Intellectual Disabilities and its categories Essay

Intellectual Disabilities and its categories - Essay Example The outcome is severe personality disorder followed by lack of communicational skills. Such patients possess attitude problem like speech disorder, mental disorder and are often tended towards what we call as 'roller coaster of thoughts'. However, the dilemma remains that this lifelong disease is responsible for conducting many suicidal behaviors, mood instabilities and frustration causing serious crime and is still not given that much attention as it supposed to be given. Siever et al describes Schizotypal disability as a disorder, which shares common phenomenological, genetic, biologic, outcome, and treatment response characteristics with more severely ill chronic schizophrenic patients. (Siever & Davis) However, at the same time, they are freer from the multiple artifacts that potentially confound research in schizophrenia including the effects of long-term and usually ongoing medication treatment, multiple hospitalizations or institutionalization, and prolonged functional impairment secondary to chronic psychosis and social deterioration. (Siever & Davis) Genetic Factors: Studies have shown that that if one person has schizophrenia, the chance for another person also sharing the disorder depends on the degree of genetic relatedness between them. For example if one twin has schizophrenia, the chance that the co-twin will also have schizophrenia is around 18% if they are non identical twins but 48% if they are identical twins as identical twins share 100% of their genes. (Rapee, 2001:22) Neurotransmitters/ Disconnection Syndrome: The biological models of schizophrenia emphasize neurochemical dysregulation or anatomical changes in the brain. The most widely disseminated and thoroughly developed biological theories include the neurotransmitter model. (Beebe, 2003) The cause of Schizophrenia is followed by one of the most widely accepted theory named "Dopamine Theory". This hypothesis states that schizophrenia can be understood in cognitive terms, as a failure of functional integration within the brain. Functional integration refers to the interactions of functionally specialised systems (i.e., populations of neurons, cortical areas and sub-areas) that are required for adaptive sensorimotor integration, perceptual synthesis and cognition. (Friston, 2002) According to this theory, most of the symptoms of schizophrenia are the result of having excessive levels of dopamine, especially in the mesolimbic pathways of the brain. (Carson & Sanislow, 1993) Several sources support this theory. First many of the drugs that are used to treat schizophrenia seem to work primarily by blocking certain dopamine receptors in the brain. Second certain drugs that have been found to increase levels of dopamine in the brain also produce symptoms that are very similar to those found in schizophrenia. An appropriate example is the

Improving Education with IT - Research Paper Example d to have a significant impact on the world of education and literacy and carries promising prospects for improving the status of education in the modern world through the gamut of facilities it offers to mankind. Before the coming of the internet, the education curriculum was kept restricted to the subjects and topics in which either the teachers enjoyed expertise or for which the institute’s library provided resources. But today, with the advent of the World Wide Web, the horizons of education have spread manifold. The students no longer have to confine their learning to the resources supplied by the library or remain dependent on the teachers’ lectures. They can choose their own subject of interest and gain endless knowledge and information on the same with just one click. Online courses have become increasingly popular nowadays, wherein the students get an access to customised curriculum, at any time and from any place of their choice. This is especially useful for the students who stay at remote places devoid of proper educational institutes and channels. Traditionally the students would blindly follow and memorise theories, models and formulae dictated by the books and teachers, at times without even understanding them. But now, with the help of IT tools like spread sheets and concept maps, they can not only understand concepts better, but also cross-check and verify them if needed. Education is the most important armour that equips a person to face the series of challenges posed by life and to successfully conquer the hardships that one comes across during the journey of life. It is that ingredient of our life that remains constantly with us throughout our life and helps us to steer through the odds of life. It is not just a part of one’s academic or professional life, but also an equally vital component of one’s personal and social life. Education shapes up the way in which we perceive the society and interpret the world. Hence the advancements and
