The information on autism causes is just beginning to be developed. This is because the syndrome is very complex and there is often little or no evidence of a direct cause. Most research indicates some type of genetic component, but just what that may be is not fully understood. However, modern research techniques that allow doctors to study the human brain and human genetics give some options for study.
Most researchers believe that autism is caused by a genetic component in combination with outside factors. These are considered to be the environmental component. When there is a genetic issue and an external factor the combination may produce autism. In many families there is a pattern of autism or other brain based disorders. This helps to support this theory. However autism can also occur when there is no family history of the syndrome.
The chemicals in the brain that allow cells to communicate and function correctly are known as neurotransmitters. People with autism have lower than normal levels of these neurotransmitters. In addition some research shows that people with autism have a larger brain than people without the syndrome. These two factors may cause differences in information processing. Many people with autism are very intelligent and gifted in specific areas including math, sciences and technology.
Autism is not caused by any specific form of parenting. When the condition was first diagnosed may researchers believed the mother's interaction with the child was causing the social withdrawal. This is now completely dismissed by experts in the field.
Autism is not considered to be a cognitive problem. People with autism express things differently and interact differently than others with the world around them. Autism is not caused by trauma or abuse and is not linked to any other health condition. Children with autism are as healthy as their peers and are not prone to infections or other conditions that may affect the brain.
Many parents believe that vaccinations containing thimerosal are the cause of increasing rates of autism. Thimerosal is a mercury based compound that is used in making vaccines. This view is not considered accurate by the medical community.
Autism causes, as claimed by some, may include pollutants, toxins and environmental contaminants. This is particularly true if mothers are exposed to these types of factors during the pregnancy. Researchers stress that these could be common pollutants found in the air that is in the home, workplace and the world at large.
There is some research that indicates a variety of different things may contribute to autism. These include food allergies that include wheat and dairy In addition a poor diet for a baby may also put a child at risk. Children that are given specific supplements often seem to overcome autism. This tends to support that it may be a dietary issue.
The supplement that has shown some of the most impressive results is Krill oil. Children taking one capsule daily had overall improvements. These improvements were reported by parents on surveys carried out over short and long time periods. Brain chemical levels also were normalized when Krill oil was provided on a daily basis.
Autism may also be linked to an immune disorder. Krill oil contains high levels of antioxidants that help to boost the immune system. This, in combination with the high levels of Omega 3 fatty acids may be the key to managing this syndrome.
