Increased intracranial pressure.
Our brain is surrounded on all sides of the liquid in which it is located in a suspended state. This position protects the delicate brain tissue from external influences and injuries. Fluid surrounding the brain is called cerebrospinal fluid or CSF. Intracranial pressure is the pressure of the CSF, as well as arterial, venous and interstitial (in the brain tissue) pressure. Normal levels of intracranial pressure largely determine the health and well-being.
Increased intracranial pressure may occur with increasing amount of liquor, while the CSF begins to exert increased pressure on the brain. This is an increase in blood flow to the brain (the extension of cerebral arteries) or swelling (edema) of brain tissue redistribution of CSF as a result of ousting him from certain places (tumors). Intracranial pressure may rise, and in violation of the outflow of blood from the cranial cavity (narrowing of the veins), etc. All of this may be due to a postponed traumatic brain injury, meningitis or encephalitis, congenital structural features of the brain and spinal cord, etc.
Depending on the degree of increase in intracranial pressure, a man can disturb the following symptoms: headaches, which are amplified in the second half of the night or by morning, the head is heavy in the morning; at very high pressures align nausea and vomiting, is a consequence of the fact that in a horizontal position cerebrospinal fluid isolates the active and the morning of the intracranial pressure rises; bouts of sweating, a fall or increase blood pressure, palpitations etc., often associated with changes in weather, in this case, the lower the atmospheric pressure, the higher the intracranial; fatigue, especially during mental stress, irritability, “bruises” (enhanced small veins) under the eyes.
To confirm the diagnosis of raised intracranial pressure, and identify its causes is an additional examination of the patient. First of all, it is necessary consultation by the ophthalmologist, who examines the fundus. Applied research of the brain using ultrasound (echoencephalograph), it does not give very specific data on increased intracranial pressure. Ultrasound examination of cerebral vessels may reveal a violation of venous blood outflow.
Live with increased intracranial pressure and an unpleasant and unhealthy. The human brain under the influence of pressure to work normally cannot, moreover, is a slow atrophy of cerebral white matter, and this leads to a slow decline in mental abilities, disruption of neural regulation of the internal organs (hormonal disorders, hypertension, etc). It is therefore necessary to take timely measures for the speedy normalization of intracranial pressure.
