Psychological Disorder, Causes and Treatments

In the UK about one quarter of the population will experience some kind of psychological disorder in the course of a year. These disorders include, but are not limited to Anorexia, Social Phobia, Agoraphobia, Schizophrenia, Amnesia and Depression. Many of these disorders have therapies developed from psychological theories to treat the disorders. A number of factors can influence whether a person develops a disorder, it could be due to heredity factors, environmental factors or a combination of both (Mental Health Foundation, 2014). This essay will focus on the disorders Depression, Schizophrenia and Social Phobia. Each disorder will be examined in terms of its symptoms and features, then each will be analysed to determine the possible causes of these disorders. Finally, it will explore the treatments available for the three disorders and evaluate how effective the treatments are Depression is a mood disorder that can cause a person to have severe feelings of despondency and dejection along with a loss of interest in daily life. A person’s behaviour, along with their feelings and thoughts can be affected by depression. This then can lead to a variety of physical problems for a person as well as also affecting their emotions. (Mayo Clinic, 2014). Depression can cause a number of psychological symptoms including a continuous low mood along with feelings of tearfulness, irritability and anxiousness. It can also cause a person to suffer from a number of physical symptoms such as constipation, low sex drive, a lack of energy and disturbed sleeping patterns. Depression is a disorder that affects people of all ages, backgrounds, lifestyle and nationality. Up to 20% of people will experience symptoms of depression at some point in their lives, with the average age of first onset being 25-29. It is estimated that 10x the amount of people suffer with depression now than they did in 1945 (NHS Choices, 2014). Many researchers have found evidence that depressive illnesses can run in families. However, until recently it was not known whether a person inherited a susceptibility for depression or if environmental factors were actually the cause. Research has found that a person can inherit a vulnerability to depression. So if a person has a close relative that suffers or has suffered from clinical depression, then that person may inherit a tendency to develop depression themselves. Genes can determine which illnesses a person may be vulnerable to at some point in their life. If a person has a parent or sibling who has had clinical depression that person could be 1.5 to 3 times more likely to develop the condition than those who do not have a relative with the condition (NHS Choices, 2011). However, some researchers suggest that genetics only predispose people to certain conditions, they need an environmental trigger to develop. The Diathesis- Stress Model is based on the assumption that individual with a genetic predisposition to depression need an environmental trigger to actually develop the disorder. This trigger could be a stressful life event such as a parents divorce or a death of a close friend or family member. The model suggests that the greater a person’s inherent vulnerability for developing depression, the less environmental stress will be required to cause them to become depressed (Mental Help, 2007). Schizophrenia is a long term mental health condition in which people interpret reality abnormally. It causes a range of different psychological symptoms including changes in behaviour, hallucinations and delusions which then can lead to muddled thoughts. It can also cause a person to suffer from physical symptoms such as; overly acute senses, inability to express emotion through their face, inexact motor skills and facial dyskinesia. Schizophrenia affects just 1% of the population and is most often diagnosed between the ages of 15 and 35. Both men and women are equally affected....
