Maternal Infections and Autism: What Parents Should Know
Maternal infections such as flu, rubella, or COVID-19 do not directly cause autism. However, they may influence how genetic risk is expressed in the developing baby. When the immune system responds to infection, inflammatory molecules can affect foetal brain development, particularly in children already genetically susceptible.
Immune Activation
Cytokines and other immune signals can alter synapse formation and neural connectivity.
Timing and Type of Infection
Infections in the first or second trimester may have a stronger effect, especially when accompanied by fever.
Families seeking personalised guidance can explore consultations through Autism Detect. Some individuals also show overlapping ADHD traits, which can be explored through ADHD Certify.
