Overview 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 with hydrocephalus can damage brain tissues and cause a large spectrum of impairments in brain function. Although hydrocephalus can occur at any age, it's more common among infants and older adults.

Anatomy of the Brain Hydrocephalus is a condition that occurs when there is too much cerebrospinal fluid in the ventricles (cavities) of the brain. Cerebrospinal fluid (CSF) is produced in the brain, and is needed by the body to protect the brain and spinal cord, and carry away waste from brain cells.

Hydrocephalus Hydrocephalus is a buildup of fluid inside the skull that leads to brain swelling. Hydrocephalus means water on the brain.

- Overview of Hydrocephalus. Hydrocephalus literally means water brain. It means that there is more spinal fluid than normal in the ventricles -- fluid containing chambers within the brain. Persons with hydrocephalus often complain of headaches and unsteadiness.

Congenital Hydrocephalus - Topic Overview Normally, fluid flows through and out of chambers of the brain called ventricles, and then around the brain and spinal cord. The fluid is then absorbed by the thin tissue around the brain and spinal cord. But with hydrocephalus, the fluid can't move where it needs to or is not absorbed as it should be.

hydrocephalus Causes and symptoms. Hydrocephalus that is congenital (present at birth) is thought to be caused by a complex interaction of genetic and environmental factors. Aqueductal stenosis, an obstruction of the cerebral aqueduct, is the most frequent cause of congenital hydrocephalus.

Diagnosis One of two surgical treatments may be used to treat hydrocephalus. The most common treatment for hydrocephalus is the surgical insertion of a drainage system, called a shunt. It consists of a long, flexible tube with a valve that keeps fluid from the brain flowing in the right direction and at the proper rate. One end of the tubing is usually placed in one of the brain's ventricles.

- Normal Pressure Hydrocephalus. The brain and spinal cord are surrounded by a clear fluid called cerebrospinal fluid (CSF). This fluid is produced and stored in cavities in the brain called ventricles. It circulates around the brain, moving from ventricle to ventricle.t's formal name is Naegleria fowleri. Although first identified in Australia, this amoeba is believed to have evolved in the U.S. There are several species of Naegleria but only the fowleri species causes human disease. There are several fowleri subtypes.

- My question is: How long can you keep/store that kind of bottled water and still use it for food/drinking purposes? Does it ever go bad or bacteria, etc. starts growing in it? Hope this isn't a stupid question. Thanks in advance to all who will answer

Learn how UpToDate can help you. Hydrocephalus is the correct term for pathologic dilatation of the brain's ventricular system from increased pressure, usually due to obstruction. Ventriculomegaly is the appropriate term when dilatation is due to other causes, such as brain dysgenesis or atrophy.

Hydrocephalus Congenital hydrocephalus is present at birth. Causes include genetic problems and problems with how the fetus develops. An unusually large head is the main sign of congenital hydrocephalus. Acquired hydrocephalus can occur at any age. Causes can include head injuries, strokes, infections, tumors and bleeding in the brain. Symptoms of acquired hydrocephalus can include:

- Hydrocephalus, also called Water on the Brain is a condition in which there is an abnormal build up of CSF (cerebrospinal fluid) in the cavities (ventricles) of the brain. The buildup is often caused by an obstruction which prevents proper fluid drainage.

Adult-onset Hydrocephalus When an injury or illness alters the circulation of CSF, one or more of the ventricles becomes enlarged as CSF accumulates. In an adult, the skull is rigid and cannot expand, so the pressure in the brain may increase profoundly. Hydrocephalus is a chronic condition. It can be controlled, but usually not cured. With appropriate early treatment, however, many people with hydrocephalus lead normal lives with few limitations.

What is Hydrocephalus? Cerebrospinal fluid: A watery fluid that is continuously produced and absorbed and that flows in the ventricles within the brain and around the surface of the brain and spinal cord.Abbreviated CSF.CSF is produced by the choroid plexus, a series of infolded blood vessels that project into the cerebral ventricles, and it is absorbed into the venous system. If production exceeds absorption, CSF pressure rises, and the result is hydrocephalus.SF is produced by the choroid plexus, a series of infolded blood vessels that project into the cerebral ventricles, and it is absorbed into the venous system. If production exceeds absorption, CSF pressure rises, and the result is hydrocephalus.

Hydrocephalus Hydrocephalus is the abnormal enlargement of the brain cavities (ventricles) caused by a build-up of cerebrospinal fluid (CSF). Hydrocephalus can be caused by problems with CSF secretion, CSF flow or CSF absorption.

Hydrocephalus Hydrocephalus is an abnormal accumulation of cerebrospinal fluid (CSF) in the ventricles of the brain and can be caused by an impaired flow of cerebrospinal fluid, reabsorption, or excessive production of CSF. Hydrocephalus may cause increased intracranial pressure inside the skull.

HYDROCEPHALUS CONGENITAL ABNORMALITIES OF THE CNS AND HYDROCEPHALUS. HYDROCEPHALUS. Hydrocephalus is dilatation of the cerebral ventricles. This dilatation has a variety of causes, the common denominator of which is obstruction of CSF flow. Approximately 600-700 ml of CSF is produced daily by the choroid plexuses.

Hydrocephalus Hydrocephalus may be either congenital (present at birth) or acquired. An obstruction within the brain is the most frequent cause of congenital hydrocephalus. A normal brain (left) and one showing the enlarged ventricles of hydrocephalus. The additional fluid in the ventricles causes increased pressure on the brain.

Hydrocephalus (Water on the Brain) Hydrocephalus is a condition that occurs when fluid builds up in the skull and causes the brain to swell. The name means “water on the brain.”. Brain damage can occur as a result of the fluid buildup.

Hydrocephalus Water on the brain. Hydrocephalus is due to a problem with the flow of the fluid that surrounds the brain. This fluid is called the cerebrospinal fluid, or CSF. It surrounds the brain and spinal cord, and helps cushion the brain. CSF normally moves through the brain and the spinal cord, and is soaked into the bloodstream.

- There are three main types of hydrocephalus: 1  congenital hydrocephalus – hydrocephalus that's present at birth. 2  acquired hydrocephalus – hydrocephalus that develops after birth. 3  normal pressure hydrocephalus – usually only develops in older people.

Normal Pressure Hydrocephalus (NPH) About Normal Pressure Hydrocephalus. Normal pressure hydrocephalus occurs when excess cerebrospinal fluid accumulates in the brain's ventricles, which are hollow fluid-filled chambers. NPH is called normal pressure because despite the excess fluid, cerebrospinal fluid pressure as measured during a spinal tap is often normal.

Adult-onset 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.
