Which age group is most at risk for developing hydrocephalus?

Infants and young children are most at risk for developing hydrocephalus primarily due to the rapid growth of their brains and the development of their cerebrospinal fluid (CSF) system. Hydrocephalus can occur when there is an imbalance in the production and absorption of CSF, leading to its accumulation in the ventricles of the brain.

In infants, congenital abnormalities or conditions such as spina bifida can lead to obstructive hydrocephalus, where the flow of CSF is blocked. Additionally, infections like meningitis can cause inflammation that affects the normal absorption of CSF. The infant's skull is still malleable, allowing for increased intracranial pressure to result in an enlarged head, which is a hallmark sign of hydrocephalus.

Furthermore, early signs of hydrocephalus in this age group can include irritability, vomiting, and developmental delays, making it crucial for prompt diagnosis and treatment to prevent complications. While hydrocephalus can occur at any age, the specific vulnerabilities present in infants and young children make them the most at risk group compared to adolescents, adults, or the elderly. In older populations, other conditions can lead to different forms of hydrocephalus, such as normal
