Causes of Hydrocephalus or Water on the Brain
Causes of Hydrocephalus or Water on the Brain Hydrocephalus, also called water on the brain, is a condition where too much cerebrospinal fluid (CSF) builds up in the brain. It’s important to know the hydrocephalus causes for early treatment. This happens when there’s a block in the ventricular system or other issues causing cerebrospinal fluid accumulation. This leads to brain swelling reasons and can cause many symptoms as the skull gets more pressure.
We will look into the differences between being born with it and getting it later. We’ll talk about how things like tumors and cysts can cause it. We’ll also cover the specifics of communicating and normal pressure hydrocephalus. This will help us understand hydrocephalus and what might cause it.

ACIBADEM Health Point: The Future of Healthcare
We believe that everyone deserves access to quality healthcare, which is why we have established multiple branches in strategic locations. Whether you're in need of routine check-ups, specialized treatments, or emergency care, ACIBADEM Health Point is here for you.Introduction to Hydrocephalus
Hydrocephalus is a complex condition where too much cerebrospinal fluid (CSF) builds up in the brain. This can cause the skull to put too much pressure on the brain. It’s important to understand this by looking at how CSF works.
Cerebrospinal fluid (CSF) is a clear fluid that protects the brain and spinal cord. It’s made in the brain and moves through the ventricles before being absorbed. If CSF doesn’t move right, it can build up and make the ventricles bigger. This can push on the brain and mess with how it works.
Hydrocephalus can happen at any age, so it affects many people. It comes in different types, each with its own reasons and signs. Finding it early and treating it is key to helping people with it. Knowing about hydrocephalus helps us understand what those with it go through.

- Neurological Condition: Affects normal brain functions.
Here’s a table to help you understand hydrocephalus better:
| Element | Description |
|---|---|
| Hydrocephalus Explanation | An abnormal buildup of cerebrospinal fluid in the brain’s ventricles, leading to increased pressure. |
| Cerebrospinal Fluid (CSF) | A clear fluid that provides cushion and protection for the brain and spinal cord. |
| Ventricular Dilation | The expansion of brain ventricles due to the accumulation of excess CSF. |
| Neurological Condition | Affects brain function and can present symptoms of varied severity depending on the form of hydrocephalus. |
Congenital Causes of Hydrocephalus
Hydrocephalus, also called water on the brain, often starts before birth. It comes from genetic and developmental issues. These problems make it present at birth.
Genetic Factors
Many cases of hydrocephalus come from genes passed down in families. These genes affect how cerebrospinal fluid (CSF) moves and absorbs. This can cause fluid to build up in the brain. Causes of Hydrocephalus or Water on the Brain
Knowing about these genes helps with early diagnosis and treatment.
Developmental Disorders
Some disorders during fetal development can cause hydrocephalus. Neural tube defects are a big cause. They are serious problems with the brain and spinal cord.
Spina bifida is one such defect, where the spine doesn’t close right. It can lead to too much CSF. This disrupts the fluid flow and causes hydrocephalus.
Other issues with the brain’s development can also cause hydrocephalus at birth.
Acquired Causes of Hydrocephalus
Hydrocephalus, also called “water on the brain,” has many causes. It can happen after brain injuries or infections.
Traumatic Brain Injuries
Head trauma is a big reason for hydrocephalus. It can cause post-traumatic hydrocephalus. This happens when something hits the brain hard.
It can block or damage the paths for cerebrospinal fluid (CSF) to move. This fluid helps keep the brain healthy. Without it, fluid builds up in the brain.
Infections
Infections like meningitis can make hydrocephalus more likely. Meningitis inflames the brain and spinal cord coverings. It can hurt the brain tissues a lot.
This can cause swelling and scarring. These can block CSF flow or make it hard for the brain to absorb it. So, fluid builds up in the brain.
| Cause | Impact on CSF Flow | Resulting Condition |
|---|---|---|
| Traumatic Brain Injuries | Obstruction due to physical damage | Post-traumatic Hydrocephalus |
| Infections (e.g., Meningitis) | Swelling and scarring of brain tissues | Hydrocephalus |
Obstructive Hydrocephalus
Obstructive hydrocephalus is when a blockage stops cerebrospinal fluid (CSF) from moving properly in the brain. This can make intracranial pressure go up. It can cause big problems for people with this condition.
Tumors
Tumors in the brain can block the flow of CSF. They act like a wall, stopping the fluid from moving. This can make the brain swell and put pressure on other parts of the brain.
People with tumors might feel headaches, get sick, or have trouble seeing. Tumors like gliomas, medulloblastomas, and ependymomas often need surgery. Surgery can help remove the blockage and ease the pressure. Causes of Hydrocephalus or Water on the Brain
Cysts
Cysts are fluid-filled sacs that can block CSF pathways. They can cause non-communicating hydrocephalus. Arachnoid and colloid cysts are types that can make the blockage worse.
To fix this, surgery is usually needed. Surgery can remove or drain the cysts. This helps reduce pressure and lets the CSF flow right again.
Communicating Hydrocephalus
Communicating hydrocephalus is a special kind of the condition. It’s different because it’s caused by a CSF absorption issue. This means the cerebrospinal fluid (CSF) can’t be absorbed right in the subarachnoid space. This leads to more pressure in the brain.
This type of hydrocephalus happens when the CSF can’t move out of the brain’s ventricles. If the subarachnoid space is blocked, the fluid builds up. This can cause extracranial hydrocephalus.
Many things can cause communicating hydrocephalus. These include infections, brain bleeds, and spinal problems. Knowing what causes it helps doctors treat it better. Here’s a table that explains more:
| Cause | Description | Impact |
|---|---|---|
| Meningitis | Infection of the protective membranes covering the brain and spinal cord. | Can cause inflammation and blockage in the subarachnoid space. |
| Subarachnoid Hemorrhage | Bleeding into the subarachnoid space. | Disrupts normal CSF absorption, leading to CSF absorption issues. |
| Spinal Abnormalities | Structural defects in the spine that affect CSF flow. | Can block or alter the pathways for CSF absorption. |
Doctors look closely at how the CSF absorbs and the blockages in the subarachnoid space. This helps them treat communicating hydrocephalus better. Fixing these issues can really help with treatment. Causes of Hydrocephalus or Water on the Brain
Normal Pressure Hydrocephalus (NPH)
Normal Pressure Hydrocephalus (NPH) is a special type of hydrocephalus that mostly affects older people. It’s known for making the brain’s ventricles bigger without raising cerebrospinal fluid (CSF) pressure. People with NPH may have trouble walking, lose bladder control, and have memory problems. These are known as NPH symptoms.
NPH can happen for no clear reason or it can be caused by other health issues. When the cause is unknown, it’s called idiopathic hydrocephalus. Knowing how the cerebrospinal fluid (CSF) moves in NPH helps doctors figure out what’s going on and how to treat it.
Older people with NPH often have trouble thinking clearly. It’s important to tell these symptoms apart from Alzheimer’s disease or other types of dementia. Doctors use tests like imaging and spinal taps to make sure it’s really NPH.
| Characteristic | NPH | Other Dementias |
|---|---|---|
| Gait Disturbance | Common | Less Common |
| Urinary Incontinence | Frequent | Infrequent |
| Cognitive Decline | Variable | Progressive |
| CSF Pressure | Normal | Varies |
NPH can get worse over time, so catching it early is key. Doctors from different fields work together to help patients. If treated early, NPH symptoms can get better, making life better for those affected.
Hydrocephalus or Water on the Brain May Result From
Hydrocephalus, also called water on the brain, happens when too much cerebrospinal fluid (CSF) fills the brain’s ventricles. This makes the skull pressure go up. Finding out why hydrocephalus happens helps us understand how it can come from different causes. These causes often make the ventricles in the brain get bigger, which affects how the brain works and overall health.
Several key factors can cause hydrocephalus:
- Congenital Factors: Some babies are born with it because of genetic issues or problems during development that stop the CSF from flowing right.
- Acquired Factors: Adults can get it from head injuries or infections that mess with the CSF pathways.
- Obstructive Causes: Tumors or cysts can block the CSF flow, causing it to build up and increase skull pressure.
- Communicating Hydrocephalus: This type happens when the CSF can’t be absorbed or is made too fast.
- Normal Pressure Hydrocephalus (NPH): This mostly affects older people and has normal CSF pressure but still shows hydrocephalus symptoms.
These factors show the different reasons why hydrocephalus happens and how it can cause the ventricles to get bigger. Knowing the causes is key for diagnosing and treating it right. This way, patients get the right care for their condition.
Risk Factors For Hydrocephalus
Hydrocephalus is when too much cerebrospinal fluid (CSF) builds up in the brain. This can cause pressure and harm. Knowing who is at risk helps catch it early and manage it better. Causes of Hydrocephalus or Water on the Brain
Age
Age is key in knowing who might get hydrocephalus. Babies are at higher risk because it can start before birth. Studies link age to getting hydrocephalus.
Babies face a bigger chance of getting it than older kids and adults. Keeping an eye on them is very important.
As people get older, changes in the brain and CSF flow can raise the risk. In older adults, a type called Normal Pressure Hydrocephalus (NPH) is common. It can look like other brain problems.
Genetics
Genes play a big part in getting hydrocephalus. Some genes make it more likely. For example, genes that affect brain growth or CSF flow can cause it.
People with a family history of hydrocephalus might be more likely to get it. This shows why knowing your family’s health history is important. Genetic tests and advice can help.
Here’s a table with risk factors for different ages:
| Age Group | Risk Factors | Notes |
|---|---|---|
| Infants | Congenital defects, prenatal infections | High infant hydrocephalus risk due to developmental abnormalities |
| Children | Genetic mutations, brain tumors | Monitor hereditary predisposition |
| Adults | Injuries, infections | Conditions acquired post-birth |
| Elderly | Normal Pressure Hydrocephalus (NPH) | Often misdiagnosed as dementia or Parkinson’s disease |
Diagnosis and Monitoring of Hydrocephalus
Finding out if someone has hydrocephalus is very important. Doctors use special tools like MRI and CT scans to see if there’s too much fluid in the brain. These scans show the brain’s structure clearly, helping doctors make the right diagnosis.
Testing the cerebrospinal fluid is also key. This is done by taking a fluid sample from the spine. It helps find infections, bleeding, or other signs of hydrocephalus. This test gives doctors more clues about what’s causing the problem.
Managing hydrocephalus means keeping a close eye on the patient. Doctors check on them regularly and use scans to see how the condition is changing. This helps them adjust treatments like shunts or ETV. Keeping track of these changes helps make sure the treatment works well and improves life quality. Causes of Hydrocephalus or Water on the Brain
FAQ
What are the primary causes of hydrocephalus?
Hydrocephalus happens when too much cerebrospinal fluid (CSF) builds up in the brain. This can be due to blockages. These blockages can come from being born with them, infections, brain injuries, or tumors.
Can you explain what hydrocephalus is?
Hydrocephalus is a condition where there's too much cerebrospinal fluid (CSF) in the brain. This happens when the balance between making and absorbing CSF is off. It can cause the ventricles to get bigger and increase the pressure in the brain. It can happen to anyone.
What congenital factors lead to hydrocephalus?
Some people are born with a higher chance of getting hydrocephalus. This can be because of their genes or because of certain birth defects. For example, problems with the neural tube can cause inherited hydrocephalus.
How do acquired causes contribute to hydrocephalus?
Acquired causes of hydrocephalus include brain injuries and infections like meningitis. These can mess up how cerebrospinal fluid (CSF) moves or absorbs, leading to hydrocephalus.
What is obstructive hydrocephalus?
Obstructive hydrocephalus is when a blockage, like a tumor or cyst, stops the cerebrospinal fluid (CSF) from moving properly in the brain. This blockage makes the pressure inside the brain go up.
How does communicating hydrocephalus differ from obstructive hydrocephalus?
Communicating hydrocephalus is when the CSF can't be absorbed properly in the subarachnoid space. It's not because of a blockage in the ventricles. It can happen because of problems with absorbing CSF or blockages in the subarachnoid space.
What are the distinguishing features of Normal Pressure Hydrocephalus (NPH)?
Normal Pressure Hydrocephalus (NPH) is when the ventricles get bigger but the CSF pressure is normal. It usually happens in older people. Symptoms include problems thinking, walking funny, and not being able to control urination.
What are the multiple origins of hydrocephalus?
Hydrocephalus can come from many things like genes, birth defects, brain injuries, infections, tumors, and cysts. All these can cause problems with how the cerebrospinal fluid (CSF) moves and flows.
What are the risk factors for developing hydrocephalus?
Being young or having a family history of hydrocephalus increases the risk. Some people are more likely to get it because of their genes.
How is hydrocephalus diagnosed and monitored?
Doctors use MRI and CT scans to diagnose hydrocephalus. They might also look at the cerebrospinal fluid. Keeping track of how the disease changes and how well treatments work is done with regular check-ups and scans.
