Hydrocephalus, popularly called cerebral edema - is a neurological disease caused by an excess of cerebrospinal fluid in the ventricular system of the brain. Typically, hydrocephalus is considered a disease of childhood, although the disease can be displayed, and in patients older than 18 years.


The most common signs of the disease are headache, nausea and vomiting , vision problems (inability to focus on a particular subject, is ghosting , blurred boundaries), changing the position of the eyeballs ( as if they are displaced downward , the pupil is also a bit " sinks ", creating the effect of " rolling eye ") , problems with the vestibular system ( loss of coordination in space , unsteadiness of gait , and uncertainty ) , clumsiness , lack of strength , memory loss , confusion in the mind , incontinence , excessive nervousness , irritability , and sometimes - drowsiness .

The dominance of certain features depends on the cause of the disease. For example , people in old age there is normal pressure hydrocephalus caused by age-related changes in the body. This condition is expressed primarily in the coordination of movements , occurrence of forgetfulness , slowness in thinking operations , less responsive to stimuli. One of the clearest signs of hydrocephalus in adults - deviances . They can take the form of emotional stupor , seizures , lethargy, depression, hallucinations , mania, delirium .

Cysts of the brain

The formation of a cyst is called a hollow, usually filled with fluid. They are formed in all organs of the human body, including the brain.


This condition can occur completely asymptomatic . There are common symptoms of a brain cyst – like feeling of pulsation and pressure in the head, ringing in the ears, flashing spots before the eyes, seizures, loss of sensation in parts of the body, passing partial paralysis, headaches, hallucinations and loss of consciousness. Local symptoms of cysts of the brain depends on the site in which it is located. For example, an imbalance characteristic of cysts of the cerebellum.

Classification and causes of apperance

There are cysts of the brain of two types, having different location:

  • arachnoid cysts are formed between the membranes of the brain as a consequence of inflammation, injury or intrathecal hematoma;
  • Intracerebral cavity - the result of replacing the lost brain tissue, in this case, too, the causes can be trauma, inflammation, as well as operations and hemorrhage.

Methods of treatment:

Implantation of a shunt system

endoscopic ventriculocisternostomy
