- Brain tumors – benign (noncancerous) or malignant (cancerous) growths in the brain.
- Meningitis – inflammation of the membranes of the brain or spinal cord.
Self-care
Fluid on the brain, also called water on the brain and hydrocephalus, is caused by birth defects, tumors, head or spinal injuries or bleeding in the brain during the birthing process. It can also develop after a stroke or bout of meningitis , which is an infection of the membrane that covers the spinal cord and brain.
Nutrition
There are more than 100 possible causes of hydrocephalus, but the underlying reasons are:
- Too much CSF is produced.
- One of the ventricles in the brain is blocked or narrowed, stopping or restricting the flow of CSF, so that it cannot leave the brain.
- CSF cannot filter into the bloodstream.
How do you remove fluid from the brain?
Too much cerebrospinal fluid in the ventricles occurs for one of the following reasons:
- Obstruction. The most common problem is a partial blockage of the flow of cerebrospinal fluid, either from one ventricle to another or from the ventricles to other spaces around the ...
- Poor absorption. Less common is a problem with absorbing cerebrospinal fluid. ...
- Overproduction. ...
What causes fluid on brain?
What causes water on the brain in adults?
What is extra fluid in the brain?
Is fluid on the brain serious?
Contents. Hydrocephalus is a build-up of fluid in the brain. The excess fluid puts pressure on the brain, which can damage it. If left untreated, hydrocephalus can be fatal.
Can fluid on the brain go away by itself?
It does not go away on its own and needs special treatment. Hydrocephalus is due to the accumulation of cerebrospinal fluid (CSF) in the cavities deep within the brain. These cavities are called ventricles.
What does fluid on the brain indicate?
Hydrocephalus -- which roughly means “water on the brain” -- is the buildup of fluid in the cavities (ventricles) deep within the brain. This fluid doesn't flow or get absorbed the way it should. That can lead to backups and blockages that put pressure on your brain.
How do you get rid of excess fluid on the brain?
A shunt is the surgical insertion of a drainage system. A catheter (a thin tube with a valve) is placed in the brain to drain away excess fluid from the brain into another part of the body, such as the abdomen, the chest cavity, or a chamber of the heart.
What is the life expectancy of someone with hydrocephalus?
Survival in untreated hydrocephalus is poor. Approximately, 50% of the affected patients die before three years of age and approximately 80% die before reaching adulthood. Treatment markedly improves the outcome for hydrocephalus not associated with tumors, with 89% and 95% survival in two case studies.
Can you live a normal life with a shunt?
Many people with normal pressure hydrocephalus enjoy a normal life with the help of a shunt. Regular, ongoing checkups with the neurosurgeon will help ensure that your shunt is working correctly, your progress is on track, and you are free to keep living the way you want.
What causes fluid on brain in adults?
Possible causes of acquired hydrocephalus include: bleeding inside the brain – for example, if blood leaks over the surface of the brain (subarachnoid haemorrhage) blood clots in the brain (venous thrombosis) meningitis – an infection of the membranes surrounding the brain and spinal cord.
Can hydrocephalus be treated with medication?
There is little use for medication in hydrocephalus. In some acquired cases, as with tumors and infections, resolving the underlying condition will resolve the hydrocephalus, but most patients still require surgical intervention.
Can Covid cause fluid on the brain?
Researchers at the University of California San Francisco found abnormalities in the cerebrospinal fluid -- the clear, colorless liquid that's found in the brain and spinal cord -- of 10 of 13 people who were infected with COVID and had thinking problems.
How Serious Is shunt surgery?
A shunt blockage can be very serious as it can lead to an build-up of excess fluid in the brain, which can cause brain damage. This will cause the symptoms of hydrocephalus. Emergency surgery will be needed to replace the malfunctioning shunt.
How is hydrocephalus treated without surgery?
Traditionally, hydrocephalus is treated with a shunt, a device that allows excess CSF to be “shunted” (moved) to another area of the body. Shunting is achieved by placing a permanent tube into one of the brain's four ventricles (a network of cavities that are filled with CSF) or into the space of spinal fluid.
How long can you live with a brain shunt?
The shunt event-free survival is approximately 70% at 12 months and is nearly half that at 10 years, post-operatively. Shunts that are placed to channel CSF to other parts of the body may fail due to malfunction or infection. Infections occur in less than 10% of all surgeries.
Where does a shunt drain fluid?
This is a tube from the brain ventricles into the abdomen (tummy). Other types of shunts drain the fluid into the chest. You can’t see the shunt from outside the body. Some people have a shunt for a short period of time and then it’s removed. Others have them for much longer.
What is the ventricle in the brain?
The ventricles are spaces inside the brain filled with CSF. An endoscope is a long tube with a light and a camera at one end. This allows your doctor to see inside the brain and make the tiny hole inside the ventricles.
How does a shunt work?
A shunt is a thin tube that drains away the extra CSF from the ventricles of the brain, to other parts of the body , where it is absorbed . Shunts are usually plastic and small, about 0.3cm (3mm) across. They have valves so that fluid can flow down from the brain but not back the other way. Shunts are also called ventricular catheters.
Why does CSF cause headaches?
Some brain tumours block the normal circulation of the CSF. Because the fluid can’t drain away, it builds up inside the brain and increases the pressure inside the head (intracranial pressure). This increased pressure can cause symptoms, such as headaches and feeling sick.
What is a shunt surgery?
A specialist team of doctors does your surgery. They are called neurosurgeons. The most common type shunt is the ventriculoperitoneal shunt. This is a tube from the brain ventricles into the abdomen (tummy).
What is the term for fluid build up in the brain?
Fluid build up in the brain is also known as ‘water in the brain’ or ‘hydrocephalus’ . The fluid is present in the ventricles, excess fluid can put pressure on the ventricles which in turn may even result in death. Find out more about water in the brain in the following paragraphs.
What is the best treatment for excess fluid?
1. Shunt Placement: Shunt placement is one of the most common treatments for excess fluid. This is an artificial drainage system which consists of a long flexible tube whose one end is placed in one of the ventricles and the other is tunneled into that part of the body which can absorb the CSF well.
Why does my baby have a lot of water in the brain?
It may also happen if the mother develops some infection during pregnancy. Some diseases like meningitis, brain tumors, etc. contribute to the fluid build up which may be responsible for excess water in the brain.
What is the function of the brain?

What does it mean when your eyes are fixed downwards?
Eye fixed downwards which is also known as sun setting of the eyes can be observed. It may also affect the eyesight as you may get blurred or double vision. Memory loss, change in personality, confusions, etc. may also be related to the fluid build up in the brain.
Where is the hole in the brain?
This is used when there is an obstruction in the ventricles of the brain. The surgeon makes a hole in the lower part of the ventricle from where the fluid drains out and reaches the base of the brain where it can be absorbed easily.
What is the water on the brain called?
Although hydrocephalus often is described as "water on the brain," the "water" is actually CSF — a clear fluid surrounding the brain and spinal cord. CSF has three crucial functions: It acts as a "shock absorber" for the brain and spinal cord; It acts as a vehicle for delivering nutrients to the brain and removing waste; and.
What is the meaning of hydrocephalus?
Hydrocephalus is a condition in which excess cerebrospinal fluid (CSF) builds up within the ventricles (fluid-containing cavities) of the brain and may increase pressure within the head.
What is the cause of hydrocephalus ex-vacuo?
Hydrocephalus ex-vacuo occurs when a stroke or injury damages the brain and brain matter actually shrinks. The brain may shrink in older patients or those with Alzheimer's disease, and CSF volume increases to fill the extra space. In these instances, the ventricles are enlarged, but the pressure usually is normal.
What is the success rate of hydrocephalus?
The success rate varies from 25 to 74 percent for NPH cases in which its cause is unknown. In general, the earlier hydrocephalus is diagnosed, the better the chance for successful treatment. The longer the symptoms have been present, the less likely it is that treatment will be successful.
What causes pressure hydrocephalus?
Normal Pressure Hydrocephalus results from the gradual blockage of the CSF-draining pathways in the brain. The ventricles enlarge to handle the increased volume of CSF, thus compressing the brain from within and eventually damaging or destroying the brain tissue.
How old do you have to be to get hydrocephalus?
Hydrocephalus can occur at any age, but is most common in infants and adults age 60 and older. It affects adult males and females, as well as people of different races, about equally.
Where is the burr hole in the brain?
In this operation, a tiny burr hole is made in the skull and a neuroendoscope (a small camera which is attached to a medical instrument) enters the brain. The neurosurgeon then will make a small hole (several millimeters) in the floor of the third ventricle, creating a new pathway through which CSF can flow.
How to treat fluid in the brain?
The most common treatment is the surgical insertion of a shunt that allows the CSF to flow to a different area of the body and become absorbed by the circulatory system. In very rare cases, doctors can use a small tool ...
Why does fluid in the brain go up?
An example is a condition known as aqueductal stenosis, where the narrow channel connecting two of the brain's ventricles becomes blocked. Because the fluid cannot pass through the ducts, it become s backed up and levels of CSF around the brain increase.
What happens when you have too much cerebrospinal fluid?
While all of us have a natural amount of cerebrospinal fluid, or CSF, surrounding our brains and spinal cords, having excess fluid can cause the spaces around the ventricles in the brain to widen. When this happens, additional pressure is put on the tissues of the brain and can cause considerable damage. Doctors and scientists do not completely ...
Can a concussion cause hemmorhaging?
Traumatic head injuries, such as those caused by accidents, and concussions may cause not only subarachnoid hemmorhaging but hydrocephalus as well . These injuries usually damage the ventricles and make it impossible for the CSF to leave the area surrounding the brain.
What is the procedure to drain cerebrospinal fluid from the brain?
A shunt drains excess cerebrospinal fluid from the brain to another part of the body, such as the abdomen, where it can be more easily absorbed. The most common treatment for hydrocephalus is the surgical insertion of a drainage system, called a shunt.
Why does a shunt stop draining cerebrospinal fluid?
Shunt systems can stop draining cerebrospinal fluid or poorly regulate drainage because of mechanical malfunctions, blockage or infections. Complications of ventriculostomy include bleeding and infections. Any failure requires prompt attention, surgical revisions or other interventions.
How does a surgeon use a camera?
In the procedure, your surgeon uses a small video camera to have direct vision inside the brain. Your surgeon makes a hole in the bottom of one of the ventricles or between the ventricles to enable cerebrospinal fluid to flow out of the brain.
What is the best test for hydrocephalus?
Brain imaging. Imaging tests can help diagnose hydrocephalus and identify underlying causes of the symptoms. These tests may include: Ultrasound. Ultrasound imaging, which uses high-frequency sound waves to produce images, is often used for an initial assessment for infants because it's a relatively simple, low-risk procedure.
Where is the cerebrospinal fluid absorbed?
The tubing is then tunneled under the skin to another part of the body where the excess cerebrospinal fluid can be more easily absorbed — such as the abdomen or a chamber in the heart. People who have hydrocephalus usually need a shunt system for the rest of their lives, and regular monitoring is required.
What type of exam is a neurology exam?
Neurological exam. The type of neurological exam will depend on a person's age. The neurologist may ask questions and conduct relatively simple tests in the office to judge muscle condition, movement, well-being and how well the senses are functioning.
When is hydrocephalus diagnosed?
In some cases, hydrocephalus may be diagnosed at birth or prior to birth.
How does cerebral fluid help the brain?
Cerebrospinal fluid plays an important role in brain function by: Keeping the brain buoyant, allowing the relatively heavy brain to float within the skull. Cushioning the brain to prevent injury.
What is the fluid that fills the brain?
Your brain floats in a bath of cerebrospinal fluid. This fluid also fills large open structures, called ventricles, which lie deep inside your brain. The fluid-filled ventricles help keep the brain buoyant and cushioned.
What is the buildup of fluid in the cavities of the brain?
Hydrocephalus is the buildup of fluid in the cavities (ventricles) deep within the brain. The excess fluid increases the size of the ventricles and puts pressure on the brain. Cerebrospinal fluid normally flows through the ventricles and bathes the brain and spinal column. But the pressure of too much cerebrospinal fluid associated ...
Why does hydrocephalus occur at birth?
Hydrocephalus present at birth (congenital) or shortly after birth may occur because of any of the following: Abnormal development of the central nervous system that can obstruct the flow of cerebrospinal fluid. Bleeding within the ventricles, a possible complication of premature birth.
Why does cerebrospinal fluid flow back and forth?
Flowing back and forth between the brain cavity and spinal column to maintain a constant pressure within the brain — compensating for changes in blood pressure in the brain. Excess cerebrospinal fluid in the ventricles occurs for one of the following reasons: Obstruction.
What is the most common problem with cerebrospinal fluid?
The most common problem is a partial obstruction of the normal flow of cerebrospinal fluid, either from one ventricle to another or from the ventricles to other spaces around the brain. Poor absorption. Less common is a problem with the mechanisms that enable the blood vessels to absorb cerebrospinal fluid.
How do you know if you have hydrocephalus?
Among adults 60 years of age and older, the more common signs and symptoms of hydrocephalus are: Loss of bladder control or a frequent urge to urinate. Memory loss. Progressive loss of other thinking or reasoning skills. Difficulty walking, often described as a shuffling gait or the feeling of the feet being stuck.
What is the fluid that surrounds the brain?
Your brain and spinal cord are surrounded by a clear liquid called cerebrospinal fluid (CSF). It’s made and stored in cavities in your brain called ventricles. It circulates around your brain, moving from ventricle to ventricle. It cushions and protects the brain and spinal cord, supplies them with nutrients, and removes some ...
Why does hydrocephalus happen?
Hydrocephalus happens when the natural system for draining and absorbing extra CSF doesn’t work right. The ventricles enlarge to accommodate the extra fluid and then press on different parts of the brain, causing a number of different symptoms. Hydrocephalus has many different causes.
What parts of the brain are affected by NPH?
The parts of the brain most often affected in NPH are those that control the legs, the bladder, and the "cognitive" mental processes such as memory, reasoning, problem solving , and speaking.
What is the most accurate method of pinpointing and documenting a person's cognitive problems and strengths?
Neuropsychological testing to document your dementia symptoms . This is the most accurate method of pinpointing and documenting a person's cognitive problems and strengths. Lab tests to rule out conditions that might cause similar symptoms. Your doctor also may recommend a few other scans or procedures:
What age do you get hydrocephalus?
Normal pressure hydrocephalus (NPH) is a type of hydrocephalus that usually happens in older adults. The average age of a person with NPH is over age 60.
Where is the shunt implanted?
The treatment in these cases is a shunt operation. A shunt is a thin tube that is implanted in the brain by a neurosurgeon. It is inserted into the ventricles to drain excess CSF away from the brain. The tube is routed under the skin from the head to another part of the body, usually the peritoneum (the lower belly).
How to prevent NPH?
Normal Pressure Hydrocephalus Prevention. There is no known way to prevent NPH. A healthy lifestyle, including not smoking, maintaining a healthy weight, and regular exercise, may help avoid conditions such as high blood pressure, heart disease, diabetes, and stroke that might contribute to NPH.
