April 2nd marks the eleventh annual World Autism Awareness Day.

Autism is a form of pervasive developmental disorder. People get the disease due to insufficient attention from their parents or punishment from parents’ bad behavior.

Autistic people require others understanding their needs as they are more likely to be considered as aliens, rather than geniuses.

Currently, the rate of teens diagnosed with autism is estimated at 1 to 68 worldwide with an increasing ratio year by year.

Over 10 million people suffer from the disease in China with half of them teens aged below 14 years old.

If you see problematic behaviors of autistic people, please do not gaze at or discriminate them.

There is no known single cause for autism spectrum disorder, but it is generally accepted that it is caused by abnormalities in brain structure or function. Brain scans show differences in the shape and structure of the brain in children with autism compared to in neurotypical children. Researchers do not know the exact cause of autism but are investigating a number of theories, including the links among heredity, genetics and medical problems.

In many families, there appears to be a pattern of autism or related disabilities, further supporting the theory that the disorder has a genetic basis. While no one gene has been identified as causing autism, researchers are searching for irregular segments of genetic code that children with autism may have inherited. It also appears that some children are born with a susceptibility to autism, but researchers have not yet identified a single “trigger” that causes autism to develop.

Other researchers are investigating the possibility that under certain conditions, a cluster of unstable genes may interfere with brain development, resulting in autism. Still other researchers are investigating problems during pregnancy or delivery as well as environmental factors such as viral infections, metabolic imbalances and exposure to chemicals.
Genetic Vulnerability

Autism tends to occur more frequently than expected among individuals who have certain medical conditions, including fragile X syndrome, tuberous sclerosis, congenital rubella syndrome and untreated phenylketonuria (PKU). Some harmful substances ingested during pregnancy also have been associated with an increased risk of autism.

Autism is a worldwide problem.

10. Portugal (9.2 cases per 10,000 children studied)
Portugal has conducted its own recent research on autism, in a study involving 332,808 school-aged children. It found that the prevalence of the disorder was 9.2 per 10,000 children, with the disorder often being detected alongside other associated medical conditions, such as respiratory disorders. An additional study was done in the Portuguese Azores Islands, and the data there indicated a rate 15.6 autistic children per 10,000 children.

9. Hong Kong, SAR of China (17 cases per 10,000 children studied)
Hong Kong SAR of China also has had its own studies on autism prevalence among its population. The government of Hong Kong suggests that there are about 3,800 residents with the disorder in their jurisdiction. In Hong Kong, among its student population, less than one percent are affected with the disorder. One autistic charity organization in the city of Hong Kong helps autistic children by providing therapy, although similar organizations have found it difficult to exist there because of a lack of government support.

8. Brazil (27 cases per 10,000 children studied)
Brazil's Ministry of Health has published a guideline on the care of individuals with the disorder following studies showing the high rates of autism among young Brazilians. The disorder was recognized by federal law as a disability, and those with it are entitled to social benefits. However, there has been some deal of confusion and disagreement over the relationship between health, rights, and citizenship in Brazil. Statistics suggest that there are about 1.5 million people with autism who live in Brazil today.

7. Australia (45 cases per 10,000 children studied)
Australian studies on autism have found that the increases in autism cases in the country were not really as pronounced as researchers in many other developed countries have led people to believe. They felt there was just a case of the general populace and medical practitioners alike having more autism awareness, in addition to better diagnostic tools to identify the disorder in its milder forms. The Australian government has granted support for those families with children with formal autism diagnosis n the form of "Carer Allowances".

6. Canada (65 cases per 10,000 children studied)
Canada has conducted its own autism studies by way of the Public Health Agency of Canada. The Agency found that there was no correlation at all between autism and the MMR (mumps, measles, and rubella) vaccine. They found that after the introduction of the MMR vaccine, no increase of autism was detected. One study found the rate of autism to be one in 147 children in Canada.

5. USA (66 cases per 10,000 children studied)
The United States data on autism recently showed that one in 66 American children have the disorder, according to Center for Disease Control findings. However, at the start of the study, only one in 150 children had it. The American Academy of Pediatrics has suggested that guidelines for screening children should be followed more closely. The non-profit organization Autism Speaks stated that early detection and surveillance are two keys in detecting the disorder. Meanwhile, researchers found that both genetics and environmental factors are closely correlated to autism incidences.

4. Denmark (68 cases per 10,000 children studied)
Denmark made a study on autism as well, and had some problems with regards to determining what really caused the disorder. The results remain inconclusive.

3. Sweden (72 cases per 10,000 children studied)
Sweden made a study of the likely cause of autism, and its possible relation to vinyl flooring in homes. A study by U.S. and Swedish scientists showed that vinyl floors contain chemicals called phthalates, and these floors continually emit these chemicals into the inside the homes they are in. Still, some experts say that genetic factors also figure into the development of this disorder. It was also later found that prior misdiagnoses with other disorders was a leading cause for the rise of autism diagnosis in Swedish children.

2. United Kingdom (94 cases per 10,000 children studied)
The United Kingdom also conducted a study on autism among its children. This study involved school children between the ages of five and nine. It found 94 cases of autism spectrum conditions per 10,000 children. As a result, steps will be taken towards planning further diagnostic, social, and health services in Briatin, and to further the study of Autsim in more depth.

1. Japan (161 cases per 10,000 children studied)
Japanese research on autism cases in relation to the MMR vaccine (against mumps, measles, and rubella) have also been telling in regards to ruling out and identifying potential causes for the disorder. It found out that before the MMR vaccine era, autism in Japanese children was also already present. The statistics show that there are 161 cases per 10,000 children studied in Japan.

Autism is possibly cured currently.
