Investigating whether MMR causes Autism.

Extracts from this document...

Introduction

Introduction: In this Case Study I am going to be investigating whether MMR causes Autism. I will also be putting forward the arguments for and against it. I am going to be using various diagrams and scientific information which you will need to know in order to understand this case study. I will also be talking about what MMR vaccines and Autism and whether they have a link or not. I will also go on to present my views on whether I think there is a link between MMR and Autism. I will include an evaluation and bibliography, which will state where I got my information from and how reliable the information is. I have chosen this topic because I believe it is quite fascinating, along with the media hype which has gone with it, the controversies which have arisen as a result, and also as I am very interested to find out whether MMR causes Autism. The reason being the MMR vaccine is given to most children and it would be very interesting to know if these children are at risk of having Autism. I personally believe there is no link between MMR vaccinations and Autism. To make sure I am not biased in any way is will be using reasonable point to argue for and against the statement "Does MMR cause Autism". What is Immunization and how does it work? Immunization is a process which makes someone immune to an infectious disease/organism. ...read more.

Communication and language problems are also most important in autism. Approximately 50% of autistic people do not develop meaningful communicative language and most autistic people have problems with other forms of communication. Verbal autistic youngsters are frequently echolalia and cannot engage in social conversations. Non-verbal youngsters have difficulty understanding or being understood and consequently often retreat from interactions with others. Play is impaired in most autistic youngsters, lacking the social and creative aspects generally seen in non-handicapped children. The third primary characteristic of those with autism is their restricted range of behaviours, and interests. Lower functioning autistic people frequently engage in repetitive bodily movements, self stimulatory behaviours and sometimes even self abuse. Their play patterns are restricted and repetitive. Higher-level autistic people may focus on some topics that are narrow and generally uninteresting to others for example bus or train timetables, the telephone directory memorising sequences of numbers. The symptoms of Autism can be noticed. During late infancy, parents or caregivers often start noticing signs of indifference or even aversion in their child when showing affection or cuddling their child. They also often observe other symptoms such as: a lack of eye contact, no facial receptiveness or socially directed smiles and notice that their child fails to respond to their voice or the voices of its siblings. The first clear signs of abnormality become apparent when a child's language skills lack speech development or are much delayed. As infants and toddlers grow older, these skills do not appear to progress. ...read more.

Conclusion

* The study authors conclude that: "These data provide evidence against a causal association between MMR vaccination and the risk of autism". Conclusion: In conclusion, in support of my hypothesis, I still believe that there is no link between the MMR vaccination and Autism. Although it is shown that there is link between MMR vaccinations and Autism, there is no clear scientific explanation behind the claims. There is definitely no link between these two factors, the reason being the combination of the three virus strains overloading the body's immune system has nothing to do with Autism because Autism is a genetic disease. Therefore it wouldn't make any difference if the immune system was overloaded or not, because either way the child would have Autism. Also nobody it quiet sure about what the exact cause of Autism is, therefore it would be wrong to say that the MMR vaccine causes Autism. Although it could also be pointed out that there is a link between the MMR vaccine and Autism, this would include the graph which shows that straight after the MMR vaccine was given the number of Autism cases increased. Claims have also been made that giving a vaccine which contains mumps, measles and rubella could overload the immune system, which could then cause bowel cancer. Furthermore it is important to understand that there was only small concern with the link of MMR and Autism, but the research of the scientists around the world has outweighed the small concern and proved that there is no connection between MMR vaccinations and Autism. ...read more.
