Outline and evaluate the biological/medical model of abnormality( 12 marks ) This explanation of abnormality maintains that mental disorders are due to a physical illness or disease as the result of brain damage which can happen through things like brain tumours or the effects of poisoning due to alcohol or drug abuse. Infections such as syphilis can damage the brain too, producing symptoms such as delusions of grandeur. Disorders e.g. depression, are thought, by some people, to be the result of biochemical changes which cause failure in the neurotransmitters carrying messages to the brain, possibly because of life stress, infections or genetic inheritance. Genetic research has shown that, possibly, some people inherit genes which put them at risk of developing a mental disorder but this is only significant, as yet, in schizophrenia and manic depression. ( 125 words ) Many psychologists believe that this explanation takes away the idea that it is the patient’s fault resulting in others being more sympathetic but Szasz(1972) argued that people are still afraid of it because it is difficult to understand and there is still a certain stigma attached to it. However, if mental illness is physical then it can be treated with drugs e. g. antidepressants, which are easy to take and can act quickly. But there is a problem with this treatment because it does not deal with why the disorder has occurred, only the symptoms, which reappear if drug treatment stops and therefore patients become dependent on them. Also, patients often report that the side effects can be worse than the disorder itself. Alternative forms of treatment are psychosurgery or ECT, but both of these are only used in extreme cases as they are ethically very controversial and can result in problems e.g. memory loss. Although research about how chemicals affect the brain shows they could be responsible for the development of disorders, it is not easy to distinguish whether they are the cause or the result of the disorder. Genetic research has shown that there could be a connection between genes and mental disorders e.g. schizophrenia but there is a limited connection with other disorders. Genetics can be helpful in a physical disorder but in mental disorders there always seems to be some environmental influences which is a trigger and therefore it can cause unnecessary anxiety in the relatives of a diagnosed patient. Ultimately, there could be a danger of so much knowledge of genes leading to ‘ designing ‘ a baby. This model also fails to take into account that even if there is some kind of of illness or disease causing the disorder, there might be other factors in the person’s life contributing to the problem as well.
