What causes fluid on the brain in adults?

Extra fluid on the brain is a condition known as hydrocephalus. When there is an excess of CSF in the brain spaces, or ventricles, this causes the ventricles to widen and can lead to excessive pressure on brain tissue. Acquired hydrocephalus can be caused by injury or disease.

What causes water on the brain in adults? In some cases, water on the brain is congenital, caused by defects in the structure of the brain which impair the circulation and drainage of cerebrospinal fluid. Other cases are acquired, caused by damage to the brain such as a stroke or traumatic brain injury. In both cases, the buildup of fluid can be clearly seen in…

What are the symptoms of water on the brain? Water on the brain can also cause symptoms like vomiting, nausea, vision problems, seizures, sleepiness, and developmental delays. When these symptoms present in a patient, a doctor can order a medical imaging study to look at the brain and learn more about what is causing the patient’s symptoms.

What is the treatment for water on the brain? It is not possible to cure water on the brain, but the condition can be treated. Treatment involves inserting a shunt into the brain to provide a drainage method. The shunt is a flexible plastic tube which drains to another portion of the body which can reabsorb and eventually express the cerebrospinal fluid.

What are the symptoms of pressure on the brain? Signs and Symptoms of Pressure on the Brain. The three cardinal features of raised intracranial pressure include headache, papilledema and vomiting. The pain is usually worse upon movement, at night and upon waking after sleep.



Commonly noted symptoms of hydrocephalus in adults include:

  • Chronic headache
  • Nausea
  • Difficulty in focusing the eyes
  • Difficulty walking or changes in gait
  • Weakness in legs
  • Drowsiness
  • Changes in personality and behavior, for example, irritability
  • Seizures


  • The causes include:
  • Build-up of CSF in the brain can be due to damage to brain or blockage of the pathway for flow of CSF. This could be due to
  • Injury to head or brain
  • Brain infection such as meningitis
  • Medical conditions affecting the brain such as hemorrhage, tumor, stroke
  • Surgeries to the brain


  • Get the vaccination done for meningitis
  • Wear helmets to prevent head injury when riding two wheelers
  • Wear the seat belt when driving a car


The complications include:

  • Dementia or forgetfulness
  • Falls due to difficulty in walking
  • Difficulty controlling bladder and bowel movements
  • Shunt malfunction or failure in case of shunt insertion, which requires additional surgeries

The name means “water on the brain.” Brain damage can occur as a result of the fluid buildup. This can lead to developmental, physical, and intellectual impairments.

What causes excess fluid on the brain? The cause of hydrocephalus is a buildup of fluid in the brain. A person’s brain floats in a liquid called cerebrospinal fluid, which flows into the spaces surrounding the brain before absorbing into the bloodstream. The production, flow and absorption of the cerebrospinal fluid must maintain a balance to keep normal pressure inside of the skull.

How do you drain fluid from the brain? Surgery for hydrocephalus often means implanting a shunt, a small tube that drains the excess fluid from the brain to another spot in the body for reabsorption. A device called a ventriculoperitoneal shunt drains the excess CSF from the brain to the abdominal cavity.

What caues fluid around the brain? Hydrocephalus or fluid around the brain occurs when excess cerebrospinal fluid puts extra pressure on the brain, causing it to swell. While the exact cause of fluid around the brain varies, it can be caused by a variety of medical conditions. An infant at the doctor’s office.
