The human brain is designed in such a way that the impulses of the right hemisphere control the left side of the body and, conversely, the left - right. With normal functioning, both hemispheres work in a balanced manner, complementing each other. Characteristic disorders that occur with the disease, differ depending on whether there was a stroke of the left side or right. From the left hemisphere depends the development of logical thinking, from the right hemisphere - imagery, emotionality in the perception of life. The analysis of events taking place in time occurs in the left hemisphere with the subsequent synthesis in the right. Consequently, the left is inherent in the processing of new information, and it is inherent to the right to recognize the already familiar. The fusion of the two "I" - the sentient and the speaking, the emotional and the logical and determines the consciousness of the person.
What are the difficulties of diagnosing left-sided stroke?
When there is a rupture of the vessel in the right hemisphere, there is a stroke - paralysis of the left side. Right hemispheric stroke is more difficult to diagnose early, because usually the patient's speech remains unchanged, unlike stroke in the left hemisphere. As a result, precious time can be lost, according to neurologists, if the doctor has time to examine the victim within three hours, then a quick cure is possible, otherwise, there are consequences that significantly change the quality of a person's life, regardless of which hemisphere There was a stroke. Thus, the stroke of the left side is really more difficult to diagnose and timely hospitalization, later adequate treatment is prescribed.
The main features of the left stroke stroke
In the case of a right hemispheric stroke, the following violations are observed:
• Left-sided paralysis of the body
• Impaired perception / sensation
• Loss of memory for current actions (with saving the memory to the past)
Stroke of the left side generates disturbances in spatial perception. Those who are ill can not relate parts to the whole, the ability to evaluate forms, the dimensions, the speed of movement in transport, the perception of one's own body is lost. The person becomes extremely complacent, he does not care about the violation of motor functions, he calmly tolerates the defects that appear, he does not hurry to fix them, simply not noticing them. This is why a left-sided stroke is fraught with prolonged immobilization of a patient who does not seek to restore motor functions due to passivity, recovery is slower than with left hemisphere stroke. This is the specificity of the course of the disease, which in no case can be taken for the laziness of the patient.
Difficulties arising from impaired perception / sensation
Patients with a distorted perception of their own body most often do not feel their left arm. Sometimes there is a loss of sensation of separate parts or of your body as a whole, there is a feeling of alienation of the left side of the body (sensation of someone else's body). A feeling may arise of several paralyzed hands or feet, instead of one with distortion of their shape and size. Stroke of the left side creates difficulties in the violation of spatial perception - it is difficult for such patients to ride a wheelchair even with the most concentrated attention through a rather large doorway. It is difficult for them to determine visually the distance to objects, they incorrectly put on clothes, skip buttons, they are forbidden to sit behind the wheel of a car.
Patients with left-sided stroke do not realize the extent of their disease, they have depression accompanied by mental passivity. They have intuitive actions, as a result of which they can cause harm not only to themselves, but also to surrounding people. When caring for patients with left-sided stroke, it is necessary to warn them against actions that exceed their capabilities and are accompanied by a risk. Patience, caring care, timely inpatient treatment, exercise and time will help in the recovery and recovery of all body functions.
