Analyzing Psychological Disorders Essay

Schizophrenia is a disorder that is characterized by a broken thought process and poor emotional responses. Typical symptoms of this disorder include delusions, paranoia, hallucinations, social dysfunctions,

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

In chapter 15 of Exploring Psychology, the author discuss the basics of psychological disorders. Within this assignment, the psychological disorder of my choosing is Dissociative Identity Disorder. The commonality of the disorder is rare. Although we’ve disassociated ourselves in some form or the other with our ability to daydream, Dissociative Identity Disorder (DID) is more severe and is usually linked to trauma. Formerly the disorder was known as Multiple Personality Disorder (MPD). Individuals who suffer from this disorder usually have more than one aspect of themselves or personalities, whom he or she is completely unaware of. Sufferers of the disorder have to deal with a variety of symptoms such as memory loss, depression, anxiety, hallucinations, black-outs, impulsiveness, and perception of being detached from the self. The severity of the trauma is usually extreme, repetitive, and long-term. The individual may have an extensive history of physical, emotional, and/or sexual abuse.

The term ‘schizophrenia' covers a group of serious psychotic disorders characterised by a loss of contact with reality. It comes from two Greek words: schiz meaning ‘split' and phren meaning ‘mind'. DSM IV (1994) estimate that the occurrence rate of schizophrenia ranges from 0.2%-2.0% worldwide. There are two main explanations of schizophrenia: the biological explanations and the psychological explanations. In this essay I will critically consider the biological explanations. These include genetics, neurochemistry, brain structure and evolution.

Schizophrenia is a psychotic disorder characterized by distorted thinking, impaired emotional responses, poor interpersonal skills and a distortion of reality. It is the most common of psychotic disorders that, in most countries around the world, affects around 1 per cent of the population. In terms of explanations for the disorder, two central types of explanations arise – psychological explanations and biological explanations. Whereas psychological explanations tend to focus on cognitive, emotional and environmental factors that may cause the disorder, biological explanations tend to focus on genetic, biochemical and neuro-anatomical factors as the cause of the

Per the DSM-5 a diagnosis of schizophrenia requires the presence of the following symptoms: delusions of thoughts, prominent and lasting hallucinations, incoherent or marked loosening associations, catatonic behavior, and flat or grossly inappropriate affect (APA, 2013). If using the DSM-5 classification these characteristics must be present on a continuous basis for at least six months prior to diagnosis.

Currently there are no cures for schizophrenia, but the symptoms are helped by taking antipsychotic medication. The symptoms experienced by those with schizophrenia are grouped in to three categories: negative symptoms, positive symptoms, and cognitive symptoms (Regier 1993, p.92). The positive symptoms include, hallucinations, delusions, unusual or dysfunctional ways of thinking, agitated body movements. Negative symptoms include, flat affect, reduced pleasure in everyday life, difficulty sustaining tasks, and reduced speech. Cognitive symptoms include, disruption in executive functioning and working memory, as well as reduced ability to concentrate. The etiology of schizophrenia is still debated by psychologists and neuroscientists, but factors such as neuroanatomy, and environmental influences are believed to play a key role. A genetic predisposition to schizophrenia has been established by researchers, but it remains unclear what causes the phenotype to be expressed. The most agreed upon cause of schizophrenia refers to the diathesis-stress model, which explains schizophrenia as a response to an individual’s allostatic load becoming too much for the brain to cope with. Another popular explanation amongst neuroscientists is the dopamine

Schizophrenia is a severe brain disorder that affects the cognitive, behavioral, and emotional parts of the brain. The symptoms include hallucinations, delusions, disorganized speech and cationic behavior, and negative symptoms. The DSM-5 states that symptoms delusions, hallucinations, and disorganized speech must be present for at least one month in order for one to be diagnosed with schizophrenia. Also, the DSM-5 mentions that the symptoms have to be ongoing for at least six months to be schizophrenic. Hallucinations include hearing voices, smelling distinct odors, and seeing unrealistic figures. The disorganized speech or behavior of the affected person includes those saying random words and moving excessively with an agitation which

Schizophrenia is a chronic brain disorder that affects more than one percent of the population. When schizophrenia is active, symptoms can include delusions, hallucinations, trouble with thinking and concentration, and lack of motivation. However, when these symptoms are treated properly, a large portion of those diagnosed will greatly improve over time.

Two Biological Explanations of Schizophrenia There are many biological explanations of schizophrenia. In this essay I will concentrate on the genetic explanation and biochemical explanation of the disorder. There are many studies that look in to genetics and the link to schizophrenia. This is dues to an original finding that schizophrenia runs in families and therefore suggests that genes are responsible for the disorder.

Biological, psychological, and sociocultural viewpoints have been developed in an attempt to explain schizophrenia. All three viewpoints point out various factors that may contribute to the development of the disorder.

Personality disorders are very defined and recognized in today’s society. The Diagnostic and Statistical Manual of Mental Disorders (DSM) published by the American Psychiatric Association provides common language and standards classifying mental disorders. The DSM is used by many people in varying disciplines in the USA as well as many other countries. In times past, people with disorders may have been outcast from a community or even persecuted. However, in our current culture the pendulum has swung in the other direction. It almost seems that there is a trend to explain all behavior by a mental disorder. This results in needing to disprove that certain people are not displaying a disorder, rather acting within a normal human emotion or

There are times when people are plagued with thoughts, behaviors or emotions that will inhibit them from normal behavior. These are known as psychological disorders. These disorders come in many forms but all will have large effects on a person’s life.

In some people's cases, Schizophrenia appears suddenly and without warning. But for most it comes slowly, with subtle warning signs and a gradual decline in functioning long before the first severe episode. “In the early phases of Schizophrenia people often seem eccentric, unmotivated, emotionless, and reclusive (Helpguide.org).” They may isolate themselves and not want to participate in daily activities such as playing with their children, going outside, or getting off the couch. They abandon their hobbies and they do not do well in their jobs. “The most common early warning signs of Schizophrenia include: social withdrawal, hostility or suspiciousness, deterioration of personal hygiene, having a flat and expressionless gaze, the inability to cry or express joy, inappropriate laughter or crying, depression, oversleeping or insomnia, odd or irrational statements, forgetfulness or the inability to concentrate, extreme reaction to criticism, and or strange use of words or way of speaking (Helpguide.org).” There are five types of symptoms of Schizophrenia. Positive is a symptom that involves having hallucinations or delusions. Negative is when one shows no emotion or flat behavior. Avolation is when a person shows little interest in whatever they are doing. Cognitive behavior is when you have disorganized speech or memory loss. Catatonic behavior is considered poor functioning such as your voluntary muscles
