The link between maternal cytomegalovirus and autism is an area of increasing scientific interest. Cytomegalovirus (CMV) is a common viral exposure that, if contracted during pregnancy, can lead to complications in foetal development. When CMV is passed from mother to foetus, a condition known as congenital CMV, it can impact the brain, hearing, and cognitive function. Some studies now suggest a possible connection between maternal cytomegalovirus and autism, particularly when infection occurs early in pregnancy.
CMV in pregnancy can be asymptomatic, making it difficult to detect without targeted screening. However, even in the absence of symptoms, maternal cytomegalovirus and autism risk may still be present. The virus can cause inflammation and damage to the developing brain, increasing the chances of developmental delays and neurological disorders, including autism spectrum disorder (ASD).
How Maternal Cytomegalovirus and Autism May Affect Foetal Development
Here are ways maternal cytomegalovirus and autism could be connected:
Impact of CMV on brain development
CMV in pregnancy can affect neural tissue, potentially leading to abnormal brain structure. This viral impact may contribute to cognitive and behavioural patterns commonly associated with autism.
Viral exposure and immune activation
The body’s immune response to viral exposure, such as cytomegalovirus, can also influence neurodevelopment. This inflammation may interfere with how neurons form and connect during critical stages of foetal brain development.
Long-term developmental outcomes
Children exposed to CMV in the womb may show a range of neurodevelopmental differences. Some studies indicate a higher prevalence of autism among those affected by congenital CMV, further supporting the maternal cytomegalovirus and autism connection.
