Introduction

Transfer-Encoding: chunked ´╗┐Biological approach (12 marks) The biological approach suggests psychological disorders have an organic or physical cause and tend to include brain injury, infection, neurotransmitters and genetics. Mental disorders are related to the physical structure and function of the brain; for example, neurotransmitters are thought to have involvement in conditions such as schizophrenias, bi-polar and depression. High levels of dopamine is linked with schizophrenia, low levels of serotonin is linked with depression and high serotonin is linked to Bi-polar. Treatments from the biological approach focusses on the organic of physical causes of abnormality, these include drug treatments and ECT (Electro convulsive therapy).

The patient may have 3-6 treatments per week for several weeks. ECT is very effective and has a 70% improvement on depression. In addition, it has been questioned if the patient can they give informed consent if they are sectioned (are they emotionally capable).
