Hydrocephalus

                         -------------

                      General Information



Hydrocephalus, or water on the brain, occurs when excessive

fluid accumulates within the skull or the fluid passages within

the brain.  This fluid accumulation produces increased pressure

on the brain.  Signs of hydrocephalus may include an enlarged

head, prominent forehead, lack of coordination, impaired

vision, mental dullness and convulsions.  Animals with mild

cases may not show all these signs and may only appear abnormal

in times of stress, excitement or head trauma.  Hydrocephalus is

usually present at or before birth (congenital) and may be

inherited (passed from one generation to another).  The disease

is most common in small breeds with dome- or apple-shaped heads,

such as Chihuahuas.  Mild cases of hydrocephalus can be treated

with medication and careful supervision to prevent stress and

head injury.  Some severe cases are treated surgically.  The

doctor will discuss the advisability and outlook for surgery

with you.
