Discuss Explanations For Schizophrenia

Discuss explanations for dementia praecox. It has been suggested that schizophrenia is workd by the imbalance of the neurotransmitter dopamine. This theory is wherefore known as the Dopamine Hypothesis. The dopamine supposition bring together schizophrenia to oversensitive dopamine receptors in certain(p) areas of the brain. It has been suggested that schizophrenia is not caused by the overproduction of dopamine, but rather in that location are either as well many or too sensitive receptor sites. It has also been suggested that there may be a fault in the re-uptake sites where the dopamine is restored in the pre-synaptic neuron. Evidence to prove this hypothesis is mainly displace from medicate studies, amphetamines in particular(a) because they prevent the breakdown of dopamine and so increase dopamine levels in the synapse. One force fulfil of the dopamine hypothesis is that anti-psychotic drugs, which block the dopamine receptors in the brain, are put up to all eviate the symptoms of schizophrenia. This supports the dopamine hypothesis by proving that dopamine actively involved in the cause of schizophrenic symptoms. A impuissance how perpetually, is that dopamine is not the only neurotransmitter link up to schizophrenia. clozapine is 1 of the most effective drugs in treating schizophrenia.

Clozapine in particular has a major impact on the serotonin carcass rather than the dopamine system. This therefore suggests that certain levels of serotonin or oversensitive receptor sites could also cause schizophrenia. Another strength is that there is increasingly convincing severalise to support this hypothesis. With ever advancing technology, PET sca ns have allowed researchers to check out do! pamine action at law with more the true than with previous efforts, measuring dopamine performance within fellate products. Arguably, one of the biggest weakness with the dopamine hypothesis is that it fails to provide a complete explanation. The antipsychotic drugs take some(prenominal) weeks to reduce symptoms despite the occurrence that the drugs begin to...If you want to bestow a full essay, set it on our website: OrderEssay.net
