Ischemic stroke
Ischemic stroke (IS) is a cerebral infarction that occurs as a result of blood flow cessation to the brain. IS develops when the lumen of the cerebral blood vessel closes, which leads to a cessation of blood supply to the brain. Also, supply of both oxygen and nutrients, which are necessary for the normal functioning of the brain, are ceased as well.
Causes
IS can be caused by the following conditions:
- Atherosclerosis of the arteries of the head and neck
- Arterial hypertension with damage to the small cerebral arteries
- Diabetes
- Heart rhythm abnormalities with the formation of blood clots in the heart cavities

Consequences
The brain is an extremely complex organ that controls various functions of the body. If the blood can not reach the brain regions that are responsible for functions of certain parts of the body, these parts of the body will stop functioning properly.
After an ischemic stroke, people can experience:
- Motor disorders, weakness or paralysis - this can lead to difficulties in movements, walking and coordination. Movement disorder on only one side of the body is called hemiparesis or hemiplegia.
- Swallowing disorder. Swallowing disorder can cause food and liquid not getting into the esophagus directly, but getting into the respiratory tract and lungs. This can cause severe inflammation of the lungs. Swallowing disorder can also lead to constipation and dehydration.
- Speech disorder. Problems with reproduction and understanding of speech include difficulties in reading, writing and counting. They can occur as a result of damage to the left hemisphere of the brain.
- Perception problems Even with the normal vision, the person is not able to understand what he/she sees. Perception disorder makes it difficult for a person to use everyday objects. For example, person can`t take a glass, pour water into it and then drink it.
- Cognitive disorder In this case the ability to mentally percept and process external information is violated. Clear and logical thinking is distorted, memory of the person starts to deteriorate, the ability to learn, plan and make decisions is lost.
- Behavior disorder The person can experience aggression, slow response, fearfulness, emotional instability and disorganization.
- Bladder and bowel problems ТStroke can cause a variety of different problems, resulting in either bowel or bladder dysfunction (urinary incontinence or retention, fecal incontinence).
- Psychological disorders These include mood swings, depression, irritability, episodes of laughing or crying without an evident reason. Depression is a very common problem for people who have suffered stroke. It is often accompanied by loss of appetite, episodes of laughing or crying without a reason, insomnia, low self-esteem and an increased sense of anxiety.
- Epilepsy The number of stroke patients who eventually develop epilepsy ranges from 7% to 20%.
- Pain syndrome A small number of stroke patients can develop pain episodes manifested in burning, shooting and throbbing pain, which cannot be relieved with painkillers.
Risk of Recurrent Stroke
20% of people who have suffered ischemic stroke die within the first month and about 25% of them die within the first year.
Within the next 5 years, more than half of the surviving patients suffer the second stroke, with most cases occurring in the first year after an episode.
In Russia, about 100,000 cases of recurrent strokes are registered on average each year. Six months after the stroke, disability develops in 40% of surviving patients.
Within the first 5 years, up to 85% of patients either die or remain disabled and only the remaining 15% of patients manage to recover.
How to live after Ischemic Stroke?
In Germany and other countries of the European Union, ischemic stroke is not a diagnosis that condemns people to deep disability and death.
With a detailed and in-depth diagnosis of causes of ischemic stroke, early recovery from the effects of ischemic stroke and rehabilitation, millions of people who have suffered the condition can return to their normal life.

Scientists succeeded in identifying a genetic mutation in one of 23,000 human genes, which increases the risk of stroke by 42%.
According to statistics, the annual number of strokes in Russia accounts for 400,000, whereas about 80% of these are ischemic strokes, 15% – hemorrhagic and 5% - subarachnoid hemorrhage. The mortality rate in all types is quite high: 20% to 40% of patients die within the first month.The causes leading to such disorders have not yet been precisely identified. However, there is a variety of factors that can influence the development of stroke. These include arterial hypertension, heart disease, smoking, high cholesterol levels in the blood, excessive intake of salt. In addition, one of the important components affecting the healthy state of the body is proper nutrition. Researchers have studied how various foods can influence the risk of development of this condition. It was found that the consumption of low-fat dairy products can significantly reduce the risk, as compared with fatty milk, yogurt and cheese.
The Letter-Number Sequencing Test will help to predict the risk of death in older people who have already suffered one stroke in the past.
Scientists found that the rehabilitation period in patients who had stroke and took anti-thrombotic drugs proceeds much faster and without any visible complications.
Honey is a product that consists of the most easily digestible sugars: fructose and glucose. These substances are absorbed without any additional processing. Their digestion does not need the involvement of organic acids, nitrogenous substances, vitamins and minerals. These are the properties of honey that are widely used in medicine.
During the research, the scientists concluded that aggressive behaviour can increase the risk of stroke twice, while quick temper, impatience and aggression affect the condition of the organism just the same way as smoking does.
At the moment, there is no single hypothesis about the mechanism of stroke development. It was suggested that most strokes developed due to the narrowing of one of the two carotid arteries. Nonetheless, if brain has a special circulation that provides a normal blood supply to the brain tissues, even in the case of complete blockage of one of the arteries, this theory cannot be applied. The currently prevailing approach involves both identification and study of risk factors (a set of circumstances correlating with the development of stroke).
With the consumption of chocolate, many people can avoid stroke in their old age. Many researches have already shown that stroke is manifested as an impaired cerebral circulation that damages brain tissues and causes disorders of its functions, which can further result in a complete or partial immobility, speech, memory and psychological disorders. There are many causes that affect the development of the condition. These include hypertensive heart disease, atherosclerosis, heart diseases, rheumatism and others.Taking into account the severity and complexity of the disease, specialists strongly advise to pay attention to both preventive measures and lifestyle. The list of the most simple preventive measures includes not smoking and drinking alcohol, prevention of obesity, having active lifestyle and proper nutrition. In addition, there are other factors that can reduce the risk of stroke. One of these components was discovered during the recent study.
From the point of view of ecology, cedar oil is the purest of all existing vegetable oils. It surpasses the majority of healthy foods in taste, nutritional value, microelement and vitamin composition.
A deep study of night sleep in patients diagnosed with "cerebral stroke” (CS) is not only of purely academic interest. It also has a serious practical importance for prognosis, as well as for therapeutic and rehabilitative activities. It has already been found that sleep disorders are one of the etiological factors of CS. The structure of sleep in the patients with CS also reflects minor, almost undetectable clinical changes in the hemodynamics of the brain, which can be either negative or positive. If patient in coma has individual elements of sleep, namely, periods of desynchronization accompanied by rapid eye movements combined with a decrease in muscle tone, it eloquently testifies to the relative preservation of the stem and diencephalic structures of the brain, which is a favourable prognostic factor.
