The study suggests a link between prenatal exposure to mercury and autism: would a common pregnancy containing Thimérosal increase the risk of autism?
- A debate at the end of the 20th century wondered if RHO (d) – the Immune globulin, a common prenatal treatment containing Thimérosal (a preservative based on mercury) was linked to the increase in autistic spectrum disorders (TSA).
- Researchers from the Institute of Chronic Diseases examined 53 autistic children, all non -Jewish Caucasians born between 1987 and 2001, to explore a potential link between prenatal exposure to the development of Thimérosal and autism.
- The study revealed that autistic children were more than twice as likely to have RH-Negative mothers (28.3% against 14.36% in the control group), with a 2.35 rating ratio, suggesting a higher risk of autism in children with Rh-Negative Mothers who received pregnancy plugs containing Thimérosal.
- Mercury can cause neurological problems, behavioral changes and engine malfunction. Thimérosal can cross the placental and hemato-encephalic barriers, potentially affecting the development of the fetal brain.
For decades, the medical community has worked to understand the complex causes of autism spectrum disorders (TSA). Although genetics plays a key role, environmental factors – in particular prenatal exhibitions – have also been widely studied. One of these factors is Thimérosal, Including a widely administered injection for pregnant women RH-Negatives.
At the end of the 20th century, a debate emerged on the question of whether a common prenatal treatment could be linked to the increase in autism spectrum disorders. The treatment, known as the Immun-Immune Rho (D) globulin, has been widely used to prevent a serious disease called HR disease in newborns. However, until the early 2000s, many versions of this TIR contained the thimerosalA curator made of mercury. A study published in the Journal of maternal and neonatal medicine to explore If there is a link between this exposure to mercury and the development of autism.
Researchers from the Institute of Chronic Diseases conducted a study involving 53 autistic children, who were all non -Jewish Caucasians born between 1987 and 2001. These children were assessed in America genetic centers, where they underwent in -depth tests to exclude other potential causes of their autism.
To understand the role of the Thimérosal, the researchers focused on the mothers of these children. They found that each mother had received an RHO (d) -imnuh globulin shot down during pregnancy and these The blows contained thimérosal. To put this in perspective, imagine a group of autistic children and each of their mothers had been exposed to this compound containing mercury during pregnancy.
By way of comparison, the researchers also examined a group of 926 non-Jewish Caucasian women who had visited the same prenatal care centers between 1980 and 1989. They found that around 14% of these women were from the RH-Negative, which could benefit from the Immun globulin shooting (D).
Mercury and the brain: science behind the connection
The study revealed a striking difference: autistic children were more than twice as likely to have RH-Negative mothers compared to children without autism. More specifically, 28.3% of mothers of autistic children were negative, while only 14.36% of mothers in the control group were RH-Negative. This results in a dimension report of 2.35, which means that the risk was significantly higher for autistic children.
Every mother of Rh-Negative from an autistic child had received at least one Immune globulin injection containing thimérosal – during pregnancy. These results suggest a possible link between the status of material HR, prenatal exposure to the risk of Thimérosal and Autism.
Mercury is a well -documented neurotoxin. Research has shown that Mercury exposure can have an impact on fetal brain development in several ways:
- Neurotoxicity – Mercury can interfere with normal neuronal growth (brain development) and connectivity or problems with brain function.
- Behavioral changes – Studies have linked mercury to the features commonly observed in autism, including repetitive behavior and challenges with social interaction and communication.
- Motor and cognitive effects – Prenatal exposure to mercury has been associated with development delays, motor dysfunction (movement and coordination difficulties) and learning difficulties.
A key concern of the Thimérosal is its ability to cross both placental and hemato-encephalic barriers, which means that mercury could reach the development fetus and accumulate in cerebral tissues. Animal studies have shown that ethylmercure (the form found in thimerosal) is easily transferred from the mother to the fetus and can persist in the brain long after exposure.
This study is aligned with previous research suggesting a link between prenatal exposure to mercury and neurodevelopmental disorders. A 2003 study by Holmes et al. noted that mothers of autistic children had a significantly higher rate of HR negativity (46%) compared to control (nine percent). Animal studies have shown that Exposure to Thimérosal can cause neurological and behavioral changes Similar to those observed in autism. Molecular studies have shown that even low levels of Thimérosal can cause neural damage, disturb the key routes and modify the structure of the brain.
In addition, in 2004, the California Environmental Protection Agency Classified Thimérosal as a development toxin, recognizing its potential to cause neurological and behavioral effects in children.
Although the study suggests a possible link between exposure to Thimérosal and Autism, it has not established causality. Researchers highlight the need for more studies to confirm their results and explore other potential factors.
