HYDROCEPHALUS:

It is a condition more or less similar to water in the brain.

DEFINITION:

INCREASE IN CSF VOLUME DUE TO IMBALANCE BETWEEN PRODUCTION AND REABSORPTION OF CEREBROSPINAL FLUID.

CAUSE:

Impaired flow

Diminished reabsorption

TYPES:

It is divided into two types 

1.Non communicating [obstructive] hydrocephalus

2.communicating hydrocephalus 

1.COMMUNICATING HYDROCEPHALUS:

It is due to localized obstacle to CSF flow.

In this condition, a part of the ventricle is enlarged while the remainder does not.

2.NON-COMMUNICATING HYDROCEPHALUS:

It is because of reduced  CSF reabsorption.

The entire ventricular system is enlarged If hydrocephalus develops before the closure of cranial suture then *head enlarges*. 

If hydrocephalus after the closure of cranial suture then *no head enlargement but intracranial pressure is increased*.

TREATMENT OF HYDROCEPHALUS:

A most common treatment is the surgical insertion of f drainage system called a shunt.

THIS SHUNT SYSTEM MOVES FLUID AWAY FROM BRAIN TO DIFFERENT PARTS OF BODY VIA THE DIFFERENT SPECIFIC TYPE OF SHUNTS NAMELY

1.ventriculoperitoneal shunt

2.venticuloatrial shunt.
