Hydrocephalus is a condition marked by the buildup of cerebrospinal fluid (CSF) within the fluid-filled spaces of the brain, called ventricles. This extra fluid can increase pressure inside the skull and stress brain tissue; effects vary widely but can affect nearly every part of daily life. Some people notice headaches, vision changes, balance problems, or difficulty with memory and concentration. In infants, an unusually enlarged head may be the first sign. Here’s more information on this condition and how it is treated:
Why Hydrocephalus Happens
CSF cushions the brain and spinal cord, delivers nutrients, and removes waste. Under normal conditions, the body produces and absorbs this fluid in a steady balance. Hydrocephalus develops when that balance is disrupted, and the fluid accumulates faster than the body can clear it. Several factors can trigger this disruption. Congenital hydrocephalus is present at birth and may relate to genetic factors or problems during fetal development.
Acquired hydrocephalus appears later in life, often following a brain injury, infection such as meningitis, tumor, or bleeding within the brain. A specific form called normal pressure hydrocephalus tends to affect older adults and can be mistaken for other age-related conditions. Understanding the underlying cause helps guide the approach a care team may recommend. Diagnosis usually begins with a review of symptoms and medical history, followed by a physical and neurological examination.
How Neurologists Diagnose This Condition
To diagnose any neurological condition, a neurologist assesses balance, coordination, reflexes, vision, and cognitive function to identify patterns consistent with fluid buildup. Imaging plays a central role in confirming a patient’s health status. A CT scan or MRI can reveal enlarged ventricles and show whether fluid pathways are blocked. In some situations, a specialist may measure CSF pressure or remove a small amount of fluid through a lumbar puncture to observe how symptoms respond. For suspected normal pressure hydrocephalus, this fluid trial can offer additional information.
How To Manage This Condition
After diagnosing hydrocephalus, a care team reviews the findings and discusses which approach may fit a particular situation. Management depends on the cause, severity, and the individual’s overall health. Not every case calls for immediate intervention. When symptoms are mild or stable, a specialist may recommend regular monitoring through scheduled appointments and periodic imaging. This approach lets the team track changes over time and decide whether further steps are needed.
Placing a Shunt
A shunt is a thin, flexible tube system that redirects excess CSF away from the brain to another part of the body, where it can be absorbed. One end sits in a ventricle, and the other typically drains into the abdominal cavity. A valve regulates the flow so that fluid moves at a controlled rate, and follow-up visits help the team confirm that the system continues to function as intended.
Undergoing Endoscopic Third Ventriculostomy
Endoscopic third ventriculostomy creates a new pathway for CSF to flow. Using a small camera called an endoscope, a surgeon makes an opening in the floor of the third ventricle so fluid can bypass a blockage. By creating new drainage within or between ventricles, this surgical option reduces CSF buildup caused by obstruction, not absorption.
Learn How To Manage Hydrocephalus
Hydrocephalus affects each person differently, and the appropriate approach depends on many individual factors. Some people benefit from careful observation, while others may work with their care team to explore surgical options. The goal of any plan is to address the fluid buildup and support daily function over the long term. Ongoing follow-up is also a fundamental part of the process, since health needs can may change with time.
