Neurogenesis Altered From Accidental Recombination: A Possible Cause For Excess Neurons In Autism

Neuron Number and Size in Prefrontal Cortex of Children with Autism (Courchesne, et al) refers to the standard of fixed, immutable neurogenesis - after initial early brain development. The group seems to have some focus upon insisting that the fix is in with regard to autism being present from earliest fetal development. For some in the autism spectrum this very likely holds true.

Courchesne and cohorts "...propose that increased neuron number in the PFC is a key contributor to brain overgrowth in autism. Neurogenesis is complete before birth in the PFC and in all of the cerebral cortex. Developmental programmed cell death (apoptosis) occurs before and shortly after birth, and these processes affect the net number of neurons in childhood."

The big therefore, is that vaccination cannot cause autism because the fix is in for some who have been labeled autistic; at least this is what has been proposed in many media outlets.

There are many experts who emphasize that "The human brain is not limited to the neurons it is born with, or even the neurons that fill in after the explosion of brain development in early childhood." (Neurogenisis: How To Change Your Brain, Perlmutter)

Research has shown that neural regeneration occurs after injury. Adult neurogenesis and neural regeneration are mechanized assonant to embryonic neurogensis. (Discoveries: Brain Cell Regeneration, Karger, Basel)

Adult neurogenesis, neuroinflammation and therapeutic potential of adult neural stem cells provides that, in some cases, neurogenesis might be modulated by drug treatments. In that, adult neurogenesis is proposed to transpire from use of antidepressants. (Phillipe Taupin) Would use of antidepressants, by the subjects utilized in Courchesne's research, cause the need for a second look at the outcome?

Neural stem cells continually replenish and can differentiate into neurons. It is all in our DNA. The question that some are asking is if human DNA residuals, present in vaccinations as a result of utilizing lung tissues of the aborted, is altering the process of neurogenesis - after birth; this via homologous recombination done without intention during the vaccination process.

I fear we may never be able to fully explore all the possibilities because of the love affair that media and the medical field has with assuring that vaccination, in no way, contributes to autism. This, even as vaccination has proven to contribute to onset of autism for many children. Autism is only a psychiatric label given when certain features are displayed; it is without known cause, and is usually accompanied by comorbid conditions with known medical cause. The comorbid conditions are many times easily identified as being caused by vaccination.

About our journey with autism... At the very beginning I figured, no big deal, we'll get our daughter normalized in no time and pretty soon she would be asking for the car keys. It didn't quite work out that way and as my entire family and I continued to work through the ebb and flow of her unique walk, we fell madly in love with her in all her glory. This articles are just an outreach in case the information is helpful to anyone.

For a real life look at one case of severe autism, just Google "Hello, Dr. Wells". It is a sixteen year account of autism that turned to schizophrenic like psychosis.

Some Possible Prenatal Causes of Autism

Autism is on the rise. Today the risk of having a child with autism stands at about 1:110. No one is sure if it is on the rise because of better diagnosis procedures or because of more children being diagnosed. Whatever the reason, it stands that you are more likely to have a child with autism, or know a child of autism than ever before.

While scientists haven't been able to pin down one precise cause of autism, there are several things which occur prenatally which may cause autism. It has also been found that there is a strong genetic element to autism. Studies have found that the chances for a child to have autism increases if there is a sibling or other close blood relative with autism.

None of the prenatal causes for autism have been proven 100% to be a cause of autism, but there is significant information to show that they are linked to autism.

One of those things is parental age. The age of the parents when the child is born has a direct impact on the risk of the child of having autism. It isn't sure yet if it is both parents, or just the mother or father. The reasons for this aren't clear. It could be because or increased complications as a parent gets older, as well as risks of mutations. Unlike other issues where maternal age matters more, in this case paternal age factors in more.

One potential prenatal causes of autism include some viral infections that the mother might have while pregnant. This is because the illness can cause the mother's immune system to go into overdrive. As her immune system goes crazy it can attack the foreign cells baby's body. Congenital rubella syndrome is the most common infection. Rubella, or German measles, is also linked to other things like schizophrenia, as well as blindness and deafness in babies.

There are other environmental things that could cause autism and birth defects. Those things are called teratogens. Some of them a woman has control of, others are beyond control. There are several studies exploring alcohol as one of the causes of autism, as well finding out if it's related to birth defects like fetal alcohol syndrome.

Women who are surrounded by specific chemicals that are found in pesticides have been found to have a higher incidence of autism in their families. In families where there is already a genetic element the chances that a child with end up with autism because of exposure to pesticides and fertilizers increase dramatically.

There are a lot of theories behind what causes autism. These theories are the ones that have the most agreement in the scientific community. There are some others that have been put out there, but not a lot of people are doing studies or believe that they are a significant cause. One of those is fetal exposure to ultrasound. There have been studies that have linked neuron disruption in mice with prolonged exposure to ultrasound. However, there hasn't been any significant human studies done on this subject.

There is no one agreed on cause of autism, but there are many things that can happen prior to birth that can push a child with a predisposition to it into having autism.
