Outline and Evaluate Biological Treatments for Schizophrenia
Outline and Evaluate Biological Treatments for Schizophrenia.
The meaning of Schizophrenia is the loss of contact with reality also known as split-mind. It shouldn’t be thought of as one disorder as there are several sub-types such as; paranoia, catatonic, disorganised, and undifferentiated; they all have different symptoms. It is a disorder which is estimated at 1% of the population and is more common in males, lower social classes and African-Caribbean’s living in the U.K.
Schizophrenia is characterised by a profound disruption of cognition and emotion, which affects a person’s language, thought, perception and sense of self. The assumptions of biological therapies are that schizophrenia can be treated physically and internally, though the use of medication and drugs etc.
Conventional antipsychotic drugs are an example of a biological therapy for the treatment of schizophrenia. They reduce the effects of dopamine (a neurotransmitter that helps control the brains reward and pleasure centres) to reduce symptoms of schizophrenia. Dopamine antagonists bind to dopamine receptors but do not stimulate them, blocking their action. Chlorpromazine (a synthetic drug used as a tranquilizer and sedative) can eliminate some of the positive symptoms of schizophrenia such as hallucinations and delusions. The effectiveness of these drugs in reducing symptoms led to the development of the dopamine hypotheses (argues that schizophrenia is based on over-activity of synapses that depend on dopamine.)
Another example of a biological therapy for the treatment of schizophrenia is atypical antipsychotic drugs. These drugs act on the dopamine system and also block serotonin receptors in the brain (known as the happy hormone because the level or lack of greatly influences moods and sense of well-being). They help by temporarily blocking D2 receptors and then rapidly dissociating to allow normal dopamine transmission. They are responsible for lowering side effects more than conventional

    In the article “What is Schizophrenia” by Lindsey Konkel (Web), discuss the main facts on what schizophrenia is, what causes this disorder and how it affect people throughout their daily lives. Schizophrenia is a brain disorder that causes difficulty for individuals to separate what is realistic or unrealistic, such as a person’s thoughts, feelings, and/or their actions. Schizophrenia is a disorder that can affect an individual’s day-to-day performance, however; this disorder can be controlled by using the proper treatments.…

    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 the brain cells that promote the individual’s awareness of events around her or him when in danger or aroused and when under stress. If, however, the individual’s level of brain activity is already highly aroused, then the effects of additional dopamine activity may trigger the onset of a psychotic state, such as schizophrenia. Seeman (1987) reviewed a number of studies and found a 60-110 density increase in dopamine receptor cells in schizophrenics compared to controls. Wong (1986) found twice the increase in dopamine receptor cells in untreated schizophrenics compared to normal controls and untreated schizophrenics. These show that the much higher levels of dopamine activity in the brain of a schizophrenic may cause or trigger the disease. However where these biological changes do occur they could be the result of the schizophrenia rather than the cause, or linked in ways we have yet to discover.…

    Researchers believe that dopamine plays an important part in schizophrenia. The goal of conventional antipsychotic drug therapy is to reduce the amount of dopamine, or the amount of dopamine receptor sites. They are dopamine antagonists in that they bind dopamine receptors and blocking their action.…

    The dopamine hypothesis says that schizophrenia is caused by an increased reaction to dopamine in the brain. This could be because there is too much of the hormone dopamine in the brain, or conversely because there is an abnormally high number of dopamine receptors in the brain. This model says the excess sensitivity to dopamine results in the brain causes the symptoms of schizophrenia.…

    The development and use of Antipsychotic drugs to treat schizophrenia support the dopamine hypothesis. The drugs work by blocking activity of dopamine and have been shown to alleviate symptoms of schizophrenia, such as hallucinations, delusions and thinking problems associated with the disorder. This is because by reducing dopamine activity helps to maintain a constant level in guiding attention, leading to a decrease in key schizophrenic symptoms of hallucinations and delusions because they can be caused by being overly attentive. Statistics increase the reliability of the biological explanation of the dopamine hypothesis for explaining schizophrenia; as they show Antipsychotics have a 60% success rate. Therefore, this shows a link between high levels of dopamine activity and schizophrenia, as antipsychotics work by blocking the dopamine activity. This has led to more…

    One biological therapy is the use of typical anti-psychotic drugs, such as Chlorpromazine. The main aim of this drug is to treat schizophrenia by reducing the amount of dopamine in the brain. This is because high levels of dopamine are thought to cause schizophrenia, therefore by reducing the amount of dopamine, the symptoms of schizophrenia should reduce. Typical anti-psychotic drugs bind to dopamine receptors (particularly the D2 receptor) and block their action. These drugs are thought to be very effective at reducing symptoms such as delusions and hallucinations.…

    Antipsychotic medication is an effective way of treating severe forms of Schizophrenia. There are two types medication used: Conventional antipsychotic drugs are dopamine antagonists, which means they attach to dopamine receptors but do not stimulate them. By reducing stimulation in the brain, medication such as Chlorpromazine can eliminate the positive symptoms of Schizophrenia. Atypical antipsychotic drugs also work on the dopamine system but instead are believed to block serotonin receptors as well. Kapur and Remington (2001) suggested that the drugs do not involve serotonin but only dopamine receptors. They help by only temporarily occupying the dopamine receptors and then quickly dissociating to allow normal function of dopamine. It is this characteristic that is thought to be responsible for the lower levels of side effects compared to conventional drugs.…

    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 disorder.…

    The Medical Model (MM) of treatment proposes that the causes of schizophrenia are physical (biochemistry/neuroanatomy) therefore, the treatment should also be physical. The MM recommends direct manipulation of biological process to treat schizophrenia. Anti-psychotic (AP) drugs are designed to reduce the effects of the neurotransmitters which are believed to be the cause. There are two forms of AP drugs: conventional and atypical. Conventional AP drugs, such as phenothiazine, can reduce the amount of available dopamine receptors by blocking them; drugs such as chlorpromazine reduce acute positive symptoms such as…

    There are much several possible medication that can be subscribed to treat symptoms, such as “antipsychotic, antidepressant, and anticonvulsant drugs” that are used to help prevent delusions and hallucinations. According to textbook Conventional antipsychotic medication and second generation antipsychotic are used to reduce anxiety and agitation as well as to prevent hallucinations and delusional behavior (Graham, 2014, p. 168-169). The conventional antipsychotic includes “haloperidol and Chlorpromazine “which are very effective and fast-acting medication against the anxiety and severe agitation. However, a study indicates that they are more likely to have a significant side effect such as tremors, drowsiness, and weight gain” Graham 2014,…
