What are the Side Effects of Fluid on the Brain?

Fluid on the brain, also known as hydrocephalus, is a condition in which there is an abnormal accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain. This can cause increased pressure on the brain and can lead to a variety of symptoms and side effects.

Physical Symptoms

The most common physical symptom associated with hydrocephalus is an enlarged head due to increased pressure on the skull. Other physical symptoms may include headaches, nausea, vomiting, vision problems, balance issues, and difficulty walking. In severe cases, hydrocephalus can cause seizures or coma.

Cognitive Symptoms

Cognitive symptoms associated with hydrocephalus can vary depending on the severity of the condition. These may include memory loss, difficulty concentrating, confusion, impaired judgment, and difficulty understanding language. In more severe cases, hydrocephalus can cause intellectual disability or dementia.


Hydrocephalus is typically treated with surgery to relieve pressure on the brain by draining excess CSF from the ventricles. Medications may also be prescribed to reduce inflammation and swelling in the brain. In some cases, a shunt may be inserted to help drain CSF away from the brain and into another area of the body.
