Effects of Media on Body Image Discussion This study was conducted to analyze the impact of media, mainly fashion magazines, on how women perceived the idealized body weight and shape as well as the impact of media on the decision to diet or initiate an exercise program. Twenty working class women were given questionnaires at different times. The exposure to fashion magazines was assessed by determining whether the participant was a high level frequency viewer of fashion magazines, viewing them once per week up to daily, or a low level frequency viewer, from never viewing them to viewing only once per month. The impact of media on feelings about weight and shape were assessed. The results were also assessed on whether participants agreed that going on a diet or initiating an exercise program was due to the impact of pictures and articles from the fashion magazines. Pie charts and graphs were done to assess the associations between levels of frequency of the media and losing weight influenced by the media. The participants were asked to assess body type by categories of thin, athletic, normal, and overweight. The outcomes were measured against the prediction that fashion magazines would have a major influence on womens body dissatisfaction, idea of perfect body shape, dieting to lose weight, and encouraging an exercise program. The results showed that fashion magazines articles and pictures had a strong influence on the perceptions of weight and body shape andShow MoreRelatedThe Effects Of Media On Body Image1484 Words Ã |Ã 6 Pages Media has developed to become omnipresent in the day to day lives of the westernized societies.

Social and economic policy decisions impact income equality, which has an effect on the health of Canadians. Those with lower incomes are directly affected while income inequality affects the health of all Canadians through weakening of social structure (Raphael, 2002). Contrary to reports of rising net worth, a new report has been released by an Ottawa-based think tank to show CanadaÃ¢â¬â¢s inequality problem. The top 10 percent of Canadians have seen their net worth grow by 42% since 2005 to 2.1 million in 2012. However, the bottom 10 percent saw their net worth shrink by 150 percent (Flavelle, 2014). With this new report, it challenges the idea that suggests Canadians are getting wealthier laterally (Flavelle, 2014). This paper will examineÃ¢â¬ ¦show more contentÃ¢â¬ ¦For example, the reduction of deaths from infectious diseases such as influenza, diphtheria and typhoid were due to improvements in general living conditions rather than medical cures (Raphael, 2002) It is hypot hesized that lifestyle differences are the reasons for the incidence of stroke, heart disease and cancer. Health and Poverty Vulnerable populations including immigrants, Aboriginal peoples, single parent families and the elderly make up a growing percentage of the lower extreme of the socioeconomic scale (Turnbull, J. Podymow T, 2002). While we are quick to consider the costs of aiding the poor, we rarely consider the costs that poverty and income inequality inflict on our society. To achieve improved health, it is critical to improve income security through good jobs, income supports and fairer taxes (Barnes et al., 2013). There are two broad strategies that focus on alleviating the effects of poverty on health: 1) directly reducing poverty and socio-economic inequality 2) intervening in pathways connecting poverty and health. These interventions have been identified as upstream and downstream. Downstream policies refer to those that have an explicit health purpose and tend to be targeted at those that are already suffering from increased health risk, while upstream refers to the wider influences on health inequalities such as income distribution, education and housing. While these approaches fall

string(29) " lack of a proper education\." Reading 1. 3 Jackall, R. (1988) Theories of decision-making process deliver to managers many essential tools such as risk and cost/benefits analysis, etc. We will write a custom essay sample on Abstracts 4 Articles Decision Making or any similar topic only for you Order Now which in tern routinizes administration. These tools cannot be used appropriately to manage of incalculable entities. The functional rationality approach is when activities precisely planned and estimated to reach some goal. This method is unlikely to be used by top managers because another important factors are involved such as ego or personal altitude. If there is no special procedure for a particular problem, manager should focus on how to turn a situation into the right way in accordance with expectations from their boss. Some managerial people cannot make their own judgments. Instead, they are looking up and looking around for someone elseÃ¢â¬â¢s opinion and finally they rely on it because of personal fears or inexperience. Another example of it is the mid-level decision-making paralysis in many American companies when a manager is trying to avoid of making a decision. In the case of inevitable decision, he or she would engage as many colleagues as possible for self-protection. Many examples of recent administrative and economic problems within American companies have showed the tendency that managers are oriented to the short-term period when making decisions. This is due to the fact that MBA programs provide tools which are focuses mostly on a short-term attitude. The second reason would be that managers are under pressure for annual, quarterly, monthly and daily results and these factors push they out of thinking about the future, even though they realise that todayÃ¢â¬â¢s minor difficulties could be tomorrowÃ¢â¬â¢s big crises. Managers are also aware of blame time and when things go wrong it is necessary to be protected from consequences. This is the reason why they gravitate towards this fear being punished rather than reflecting critically. Bureaucracy disrupts working processes into parts and the results of the work therefore disconnected with the decisions, which had been made. ManagerÃ¢â¬â¢s productivity depends on the position within management circle or their supervisors. There is no codes or systems for tracking personal responsibilities to be established. To be successful manager means to move quickly within the levels of managerial hierarchy. It protects from going into problems too deeply at every level. Example I worked for four years as an instrument engineer in the Natural gas industry in Russia. I was involved into the decision making process associated with planning resources and finances for further projects and discussions about engineering-related difficulties. Firstly, when the question was complicated and involves financial resources, I checked the parameters of equipment many times and sent the results to my boss. When I received the confirmation from him, I printed it out and managed the necessary signatures on it. I did not want to be responsible for any inconvenience because my boss has to carry out this kind of responsibility. It was extremely important for me as a lower-level manager to have the document that proves that all things are done in time and approved by middle-level manager. In case of inconveniences such as the late commissioning phase of facilities I showed the documents that all the steps were completed by me on time. Reading 4. 2 Ã Reason, J. (1990) The general view on accidentÃ¢â¬â¢s causes within complex technological systems includes theoretical framework which is not only provides the data on how dangerous factors could be combined themselves, but also where and how to predict these tendencies and take necessary measures beforehand. There are many elements of production, which are also involved into accident causation. Fallible high-level managerÃ¢â¬â¢s decisions are a major contributing factor to an increase in risk, followed by the lack of line management, which in turn causes dangerous preconditions and unsafe acts (intended and unintended). The latter are based on humanÃ¢â¬â¢s psychological characteristics and conditions and are described as a combination of both potential hazards and errors, which could cause injury or damage. Likewise, a trajectory of an opportunity includes all these factors plus safeguards and productive events. Each of these has a window of opportunity in terms of an accident incidence. Therefore damage is highly possible when this trajectory is crossing all the windows at all the stages of production. The safe operation control consists of two features Ã¢â¬â feedback and response. The theory points out that the most successful approach to manage the safety is by taken into consideration the failure types rather than the failure tokens. According to Westrum (1988) there are three groups of auctions Ã¢â¬â denial, repair and reform. The successful organization is taken actions in responding to safely data from the reform (bottom level). The fundamental distribution error relates to a personal incompetence of employee while on the other hand the fundamental surprise error is the situation when personal observation differs to a reality. Thus, taken into consideration these terms and experience from the past major accidents such as Chernobyl, the nature of a malfunction has to be considered not only as pure technical but also as socio-technical. The peopleÃ¢â¬â¢s contribution to accidents is dominating the machine failure risk. Example I investigated many serious accidents related to the natural gas transportation process. For instance, one emergency stop of the 3. 2-megawatt gas turbine was caused by the malfunction of a frequency meter. After an analysis of reports I concluded that technical maintenance of this device was conducted improperly. A responsible worker forgot to finish one procedure related to the metrology accuracy of this piece of equipment. Another example is when other gas turbine was stopped by alarm during normal working cycle. The reason for that was unplanned and uncoordinated upgrade of its automatic control system (ACS). From my point of view, the modern technology is very reliable and ACS is highly faultness but social factors as well as poor decision making are of the major reasons for emergency situations. For instance, social factors in Russia are included a low salary and the lack of a proper education. You read "Abstracts 4 Articles Decision Making" in category "Essay examples" Reading 6. Beach (1993) A descriptive Image theory focuses on peopleÃ¢â¬â¢s individual decisions rather than group ones, and it is directly opposite to prescriptive classical theory of making decisions. There are also three decision-related images (structures), which have to be possessed by a decision maker. The value i mage is based on personal principles, behavior and beliefs. These are the source for generating goals. Thus, the ultimate criteria for this is when the decision maker consider the values to be relevant. Therefore potential goals and actions, if they are inconsistent with the relevant principles, will be refused. The second image, which is called the trajectory image, includes potential goals, which have to be set and the third one, the strategic image, focuses on actions and plans that have to be performed for achieving targets. The important parts of the third image are tactic and forecast, which would be a crucial factors for monitoring a realisation progress of a particular goal. Decision-making process consists of two types of decisions such as adoption and progress which include the implementation of the compatibility and profitability tests. The compatibility test is based on both types of decisions and compares candidates to three images, whereas in contrast the profitability test relates to the adoption decision only and uses the outcome after performing the compatibility test. For instance, the compatibility test selects few candidates, who successfully crossed through a selection criteria and the profitability test therefore chooses the best candidate from the previous sorting. Another important part of the Image theory is the process of framing decisions which is the action when the goal is identified and the plan is alled back if one exists. The data from the practical research suggests that it is unlikely that the decision maker tend to change the selection criteria without changes in principles, goals and plans. Example I was involved into the process of interviewing new workers within the Natural gas industry. I had to employ personnel with sufficient technical knowledge and skills because they have to work with in hazardous areas and on potentially dangerous equipment. As a team leader I was hoping to find highly qualified workers with extensive experience for an average amount of salary. After performing several meetings and consultations with potential staff within this salary category I concluded that no one was able to pass the criteria and possess theoretical knowledge and practical achievements from previous work experience. Because of that I decided to change the working images by changing the criteria. Therefore, I focused on workers who possess theoretical knowledge with engineering ideas in complex. Although they did not have extensive experience, they satisfied basic criteria and were able to perform tasks within their role (maintenance and repair). And after this correction of principles I recruited staff for my team successfully. Reading 7. 3Ã Janis (1971) Groupthink is a way of thinking when members behave with a high level of concurrence and tend to adopt a soft line of criticism on colleagueÃ¢â¬â¢s ideas or even on every critical issue. This is why they make inhumane decisions easily with serious consequences such as the huge number of peopleÃ¢â¬â¢s deaths. The more cohesive the group, the more the risk that the decision will be proposed without the deep analysis of other choices. There are eight major symptoms of groupthink such as invulnerability, irrationality, ignorance of moral principles, stereotyped and unrealistic positions, group pressure against any critical views, memberÃ¢â¬â¢s self-censorship, unanimity tendency within a group and the mind guard which is to protect the decision from any kind of the feedback. These indicators are typical for a bad decision making process which in tern may results the inhumane decision with serious consequences. Several steps could be adopted to prevent any group from group thinking. In this case criticism should be accepted not only by members but also by a leader. Wide range of alternatives should also be taken into account as possible options. In a case of vital decisions several groups with different leaders should be established to work on the same problem. Before the final decision is made each member should discuss considerations in its unit of organisation and then provide a final response to the group. An outside expert should be invited to all meetings. One decision-maker within the group should criticise a position of the majority. In the case of consensus the group should organise the final meeting for listening and discussing any doubts against the final decision. Although these actions have also drawbacks. For instance, when growing crisis requests an immediate solution there is no time for discussions and implementing many steps for decision making. Another example might be that the risk of the leakage of vital information would significantly increases when outside specialists are involved. All in all, it seems to be clear that top priority should be given in the prevention of any policymaking unit from the group thinking. Behavioral scientists should also be involved into these processes. Example During my work in Russia a groupthink was played a crucial role because of many factors. Firstly, my colleagues were really close to each other and the companyÃ¢â¬â¢s social policy was developed for this purpose. Therefore, we spent some days playing games and sports altogether. This resulted in the number of small close-connected teams within the group. Another point is that my boss had a top role during all the process of discussion. Therefore, I had een many examples of bad decision-making. For instance, the only criticism from experienced and old colleagues was taken into account despite obvious things that were given by young professionals. Another factor is that the small teams did know how to play games within this environment and how to speculate. From my point of view, taking into consideration the long-term period, most of the final decisions were satisfactory but insufficient. It means that the p rojects were performed according to the rules and practices within timelines. But it can be clearly seen that due to the lack of criticism, for example, the total cost of the projects was increased. This way if the rules and steps of good decision practice were implemented, the cost and efficiency would significantly increase. Reading 8. 2Ã Callon (1987) The development of the technology has been explained by many social scientists using different available methods but they have not taken into account the point that the issue of the technology itself can also be represented as a sociological tool for an analysis. This also leads to the changes in understanding the dynamics of technology. There are two sociological views on the dynamic of consumption, which were developed by sociologists Touraine and Bourdieu. Touraine showed that French consumersÃ¢â¬â¢ behavior mostly dictated by large monopolies and industry, whereas in contrast Bourdieu pointed out that competition between social classes within French society taken the first place in terms of consumption of goods and services. Therefore these theories were shown by battle between engineers of two powerful French companies in the early 1970s: Electricite de France (EDF) and Renault. Despite the fact that both of them successfully proposed the concept of an electric car (VEL), the EDFÃ¢â¬â¢s theory failed because of unsolved technological difficulties related to the area of science and economy of the VEL, but the Renault did survive in the market because it focuses on not only the technological factors but also on rational views. This is the controversial result, because from the sociological point of view RenaultÃ¢â¬â¢ specialists won this battle by a chance nor by implementing genius technological ideas. This experience of engineers-sociologists is possible to use as a new methodological tool for exploring large sections of society as well as researching within the value of role of social movements in the progress of consumption. There is also a helpful tool which is named the actor network. It is the case when companyÃ¢â¬â¢s technological strategy supported by many sections of society. It describes the dynamics of society in completely different way without using sociological explanations. Firstly, in the case of implications of radical innovations within a technological sector engineers must mix technical and scientific analysis with sociology. Secondly, the actors network approach is efficient because it takes into account outside factors, which are related to common concepts of systems. Example I was responsible for implementing the concept of using compressed natural gas (CNG) as fuel for private cars and municipal buses instead of regular petrol. I was focused on the public transport such as buses because of the potential reduction of pollutions as well as the decrease of the total cost of fuel consumption. Moreover, it was easier to install the necessary equipment on buses because the government agreed to subsidise the cost of these modifications. Whereas in contrast I concluded that private car owners would not agree with this idea because the Siberian region in Russia is a large area and the number of CNG filing stations was limited to only 7. Thus, it was clear for me that using CNG fuel people could not travel between major cities which is crucial factor. This approach was based on social behavior of people and their habits. Therefore, the main target for our new policy was a municipal transport within major cities. How to cite Abstracts 4 Articles Decision Making, Essay examples

Should the CEO approve a shift to risky new technology or go with the time-tested monolithic system? by John P. Glaser F Daniel Vasconcellos after their squash game, Max Berndt drank iced tea with his board chairman, Paul Le? er. Max, a thoracic surgeon by training, was the CEO of Peachtree Healthcare. HeÃ¢â¬â¢d occupied the post for nearly 12 years. In that time the company had grown Ã¢â¬â mainly by mergers Ã¢â¬â from a single teaching hospital into a regional network of 11 large and midsize institutions, supported by ancillary clinics, physician practices, trauma centers, rehabilitation facilities, and nursing homes. Together, these entities had nearly 4,000 employed and af? liated physicians, who annually treated a million patients from throughout Georgia and beyond. The patients ranged in age from newborn to nonagenarian; represented all races, ethnicities, lifestyles, and economic conditions; and manifested every imaginable injury and disease. Paul Ã¢â¬â like other board members and some in MaxÃ¢â¬â¢s management inner circle Ã¢â¬â was applying constant pressure on Max to follow the example of others in the health care industry: Push ahead on standards and on the systems and processes to support them.

But then the iced tea ized practices could have scary patientsafety consequences, and physicians had to be free to form their own judgments about which treatments were best for which patients.

(Wallis was PeachtreeÃ¢â¬â¢s most recent addition. ) Since Max had been lunching with his chief information of? er, Candace Markovich, when the alarm came through to her PDA, he drove her over to Wallis to investigate. On the way, Candace reprised her concerns about ensuring uptime and performance quality across PeachtreeÃ¢â¬â¢s patchwork infrastructure. Ã¢â¬Å"More and more, I feel like Humphrey Bogart in The African Queen, trying to keep the blasted engine running on the boat,Ã¢â¬ she said. Ã¢â¬Å"So much of our energy and budget goes into just treading water. And the more we grow, the worse it gets. Ã¢â¬ At Wallis, Max saw cold panic on the faces of the IT staff as they rushed around trying to repair and reboot the system. Doctors and nursing supervisors stood around looking helpless or angry, sometimes a mix of both. Clinicians, having ? nally been persuaded to use information technology as a primary tool in delivering care, now depended on it to work reliably. When it didnÃ¢â¬â¢t cooperate, they Ã¢â¬â and their patients Ã¢â¬â were basically screwed. Now Max witnessed the routine nightmare that many doctors recoiled from. Talented, hardworking, highly paid people were being kept from doing their jobs by the too-unremarkable failure of what had become an indispensable tool. Although everyone in IT was working diligently to ? x the problem, diligence wasnÃ¢â¬â¢t enough to keep disgust at bay. Wherever Max looked, he saw pain.

A detailed description of the pharmacological treatments used in AlzheimerÃ¢â¬â¢s disease Introduction A detailed description of the pharmacological treatments used in AlzheimerÃ¢â¬â¢s disease IntroductionReferencesRelated Introduction The nervous system is involved in the transmission of signals for communication and for coordination of body systems. The principle cell of the nervous system is a neuron, the neuron components are a cell body, dendrites, axon, synaptic terminals and myelin sheath (not always). The cell body component of the neuron integrates signals and coordinates metabolic activities. Dendrites are the branched projections of a neuron that act to conduct the electrochemical stimulation. The axon in the neuron conducts the signal and the synaptic terminals transmit the signals. The myelin sheath is the coating on some neurons that that acts as an insulator to speed the conduction of nerve impulses, usually around only the axon of a neuron. The transmission of a nerve impulse along a neuron from one end to the other occurs as a result of chemical changes across the membrane of the neuron. The membrane of an unstimulated neuron is polarized- that is, there is a difference in electrical charge between the outside and inside of the membrane. The inside is negative with respect to the outside. Such polarization is established by maintaining an excess of sodium ions (Na+) on the outside and an excess of potassium ions (K+) on the inside. Na+/K+ pumps in the membrane actively restore the ions to the appropriate side. Other ions, such as large, negatively charged proteins and nucleic acids, reside within the cell. It is these large, negatively charged ions that contribute to the overall negative charge on the inside of the cell membrane as compared to the outside. In addition to crossing the membrane through leakage channels, ions may also cross through gated channels. Gated channels open in response to neurotransmitters, changes in membrane potential, or other stimuli. The following events characterize the transmission of a nerve impulse. Resting potential: The resting potential describes the unstimulated, polarized state of a neuron. Graded potential: A graded potential is a change in the resting potential. A graded potential occurs when the stimulus causes Na+ or K+ gated channels to open. Na+ channels open, positive sodium ions enter, and the membrane depolarizes (becomes more positive). If the stimulus opens K+ channels, then positive potassium ions exit across the membrane and the membrane hyperpolarizes (becomes more negative). Action potential: An action potential is capable of traveling long distances. If a depolarizing graded potential is sufficiently large, Na+ channels in the trigger zone open. In response, Na+ on the outside of the membrane becomes depolarized (as in a graded potential). Repolarization: In response to the inflow of Na+, K+ channels open, this time allowing K+ on the inside to rush out of the cell. The movement of K+ out of the cell causes repolarization by restoring the original membrane polarization. Soon after the K+ gates open, the Na+ gates close. Hyperpolarization: This is when K+ channels closes and more K+ has moved out of the cell. As a result, the membrane becomes hyperpolarized. Refractory period: The membrane is polarized, but the Na+ and K+ are on the wrong sides of the membrane. During this refractory period, the axon will not respond to a new stimulus. To re-establish the original distribution of these ions, the Na+ and K+ are returned to their resting potential location by Na+/K+ pumps in the cell membrane. Once these ions are returned to their resting potential the neuron is ready for another stimulus. Transmission of Nerve Impulses between Neurons: The nerve impulse (action potential) travels down the presynaptic axon towards the synapse, where it activates voltage-gated calcium channels leading to calcium influx, which triggers the simultaneous release of neurotransmitter molecules from many synaptic vesicles by fusing the membranes of the vesicles to that of the nerve terminal. The neurotransmitter molecules diffuse across the synaptic cleft, bind briefly to receptors on the postsynaptic neuron to activate them, causing physiological responses that may be excitatory or inhibitory depending on the receptor. The central nervous system (CNS) is that part of the nervous system that consists of the brain and spinal cord. The central nervous system is one of the two major divisions of the nervous system. The other is the peripheral nervous system (PNS) which is outside the brain and spinal cord. The peripheral nervous system (PNS) connects the central nervous system (CNS) to sensory organs (such as the eye and ear), other organs of the body, muscles, blood vessels and glands. The hippocampus is one of the first regions of the brain to suffer damage; memory problems and disorientation appear among the first symptoms. Damage to the hippocampus can also result from oxygen starvation (hypoxia), encephalitis, or medial temporal lobe epilepsy. People with extensive, bilateral hippocampal damage may experience anterograde amnesia- the inability to form or retain new memories. Cholinesterase is a family of enzymes that catalyze the hydrolysis of the neurotransmitter acetylcholine into choline and acetic acid, a reaction necessary to allow a cholinergic neuron to return to its resting state after activation. Cholinesterase inhibitors work by increasing levels of acetylcholine, a chemical messenger involved in memory, judgment and other thought processes. Certain brain cells release acetylcholine, which helps deliver messages to other cells. After a message reaches the receiving cell, various other chemicals, including an enzyme called acetylcholinesterase, break acetylcholine down so it can be recycled. Alzheimers disease (AD) is a slowly progressive disease of the brain that is characterized by impairment of memory and eventually by disturbances in reasoning, planning, language, and perception. Alzheimers disease is a result from an increase in the production of beta-amyloid protein in the brain that leads to nerve cell death. The only way to know for certain that someone has AD is to examine a sample of their brain tissue after death. The following changes are more common in the brain tissue of people with AD: Neurofibrillary tangles which are twisted fragments of protein within nerve cells that clog up the cell. Another change which is common in brain tissue of a patient with AD is neuritic plaques (containing beta-amyloid protein) mentioned above. This results in abnormal clusters of dead and dying nerve cells, other brain cells, and aberrant protein deposits. When nerve cells are destroyed, there is a decrease in the chemicals/electrical signal that helps nerve cells send messa ges to one another, which are called neurotransmitters. As a result, areas of the brain that normally work together become disconnected. The probability of having Alzheimers disease increases substantially after the age of 70 and may affect around 50% of persons over the age of 85. However Alzheimers disease is not a normal part of aging and is not something that certainly happens in later life, many people live to over 100 years of age and never develop Alzheimers disease. Fig 1 (alz.org/brain/images/09a.jpg) In fig 1 above is a view of how massive cell loss changes the whole brain in advanced Alzheimers disease. This illustration shows a crosswise slice through the middle of the brain between the ears. In the AlzheimerÃ¢â¬â¢s brain, the cortex shrivels up, damaging areas involved in thinking, planning and remembering. Shrinkage is especially severe in the hippocampus, an area of the cortex that plays a key role in formation of new memories. The ventricles spaces grow larger. The risks factors implicated in AlzheimerÃ¢â¬â¢s disease are age, ApoE4, DownÃ¢â¬â¢s syndrome, head injury, low education and also family history i.e. genes. The main risk factor for Alzheimers disease is increased age. As a population ages, the frequency of Alzheimers disease continues to increase. Studies show that 10% of people over 65 years of age and 50% of those over 85 years of age have Alzheimers disease. There are also genetic risk factors for Alzheimers disease. Most patients develop Alzheimers disease after age 70. However, 2%-5% of patients develop the disease in the fourth or fifth decade of life (40s or 50s). At least half of these early onset patients have inherited gene mutations associated with their Alzheimers disease. Also a child of a patient with early onset Alzheimers disease who has one of these gene mutations has a 50% risk of developing Alzheimers disease. Other risk factors for Alzheimers disease include high blood pressure (hypertension), coronary arter y disease, diabetes, and possibly elevated blood cholesterol. Individuals who have completed less than eight years of education also have an increased risk for Alzheimers disease. These factors increase the risk of Alzheimers disease, but this does not mean Alzheimers disease is necessarily expected in persons with these factors. The onset of Alzheimers disease is usually gradual, and it is slowly progressive. Problems of memory, particularly for recent events (short-term memory) are common early in the course of Alzheimers disease. Mild personality changes, such as less spontaneity, apathy, and a tendency to withdraw from social interactions, may occur early in the illness. As the disease progresses, problems in abstract thinking and in other intellectual functions develop. Further disturbances in behaviour and appearance may also be seen at this point, such as agitation, irritability and a deteriorating ability to dress appropriately. Later in the course of the disorder, affected individuals may become confused or disoriented. Eventually, patients will be unable to engage in conversation, become erratic in mood, uncooperative, and lose bladder and bowel control. In late stages of the disease, persons may become totally incapable of caring for themselves, and a result of this could be death. Those who develo p the disorder later in life more often die from other illnesses (i.e. heart disease). Fig 2 Deaths from Alzheimers disease: (alz.org/downloads/Facts_Figures_2011.pdf) From Fig 2 AlzheimerÃ¢â¬â¢s disease is the sixth-leading cause of death in the country and the only cause of death among the top 10 in the United States that cannot be prevented, cured or even slowed. From the data in the graph, death rates have declined for most major diseases while deaths from AlzheimerÃ¢â¬â¢s disease have risen 66 percent during the same period. Unfortunately, there is no cure for AD. However there are goals in treating AD, these goals are to slow the progression of the disease (although this is difficult to do), manage behaviour problems, confusion, sleep problems, and agitation, modify the home environment and support family members and other caregivers. Cholinesterase blockers are one of the main treatments of AD. Cholinesterase inhibitors are prescribed to treat symptoms related to memory, thinking, language, judgment and other thought processes. The different cholinesterase inhibitors are Donepezil, Rivastigmine, Galanthamine, Tacrine and Memantine. The three main drugs currently licensed for the treatment of AD are Donepezil, Rivastigmine and Galanthamine. Donepezil is the generic name and the brand name is Aricept. Donepezil is approved at all stages of AlzheimerÃ¢â¬â¢s disease. However the side effects of this drug are nausea, vomiting, loss of appetite and increased frequency of bowel movements. Galanthamine, brand name Razadyne, is approved for the mild to moderate stages of AD. The side effects of Galanthamine are nausea, vomiting, loss of appetite and increased frequency of bowel movements. Memantine (brand name Namenda), is approved for moderate to severe stages of AD, The side effects of this drug are headache, constipation, confusion and dizziness. Rivastigmine (brand name Exelon), approved for mild to moderate AlzheimerÃ¢â¬â¢s, the side effects of Rivastigmine are nausea, vomiting, loss of appetite and increased frequency of bowel movements. Tacrine (also known as Cognex), this was the first cholinesterase inhibitor and was approved in 1993 but is rarely prescribed today; this is because of associated side effects which i nclude possible liver damage. Cholinesterase inhibitors work by increasing levels of acetylcholine, a chemical messenger involved in memory, judgment and other thought processes. Certain brain cells release acetylcholine, which helps deliver messages to other cells. After a message reaches the receiving cell, various other chemicals, including an enzyme called acetylcholinesterase, break acetylcholine down so it can be recycled. But AlzheimerÃ¢â¬â¢s disease damages or destroys cells that produce and use acetylcholine, thereby reducing the amount available to carry messages. A cholinesterase inhibitor slows the breakdown of acetylcholine by blocking the activity of acetylcholinesterase. By maintaining acetylcholine levels, the drug may help compensate for the loss of functioning brain cells. The benefits of cholinesterase inhibitors are that people taking the cholinesterase inhibitor medications performed better on memory and thinking tests than those taking a placebo, or inactive substance. In terms of overall effect, most experts believe cholinesterase inhibitors may delay or slow worsening of symptoms for about six months to a year; although some people may benefit more dramatically or for a longer time. Namenda is approved to treat moderate-to-severe Alzheimers disease. Namenda works by a different mechanism than other Alzheimers treatments; it is thought to play a protective role in the brain by regulating the activity of a different brain chemical called glutamate. Glutamate also plays a role in learning and memory. Brain cells in people with AlzheimerÃ¢â¬â¢s disease release too much glutamate (AlzheimerÃ¢â¬â¢s Association 2007). Namenda helps regulate glutamate activity. Namenda works by blocking the receptors for the neurotransmitter glutamate. It is believed that glutamate plays an important role in the neural pathways associated with learning and memory. In brain disorders such as AlzheimerÃ¢â¬â¢s disease, overexcitation of neurons produced by abnormal levels of glutamate may be associated with neuronal cell dysfunction (resulting in cognitive and memory deficits) and eventual cell death (leading to deterioration and collapse of intellectual functioning). By selectively blocking a type of glutamate receptor (NMDA receptor) while allowing for normal neurotransmission, Namenda may help reduce the excitotoxic effects associated with abnormal transmission of glutamate. (psychatlanta.com) Namenda may have increased benefit when used with Aricept, Exelon, Razadyne, or Cognex. Memantine, a voltagegated and uncompetitive NMDA antagonist with moderate affinity, can protect neurons from excitotoxicity. It was approved for treatment of the patients with moderate to severe AD. Ã (AlzheimerÃ¢â¬â¢s Association 2007) A growing body of evidence suggest that drugs indicated for other conditions may also possess preventive efficacy for AD. Among the most promising are antioxidants, nonsteroidal, statins, certain anti hypertensive agents, alcohol, fish oil and possibly estrogen. Antioxidants have been recommended for prevention of dementia. The use of natural antioxidants may inhibit damage to the muscarinic receptors caused by free radicals, possibly by preventing or treating AD. High dietary intake of vitamins C and E lower the risk of AD. Estrogen is a weak antioxidant, it is biologically plausible that hormone replacement therapy (HRT) could protect against AD (Zandi PP et al 2002). AD is more likely to develop in a person with atherosclerotic cerebrovascular disease (Postiglione 1995). Antiatheroscleotic pharmacotherapies are used to treat atherosclerotic cerebrovascular disease, which then prevents AD from occurring (John B et al 2004). Folic acid is a AD preventer and is effective against AD. Folic acid is effective because it reduces homocysteine concentration, increased levels of homocysteine concentration increases the risk of AD. Statins is very effective at reducing the risk of AD. Statins reduce the risk of AD by reducing the cholesterol levels by interfering with the activity of enzyme. Moderate take of alcohol and intake of N-3 fatty acids reduces the risk of AD. Studies have shown that intake of N-3 fatty acids and weekly consumption of fish can decrease the risk of AD by 60 %. Pharmacological treatments of Alzheimers disease are limited. Recent observational studies have shown that use of non-steroidal anti-inflammatory drugs (NSAIDs) may protect against the development of the disease, possibly through their anti-inflammatory properties.Ã Ã (Mahyar et al 2007) The results from research which has been carried out has been varied. Caffeine can be used as a treatment in Alzheimers disease (Chuanhai et al 2009). Caffeine causes most of its biological effects via antagonizing all types of adenosine receptors (ARs), as does adenosine, exerts effects on neurons and glial cells of all brain areas. In consequence, caffeine, when acting as an AR antagonist, is doing the opposite of activation of adenosine receptors due to removal of endogenous adenosinergic tonus. Caffeine, through antagonism of ARs, affects brain functions such as sleep, cognition, learning, and memory, and modifies brain dysfunctions and diseases i.e. AlzheimerÃ¢â¬â¢s disease. (Gary W et al 2009). Studies shows that people that take regular supplements decrease the risk of AD. Many people take folate (vitamin B9), vitamin B12, and vitamin E. However, there is no strong evidence that taking these vitamins prevents AD or slows the disease once it occurs. Recent studies have shown that people believe that the herb ginkgo biloba prevents or slows the development of dementia. However, high-quality studies have failed to show that this herb lowers the chance of developing dementia. Treatment of ancillary symptoms of Alzheimer disease has improved as well. Techniques have evolved to treat depression, sleeplessness, agitation, paranoia. Also family support is a cure in its own why which gives the patient a feel good feeling to overcome AD.

Forensic psychology - Essay Example In this respect the psychologist will asses the risk of re-offending; the defendant's attitude and motivation to change; to asses the feasibility of a community based disposal rehabilitation or community service program; to assist the court to avoid the use of custody, instead using a community based disposal; and to evaluate the possible risk of defendant to harm their self and others. The forensic psychologist is required to be aware of and sensitive to the circumstances of under-represented groups in the community, for example, those who experience a mental illness. It has been indicated that the defendant is suspected of having a long-standing illness. As such, the defendant is to be shown respect, community, dignity and to be provided with unbiased and un-discriminatory services in the practices of the forensic psychologist, and in the report that the psychologist prepares for them. The forensic psychologist can develop a criminal profile of the defendant to aid in decisions about the sentencing. Using a risk and needs assessment, the psychologist can also advise the court as to the suitability of the defendant to attend rehabilitation based programs coordinated and supervised by local authorities within the prison system, if the defendant is remanded in custody.
