Internal hydrocephalus brain - it is a disease that develops in humans due to accumulation of fluid in the ventricular system, and other parts of the brain.The main factor in the development of internal hydrocephalus becomes excessive generation of an spinal CSF outflow and bad in the future.
This can occur for a number of reasons: - injuries, if the body has penetrated infection in tumors in the brain.In the end, it all leads to the fact that the accumulation of fluid increases the size of a human skull, thins the walls of the ventricles of the brain, as a result of problems with the body of paralysis appear.
If there are certain symptoms that a person may feel the moderate internal hydrocephalus often no symptoms makes itself felt at the inside of the brain hydrocephalus.Despite this, the disease prevents proper circulation in the brain.Often the occurrence of this type of disease is associated with poisoning in the body.Do not neglect the disease and leave everything to chance.Necessarily need to
Hydrocephalus inner adult
Usually internal brain hydrocephalus occurs in young children, but there are numerous instances of this disease in adults.
In adults, it is divided into two types:
- internal replacement hydrocephalus.
With such hydrocephalus disrupted the process of removing cerebrospinal fluid from the skull.This name disease was a consequence of the increase of fluid in the ventricles of the brain.But this title is not quite justified, since the pressure of the liquid itself in the brain is increased periodically.Often the disease develops in concussions investigation, surgery, stroke.
Internal hydrocephalus substitution - is this a kind of disease, in which due to various reasons the volume of the brain is significantly reduced, and the remaining space fills the cerebrospinal fluid.Employees of the Research Institute of Novokuznetsk, checking blood flow in the brains of patients with this type of the disease, found the following: almost all subjects were the cause of the disease of dysfunction of the cervical vertebrae, atherosclerosis, addiction to alcohol and other negative factors.It is worth noting a decrease in the intensity of the examined blood flow.Scientists suggest that this is due to the slow work of the brain.Experts recommend the use of diuretics, and drugs that promote vasodilatation.
open internal and external hydrocephalus
open internal hydrocephalus - a form of the disease, in which the characteristic of the expansion of the ventricular brain systems and there is spreading of cerebrospinal fluid CSF system, without any obstacles, in contrast to the closed inner (occlusal), wherefluid outflow path has obstacles that have been educated for various reasons (tumor, trauma, etc.).
Hydrocephalus can be external and internal.In the case of an open outer form of the disease, the subarachnoid space is expanding and overflowing with hydrocephalus and is followed by thinning of the material brain.The clinical picture when it looks as follows: the size of a human head unnaturally large, there is a discrepancy sutures of the skull bones become thinner.Unnatural head size can be observed in utero, it may affect the subsequent course of childbirth.Neurological disorders affect human coordination, can be seen on the arms, legs, tremors, especially in young children.There are pretty clear signs of stagnation in the area of the fundus.
external hydrocephalus - a separate nosological species or complication of brain pathologies, which are often the tumor, stroke, infectious diseases and other.External hydrocephalus in humans manifests itself as follows: nausea, vomiting, severe headache, constantly sleepy.There are external congenital and acquired hydrocephalus.The first appearance of the disease arises as a consequence of which the fetal brain damage or malformations in mind.The second type - this is the reason of traumatic brain injury or inflammation.From other species it is distinguished primarily by the fact that he could not identify, for example, the elderly foreign hydrocephalus occurs against the backdrop of high blood pressure or atherosclerosis.
internal asymmetric hydrocephalus
plays an important role, how strong is the intracranial pressure.Against the background of the development of the disease is an increase in the entire ventricular cavity, usually for the sides, which increases the amount of cerebrospinal fluid.Depending on the type of disease, the increase in the entire ventricular cavity may be asymmetrical, with occlusion of the cerebral aqueduct holes.Asymmetric ventricular change associated with any - any injuries or cases of interventricular plugging holes.Grow ventricular enlargement causes the death of brain tissue, resulting in a flattening of the convolutions.This primarily concerns the white matter.
gray matter of the brain remains intact and is subject to change only in the most severe cases of hydrocephalus development.Atrophy of nerve tissue in the disease there is a compression of the capillaries of the brain due to high intracranial pressure.Changes in brain tissues in hydrocephalus, not only, also vary ependyma of the ventricles.This is especially true of the vascular plexus, which are subsequently exposed to atrophy and loss of epithelium.
