What Causes an Autism Spectrum Diagnosis?
GRASP :: FAQAutism spectrum diagnoses are now known to be largely genetic in origin, and runs in families. Twin studies have uncovered many examples of identical (monozygotic) twins having autism spectrum diagnoses. One may have autism and the other AS, but when one identical twin is autistic, the other one is as well. If autistic conditions were not genetic, this would probably not happen.
Related QuestionsWhat causes autism spectrum conditions?
Frequently Asked Questions - AASCENDAutism is a brain condition, present from birth, which affects the way the brain processes information. In 1995, the National Institutes of Health (NIH) concluded that autism probably results from a genetic susceptibility that involves multiple genes. A variety of factors could be associated with some forms of autism, including infectious, metabolic, genetic, neurological, and environmental factors.
Related QuestionsWhy is an Autism Spectrum Diagnosis Special?
GRASP :: FAQIt’s special because it is one of the few, if not the only condition that imparts strengths as well as weaknesses. People with autism spectrum diagnoses have normal to very high IQs, and many have special skills. A few of us have remarkable and even extraordinary abilities. These people are called prodigious savants. Many of us have islands of ability and what are known as splinter skills.

UM ASAC Frequently Asked QuestionsScientists are not certain what causes autism, but it is likely that both genetics and environment play a role. Researchers have identified a number of genes associated with the disorder. Studies of people with autism have found irregularities in several regions of the brain. Other studies suggest that people with autism have abnormal levels of serotonin or other neurotransmitters in the brain.

Autism Resources - understanding autism FAQGenetic inheritance is involved in the development of autism spectrum disorders. Genetic factors likely interact with environmental variables to result in the expression of autism. Neurobiological research indicates that autism is likely the result of genetically determined abnormalities in brain development. This abnormal brain development may start before the child is born.Related Questions
Dr. Gertrude A. Barber National Institute - FAQs about Autis...It is suspected that there may be multiple causes for ASD due to a complex interaction of genetic and environmental factors. Family studies have shed the most light on the genetic contribution to autism. Studies of twins have shown that in identical twins there is about a 75% rate of both twins having autism, while in non-identical twins this occurs about 3% of the time. The inheritance pattern is complex and suggests that a number of genes are involved.Related Questions
FAQResearchers from all over the world are devoting considerable time and energy into finding the answer to this critical question.

Autism Society of America: Environmental Health: FAQBelow is a list of frequently asked questions concerning environmental health and autism, and related issues.
Related QuestionsWhat is the prevalence of autism spectrum conditions?
Frequently Asked Questions - AASCENDIn 2003, a detailed, federally supported study was published on the prevalence of autism spectrum conditions among children aged 3 to 10 years in metropolitan Atlanta. Using 1996 data, that study showed the prevalence for autism was 3.4 per 1000, with a male-female ratio of 4 to 1. The study did not show a major increase in autism compared to studies done in the 1980s and early 1990s.
Related QuestionsHow can an autism spectrum disorders registry help individuals with autism and their families?
FAQ - WVASDRSince autism has been thought to be a low incidence condition, funds have not been adequately appropriated to find its cause or treatment. Guesses at the prevalence and incidence of ASD's do not merit the attention of the Federal Government. They need to see data.

UM ASAC Frequently Asked QuestionsCertain behaviors exhibited to stimulate the senses, such as switching a light on and off repeatedly or humming loudly. Uneven skill development. Some skills are normal or superior for their age while others show significant delay.
Related QuestionsIs the RDI® Program effective for everyone on the autism spectrum?
Learn and Grow: Understanding RDI with Connections CenterWe find that all people on the autism spectrum can benefit from the RDI® Program. It appears to be helpful regardless of IQ, language, gender or diagnosis. The most important factor in determining the rate of improvement is the degree to which we have to overcome obstacles like the child's desire to control others, and the presence of co-occurring illnesses.
Related QuestionsWhy is there a need for a registry for autism spectrum disorders?
FAQ - WVASDRWe really do not know how many people in the United States have an autism spectrum disorder. We can say with some certainty, that there are more than the 5 in 10,000 (autism) and 15 in 10,000 (all autism spectrum disorders) that has been reported from the 1970's through 2002. Studies from California suggested a 273% increase from 1987 to 1998. This alarming number drew the attention of the media and of Congress as well.
Related QuestionsWill the name of the individual with an autism spectrum disorder appear in the registry?
FAQ - WVASDRNo . Names are not being collected. They are not needed to know how many people have this syndrome. We do need to ensure that we do not enter a person twice (if they receive a diagnosis by two or more diagnosticians). We are asking the person reporting to use a designated standard method of coding for the cases that will allow the names to remain confidential.

Frequently Asked Questions, Social Skill Builder FAQA2: The US National Institute of Health estimates that one American child in 150 is affected with an ASD, compared with one in 10,000 a decade ago. As many as 1.5 million Americans today are believed to have some form of autism. The overall incidence is consistent around the globe, but is four times more prevalent in boys than girls. It's now estimated that one boy in 94 is diagnosed with autism.
Related QuestionsHow are autism and Asperger Syndrome diagnosed, and who can make a diagnosis?
Frequently Asked Questions - AASCENDCurrently, no single medical test exists that will definitively diagnose autism spectrum conditions. Neither AS nor autism can be diagnosed by looking at a blood sample or performing a brain scan. Although these are physical, neurological conditions, researchers are still looking for genetic or other physical causes that may lead to a definitive test. Short of this, the diagnosis is made on the basis of observable characteristics of the individual.

What is causing the rapidly rising rates of autism spectrum disorders (ASD)?
Autism Society of America: Environmental Health Frequently A...Research indicates that other factors besides the genetic component are contributing to the rise in increasing occurrences of ASD, such as environmental toxins (e.g., heavy metals such as mercury), which are more prevalent in our current environment than in the past. Those with ASD (or those who are at risk) may be especially vulnerable, as their ability to metabolize and detoxify these exposures can be compromised.

Related QuestionsWhat is the cause of Autism Spectrum Disorders?
Autism SANo single cause of Autism Spectrum Disorders has been discovered. It is believed that the difficulties of Autism Spectrum Disorders are biological in origin and that there is abnormality in the brain which is probably caused by a combination of factors. These factors can include genetics, viral infections or complications during pregnancy. Other potential causes such as environmental toxins, diet and the effect of MMR (Measles-Mumps-Rubella) vaccinations are also being investigated.
Related QuestionsCan Autism Spectrum Disorders be inherited?
Autism SAAlthough most siblings of children with an Autism Spectrum Disorder develop normally, it has been estimated that between 2 - 7% of families with one child with an Autism Spectrum Disorder have two children with an Autism Spectrum Disorder or related difficulties (e.g. language disorder). It has been reported that the incidence of having two children may be as high as 9% but this figure relates to autism only.
Related QuestionsCan Autism Spectrum Disorders be cured?
Autism SAExtensive research continues in search of a cure for Autism Spectrum Disorders. With appropriate support people with an Autism Spectrum Disorder can develop many skills and abilities throughout their life. Intervention should be implemented as early as possible in order to maximise development.
