Question
What is the likelihood of a fetus developing hydrocephalus before birth? Will this affect the child’s intellectual development?
Answer
Hydrocephalus can be caused by an overproduction of cerebrospinal fluid, absorption disorders, or blockages in the cerebral aqueduct. Conditions such as intracranial hemorrhage and infections can also lead to hydrocephalus as a consequence. Moreover, hydrocephalus can occur at any stage of pregnancy, even if the mid-fetal brain development appears normal, it may still develop in the later stages. Therefore, ultrasound exams during pregnancy are crucial for early detection and assessment of hydrocephalus.
