few days. The short-term effect of this drug, results in the drug being taken regularly. Most drugs do come with side effects, and chloropromazine is no exception. Its side effects include blurred vision, fainting fits and a lack of energy. ...read more.


Recent imaging studies suggest that there may be increased dopamine release in response to amphetamine administration compared to controls. Some studies indicate increased uptake of L-dopa in parts of the striatum, but some do not. The potential confounding effects of factors associated with dopamine release-such as movement, arousal, attention, stress, and smoking-have rarely been examined, and prior medication use may also have influenced results in some studies. Comparable research on other psychiatric conditions associated with increased arousal, stress, and physical activity is sparse. Research on dopamine concentrations in postmortem brain tissue, on homovanillic acid concentrations, and on dopamine receptors has been negative or inconclusive. Therefore, the idea that the symptoms of psychosis or schizophrenia are caused by the overactivity of dopamine is not supported by current evidence. http://www.informaworld.com/smpp/content~content=a912030792~db=all~jumptype=rss To conclude I have described and evaluated two causes and two treatments for schizophrenia. I have found out that both forms of therapies have their faults, but they also have their benefits. For schizophrenics who kill, I can feel for them, not compassion but just an understanding that the majority of them do not actually know any better, from what I have studied and have found out. With medical science and therapies advancing everyday, we might hope that one day we find a way we can help schizophrenics a lot more then we already do. ...read more.
