According to Shattock and Savery in their work “Autism as a Metabolic Disoder” they assert that autism continues to be a disorder that has no etiology; meaning there is no a comprehensive study that explains the origin and causes that can be linked to the disorder (as cited in Evans, et al., 2008). This claim is based on the findings that were established in 1998 at Sunderland university UK. Howver, in a recent findings, a number of factors have been

Autism is a disorder in brain progress that comes to be obvious in earliest youth.

Autism is one of the most common disorders among children in the United States. Autism affects 1 in 68 children (Center for Disease Control, 2014). By comparison, this is more children than are affected by diabetes, AIDS, cancer, cerebral palsy, cystic fibrosis, muscular dystrophy or Down syndrome – combined (Autism Speaks, 2012). Boys are four times more likely to have autism than girls. This disorder typically appears during the first three years of life.

In the United States, the Center for Disease Control and Prevention reports that between 1 in 80 and 1 in 240, for an average of 1 in 110 children have an autism spectrum disorder, “ASD” (Nirv, Shah 2011). According to the National Institute of Neurological Disorders and Stroke, up to six out of every 1,000 children may be diagnosed with some form of autism. In addition, boys are four times more likely than girls to have autism. This means that as many as 1.5 million Americans today are believed to have some form of autism. Unfortunately, the numbers appear to be increasing rapidly. Autism is a disability that frequently appears during the first three years of life. It is the result of a neurological disorder that affects the

Over the past twenty years, researchers on Autism have made notable findings in comprehending prevalence rates and creating accurate assessments to gather current diagnostic criterion. A significant increase in the prevalence rate of ASD has led researchers to make further inquiries about the precision of the tests used to assist in the diagnosis of autism.

According to the article, considerable variation in the parameters used for the analysis of growth, making it difficult to compare results from different studies. The method used most consistently showed poor growth in height and height deficit was possible to compare between studies.

Statistics show that autism affects between two and ten people per every 10,000 inhabitants, with higher occurrence in men than in women. Its cause often unknown, although some experts attribute the development of the disorder to a combination of genetics and certain environmental

Approximately twenty years ago this disorder was considered very rare with statistics of 1 in 1,000 children being diagnosed. Now statistics have changed and approximately 1 in 88 children are being diagnosed with this disorder. Autism is defined as a developmental disability which significantly affects

Parents of an autistic children might ask, “why did my child develop autism?” Well scientists, doctors and researchers have came to a conclusion that autism is not only a disorder but a spectrum. “Autism Spectrum Disorder according to Diagnostic and Statistical Manual of Mental Disorders (DSM -5) in 2013, autistic disorder were classified as distinct subtypes, includes Asperger’s syndrome, childhood disintegrative (CDD), and pervasive development disorder (PDD)” (“Autism Opposing Viewpoints”). Autism is a characterized by symptoms sach as inability to socialize, hyperactive, and are likely to have severe intellectual disabilities, which is categories as Autism Spectrum Disorder (ASD). Scientists and doctors have said that the cause of autism

According to Losinski, expert in special education, autism spectrum disorder afflicts 1.5% of the children in the United States (12). That means over 1 million children in the United states have been diagnosed with autism. TACA (Talk about Curing Autism) reported that, “more children will be diagnosed with autism this year than with AIDS, diabetes [and] cancer combined” (28). The Autism Response Team at Autism Speaks record that 1 out of 42 boys and 1 in 189 girls are diagnosed with autism in the United States. Yeargin-Allsopp conducted a study with his colleagues and their findings concluded that although boys are 4 times more likely to develop autism, girls are more likely to develop the more severe cases (36).

Stated previously autism is neurodevelopmental disorder that affects the brain by disrupting social and cognitive functions. For the best non-invasive way to see the affects on the brain is an MRI machine. Evidence shows that an increase in size of the overall brain is one of the primary signs; more specific the parieto-temporal lobe, and enlargement of the cerebellar hemisphere volumes was a common sign of Autism. Also abnormalities in the limbic system and cerebellum contribute the pathophysiology of autism. These changes are most related to the abnormal brain development in early life. To simplify things, autistic children have excessive amount of nerve fibers, but they do not work well and there for communicate between fiber is non-existent. Because of these large amounts of fiber explains the overall enlargement of the brain. Even though at birth the brain is normal or smaller than normal size, it goes through a period of rapid growth between six to fourteen

Autism spectrum disorder (ASD) is characterized by the early-onset inability to engage in social interaction, communication, and restricted, repetitive behavior. It is commonly known to be a developmental disorder. Genetics, in conjunction with developmentally early environmental factors, play a key role in the causation of autism. Studies show that autism is more prevalent in males than females, although there is not much difference in individuals with intellectual disability. Because atypical development is now being recognized early in toddlers, children are now frequently diagnosed at the age of 2 years and last into adulthood, although symptoms may improve over time. A wide range of health care providers are the first professionals to

This study involved forty-five boys with autism spectrum disorder, ages four to eleven years old, and forty-five boys with typical development, ages 2-6 years old. On the basis of selection, boys with ASD were recruited on a national and local standard. On the contrary, participants with typical development were recruited
