The phenomenon of bipolar affective disorder has b Essay een a mystery sincethe 16th century. History has shown that this affliction can appear inalmost anyone. Even the great painter Vincent Van Gogh is believed tohave had bipolar disorder. It is clear that in our society many peoplelive with bipolar disorder; however, despite the abundance of peoplesuffering from the it, we are still waiting for definite explanationsfor the causes and cure. The one fact of which we are painfully awareis that bipolar disorder severely undermines its victims ability toobtain and maintain social and occupational success. Because bipolardisorder has such debilitating symptoms, it is imperative that we remainvigilant in the quest for explanations of its causes and treatment. Affective disorders are characterized by a smorgasbord of symptomsthat can be broken into manic and depressive episodes. The depressiveepisodes are characterized by intense feelings of sadness and despairthat can become feelings of hopelessness and helplessness. Some of thesymptoms of a d epressive episode include anhedonia, disturbances insleep and appetite, psycomoter retardation, loss of energy, feelings of worthlessness, guilt, difficulty thinking, indecision, and recurrentthoughts of death and suicide (Hollandsworth, Jr. 1990 ). The manicepisodes are characterized by elevated or irritable mood, increasedenergy, decreased need for sleep, poor judgment and insight, and oftenreckless or irresponsible behavior (Hollandsworth, Jr. 1990 ). Bipolaraffective disorder affects approximately one percent of the population(approximately three million people) in the United States. It ispresented by both males and females. Bipolar disorder involves episodesof mania and depression. These episodes may alternate with profounddepressions characterized by a pervasive sadness, almost inability tomove, hopelessness, and disturbances in appetite, sleep, inconcentrations and driving.

Mostcommonly, individuals with manic episodes experience a period ofdepression. Symptoms include elated, expansive, or irritable mood,hyperactivity, pressure of speech, flight of ideas, inflated selfesteem, decreased need for sleep, distractibility, and excessiveinvolvement in reckless activities (Hollandsworth, Jr. 1990 ). Rarestsymptoms were periods of loss of all interest and retardation oragitation (Weisman, 1991). As the National Depressive and Manic Depressive Association (MDMDA)has demonstrated, bipolar disorder can create substantial developmentaldelays, marital and family disruptions, occupational setbacks, andfinancial disasters. This devastating disease causes disruptions offamilies, loss of jobs and millions of dollars in cost to society. Manytimes bipolar patients report that the depressions are longer andincrease in frequency as the individual ages. Many times bipolar statesand psychotic states are misdiagnosed as schizophrenia. Speech patternshelp distinguish between the two disorders (Lish, 1994). The onset of Bipolar disorder usually occurs between the ages of 20and 30 years of age, with a second peak in the mid-forties for women. Atypical bipolar patient may experience eight to ten episodes in theirlifetime. However, those who have rapid cycling may experience moreepisodes of mania and depression that succeed each other without aperiod of remission (DSM III-R). The three stages of mania begin with hypomania, in which patientsreport that they are energetic, extroverted and assertive (Hirschfeld,1995). The hypomania state has led observers to feel that bipolarpatients are addicted to their mania. Hypomania progresses into maniaand the transition is marked by loss of judgment (Hirschfeld, 1995). Often, euphoric grandiose characteristics are displayed, and paranoid orirritable characteristics begin to manifest. The third stage of maniais evident when the patient experiences delusions with often paranoidthemes. Speech is generally rapid and hyperactive behavior manifestssometimes associated with violence (Hirschfeld, 1995). When both manic and depressive symptoms occur at the same time itis called a mixed episode. Those afflicted are a special risk becausethere is a combination of hopelessness, agitation, and anxiety thatmakes them feel like they could jump out of their skin(Hirschfeld,1995). Up to 50% of all patients with mania have a mixture of depressedmoods. Patients report feeling dysphoric, depressed, and unhappy; yet,they exhibit the energy associated with mania. Rapid cycling mania isanother presentation of bipolar disorder. Mania may be present withfour or more distinct episodes within a 12 month period. There is nowevidence to suggest that sometimes rapid cycling may be a transientmanifestation of the bipolar disorder. This form of the diseaseexhibits more episodes of mania and depression than bipolar. .uaef73d3cbf224d60511e53566e0ebcf7 , .uaef73d3cbf224d60511e53566e0ebcf7 .postImageUrl , .uaef73d3cbf224d60511e53566e0ebcf7 .centered-text-area { min-height: 80px; position: relative; } .uaef73d3cbf224d60511e53566e0ebcf7 , .uaef73d3cbf224d60511e53566e0ebcf7:hover , .uaef73d3cbf224d60511e53566e0ebcf7:visited , .uaef73d3cbf224d60511e53566e0ebcf7:active { border:0!important; } .uaef73d3cbf224d60511e53566e0ebcf7 .clearfix:after { content: ""; display: table; clear: both; } .uaef73d3cbf224d60511e53566e0ebcf7 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uaef73d3cbf224d60511e53566e0ebcf7:active , .uaef73d3cbf224d60511e53566e0ebcf7:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uaef73d3cbf224d60511e53566e0ebcf7 .centered-text-area { width: 100%; position: relative ; } .uaef73d3cbf224d60511e53566e0ebcf7 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uaef73d3cbf224d60511e53566e0ebcf7 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uaef73d3cbf224d60511e53566e0ebcf7 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uaef73d3cbf224d60511e53566e0ebcf7:hover .ctaButton { background-color: #34495E!important; } .uaef73d3cbf224d60511e53566e0ebcf7 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uaef73d3cbf224d60511e53566e0ebcf7 .uaef73d3cbf224d60511e53566e0ebcf7-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uaef73d3cbf224d60511e53566e0ebcf7:after { content: ""; display: block; clear: both; } READ: Petrified Man By Eudora Welty EssayLithium has been the primary treatment of bipolar disorder sinceits introduction in the 1960s. It is main function is to stabilize thecycling characteristic of bipolar disorder. In four controlled studiesby F. K. Goodwin and K. R. Jamison, the overall response rate forbipolar subjects treated with Lithium was 78% (1990). Lithium is alsothe primary drug used for long- term maintenance of bipolar disorder. In a majority of bipolar patients, it lessens the duration, frequency,and severity of the episodes of both mania and depression. Unfortunately, as many as 40% of bipolar patients are eitherunresponsive to lithium or can not tolerate the side effects. Some ofthe side effects include thirst, weight gain, nausea, diarrhea, andedema. Patients who are unresponsive to lithium treatment are oftenthose who experience dysphoric mania, mixed states, or rapid cyclingbipolar disorder. One of the problems associated with lithium is the fact thelong-term lithium treatment has been associated with decreased thyroidfunctioning in patients with bipolar disorder. Preliminary evidencealso suggest that hypothyroidism may actually lead to rapid-cycling(Bauer et al., 1990). Another problem associated with the use oflithium is experienced by pregnant women. Its use during pregnancy hasbeen associated with birth defects, particularly Ebsteins anomaly. Based on current data, the risk of a child with Ebsteins anomaly beingborn to a mother who took lithium during her first trimester ofpregnancy is approximately 1 in 8,000, or 2.5 times that of the generalpopulation (Jacobson et al., 1992). There are other effective treatments for bipolar disorder that areused in cases where the patients cannot tolerate lithium or have beenunresponsive to it in the past.The American Psychiatric Associationsguidelines suggest the next line of treatment to be Anticonvulsantdrugs such as valproate and carbamazepine. These drugs are useful asantimanic agents, especially in those patients with mixed states. Bothof these medications can be used in combination with lithium or incombination with each other. Valproate is especially helpful forpatients who are lithium noncompliant, experience rapid-cycling, or havecomorbid alcohol or drug abuse. Neuroleptics such as haloperidol or chlorpromazine have also beenused to help stabilize manic patients who are highly agitated orpsychotic. Use of these drugs is often necessary because the responseto them are rapid, but there are risks involved in their use. Becauseof the often severe side effects, Benzodiazepines are often used intheir place. Benzodiazepines can achieve the same results asNeuroleptics for most patients in terms of rapid control of agitationand excitement, without the severe side effects. Antidepressants such as the selective serotonin reuptake inhibitors(SSRIs) fluovamine and amitriptyline have also been used by somedoctors as treatment for bipolar disorder. A double-blind study by M. Gasperini, F. Gatti, L. Bellini, R.Anniverno, and E. Smeraldi showedthat fluvoxamine and amitriptyline are highly effective treatments forbipolar patients experiencing depressive episodes (1992). This study iscontroversial however, because conflicting research shows that SSRIsand other antidepressants can actually precipitate manic episodes. Mostdoctors can see the usefulness of antidepressants when used inconjunction with mood stabilizing medications such as lithium. In addition to the mentioned medical treatments of bipolardisorder, there are several other options available to bipolar patients,most of which are used in conjunction with medicine. One such treatmentis light therapy. One study compared the response to light therapy ofbipolar patients with that of unipolar patients. Patients were free ofpsychotropic and hypnotic medications for at least one month beforetreatment. Bipolar patients in this study showed an average of 90.3%improvement in their depressive symptoms, with no incidence of mania orhypomania. They all continued to use light therapy, and all showed asustained positive response at a three month follow-up (Hopkins andGelenberg, 1994). Another study involved a four week treatment ofbright morning light treatment for patients with seasonal affectivedisorder and bipolar patients. This study found a statisticallysignificant decrement in depressive symptoms, with the maximumantidepressant effect of light not being reached until week four (Baur,Kurtz, Rubin, and Markus, 1994). Hypomanic symptoms were experienced by36% of bipolar patients in this study. Predominant hypomanic symptomsincluded racing thoughts, deceased sleep and irritability. Surprisingly, one-third of controls also developed symptoms such asthose mentioned above. Regardless of the explanation of the emergenceof hypomanic symptoms in undiagnosed controls, it is evident from thisstudy that light treatment may be associated with the observedsymptoms. Based on the results, careful professional monitoring duringlight treatment is necessary, even for those without a history of majormood disorders. .u733f6033deabf05e434ccd9a11e56213 , .u733f6033deabf05e434ccd9a11e56213 .postImageUrl , .u733f6033deabf05e434ccd9a11e56213 .centered-text-area { min-height: 80px; position: relative; } .u733f6033deabf05e434ccd9a11e56213 , .u733f6033deabf05e434ccd9a11e56213:hover , .u733f6033deabf05e434ccd9a11e56213:visited , .u733f6033deabf05e434ccd9a11e56213:active { border:0!important; } .u733f6033deabf05e434ccd9a11e56213 .clearfix:after { content: ""; display: table; clear: both; } .u733f6033deabf05e434ccd9a11e56213 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u733f6033deabf05e434ccd9a11e56213:active , .u733f6033deabf05e434ccd9a11e56213:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u733f6033deabf05e434ccd9a11e56213 .centered-text-area { width: 100%; position: relative ; } .u733f6033deabf05e434ccd9a11e56213 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u733f6033deabf05e434ccd9a11e56213 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u733f6033deabf05e434ccd9a11e56213 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u733f6033deabf05e434ccd9a11e56213:hover .ctaButton { background-color: #34495E!important; } .u733f6033deabf05e434ccd9a11e56213 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u733f6033deabf05e434ccd9a11e56213 .u733f6033deabf05e434ccd9a11e56213-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u733f6033deabf05e434ccd9a11e56213:after { content: ""; display: block; clear: both; } READ: Nutrition vs. sport performance EssayAnother popular treatment for bipolar disorder iselectro-convulsive shock therapy. ECT is the preferred treatment forseverely manic pregnant patients and patients who are homicidal,psychotic, catatonic, medically compromised, or severely suicidal. Inone study, researchers found marked improvement in 78% of patientstreated with ECT, compared to 62% of patients treated only with lithiumand 37% of patients who received neither, ECT or lithium (Black et al.,1987). A final type of therapy that I found is outpatient grouppsychotherapy. According to Dr. John Graves, spokesperson for TheNational Depressive and Manic Depressive Association has c alledattention to the value of support groups, and challenged mental healthprofessionals to take a more serious look at group therapy for thebipolar population. Research shows that group participation may help increase lithiumcompliance, decrease denial regarding the illness, and increaseawareness of both external and internal stress factors leading to manicand depressive episodes. Group therapy for patients with bipolardisorders responds to the need for support and reinforcement ofmedication management, and the need for education and support for theinterpersonal difficulties that arise during the course of the disorder.

Barriers in Business Communication

Barriers in Business Communication Communication is essentially the process by which information is transferred from the source to the desired actual recipient(s) through a medium. The medium is the route by which the message is transmitted. Once the receiver of the information gets the message they are bound to give a feedback or act to the message given.Advertising We will write a custom research paper sample on Barriers in Business Communication specifically for you for only $16.05 $11/page Learn More There are various forms of communication within a work place and each organization will use the form of communication that suits them best. Whichever form of communication used is not an issue so long as the information gets to the right recipient and at the correct time. Business communication is therefore an important tool in the workplace. This is because of the fact that organizations are essentially made up of people who have to communicate to each other so as to ensure smooth running of the operations and fulfillment of organizational goals and objectives. Due to this, communication is among the top management principles of any organization (Kondrat, 2009, p.1). Through communication all the other systems of the organization can be well monitored and run. It is true to say that communication is the backbone of any organization since without communication the top management will not be able to delegate duties, the workers will not be in a position to know what they are obliged to do in time, changes in the organization will not be known and also the organization will not be able to know what their competitors are doing. Communication Barriers The workplace environment is made up of a range of factors some of which affect the communication systems in an organization. These factors include personal factors of an individual, those that bring visual problems by hindering the message and last but not least the auditory factors. Visual factors will comprise of distance, lightening, weather conditions, the visibility and the angle of viewing. A clear example is when there is not enough lighting in a room, the people inside will not be able to communicate effectively. Auditory factors will involve factors such as noise, echoing or the distance between the sender and receiver. A good example is people working in factories that produce a lot of noise during their operations. Other barriers of communication in the work place include; Conflict In cases where the superiors are not in good terms with the subordinates then communication becomes a problem. The workers will not be ready to listen to whatever is being said since they have conflicted in other grounds. When this happens it is always advisable that peace is made as early as possible so as not to affect the operations of the organization.Advertising Looking for research paper on business communication? Let's see if we can help you! Get your first paper with 15% OFF Learn More Poor Timing Good timing of the message to be communicated is always very important. In cases where the message reaches the recipients earlier or later than desired it may not be well perceived. For example if the top management issues a notice whose deadline is very near, the workers may not welcome it as they may not have adequate time to achieve it because of their duties. Attitude The attitude or behavior of either the giver or receiver of the information may affect communication (Kondrat, 2009, p.1). If the receiver of the massage is not willing to receive the message then communication will not take place. In the same way the sender of the message may not be willing to send the message, for example if the workers are not ready to voice out their side of the story then the management may not be able to know their problems hence ineffective communication. Conclusion From the above discussion, communication is thus very essential in the organization and should be properly manag ed if at all the organization is to be successful. The main objective of communication is to make sure that the information is correctly delivered and feedback given. By understanding the possible factors that may affect communication in an organization, it is possible to take measures to counteract them hence making communication effective. Since in most cases in an organization the senders of the messages are the top management they should therefore make sure that the information they send will be well received by the employees. They should get appropriate channels of communication and also good timing of the message. For example calling a parade just before the employees have had their lunch will be a waste of time as no one will be ready to listen to you. In such a case the management ought to be clever enough such that the give incentives just before communicating to their subordinates as way of encouraging them to listen. It is for the same reason that the sitting allowance is given for meetings. Reference List Kondrat, A. (2009). Effective Communication in the Workplace. Web.

Artificial Intelligence Research Paper Example | Topics and Well Written Essays - 1500 words

Artificial Intelligence - Research Paper Example This study seeks to understand the behaviour in humans and animals, and the hope to reproduce it after extensive analysis. As such, AI has become a significant subject in computer science owing to numerous studies on intelligent behaviour through computer simulation. The simulations are geared towards influencing similar intelligent traits on to agents that perceive their environment and takes appropriate action to ensure success. The discipline is subdivided into various fields depending on their area of study and application of their product. These fields include statistical analysis, psychology, cognition, biology among others. However, the different fields often fail to communicate with each other owing to social, cultural and ethical factors, which limit the success of artificial intelligence. Although AI research does not aim at wholly imitating human intelligence, evidence exists that suggests human intelligence is a key tacit heuristic to AI researchers and strongly affects A I studies (Prudkov, 2010). In this regard, intelligence is described as a set of properties of mind, which include the ability to plan, solve problems and reason out depending on the presented stimuli. The replication of intelligence based on human and animal behaviour produces intelligent agents, which have the capacity to respond to the environment in natural way. For instance, artificial intelligence in machines coupled with algorithms, enables them to solve complex problems in humanistic fashion. In essence, AI seeks to produce useful machines that are guided by human-like intelligence and behavioural traits. The history of artificial intelligence dates back to mid-1950s where researchers wrote programs that allowed computers to solve algebraic expressions, confirming logical theorems as well as speak English. This application AI holds similar characteristics with the methods used to study cognition in experimental psychology. These methods include the measurement of IQ levels, which requires that the thinking, reasoning and learning skills be gauged to establish the level of perceptual skills.AI and psychology disciplines have naturally interacted with each other to borrow concepts while criticising the weaknesses of the other. However, it is important that psychologist and AI researchers work together as cognitive scientists in order to understand the human cognition and its incorporation into intelligent agents. The success of such research has seen the development of advanced and highly effective technological systems with industrial and social application. These technologies have illustrated the potential within AI research by developing sophisticated methods of solving problems through robust diagnostic and planning systems. Artificial intelligence is housed in sophisticated hardware systems that have evolved over time based on technological advances. Historically, the hardware system was based on vacuum tubes as established with the production of th e first generation computers. Over the years, technological advance have seen the vacuum tubes replaced by microchips to build smaller and faster hardware components for artificial intelligence. The hardware is controlled be a set of instruction in the form of software and applications, which perform designated tasks and yield results. The interaction between the hardware and software
