The causes of autism

Other potential causes of autism are environmental toxins, including pesticides and heavy metals such as mercury. Autism is just one syndrome that now falls under the heading of autism spectrum disorders.

Very early indicators that require evaluation by an expert include: A diagnosis of ASD now includes several conditions that used to be diagnosed separately: A Handbook for Primary Care, Lippincott, Autism is more common in children born prematurely. Researchers at Johns Hopkins studied serum from mothers of children with autistic disorder, one of the most severe forms of autism, and mothers of non-autistic children and found antibodies that were different between the two groups.

Some research has shown that environmental toxins like mercury, a heavy metal that was used as a preservative in childhood vaccines, may be a contributing factor toward autism. Specialists who can do a more in-depth evaluation and make a diagnosis include: 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.

For example, young children with ASD might not understand what it means to wave goodbye. ASD symptoms can vary greatly from person to person depending on the severity of the disorder.

Some research has shown that environmental toxins like mercury, a heavy metal that was used as a preservative in childhood vaccines, may be a contributing factor toward autism.

This is sometimes called a Child Find evaluation. They may have unusual responses to people, attachments to objects, resistance to change in their routines, or aggressive or self-injurious behavior.

A belief that autism is caused by standard childhood immunization with mercury-containing vaccines persists despite many studies discrediting the link and retraction of the original paper linking autism to immunization.

Searching for the Cause of Autism

Researchers hope that understanding these alterations can help identify new opportunities for therapeutic interventions. Conditions that appear to be risk factors for autism include: The genetic landscapes of autism spectrum disorders.

What Causes Autism?

What exactly causes these suggested brain abnormalities isn't known, but one of the biggest theories is that it has to do with genetics.

Children with autism have trouble communicating. Even as infants, children with ASD may seem different, especially when compared to other children their own age.The causes of autism are still unknown and many theories have been disproven.

Find out why researchers think there's a genetic link between multiple. The idea that vaccines cause autism received yet another blow this week, with a new article in the British Journal of Medicine declaring the study by Andrew Wakefield, which originally found.

Autism Spectrum Disorder Fact Sheet

What Causes Autism? Experts are still uncertain about all the causes of autism.

Causes of autism

In all likelihood, there are multiple causes – rather than just one. Autism spectrum disorder (ASD) is a developmental disability that can cause significant social, communication and behavioral challenges.

Searching for the Cause of Autism

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. Researchers do not know the exact causes of autism but are investigating a number of theories, including the links among heredity, genetics and medical problems.
