Biological Therapies Used for Schizophrenia Aqa

Describe and evaluate at least both biological therapies for schizophrenia (8+16) One biological therapy for speaking schizophrenia is the use of drugs that meet on neurotransmitter pathways in synapses in the brain.

Typical antipsychotics fall the effects of dopamine and so reduce the symptoms of schizophrenia. They are dopamine antagonists in that they bind to dopamine receptors (particularly the D2 receptors) provided do not stimulate them, hence block their action. By reducing stimulation of the dopamine system in the brain, antipsychotic drugs such as chlorpromazine can disdain the h tout ensembleucinations and delusions experienced by people with schizophrenia. Many studies that hand evaluated the strong suit of typical antipsychotic medication defecate done so by comparing relapse ordinate with th ose on a placebo. For example, a review by Davis et al (1980) found a evidential difference in financial value of relapse rates between treatment and placebo in every read reviewed, thus demonstrating the therapeutic effectiveness of these drugs.

However, a more recent depth psychology of that study by Ross and Read has declare oneselfed that its results were misleading: as all those studied, including those who took placebos, were on antipsychotics in the beginning this study began, it was, rather than a study comparing treat to non-treatment, a comparison between keep treatment and pull away treatment. Ross and Read suggest a significant proportion of the relapses in the placebo gr oup can be explained by these withdrawal sym! ptoms, go forth the conclusions drawn by Davis discredited. In terms of appropriateness, critics have similarly pointed to the development of tardive dyskinesia- uncontrollable movements of the lips, tongue, face, hand and feet- in 30% of patients taking typical antipsychotics, with only 25% of these cases treatable. Some suggest that given this side effect,...If you want to beat up a full essay, order it on our website: OrderEssay.net
