    Internal hydrocephalus of the brain is a disease that develops in a person due to the accumulation of fluid in the ventricular system and other parts of the brain. The main factor in the development of internal hydrocephalus is the excessive development of spinal cerebrospinal fluid and its poor outflow in the future.

    This can happen for a number of reasons: because of injuries, if an infection has entered the body, with tumors in the brain. In the end, all this leads to accumulated fluid increasing the size of the human skull, thinning the walls of the ventricles of the brain, as a result of problems with the organ of vision, paralysis appears.

    If, with internal hydrocephalus of the brain, there are certain symptoms that a person can feel, then moderate internal hydrocephalus often does not make itself felt by any symptoms. Despite this, this disease prevents proper blood 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 it to chance. It is necessary to undergo a course of treatment under the supervision of a specialist. It is required to destroy all the factors that contributed to the appearance of the disease. When it is not possible to identify the source of the occurrence of moderate hydrocephalus, then it is worth taking steps to normalize the flow of blood in the brain. Usually a person has high intracranial pressure, the patient looks sluggish, has migraine and other unpleasant conditions.

    Internal hydrocephalus in adults

    Internal cerebral hydrocephalus usually occurs in young children, but there have also been repeated cases of this disease in adults.

    In adults, it is divided into two types:

    1. normotensive,
    2. internal hydrocephalus substitution.

    With this hydrocephalus, the process of removing cerebrospinal fluid from the skull is disrupted. This name was caused by the increase in fluid in the cerebral ventricles. But this name is not entirely justified, since the pressure of this liquid in the brain periodically increases. Often the disease develops as a result of concussions, surgical intervention, strokes.

    Internal hydrocephalus substitution is a type of disease in which, due to various reasons, the brain volume is significantly reduced, and the rest of the space is filled with cerebrospinal fluid. Employees of Novokuznetsk Research Institute, checking blood circulation in the brain in patients with this type of disease, found the following: almost all of the surveyed patients were caused by cervical vertebral dysfunction, atherosclerosis, alcohol addiction and other negative factors. It is worth noting the decrease in the intensity of blood flow in the subjects. Scientists suggest that this is due to the slow operation of the brain. Specialists recommend the use of diuretics, as well as drugs that promote vasodilation.

    Open internal and external hydrocephalus

    Open internal hydrocephalus is a form of the disease characterized by the expansion of the ventricular systems of the brain and the spreading of cerebrospinal fluid to the cerebrospinal fluid system, without any obstacle, unlike the closed internal( occlusal), where in the outflow pathThere are obstacles that were formed due to various causes( swelling, trauma, etc.).



    Hydrocephalus is external and internal. In the case of an open external form of the disease, the subarachnoid space expands, and hydrocephalus overflows and there is a subsequent thinning of the brain substance. The clinical picture in this case is as follows: the size of the human head is unnaturally large, the seam diverges, the bones of the skull become thinner. The unnatural size of the head can be observed already in the prenatal period, it can affect the subsequent course of childbirth. Neurological disorders affect the coordination of a person, you can see on your arms, legs tremor, especially for small children. Appear quite clear traces of stagnation in the eye fundus region.

    External hydrocephalus is a separate nosological species or complication in brain pathologies, which often have tumors, stroke, infectious diseases and others. External hydrocephalus in humans manifests itself as follows: nausea, vomiting, acute headache, constantly tends to sleep. Allocate external congenital and acquired hydrocephalus. The first type of disease occurs due to some intrauterine damage to the brain or the development of vices. The second type is the cause of craniocerebral injuries or inflammatory processes. From other species it differs, first of all in that it is capable of not revealing itself, for example, in the elderly, external hydrocephalus arises against a background of high blood pressure or atherosclerosis.

    Internal asymmetric hydrocephalus

    The role of intracranial pressure plays an important role. Against the background of the development of the disease, the entire cavity of the ventricle is enlarged, this usually refers to the lateral sides, in which the volume of cerebrospinal fluid increases. Depending on the type of disease, an increase in the entire cavity of the ventricle can occur asymmetrically, with the occlusion of the holes in the aqueduct of the brain. Asymmetric ventricular changes are associated with any trauma or with cases of obstruction of the interventricular orifice. The growing enlargement of the ventricles causes the death of brain tissue, leading to a flattening of the gyri. This applies primarily to white matter.

    The gray matter of the brain remains unchanged and undergoes a change only in the most severe cases of hydrocephalus development. Atrophy of the nervous tissue in the disease occurs under the squeezing of the capillaries of the brain due to high intracranial pressure. Changes that occur in the brain tissues in hydrocephalus are not the only ones, the ependyma of the ventricles also change. This is especially true of vascular plexuses, which are later susceptible to atrophy and death of the epithelium.
