Autism usually appears since the child was three years old. Symptoms generally marked difficulty communicating verbally and nonverbally, also difficult social interaction and activity. Children with autism tend to be arbitrary and difficult to be directed, they like to live in their own world without considering the others. Symptoms of autism can be mild, moderate, to severe, so that parents may not realize that children suffering from autism. Is autism hereditary? Let’s see more about this neurological disorder.

The cause of autism there are three things, namely genetics, chromosomes and the environment that affects children starting from the womb until after birth. Genetic factors can not be changed. Until now, researchers are still conducting experiments genetically modified but not yet produced results. While the causes are derived from the environment can be minimized.

Normal human body is designed to filter and remove excess heavy metals from the body. While the system in the body of people with autism, apparently unable to remove heavy metals and even customize with an excess of heavy metal. From the research found that the amount of heavy metals can be 100 times more than the normal threshold on the body of an autistic child. Even when the baby is born with autism, they’ve got heavy metal content derived from the mother. Metals can be increase because exposure of substances that exist in nature, such as food. Examples are fish that contain mercury, or metal aluminum from cooking appliances. Children’s toys are also unsafe because it contains metal, but not all.

Vaccination is said to be one action that is usually aggravating levels of autism. Apparently there are some vaccines that still contain heavy metals. Vaccination was later become a trigger symptoms of autism in children because of the level of heavy metals increased dramatically, exceeding the threshold that can be tolerated. In this case the boys are more susceptible due to vaccinations triggered autism than girls.

Is autism hereditary? Incidence of Autism has not derivate although genetic factors can not be changed. If people with autism have a child, that child will not necessarily suffer from autism also. Moreover, even people with autism have a better understanding of autism than lay people. Don’t miss for other article about how to make an omelette.
