A person with hydrocephalus can have a normal life expectancy with proper treatment, though the outlook varies widely depending on the cause of the condition, according to MedicineNet. With early medical intervention, children born with hydrocephalus often lead full lives with little or no disability.
Hydrocephalus affects all ages, but it is most common in the very young and the elderly, notes Healthline. Left untreated, it can cause brain damage and death, so early intervention is critical to improve prognosis.
Older adults with dementia tend to suffer more complications and have a poorer outlook, according to Mayo Clinic. When hydrocephalus is due to infection, stroke or brain injury, life expectancy depends on the severity of the underlying condition.
