A new study conducted at the University of Haifa found that among children with autism, which originates from genetic mutations, there is an accelerated development of neurons even in the embryonic stage, with the researchers estimating that this development could be the beginning of a chain that affects the development of autism. According to the study, published in the prestigious journal Translational Psychiatry From Nature, after the accelerated development, there was a rapid deterioration of the neurons, which was manifested, among other things, in low connectivity. The study found the recurrence of the phenomenon in children with autism originating from four different types of genetic mutations. "Neurons that develop at a normal rate develop appropriate defenses for the very complex activity they perform, among other things for the entry of ions and neurotransmitters, which may be toxic. According to the findings of our research, it is quite possible that the accelerated development of the neurons is also the one that causes the deterioration, which may affect the development of autism," said Dr. Shani Stern from the Sagol Department of Neurobiology at the University of Haifa, the author of the study.
About 85% of the cases of autism are called random (sporadic), when no genetic cause is found and there are no other cases of autism in the family. 15% of the other cases are caused by mutations in various genes. The research in cases caused by gene mutations is often based on mice as a model animal, when the research begins after their birth, and the neurons in the brain have already gone through several stages of development. Dr. Stern's research works through an innovative technological method of reprogramming mature cells of a specific person (for example, white blood cells), turning them into induced stem cells, which can then be sorted (turned) into another type of cells - in the case of the current study, neurons . That is, the neurons that were created carried the specific genetic load of the person from whom they were taken and could be tracked even before the "birth" stage.
In the current study, Dr. Stern and the research team, which included research students Yara Hussein and Utkaresh Tripathi from the Purple Department of Neurobiology at the University of Haifa, in collaboration with Prof. Ronan Spiegel and Dr. Tali Shkolnik from the Center for Rare Diseases at the Emek Hospital, asked to compare the development of cortical neurons (of the cerebral cortex ) of children with autism, which was caused by gene mutations, to the development of neurons of their brothers, who do not have autism - who actually constituted the control group. The children with autism who participated in the study had mutations in the following genes: , SHANK3, GRIN2B, UBTF and an abnormal number of segments on chromosome 7q11.23 and the choice of cortical neurons was due to the fact that some of the changes in the brain of children with autism are known to be related to changes in the cerebral cortex.
The results of the study revealed that among all children with autism, regardless of the genetic mutation, there was an accelerated development of the cortical neurons, already at the stage corresponding to the embryonic stage and in the first months of life. So already at this early stage, the neurons were considered "mature": they produced action potentials, they had large and strong currents, and they even began to produce active neuronal networks. Among the control group, which has normal development, the neurons did not produce action potentials, the electric currents were very small and they did not produce any neuronal networks at this stage of their development.
However, at the stage when the cortical neurons of the children without autism reached the stage where they began to produce action potentials and networks, the cortical neurons of the children with autism had already begun to deteriorate, as manifested, among other things, by low connectivity. That is, the cortical neurons of children with autism developed quickly and then deteriorated quickly.
According to Dr. Stern, it is possible that the early development of the neurons is what led to the deterioration. "Cortical neurons perform very complicated and complex operations, which can damage them, such as the entry of ions and neurotransmitters that may be toxic to them. Therefore, in normal development they develop defense mechanisms, in the early stages when they are not yet active. It is quite possible that the accelerated development caused them to start acting while they were still without the defense mechanisms, which of course could harm them. We are currently working in the laboratory on finding compounds and drugs that will slow down this rapid development in order to create protection for those neurons," said Dr. Stern.
She further added that the fact that children with four different types of mutations showed similar results in terms of development and accelerated deterioration indicates that it is possible that this is a phenomenon that characterizes autism in general, "the results of the study show that children who grow up to be those who are defined as having a developmental delay, actually begin with developmental acceleration. The fact that the results were common to different mutations in different genes and even in different chromosomes indicates that this may be a phenomenon that characterizes the brains of children with autism", she concluded.

It has been proven beyond doubt that there is no connection between autism and vaccines. And by the way, I have not vaccinated any of my six children. But it is important to put things on the table, no connection was found between vaccines and autism. They tested groups of children who never received a vaccine, and still the percentage of children with autism is the same as the group that received vaccines, and many more studies in the field deny this.
The article is interesting. Perhaps instead of the research field that will check how to stop the accelerated development, it is better to try and isolate the cause of it
If the research eventually leads to drugs that prevent or alleviate the symptoms.
This will be huge news.
We have been waiting for this for years.
Interesting research, the question of when they will find a way to prevent developmental delay among babies and children.
asked Dr. Stern
You are working on finding a way to slow down the rapid development of the neurons.
But whether/how, it is possible to identify the development in a fetus/newborn before the symptoms begin
to prevent this process from starting
Or before it starts?
I would be happy to answer you
Good luck with your research

Why? Has anyone asked you to thin the population by withholding life saving treatment?
Don't believe it!!! The only thing that causes autism is the injections of the children that are full of metals and mercury. It's all distractions.... notice some articles suddenly on the topic of autism. This is World War III. Run away from the children's vaccines and the corona vaccines like fire. Everything is poison!!!! Ministry of Health under the auspices of Agenda 2030 killers!!!@
Please don't engineer our heads. Everyone already knows that autism and other diseases come from the injections that are injected into us from the moment we are born!
