Ischemic stroke, otherwise( acute disturbance of cerebral circulation of the ONMC) is a pathological condition that develops as a result of circulatory disorders in the vessels of the brain.
Blood flow disorder can be caused by vessel thrombosis, atherosclerotic lesion, spasm. Stroke - one of the most dangerous complications of diseases of the cardiovascular system.
Let's figure out what is the ischemic stroke of the left side, what are the symptoms and consequences of damage to this hemisphere of the brain, how many live and what is the treatment for a left-sided attack.
General information
The left hemisphere controls the functioning of the right half of the body , responsible for all kinds of sensitivity, motor activity, vision, hearing. Approximately 95% of humanity is right-handed, that is, their left hemisphere dominates the brain.
It houses the centers responsible for the application and perception of different types of speech, mathematical operations, logical, abstract, analytical thinking, the formation of dynamic stereotypes, the perception of time.
Symptoms of
The developing symptoms depend on the location and size of the lesion. They are divided into cerebral, vegetative and focal. With cerebral ischemia cerebral disorders are less pronounced than with hemorrhagic stroke, in some cases may be absent. The most common:
- sudden attack of severe headache;
- dizziness;
- loss of consciousness, with extensive lesions - coma of varying severity;
- nausea and vomiting;
- convulsions.
Any form of stroke is accompanied by the manifestation of focal symptoms, and their combination and severity are determined by the functional characteristics of the affected area. For left-sided stroke are characterized by:
- paralysis of the right side of the body of varying severity;
- violation of the right side of the body;
- impairment of sight, hearing, smell, up to the total loss of the ability to perceive the relevant stimuli. With severe lesions, the disorder can seize both sides;
- impaired sense of balance and coordination of movements;
- speech disorders.
Suspicion for an attack and first aid
Stroke refers to the emergency conditions of , pathological changes in the lesion develop in a matter of minutes. The faster the patient will receive medical care, the more likely a successful outcome.
If your attention was attracted by a person with a strange gait, an unnaturally asymmetrical face, you should:
- Speak to him . In a left-sided stroke, speech is illegible, a person is not able to identify himself, place, time, does not understand the question or can not say a word.
- Asking to smile or stick out your tongue. Asymmetry of the face will increase, with lesions of the left hemisphere, the movements of the facial muscles of the right half of the face are greatly hampered.
- Asking to raise your hands .On stroke indicates impaired mobility of the right arm.
Detection of even one of the symptoms is a sufficient basis for an emergency call of the "First Aid" about the suspicion of a stroke. Before the arrival of the physicians it is necessary:
- To lay the victim on his side, placing something soft under his head to protect the person in case of possible seizures;
- Ensure airflow;
- Unbutton, loosen, if possible - remove all parts of clothing that impede breathing;
- If it is possible to measure pressure, an antihypertensive drug can be given only if the victim is conscious and carries a medication previously prescribed by the doctor;
- When seizures develop, open the mouth to the patient;
- If you stop breathing or heart - start resuscitation.
We bring to your attention a video about what a stroke is and how to provide first aid in an attack:
Therapy
Treatment of an ischemic stroke begins directly at the site of .Emergency measures depend on the severity of the patient's condition and are primarily aimed at stabilizing the condition for transportation to a specialized department.
Immediately after hospitalization, studies are conducted to determine the overall physical condition of the patient, the location and size of the lesion. The basic treatment for ischemic strokes is aimed at restoring blood circulation in the affected area, maintaining and restoring the vital functions of the body, preventing possible complications.
Within a few hours after the onset of an attack, a thrombolytic drug is administered to the patient to dissolve the thrombus. At the end of this period, thrombosis can be eliminated only surgically. Patient is assigned funds that improve blood microcirculation, vasosolidifying drugs for normalization of blood circulation.
To restore and normalize metabolic processes in brain tissues, neurotrophic agents are prescribed.
As part of prophylaxis of thrombotic complications, antiplatelet agents , anticoagulants and blood flow improver drugs are prescribed.
Simultaneously, background disease is treated and symptomatic treatment of possible complications from vital organs is carried out.
The most dangerous early consequences of stroke are cerebral edema, coma and a second stroke, which are the most common cause of death in acute patients.
The degree of severity of residual neurological lesions varies greatly, ranging from minor speech disorders and motor functions to a complete loss of mobility, ability to minimize self-care. After a stroke, there are mental disorders, memory disorders, speech disorders .
Stroke of the brain stem - is it possible to recover? Read about it in a separate article on our website. On the extremely rare spinal stroke, about its symptoms, diagnosis and treatment, we have a lot of information in this article.
About recovery, predictions and consequences after a stroke of the cerebellum, you will learn here.
Prognosis for life
The forecast for a stroke is generally rather unfavorable, the possible consequences of each individual case are extremely difficult to predict, even after a complete examination of the patient. The prognosis worsens for elderly people , and also in the presence of some chronic diseases.
According to statistics, early complications of ischemic stroke are responsible for the death of about 25% of patients within a month after a stroke.
Approximately 60% have disabling neurological disorders.
Survival during the year approaches 70%, within five years - about 50%, a ten-year threshold is overcome by about 25% of surviving patients. Repeated strokes occur within five years of the first episode in approximately 30% of patients.
There are specially developed methods for assessing the risk of re-impact.
Recovery period
The recovery period after a stroke lasts up to three years. Patients are prescribed a diet, depending on the condition and availability of background diseases, massage courses, therapeutic gymnastics. The sanatorium treatment is shown. Patients are assigned maintenance therapy, often lifelong.
More specific recommendations can be given only by the attending physician, who has full information about the features of the course of the disease and the general condition of the patient.
There is a lot of useful information about recovery after the disease:
