Describe and evaluate one or more biological explanations of schizophrenia Research has shown that schizophrenia is heredity and can runs in families. This suggests that genes play a significant role. The closer the genetic relationship the more likely the people are to share the disorder. Evidence from family studies by Gottesman showed that when bothparent are schizophrenic then there is a 46% chance of the child getting it‚ however‚ if only one parent had it‚ it dropped to 17%. This suggests

There are two main biological theories which explain the assumed causes of schizophrenia: Genetic and Dopamine Hypothesis. Research by Mikaywa et al has found that there must be a genetic explanation of schizophrenia due to the fact that concordance rates for environmental causes are not 100%. Also Mikaywa noticed that schizophrenia runs in the family‚ meaning there must be something other than environmental causes‚ causing the disorder. What Mikaywa studied was DNA from human families who were

Describe and evaluate at least two biological treatments for schizophrenia Biological treatments arise from the medical model of abnormal behaviour‚ which considers mental disorder to be an illness of disease resulting from underlying biological factors. Most people with schizophrenia receive some form of drug therapy. Drug therapy is the most common treatment‚ using antipsychotic drugs. Antipsychotic drugs aims to help patient function as well as possible and increasing patient’s feelings of well

Outline and evaluate psychological explanations for schizophrenia (24) One psychological explanation of SZ was put forward by Bateson et al (1956) who looked at childhood as a base for developing SZ‚ for example the interactions children have with their mothers. His explanation‚ the Double Bind theory‚ states that schizophrenia can occur due to conflicting messages given from parents to their children‚ for example when a parent expresses care but does so in a critical way. This means that the child

Outline and evaluate psychological explanations of schizophrenia (24 marks) Brown and Birley studied stressful life events in the role of relapse in schizophrenics. They found that 50% of people experience a stressful life event e.g. death‚ relationship break-up‚ job loss etc. in the 3 weeks prior to a schizophrenic episode. A control sample reported a low and unchanging level of stressful life events over the same period. However not all evidence supports the role of life events. For example‚

Describe two explanations of schizophrenia and evaluate these explanations (9 and 16 marks) Two explanations of schizophrenia are the biological perspective and the psychological perspective. The biological perspective involves genetic factors that influence schizophrenia‚ however the psychological perspective involves environmental factors in which you learn the behaviour of a schizophrenic. The first explanation is the biological perspective‚ it has two subtypes‚ these are biochemical and
Premium Dopamine Schizophrenia Psychology
According to the biological approach the mental disorder Schizophrenia will have an underlying physical cause such as imbalance of hormones‚ brain damage and infection. There is strong evidence that biological factors influence the presence of Schizophrenia. There are certain chemical abnormalities that can be observed in people suffering from schizophrenia. Post-mortems on schizophrenics have shown unusually high levels of dopamine. Dopamine is a brain chemical that increases the sensitivity of

dysfunctional behaviour which could be a genetic cause or a malfunction of brain structures. Although it is seen as the most common explanation for schizophrenia due to the use of drug therapy‚ it would be deterministic and reductionist to explain schizophrenia only with the biological approach since there are other numerous factors such as the ones related to the cognitive explanation or other environmental causes. Also‚ even within the biological approach‚ there are various different biological factors that

Describe and evaluate biological explanations of OCD (10 marks) The biological approach as an explanation of OCD believes that the disorder is caused by a fault in our body‚ either through genes‚ hormones‚ the brain‚ or neurotransmitters‚ therefore suggesting that OCD is caused by our nature‚ rather than our upbringing. This means that since we are born with the body we have‚ if we have OCD‚ it is innate within us. One biological explanation for OCD is the genetic explanation. The genetic
