Can Infections During Pregnancy Increase the Risk of Autism?
While autism spectrum disorder (ASD) is recognized as a neurodevelopmental condition characterized by a broad range of traits, its exact causes remain a subject of ongoing scientific investigation.
Researchers have made considerable progress in understanding autism, shifting away from viewing it as a disease toward recognizing it as a spectrum of traits with varying degrees of severity.
A significant area of focus in ASD research is the role of both genetic and environmental factors. Increasing evidence suggests that infections during pregnancy might be a contributing factor in increasing the risk of autism, or at least playing a role in triggering it.
Unraveling the Connection: Infections and Autism
One of the leading theories exploring the link between infections and autism centers around the body’s immune response.
Dr. Ian Lipkin, director of Columbia University’s extermination during pregnancy; however, mere exposure to a virus does not automatically lead to autism. Instead, it’s believed to be the inflammatory response triggered by the mother’s immune system that may play a role in disrupting normal fetal development.
This connection is supported by studies that have found elevated levels of cytokines, proteins that signal inflammation, in mothers of children later diagnosed with ASD.

The specific mechanisms by which maternal infections could increase the risk of autism are still being dal groan.
The developing brain is particularly vulnerable to disruptions during pregnancy. Researchers are investigating how
Dr. Irene Sanchez Martin, a postdoctoral researcher at the Cold Spring Harbor Laboratory, conducted a study using mouse models to explore the impact of maternal immune activation (MIA) – the body’s immune response triggered by an infection – and its potential role in neurodevelopmental disorders.

The study showed that exposing pregnant mice to viruses, which is equivalent to the first trimester in humans, led to immediate signs of developmental deficits in embryos within just 24 hours, Шевa

Martin emphasizes that findings in animal models cannot always directly translate to human health; however, mouse models offer a valuable tool for researchers to examine the direct impact of factors like MIA on fetal development, especially when comparing embryos from the same mother.
The results highlighted the possibility that disruption caused by inflammation in the amniotic fluid or placenta could be a key factor in increasing the risk of autism or similar neurodevelopmental disorders. The study
“We think that it’s the inflammation, not the specific infectious agent,” Dr
Lipkin says, “and there are many ways in which those can be triggered.”
While further research is needed to fully understand the link between infections during pregnancy and autism, the existing evidence suggests
that the mother’s immune reaction and the resulting inflammation may play a pivotal role.
How does the body’s immune response, specifically inflammation, potentially contribute to the development of autism in a fetus?
## Can Infections During Pregnancy Increase the Risk of Autism?
**Interviewer:** Welcome to the show, Dr. [Guest Name]. Today, we’re delving into a complex and often sensitive topic – the potential link between infections during pregnancy and the risk of autism spectrum disorder (ASD).
**Dr. [Guest Name]:** Thank you for having me. It’s important to approach this subject with nuance and accuracy. While we’ve made great strides in understanding autism, it’s crucial to avoid sensationalism and remember that correlation doesn’t equal causation.
**Interviewer:** Absolutely. So, what does the existing research tell us about the connection between infection during pregnancy and ASD?
**Dr. [Guest Name]:** There’s growing evidence suggesting a possible link. Studies have shown that maternal infections during pregnancy, particularly those causing a strong immune response, might increase the risk of ASD in children. [[1](https://pmc.ncbi.nlm.nih.gov/articles/PMC7784630/)]
**Interviewer:** Can you elaborate on how infections might influence fetal development and potentially contribute to ASD?
**Dr. [Guest Name]:** One leading theory focuses on the mother’s immune response to the infection. When the body fights off an infection, it releases proteins called cytokines, which signal inflammation.
This inflammatory response, while essential for fighting the infection, could potentially disrupt critical developmental processes in the fetus’s brain.
**Interviewer: ** So, it’s not just about contracting the infection itself, but rather the body’s reaction to it?
**Dr. [Guest Name]:** Exactly. Exposure to a virus doesn’t automatically lead to ASD. It’s the intensity and nature of the inflammatory response that seem to be key factors. Research is ongoing to fully understand the specific mechanisms involved.
**Interviewer:** What are some of the infections that have been linked to an increased risk of ASD?
**Dr. [Guest Name]:** Studies have investigated several infections, including influenza, rubella, and cytomegalovirus. However, it’s important to emphasize that most pregnant women exposed to these infections will not have children with ASD. [ [1](https://pmc.ncbi.nlm.nih.gov/articles/PMC7784630/) ]
**Interviewer:** This is certainly a complex area of research. What advice would you give to expectant mothers concerned about this potential risk?
**Dr. [Guest Name]:** Maintaining good overall health is crucial during pregnancy. This includes practicing good hygiene, getting vaccinated against recommended infections, and discussing any concerns with their healthcare provider.
**Interviewer:** Thank you, Dr. [Guest Name], for shedding light on this important topic.
