What is the overall death rate associated with untreated hydrocephalus in newborns?

30-40%
50-60%
70-80%
90-100%

The correct answer is: 50-60%

The overall death rate associated with untreated hydrocephalus in newborns is indeed quite high, supporting the figure of 50-60%. Hydrocephalus, characterized by an accumulation of cerebrospinal fluid within the ventricles of the brain, can lead to increased intracranial pressure and subsequent neurological damage if not addressed. In newborns, the condition can result in severe developmental delays, cognitive impairments, and physical disabilities, often leading to a significantly high mortality rate in severe cases where treatment is not initiated. Because the complication rate is notably significant in this vulnerable population, the mortality figures range widely but tend to be in the 50-60% range for untreated cases. This emphasizes the critical importance of early detection and management of hydrocephalus in infants to improve survival and quality of life outcomes.
