Stroke is a type of circulatory disturbance in the brain and spinal cord. As a result of this disorder, an insufficient amount of oxygen and nutrients is 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 consequences are manifested in different ways. Sometimes there may be no visible clinical manifestations, and in other cases the symptoms are very pronounced. Distinguish spinal stroke and cerebral.
According to the nature of circulatory disorders , the stroke itself is distinguished , the cause of which is a rupture of a blood vessel due to too high blood pressure. The second scenario is a heart attack, which is most often caused by a blockage of a blood vessel, for example, cholesterol plaques or a detached microthrombus.
How can a stroke and its consequences for a person appear externally ?
When one of the parts of the brain is damaged, the human body ceases to obey it. The nature of the manifestations of the stroke will depend on the location of the violation.
As a rule, the main sign of a stroke is a loss of motor activity, manifested by paralysis of the limbs or paresis. Paralysis is complete immobilization, and paresis is partial.
Very often, a stroke and its consequences can be manifested by impaired speech, while the ability to hear in patients remains. But there are more complicated cases when a person is completely unable to understand what others are telling him about, 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 cannot make even individual sounds, he can forget how to write and read. This makes him completely helpless and puts him on the level of an unconscious child.
When the visual centers are damaged, a person either ceases to see at all, or he develops visual amnesia. That is, he can see, but not recognize familiar faces or familiar surroundings.
Other effects of a stroke include:
- violation of touch;
- lowering the threshold of pain sensitivity;
- lack of temperature sensitivity: a person ceases to feel cold or heat;
- disorientation;
- violation of coordination of movement;
- memory disorder.
In turn, spinal stroke and its consequences are manifested mainly by loss of motor activity of those parts of the body and disruption of the functioning of those organs and systems for which the spine section in which the hemorrhage occurred was previously responsible. Violations of psychomotor functions with this type of stroke are not observed.
The question of how much they live after a stroke is far from an unambiguous one. Everything will depend on the right treatment and patient care. In addition, the man himself plays an important role in recovery, only his faith and efforts will be able to put him on his feet and return to a normal and full life.
