Autism Cases
Autism is a disorder of neural development characterized by impaired social interaction and verbal and non-verbal communication, and by restricted, repetitive or stereotyped behaviour. Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organize; how this occurs is not well understood.[3]
Autism is usually caused by genetic transfer, and in rare cases, autism is strongly associated with agents that cause birth defects.[6] Controversies surround other proposed environmental causes, such as heavy metals, pesticides or childhood vaccines. The prevalence of autism is about 1–2 per 1,000 people worldwide, and the Centres for Disease Control and Prevention (CDC) report 20 per 1,000 children in the United States are diagnosed with autism as of 2012 (up from 11 per 1,000 in 2008).
Parents usually notice signs in the first two years of their child's life.[12] The signs usually develop gradually, but some autistic children first develop more normally and then regress.[13] Early behavioural, cognitive, or speech interventions can help autistic children gain self-care, social, and communication skills.[12] Although there is no known cure,[12] there have been reported cases of children who recovered.[14] Not many children with autism live independently after reaching adulthood, though some become successful. Characteristics
Autism is a highly variable neurodevelopmental disorder[17] that first appears during infancy or childhood, and generally follows a steady course without respite.[18] Symptoms gradually begin after the age of six months, become established by age two or three years,[19] and tend to continue through adulthood, although often in more muted form.[20] It is distinguished not by a single symptom, but by a characteristic triad of symptoms: impairments in social interaction; impairments in communication; and restricted interests and repetitive behaviour.

    Autism is a developmental disability caused by neurological dysfunction. It affects the way a person understands and responds to the world, how they hear, see, feel, sense, perceive and interpret everything around them. This may affect how they eat, sleep, dress, work, spend leisure time etc. They are likely to have repetitive behaviour patterns and restricted repetitive interests. Individuals with an autistic spectrum condition can have difficulties with language and communicating with others and with social interactions and relationships because there is an impairment of 2 way verbal and non verbal communication and impairment of flexible thinking and social imagination. People with autism can often have accompanying learning difficulties but everyone with the condition shares a difficulty in making sense of the world. Inflexibility and restrictiveness in activities and interests can lead to a person on the autistic spectrum having difficulty relating to others and making friends, an inability to engage in imaginary play, it can lead to ritualistic behaviours , obsessions and fears.…

    Autism manifests itself before the age of three, which causes the diagnosis age to be after three years old in most cases. The rise in diagnosed individuals has increased yearly since the 1950’s. In 2006 alone there was 2-6 people diagnosed out of every 1000. This is not easy to diagnose because Autism is not the same for every child. It fits into the category of spectrum disorders, which means there are a wide variety of behaviors and symptoms for it. With all exceptionalities or disorders early recognition is imperative. The earlier the child can be worked with on an issue like this the better results they will…

    Autism is a disorder of the brain that is characterized by impaired communication and social skills. Toddlers began to show signs of Autism by the time they are three years of age. Autism is one of the five pervasive development disorders. The range of Autism can be from people with severe impairments to individuals with high functioning skills who may be active but have a difficult time in social settings. Autism has been linked to genetics and environmental factors. Autism is better explained by rare mutations with major effects. A fraction of autism cases are traceable to genetic causes but are not inherited. Autism mechanisms are divided into two areas because the occurrence of it is not well understood. These areas are path-physiology and neuropsychological. These areas study the brain patterns of toddlers with Autism. There is no cure for Autism, but there are several therapies dedicated to treating the disorder. Since these treatments can be costly, many children go without treatment, leaving their parents to pick up the pieces as they continue to go through life.…

    There are genetic, environmental, immunological and neurological factors that are thought to play a role in the development of this disorder. Past studies of ASD have been inconsistent and controversial. According to the Journal of Leukocyte Biology in the article The immune response in autism: a new frontier for autism research by Paul Ashwood, Sharifia Wills and Judy Van de Water states that the studies have been inconsistent because of the small sample sizes, inappropriate controls, and the lack of consideration for ASD phenotypic heterogeneity. In recent years the studies have fixed these concerns and a link has been made with immunological factor. This immunological connection to ASD is now becoming widely accepted.…

    Autism Fact Sheet

    As I began reading the articles on autism I knew that I did not know much about this disorder and who were the most affected by it. It affects 1 out of 88 children in the world and most of them are males who are four times more likely to develop ASD than females (“Autism Fact Sheet”). Early signs of Autism may appear in the first months of life, and children with autism do not reach maturation as fast as normal children. One of the most common signs is that a normal child will point to objects or smile when seeing their mother before the end of their first year. But children with autism develop this behavior much later, symptoms like this may go on unnoticed by parents or doctors in infancy but, by the age of two to three it is clear that something is wrong with the child (“Autism Fact Sheet”). As I continued reading the article I started to realize how difficult this disease is for children and adults. Children have to rely on their parents most of their lives, and their disease can become more serious if not treated correctly. Autism can impair the lives of children, but it cannot impair their intelligence.…

    Autism is defined as a learning disorder of the brain that often affects learning and the way a person thinks. Most cases of autism are detected in children at a young age, most commonly around the two to three year mark. Children with autism often have problems developing cognitively, thinking in a traditional way, and in some cases, stomach problems. Statistically, autism is more prevalent in boys than in girls. Where one in forty two American boys are diagnosed with the condition, only one in one hundred eighty nine American girls are diagnosed. There is no one cause of autism in children, but a number of factors that can increase the risk of babies being born with autism. The cause of the disorder can be from rare gene changes that can…
