Discuss explanations for schizophrenia. It has been suggested that schizophrenia is workd by the imbalance of the neurotransmitter dopamine. This theory is hence known as the dopamine Hypothesis. The dopamine supposition concern schizophrenia to oversensitive dopamine sensory receptors in received atomic number 18as of the brain. It has been suggested that schizophrenia is not caused by the overrun of dopamine, but preferably in that location are either as well many or too sensitive receptor sites. It has also been suggested that there whitethorn be a gaolbreak in the re-up harbor sites where the dopamine is restored in the pre-synaptic neuron. Evidence to parent this hypothesis is mainly worn from medicate studies, amphetamines in particular(a) because they hold open the breakdown of dopamine and so increase dopamine levels in the synapse. One force twist of the dopamine hypothesis is that anti-psychotic drugs, which gag law the dopamine receptors in the brain, are put up to remedy the symptoms of schizophrenia. This supports the dopamine hypothesis by proving that dopamine actively intricate in the cause of schizoid symptoms. A impuissance how perpetually, is that dopamine is not the only neurotransmitter link up to schizophrenia. clozapine is 1 of the well-nigh 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 endorse to support this hypothesis. With ever forward-moving technology, PET scans have allowed researchers to investigate dopamine action at law with more true statement than with previous efforts, measuring dopamine performance within turn back 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 accompaniment that the drugs begin to...If you want to confab a full essay, crop it on our website: Ordercustompaper.com
