Intracranial hypertension is called intracranial pressure, the symptoms of which periodically tests 70% of the adult population. It should be noted that the intracranial pressure (ICP) in itself is not a disease but a symptom of some infectious diseases, neurological diseases of the brain, tumors and more of a number of pathologies characterized them. In order to clarify the picture slightly consider brain anatomy buy capoten online.
The well-known fact that the brain - is the most important organ that regulates the operation of all aspects of human life. That is why the brain is protected by three membranes to ensure its maximum safety: it is soft, hard and arachnoid. To ensure the functioning of the brain is produced from human blood cerebrospinal fluid - the fluid, which is under constant pressure, and performs several vital functions:protecting the brain from mechanical damage to the skull; provision of water and electrolyte balance; providing body power.
The volume of CSF is about 10% of the total content of the cranium. The liquor produced from the blood, passes through special channels, bathing the brain and gets back into the blood, where dissolves. As a result, some of the pathologies at one stage may fail, resulting in the increase of CSF pressure on the brain, and then the person begins to experience symptoms of intracranial pressure.
ICP symptoms in adults can vary depending on various functional effects on brain centers:
Strong arching headache. Feeling worse on motion, tilt and swivel head;
Visual impairment. Manifest misting, split, lack of reaction of the pupil to light. There is a stagnation of the optic nerve, eye redness due to overcrowding in the veins due to blood stasis;
Podglaziny. Arise due to the overflow of veins under the skin;
Nausea. Leaking or no vomiting, or is accompanied by gushing vomiting, not bringing relief;
Disorders in the autonomic system. Manifest chills or excessive sweating;
Emotional instability. It arises as a result of compression of the hypothalamus - center responsible for emotions;
Lethargy, depression, concentration difficulty. As a result of compression of the cerebral cortex and the medulla oblongata observed inhibition of mental functions;
Paresis. Restriction of motor functions of one limb or one side of the body, symptoms resembling paralysis;
Dyspnea. The feeling of lack of air due to the compression of the respiratory center of the medulla oblongata;
Back pain (pressure increase in the spinal canal).
Particularly noteworthy are the signs of intracranial hypertension in children. A small child can not talk about their feelings, so it is important to notice the symptoms of ICP.
