What is a common complication associated with hydrocephalus in infants?

Hydrocephalus in infants is characterized by an accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain, leading to increased intracranial pressure. One of the physical manifestations of this condition is the bulging of the anterior fontanelle. The anterior fontanelle, also known as the "soft spot," is an area on an infant's skull where the bones have not yet fully fused.

In hydrocephalus, the excess fluid causes the head to enlarge, and the tension of the fluid can lead to the fontanelle becoming tense and bulging outwards. This sign is a critical indicator for healthcare providers to recognize, as it helps in the assessment and diagnosis of hydrocephalus, guiding further investigation and management of the condition.

Other options related to hydrocephalus may include cognitive impairment due to potential brain damage from prolonged pressure, but the immediate and observable sign of bulging anterior fontanelle is a hallmark characteristic directly tied to the physical presentation of the disorder.
