Khaberni - A recent study found that some common medications used during pregnancy may be linked to an increased risk of children developing autism spectrum disorder.
Recent medical research seeks to explain the noticeable increase in autism diagnosis rates, which in the United States has reached one child out of every 31, compared to one out of every 150 children in the early first decade of the millennium, with multiple reasons likely including advances in diagnostic methods, environmental factors, and possibly the effects of some medications.
A study conducted by researchers at the University of Nebraska looked at several prescribed medications that affect cholesterol production in the body, including statins, some antidepressants, and beta-blockers, which are used to treat conditions such as high blood pressure, anxiety, and mood disorders, collectively referred to in the study as sterol synthesis inhibitors.
Despite cholesterol's importance in the body and its role in heart health, it also plays a fundamental function in the formation of brain cells and communication between neurons, which makes any dysfunction in its pathways of interest in studies related to brain development.
According to an analysis involving more than six million health records of mothers and children, researchers found that the use of these drugs during pregnancy was linked to an approximate 1.5 times increased likelihood of the child developing autism. Moreover, the risk gradually increased with the number of these drugs used, more than doubling for women who used four or more drugs from this category.
The researchers also indicated that pregnant women who took these medications should not stop them abruptly without medical consultation, due to the potential for serious health effects, such as withdrawal symptoms or worsening of the medical condition, emphasizing at the same time the importance of discussing therapeutic alternatives with the doctor when necessary.
The researchers stated that their findings do not mean that these medications are generally unsafe, but they open up questions about their effects during pregnancy, a sensitive stage in the development of the fetal brain.
The study relied on a vast database including millions of health records in the United States and evaluated the effects of several types of drugs, including antipsychotics, antidepressants, beta-blockers, and statins, which are widely used and prescribed to millions of patients annually.
The researchers also pointed out that the brain heavily relies on cholesterol in building its neural networks, and any disruption in its production may impact the development of the nervous system in the fetus, although the direct causal relationship is still undecided and requires further studies.
The study emphasized the necessity for doctors to balance the benefits of drug therapy and its potential risks during pregnancy, and to look for safer treatment options whenever possible.
These findings come in the context of other research addressing potential factors linked to autism, including studies that found no strong relationship between some common medications like pain relievers and autism, despite the general controversy on this subject.
