Hemorrhagic stroke, right side: effects

Hemorrhagic stroke is a vascular accident, in which the output of blood from the vessels into brain tissue. A severe pathological process that leads to the development of paralysis, disturbance of sensation and disability of the sick person. According to modern statistics, in the first month, the mortality reaches 10 to 12%.

The reasons for the development

The term «hemorrhagic stroke» determines the output of blood from the vessels into brain tissue. In this part of the cells of the nervous system (narocito) and nerve fibers in the pathological process is killed, which leads to severe disturbances or complete loss of function of the affected area. This pathological process most often affects the brain, the affected motor and sensory fibers and neurocity responsible for the implementation of the respective functions in certain areas of the body. There are several main reasons for the development of hemorrhagic stroke, these include:

  • Atherosclerotic disease of the blood vessels, which in their walls postponed cholesterol with the formation of atherosclerotic plaques. They reduce the lumen of the affected artery, but also cause increased brittleness of its walls to their damage and subsequent hemorrhage.
  • Congenital abnormality of arterial blood vessels, leading to significant weakness and fragility of their walls.
  • Expressed arterial hypertension (high blood pressure) is one of the main causes of hemorrhagic stroke (80% of all cases), due to the high pressure there is damage to the artery walls with subsequent hemorrhage.
  • Tumor vascular disorder characterized, that is formed by choroid plexus (malformation), consisting of arteries and veins with very weak walls.
  • Head injury (closed craniocerebral injury) is one of the causes of hemorrhage in young people, stroke is most often localized in the subarachnoid space (hemorrhage occurs in the space under the arachnoid sheath).

Regardless of the reasons for the development, the entry of blood into the structures of the Central nervous system leads to severe consequences associated with the loss of functional activity of the respective structures.

The effects of lesions of the CNS right

Anatomical and histological structure and the structure of the tissues of the brain differ in a characteristic feature of nerve – fibers have optic chiasm. This means that if affected the right side (hemisphere) of the brain, the manifestations of functional disorders will take place in the left half of the body. The main manifestations of the loss of the functional activity of the affected area tissues include motor and sensory disorders.

Doctors are shocked by the statement, the chief cardiac surgeon in the country Leo Beaucaire.

Movement disorders

Movement disorders, which develop in hemorrhagic stroke on the right depend on the severity of bleeding and the volume of the affected tissues. They can range from reduced muscle strength (weakness) lack the ability of conscious movements (paresis). Depending on the localization of bleeding such disorders can develop only in the left hand, leg, or completely immobilize the left half of the body (left sided hemiparesis), including facial muscles.

Sensory disorders

After a hemorrhage in brain tissue affected and die neurocity and nerve fibers that are responsible for the feelings of the person. While on the left side of the body dramatically reduced or absent skin sensitivity. The first to suffer tactile, pain and temperature sensitivity. Then attaches the absence of sensations proprioceptors (receptors in striated muscle and tissues of the joints), in which a sick person does not feel limbs. Sensory disorders of localization correspond to the motor. When you lose a significant amount of brain tissue missing sensitivity on the skin and in the tissues of the entire left half of the body.

The effects of stroke associated with damage to various centers

The cerebral cortex contains specific regions that are responsible for certain functions. In addition to motor and sensory disorders also can disrupt the person’s speech, his vision and sense of smell (due to destruction of the respective centres). Forecast the effects of lesions of the CNS to the right depends on the volume of the affected tissues. The smaller the number of narocito and nerve damaged, the better the forecast, while the lost functions partially take on the surrounding undamaged areas.
