Bacteria is associated with autism in children

AUTISMA small study found a link between bacteria in the digestive system with the risk of autism in children. So it was found that there is a link between intestinal bacteria and autistic behavior in children.

Autism is a disorder of neural development characterized by impaired social interaction and verbal and non-verbal communication, and by restricted, repetitive or stereotyped behavior.

What is Autism?

Autism is known as a complex developmental disability. It is a disorder of neural development characterized by impaired social interaction and verbal and non-verbal communication, and by restricted, repetitive or stereotyped behavior.

Experts believe that Autism presents itself during the first three years of a person’s life.  The diagnostic criteria require that symptoms become apparent before a child is three years old. Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organize; how this occurs is not well understood.

People with autism have issues with non-verbal communication, a wide range of social interactions, and activities that include an element of play and/or banter.

Autism Characteristics

Overt symptoms of autism gradually begin after the age of six months, become established by age two or three years, and tend to continue through adulthood, although often in more muted form.

Autism (or ASD) is a wide-spectrum disorder. ASD stands for Autism Spectrum Disorder and can sometimes be referred to as Autistic Spectrum Disorder. In this text Autism and ASD mean the same. ASDs are any developmental disabilities that have been caused by a brain abnormality.

A person with an ASD typically has difficulty with social and communication skills. This means that no two people with autism will have exactly the same symptoms. As well as experiencing varying combinations of symptoms, some people will have mild symptoms while others will have severe ones. Below is a list of the most commonly found characteristics identified among people with an ASD.

Autism is distinguished not by a single symptom, but by a characteristic triad of symptoms: impairments in social interaction; impairments in communication; and restricted interests and repetitive behavior. Other aspects, such as atypical eating, are also common but are not essential for diagnosis. Autism’s individual symptoms occur in the general population and appear not to associate highly, without a sharp line separating pathologically severe from common traits.

A recent study even mentions that a blood test could reveal the risks of autism.

What causes Autism?

Autism has no single, known cause. Given the complexity of the disease, and the fact that symptoms and severity vary, there are probably many causes. Both genetics and environment may play a role.

  • Genetic problems. Several genes appear to be involved in autism. Some may make a child more susceptible to the disorder. Others affect brain development or the way that brain cells communicate. Still others may determine the severity of symptoms. Each problem in genes may account for a small number of cases, but taken together, the influence of genes is likely substantial. Some genetic problems seem to be inherited, while others happen spontaneously.
  • Environmental factors. Researchers are currently exploring whether such factors as viral infections, complications during pregnancy and air pollutants play a role in triggering autism.

No link between vaccines and autism
One of the greatest controversies in autism is centered on whether a link exists between autism and certain childhood vaccines, particularly the measles-mumps-rubella (MMR) vaccine. Despite extensive research, no reliable study has shown a link between autism and the MMR vaccine.

Avoiding childhood vaccinations can place your child in danger of catching and spreading serious diseases, including whooping cough (pertussis), measles or mumps.

Previous research also mention that pregnant women who eats salmon lowers the risk of autism in their babies. Pregnant women should also get enough intake of folic acid, this is because it was known that folic acid avoids babies from autism.

Intestinal bacteria and autism

According to a study mentioned earlier, shortage of some types of bacteria in the intestine increases the risk of children developing autism. The results were obtained after researchers analyzed bacteria in the intestine in 20 children with autism and 20 children without autism. It is known that children with autism have less intestinal bacteria. It is possible to cause them to become more vulnerable if exposed to harmful bacteria.

This study also showed that children with autism lack the three types of bacteria in the intestine when compared with children who do not have autism. The results are published in the PLoS One journal on July 3, 2013, as reported by Reuters (03/07).

“One of the reasons researchers are beginning to consider the link between intestinal bacteria with autism is the fact that many children with autism have digestive problems until they are adults. Research also shows that if we can overcome this problem, the behavior of autistic children will develop better,” said lead researcher Rosa Krajmalnik-Brown, researchers from Arizona State University’s Biodesign Institute.

This research can be further developed to learn a new way of digestive problems in children with autism. Moreover, these results can also be used to prevent and treat children with autism.

Previous research revealed that intestinal bacteria have significant roles, including in terms of digestion, maintain a healthy weight, and regulate the immune system. Although it found a link between autism and intestinal bacteria, but this study did not prove any causal link.
