Question

Quizplus · Accepted Answer

The first trimester (first three months) of pregnancy is the most critical time for the development of the fetal brain. If a mother contracts rubella during this time, it can cause intellectual disability, as well as other birth defects. Rubella infection during the second and third trimesters is less likely to have a significant impact on the developing brain.
