hydrocephalus may occur if:

Cerebrospinal fluid acts as a cushion for the brain and spinal cord, supplies nutrients, and takes away waste products. Children with hydrocephalus may experience delays in reaching milestones like sitting, crawling, standing, walking, and talking. Hydrocephalus is associated with the abnormal buildup of cerebrospinal fluid within the brain's ventricles. Congenital means present at birth. Shunts also carry a high risk of infection.

Normally, CSF flows through areas in your brain called ventricles. It also helps by transporting waste products away from the central nervous system, helping it work at full capacity. In infants, hydrocephalus causes the fontanelle (soft spot) to bulge and the head to be larger than expected. Others may not experience improvement for weeks or months. The site navigation utilizes arrow, enter, escape, and space bar key commands. Non-communicating hydrocephalus happens when the flow of CSF is blocked along one or more of the narrow passages connecting the ventricles. In children, doctors check for: Your doctor may also use an ultrasound to get a closer look at the brain. Others may require long-term care. Urinary urgency is a strong, immediate physical need to urinate. CSF serves as a nutrient delivery and waste removal system for your brain. It is proposed that hydrocephalus may occur as a result of posterior fossa hypoplasia, where raised pressure occurs as a result of obstruction to flow of CSF from the head to the spine, and cerebral injury with raised pressure occurs in anencephaly by this mechanism.
