Stroke cerebral edema
Hemorrhagic stroke (hypertensive intracerebral haemorrhage) - is a cerebral infarction, which is characterized by the outflow of blood from the vessels of the brain into the brain substance, which leads to a violation of the blood supply to brain tissue, edema of the brain.
Hemorrhagic stroke can be caused by the following reasons:
- The main cause of hemorrhagic strokeis hypertension and associated with it microangiopathy (thinning of the walls of blood vessels). When the arterial pressure rises, the walls of these blood vessels break with the formation of intracerebral hematomas or hemorrhagic impregnation of the blood components of various parts of the brain. Such hemorrhages are called hypertensive (primary).
- Secondary hemorrhages are less common, theyare caused by rupture of vascular malformations. Arteriovenous malformations are a congenital anomaly of the development of the cerebral vascular system and represent different shapes and sizes of the coil that are formed by the disorderly interlacing of pathological vessels. Arteriovenous malformations cause a hemorrhagic stroke in 1/10 patients. The gap usually occurs between the ages of 20 and 40 years.
- Hemorrhages in the brain tumor can occur under the guise of hemorrhagic stroke
- Blood clotting disorders. various blood diseases (eg, leukemia) can begin with a hemorrhagic stroke clinic.

After intracerebral hemorrhage developsswelling of the brain. Due to the breakdown of blood and the reaction of brain tissue to the products of blood decay, inflammation and necrosis of brain tissue occurs. Thus, the damaged parts of the brain stop working and accordingly, the parts of the body that are controlled by this area of the brain will not work.
The consequences of hemorrhagic stroke are similar in many respects to ischemic stroke. people can experience:
- Movement disorders, weakness or paralysis - this can lead to difficulties during movement, walking and coordination. Movement disorders on one side of the body are called hemiparesis or hemiplegia.
- Violation of the swallowing. Violation of the act of swallowing can lead tothe ingress of food and liquid not into the esophagus, but into the respiratory throat and lungs, thereby causing a severe inflammation of the lungs. Violation of swallowing can also lead to constipation and dehydration of the body.
- Violation of Speech. Violation of the reproduction and understanding of speech, including difficulties in reading, writing, counting, occur as a result of damage to the left hemisphere of the brain.
- Problems of perception. At normal sight the person not in a conditionunderstand what he sees. Disturbances of perception make it difficult for a person to use everyday objects. For example, a person can not take a glass and pour water into it and then drink it.
- Cognitive impairment. The ability to mental perception andprocessing of external information. Violated clear and logical thinking, memory worsens, the ability to learn, make decisions and plan ahead is lost.
- Violations of behavior. There may be aggression, a slow reaction, fearfulness, emotional instability, disorganization.
- Violation of urination and defecation. Difficulties with the intestine or bladder (urinary incontinence or retention, incontinence) can be caused by a variety of different problems after a stroke.
- Psychological disorders. Sharp mood swings, depression,irritability, causeless laughter or crying. Depression is a very common problem in people who have suffered a stroke and is often accompanied by loss of appetite, causeless laughter or crying, insomnia, low self-esteem and a heightened sense of anxiety ...
- Epilepsy develops in 7-20% of people who have suffered a stroke.
- Pain syndrome. After a stroke in a small number of people, develop painful attacks in the form of burning, shooting, pulsating pain, which is not removed with anesthetic drugs.
In Russia, for hemorrhagic strokecharacterized by the highest rate of disability among survivors, which reaches 75%. Mortality and disability among all subgroups of acute disorders of cerebral circulation.
If the cause of the hemorrhagic stroke is not identified and, accordingly, the appropriate treatment is not selected, the probability of a repeated and sometimes fatal hemorrhage to the brain is extremely high.
Detailed and in-depth diagnosis of the causes of development,early recovery from stroke and rehabilitation after a hemorrhagic stroke contribute to the return to normal life of millions of people who have undergone Hemorrhagic stroke.
The main cause of hemorrhagic stroke is hypertensive disease.
Correctly selected therapy of hypertension, normalization of blood pressure contribute to the prevention of repeated cerebral hemorrhages.
If the cause of hemorrhagic stroke wasbleeding from arteriovenous malformation, and if this disease has not been diagnosed, then the probability of another and fatal hemorrhage to the brain becomes almost one hundred percent. Timely recognition of arteriovenous malformation and its surgical treatment returns a person to a normal life.
