What causes autism?
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
It is commonly thought that autism spectrum disorders are genetic disorders and that genetic differences account for problems in early brain development and behavior. For about 10% of children, we can identify a known cause such as Fragile X and chromosome 15 duplications. Researchers have identified several genes that may predispose to autism in some but not all children. Much remains to be learned about genetic factors.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 BCPoor parenting does not cause autism, although its symptoms can be confused with abuse or neglect. Autism is a biological condition that can be triggered by a number of factors, most of which are not yet understood. One cause is rubella, which can affect the fetus if the mother is exposed during pregnancy.Related Questions
Autism Society of America Santa BarbaraAlthough there is no known cause for autism, it is considered by many to be a genetic disorder with environmental triggers. There are many research facilities, including the MIND Institute in California, that are trying to discover the cause of autism. There is much controversy surrounding suspect environmental triggers including thimerosol in vaccinations, pesticides, heavy metals, etc.Related Questions
What 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.

Autism Speaks' Frequently Asked QuestionsIt is already known that certain behavioural and educational interventions do benefit some children with autism and it is generally thought that the sooner they begin the better.; Autism Speaks believes however that if we do not understand the biological mechanisms involved in autism then all interventions, and particularly biomedical interventions such as drugs or diet, are essentially experimental.

Serotonin has been found to be contributory in either genesis or maintainance of Autism. However, detailed studies have to be carried out to confirm this possibility.Related Questions

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 QuestionsQuality Health | AutismAutism tends to run in families, suggesting a genetic link. Because people with autism can be vastly different, scientists suspect a number of genes are responsible. Ongoing research is targeted at pinpointing these genes. Some experts also believe that environmental factors may play a part in causing autism, although scientists have studied several factors, including vaccines, and have yet to identify such a cause.Related Questions

Autism Speaks, Be Informed, What is Autism, FAQsAutism, part of a group of disorders known as Autism Spectrum Disorders (ASD), is a complex neurobiological disorder that typically lasts throughout a person's lifetime. The disorder is characterized by varying degrees of impairment in communication skills and social abilities, and also by repetitive behaviors. Symptoms range from mild to severe. One milder form of the disorder is known as Asperger Syndrome.
