What is the stroke and its consequences?
Stroke is a type of disorderblood circulation in the brain and spinal cord. As a result of this disorder, insufficient amounts of oxygen and nutrients are delivered to the nerve cells, which leads to the development of pathology. As a rule, nerve cells die after a stroke, and it is not possible to restore them.
Stroke and its effects are manifested in different ways. Sometimes visible clinical manifestations may not be present, but in other cases the symptoms are strongly pronounced. Distinguish between spinal stroke and cerebral stroke.
By the nature of circulatory disorders are distinguishedthe actual stroke, the cause of which is the rupture of the blood vessel due to too high blood pressure. The second variant of the development of events is a heart attack, which is most often caused by a blockage of the blood vessel, for example, cholesterol plaques or detached microthrombi.
How can it appear externallystroke and its consequencesfor a person?
When one of the divisions of the brain is injured, the human body ceases to obey him. The nature of the manifestations of stroke will depend on the location of the violation.
As a rule, the main sign of a stroke is loss of motor activity, manifested by paralysis of the extremities or paresis. Paralysis is complete immobility, and paresis is partial.
Very often stroke and its consequences canmanifestations of speech disorders, while the possibility of hearing in patients is preserved. But there are also more complex cases when a person can not understand at all what the people around him are saying, he seems to be in another country or another reality.
With complex lesions of the centers of the brain,responsible for speech, when a person can not pronounce even individual sounds, he can forget how to write and read. This makes him completely helpless and puts on the level of an unthinking child.
When the visual centers are damaged, a person either ceases to see at all, or visual amnesia develops. That is, he can see, but do not recognize familiar faces or familiar surroundings.
Other consequences of stroke include:
- violation of touch;
- lowering the threshold of pain sensitivity;
- lack of temperature sensitivity: a person ceases to feel cold or warm;
- violation of orientation;
- violation of coordination of movement;
- memory disorder.
In turn, the spinal stroke and itsthe consequences are manifested mainly by the loss of motor activity of those parts of the body and the disruption of the work of those organs and systems for which the spinal column in which the hemorrhage occurred earlier was responsible. Violations of psychomotor functions with this type of stroke are not observed.
The question of how many live after a stroke,far from unambiguous. Everything will depend on the proper treatment and care for the patient. In addition, not the last role in the recovery is played by the person himself, only his faith and the applied efforts will be able to put on his feet and return to normal and full life.
