Analyzing Psychological Disorders
In an attempt to gain a position as a psychologist, I will be discussing schizophrenia and the disorder’s casual factors, associated symptoms, the areas of the brain it affects, and the neural basis of the disorder. I will continue on to discuss appropriate drug therapies. In addition I will also be reviewing two separate case studies, each on a different disorder. I will be examining each problem from the perspective of a bio psychologist. I will define the patient’s diagnosis at length I will relate each case to the nature-nurture theory, and talk about any helpful drug interventions or solutions for each disorder. When talking about drug intervention, it is also important to discuss the positive and negative effects that the drugs may have on the patient. Lastly I will discuss any treatment methods that have been found through research to be effective for both disorders.
Schizophrenia is defined as “a group of severe brain disorders in which people interpret reality abnormally” ("Mayo Clinic", 1998-2012). Symptoms of schizophrenia include delusions, hallucinations, incoherent speech or thought, difficulty performing everyday tasks, lack of emotion, inability to experience pleasure, and social withdrawal. It is not known exactly what causes schizophrenia, but some researchers believe that genetics and a person’s environment play a role in developing the disease. There is a 10% chance of schizophrenia occurring in a close relative of a patient with schizophrenia. Certain events may trigger schizophrenia in people who are at risk for it because of their genes. The neural basis of schizophrenia can include structural deformities of the hindbrain, forebrain and limbic system. Schizophrenia may be caused, in some measure, by an imbalance of chemicals in the brain. Neurotransmitters are the chemicals which allow messages to be sent between nerves and other nerves, organs, muscles and tissues. Large amounts of the neurotransmitter dopamine are connected with schizophrenia. Serotonin, glutamate, gamma amino butyric acid and acetylcholine are other neurotransmitters that may play a role in the development of schizophrenia. Different types of schizophrenia include paranoid, catatonic, disorganized, and childhood schizophrenia, as well as schizoid personality disorder, schizoaffective disorder, and schizotypal personality disorder. Schizophrenia is a chronic condition, meaning a person with this disease requires lifelong treatment. Schizophrenia can be treated with anti-psychotics. They alter the balance of chemicals in the brain and can help regulate symptoms. These medications are normally beneficial, but they can have side effects. Some drugs that may be used include Abilify, Zyprexa, Seroquel, and Risperdal. Some negative side effects of these antipsychotics include weight gain, diabetes, and high blood pressure. Families and society are affected by schizophrenia too. Many people with schizophrenia have difficulty holding a job or caring for themselves, so they rely on others for help. Therapy may be effective for many people with schizophrenia. Behavioral methods, such as social skills training, can be utilized to enhance social and work functioning. Job training and relationship-building programs are also important. Family of a person with schizophrenia ought to be informed about the disorder and offered support. Programs that have outreach and community support services can aid those who lack family and social support. Often, symptoms improve with medication. Still, some people might have difficulty functioning and are in jeopardy of having recurrent episodes, particularly in the early phases of the disease. The average life expectancy of people with the disorder is 12 to 15 years less than those without.
