Genetics. Several different genes appear to be involved in autism spectrum disorder. For some children, autism spectrum disorder can be associated with a genetic disorder, such as Rett syndrome or fragile X syndrome. For other children, genetic changes (mutations) may increase the risk of autism spectrum disorder.

There is strong evidence to suggest that autism can be caused by a variety of physical factors, all of which affect brain development – it is not due to emotional deprivation or the way a person has been brought up. Evidence suggests that autism may be genetic. Scientists have been attempting to identify which genes might be implicated in autism for some years. Autism is likely to have multiple genes responsible rather than a single gene.

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.

This means that a child can be born with vulnerability toward developing autism which is later triggered by physical factors in their environment. 5. Theories of causes lead to interventions. Over the years there have been many theories about the causes of autism. In the 1950s and 60s, it was believed that autism was caused by cold parenting. This led to the promotion of ‘Holding Therapy’, an approach where the mother holds their child for a prolonged time and forces eye-contact in order ...

Autism involves atypical brain development which often becomes apparent in behavior and social development before a child is three years old. It can be characterized by impairments in social interaction and communication, as well as restricted interests and stereotyped behavior, and the characterization is independent of any underlying neurological defects.

Autism is more common in children born prematurely. Environmental factors may also play a role in gene function and development, but no specific environmental causes have yet been identified. The theory that parental practices are responsible for ASD has long been disproved. Multiple studies have shown that vaccination to prevent childhood infectious diseases does not increase the risk of autism in the population.

Several different genes appear to be involved in autism spectrum disorder. For some children, autism spectrum disorder can be associated with a genetic disorder, such as Rett syndrome or fragile X syndrome. For other children, genetic changes (mutations) may increase the risk of autism spectrum disorder. Still other genes may affect brain development or the way that brain cells communicate, or they may determine the severity of symptoms. Some genetic mutations seem to be inherited ...

Autism spectrum disorder (ASD) is a developmental disability that can cause significant social, communication and behavioral challenges. There is often nothing about how people with ASD look that sets them apart from other people, but people with ASD may communicate, interact, behave, and learn in ways that are different from most other people.

It's not clear what causes autism. Nobody knows what causes autism, or if it has a cause. It can affect people in the same family. So it may sometimes be passed on to a child by their parents. Autism is not caused by: bad parenting; vaccines, such as the MMR vaccine; diet; an infection you can spread to other people

Autism in older children. Signs of autism in older children include: not seeming to understand what others are thinking or feeling; finding it hard to say how they feel; liking a strict daily routine and getting very upset if it changes; having a very keen interest in certain subjects or activities; getting very upset if you ask them to do something ; finding it hard to make friends or ...

Research suggests that autism develops from a combination of genetic and nongenetic, or environmental, influences. These influences appear to increase the risk that a child will develop autism. However, it’s important to keep in mind that increased risk is not the same as cause .

Studies suggest that children with autism tend to have other problems with how their brain functions, with as many as 20-30% developing seizures or epilepsy. What Causes Autism? The exact cause or causes of autism are still unclear, and some theories have sparked controversy, such as the role of vaccinations (see our article on vaccination safety here) or the importance of dietary factors such as gluten (see our article on gluten here.) There is clear evidence for a possible genetic link.

This led to the promotion of ‘Holding Therapy’, an approach where the mother holds their child for a prolonged time and forces eye-contact in order to remediate a presumed attachment disorder.

These disruptions may be the result of defects in genes that control brain development and regulate how brain cells communicate with each other. Autism is more common in children born prematurely. Environmental factors may also play a role in gene function and development, but no specific environmental causes have yet been identified.

Autism spectrum disorder (ASD) is a developmental disability that can cause significant social, communication, and behavioral challenges. The term “spectrum” refers to the wide range of symptoms, skills, and levels of impairment that people with ASD can have. ASD affects people in different ways and can range from mild to severe.

There is often nothing about how people with ASD look that sets them apart from other people, but people with ASD may communicate, interact, behave, and learn in ways that are different from most other people.
