It should be said that hypertensive cerebral crisis refers to one of the types of hypertensive crisis. Very often, its development is observed against the background of an already existing hypertension with an accompanying increase in the load on that part of avodart pills that is responsible for the tone of the cerebral vessels.
Classification of hypertensive cerebral crisis.
Depending on the mechanism of development of pathological abnormalities against the background of arterial hypertension in the vessels of the brain, experts distinguish the following types of this disease.
The angiopathic type of hypertensive cerebral crisis occurs due to reduced vascular tone in the brain. In addition, its appearance is affected by the deposition of blood in the venous system, which is manifested by increased intracranial pressure.
This condition can also occur with the development of other diseases that contribute to an increase in blood pressure. For example, very often a hypertensive cerebral crisis occurs with.
In fifty percent of all cases, a hypertensive cerebral crisis will be a consequence of a stressful state. Other external factors that contribute to the disruption of the normal functioning of the cerebral vessels are sudden changes in weather, excessive physical fatigue, hypothermia, malnutrition or overeating.
The prerequisite for an ischemic type of crisis is oxygen starvation of the layers of the brain, which occurs due to a sharp reflex spasm of avodart pills online in the brain as a response to an increase in blood pressure. A complex type of hypertensive cerebral crisis is a combination of the above two mechanisms. There is another classification of hypertensive cerebral crisis - depending on the presence of complications, they are isolated. Hypertensive cerebral crisis is dangerous for its complications, including ischemic stroke, transient ischemic attack, rupture of cerebral aneurysm, and so on. In pregnant women, eclampsia will be a frequent manifestation of this disease.
Pathogenesis of hypertensive cerebral crisis. In a healthy state of the human body, the regulation of blood circulation in the brain works according to the following principle. when blood pressure rises, there is an increase in the tone of the cerebral arteries, which helps to avoid excessive blood flow to buy dutasteride online. If this mechanism is violated, then the manifestation of a tonic reaction of dutasteride pills of the brain in an excessive or insufficient form is possible.
If the tonic reaction of the cerebral vessels in the event of an increase in blood pressure is insufficient, a blood breakthrough into the vessels of the brain is possible. However, even here the protective reaction of the body is activated in the form of a second compensatory mechanism, which should increase the tone of the venous vessels. When working properly, this mechanism accelerates the outflow of excess blood from the cranial cavity. If, however, a failure of the mechanism is traced here, then an angiohypotic type of hypertensive cerebral crisis develops, which is based on stagnation due toaccumulation of excessive fluid in the skull.
If, in response to a jump in blood pressure, the tone of the arteries also increases, then this can lead to disruptions in the blood supply to the brain tissues with the further development of oxygen starvation (hypoxia), which will entail an ischemic type of hypertensive cerebral crisis. First of all, the cerebral cortex will suffer, so as it is most sensitive to order dutasteride pills. The uneven structure of the cerebral vessels leads to local angiospasm, which affects the occurrence of foci with pronounced ischemia.
