Biological Causes Of Autism Essay

Autism is not an immune-mediated disease. There is no evidence of immune activation or inflammatory lesions in people with autism. No studies have compared the incidence of autism in vaccinated, unvaccinated, or alternatively vaccinated children. Twenty epidemiologic studies have shown that neither thimerosal or MMR vaccine causes autism. There have been studies in many countries by different people who have tried multiple statistical methods. A meta-analysis of ten studies involving more than 1.2 million children reaffirms that vaccines don’t cause autism. Immunization was associated with decreased risk that children would develop autism, a possibility that’s strongest with the measles-mumps-rubella

Many believe the measles mumps-rubella (MMR) vaccine triggers autism spectrum disorder in some children. Many Hollywood celebrities in the acting community that have birthed children that suffer from autism spectrum disorder have concluded that this is how their child developed autism. These celebrities being very vocal about this link between vaccinations and autism spectrum disorders and have in turn influenced the increase in many ordinary middle-class parents refraining from getting the medically recommended vaccinations for their children. The medical community has done extensive research on this theory. However, to this date no reliable study shows a link between autism spectrum disorder and the measles mumps-rubella vaccine. In fact, the medical community have continued to recommend childhood vaccinations and continue to emphasis the danger of a non vaccinated child catching and spreading serious diseases like whooping cough (pertussis), measles and mumps (Mayo Clinic, 2012).

In the article, “Vaccines Cause Autism,” Michael Snyder, an attorney and writer, attempts to convince parents of young children that autism is directly linked to childhood vaccinations. He claims that numerous toxins, including thimerosal, are present in vaccines that are forced into the bloodstream, later causing neurological and brain damage to children. He says that autism has risen by 78 percent over the past decade, and that 1/88 children in the US have an autistic disorder. Snyder believes that most autistic individuals start out completely normal, and that the vaccinations they are given are harming them. He blames the pharmaceutical companies for being too

Much evidence supports a link to vaccinations to autism. There are many studies that cite the early and intense immunization of children has led to the autism epidemic.

“Autism is a disorder characterized by severe difficulties in social interaction and communication and with unusual behaviors.” (Dr. David Pauls 2003). This disorder is assumed to be caused by genetics, environmental toxins and/or prenatal care. (Harvard Medical School 2013). Social behaviors/interactions affected by Autism is the ability to process learning, communication and family/peer relationships. Autism is a disorder in which its cause makes it impossible to prevent and it takes a toll on its victim’s everyday life tasks.

One of the most controversial stories in today’s medicine is between autism and vaccinations. Autism is a disorder that makes it difficult for people to communicate with others and form relationships with them. It has been thought that vaccinations that children receive at an early age cause autism. Autism has become more prevalent over the years and scientists are still unsure how the disorder has come about. Some parents have taken it upon themselves to not vaccinate their children because they believe it will cause their child to become autistic. The real question is do vaccines really cause autism and if so which vaccine is it?

The purpose of this research is to find whether there is an actual link between childhood vaccines (MMR) and autism. The research also aimed to dispute the notion that MMR vaccines caused autism.

Countless deem that the definite reason for autism is not the dead or live virus found in vaccines but the derivatives’ within them. “Exposure to thimerosal, a mercury-containing preservative that is used in vaccines and immunoglobulin preparations, has been hypothesized to be associated with increased risk of autism spectrum disorder (ASD)” (Price, et al., 2010). This continues to remain merely speculation. The Centers for Disease Control research analysis’ do not corroborate toxicity of these preservatives. Mercury produces verified detrimental effects on children when absorbed in the gastrointestinal tract. Vaccinations are not absorbed in the GI tract and are instead absorbed in the muscles or subcutaneous tissues, depending on the route of injection.

Throughout research done on the possible link between vaccines and autism, there have been three hypotheses: (1) the combination MMR vaccine causes autism by damaging the intestinal lining, which allows the entrance of encephalopathic proteins; (2) thimerosal, an ethylmercury-containing preservative

One subject that has been very controversial for many years is the role of vaccinations causing Autism spectrum disorder in children. Since Eric Gallup was a healthy baby until he received was his first measles-mumps-rubella (MMR) vaccination in 1986. His parent noticed his behavior and ability to communicate after took the vaccinated. Eric had a serious reaction to the vaccine, according to his parent. In the year of 1989, he was diagnosed with autism spectrum disorder. Eric Gallup’s parents developed a hypothesis that childhood vaccine was responsible for Eric's autism spectrum disorder.

This however is purely speculation. Even the head of the Autism Science Foundation had this to say, "We have to move forward and be willing to accept what science tells us: Vaccines do not cause autism." Many believe that this idea came from the fact that children receive vaccines around the same time they would start showing signs of autism. This means that though it would appear that the children got autism due to vaccines, but that is simply not true. Actually there were seven important studies included in major medical journals saying just that. So despite all of the deliberation over weather or not vaccines are safe, they are very safe.

There has been much research and debate on whether vaccines cause autism, however, there is no evidence that Measles, Mumps, Rubella vaccination is associated to autism. Parental age and pregnancy complications have been the most studied risk factors for ASD especially low birth weight and prematurity. Three of five studies have found low birth weight to have a significant association with autism spectrum disorder. Mothers aged 35 years and older and fathers aged 40 to 49 years have also found significant associations with autism. Pregnancy complications have been found to be significantly associated with ASD according to a 2012 systematic review. Prenatal, perinatal, and neonatal overall health have been explored by many studies. A cohort

Vaccinations have been by far one of the most important medical practices in history. At one time, some of the most lethal diseases in the world were common place. With the initiation of vaccines, these diseases have been mostly eradicated. Unfortunately, there are some parents who are now refusing to vaccinate their children due to worries of a possible link between vaccinations and autism. All children should be vaccinated because there has been no verified proof of a link between vaccinations and autism.

The argument that vaccines cause Autism began in 1998 when British surgeon Andrew Wakefield published a study, suggesting that the MMR vaccine given to prevent measles, mumps, and rubella increased autism in children. Autism is a mental condition involving issues in the brain development, it is

According to Shangraw (2012), there is no concrete etiology of autism because it is not diagnosed by its cause but on observed behaviors. The Autism-Society (n.d.) stated that a possibility for the cause of autism is the abnormalities in the brain structure or function. In an MRI research study by Piven et al. (1995), they found that an individual with autism spectrum disorder had a higher total brain volume and tissue compared to a person who is not on the autism spectrum disorder. Genetic problems and environmental factors can be a cause of autism spectrum disorder, according to the Mayo Clinic (2014). In genetic problems such as fragile X syndrome or Rett Syndrome, it can be associated with autism spectrum disorder. There is ongoing research regarding environmental factors and exploring ideas such as viral infections, pregnancy complications, and / or air pollutants to determine if they are active factors of autism spectrum disorder.
