What is the cause of congenital hydrocephalus in the fetus?

Congenital hydrocephalus in the fetus may be caused by a variety of reasons such as genetic abnormalities, infection, brain development problems, etc. It is recommended to undergo early examination and evaluation under the guidance of an obstetrician.

Hydrocephalus is a phenomenon of increased fluid in the brain caused by cerebrospinal fluid circulation or absorption disorders, which affects the normal brain structure and function of the fetus. Congenital hydrocephalus can usually be detected through ultrasound during pregnancy and is related to genetics, infection, environment and maternal diseases. For example, gene mutations may cause dysplasia of the cerebrospinal fluid circulation pathway, and infection with toxoplasmosis or rubella virus during pregnancy may also damage the fetal central nervous system. Maternal diabetes, gestational hypertension, etc. may also increase related risks.

Specifically, genetic abnormalities such as X-linked hydrocephalus is a typical one and is closely related to genetics; if the fetus is attacked by the virus due to reproductive tract infection, it may damage the periventricular tissue and cause hydrocephalus; others are simply brain development abnormalities, such as partial brain structure closure or developmental defects, which directly hinder the normal circulation of cerebrospinal fluid.

If you are diagnosed with fetal hydrocephalus, pregnant mothers should not be too nervous. You need to consult an obstetrician or neonatologist in time. They may recommend further MRI examinations to more clearly determine the extent and cause of the hydrocephalus. Some mild hydrocephalus can even be self-limiting, but severe cases may cause brain damage and require active treatment after birth. Regular prenatal checkups and communication with your doctor are very important, and do not ignore potential symptoms and signs.
