Stroke occurs in violation of the delivery of oxygen to different areas of the brain.In ischemic variant it is associated with reduced blood flow, and in hemorrhagic - hematoma with compression of the nerve tissue.Since neurons are very sensitive to hypoxia, a few minutes begin irreversible changes.Further, in the lesion nerve cells are replaced by connective tissue, and sometimes cysts are formed, filled with liquid contents.In this case the lost functions may take over part of the surrounding nerve fibers, but often observed complete loss of any action.
stroke Consequences vary depending on the size of the lesion, the area of origin.With timely and adequate treatment started rehabilitation treatment, functional recovery occurs in a large percentage of cases.
various movement disorders often occur in the brain stroke.This interrupts the connection between the cortical structures and muscle fibers.With the full momentum transfer termination developing plegia, or paralysis, with
According to some scientists paralysis is accompanied by no less than 80% of cerebral blood flow in acute period, while it is a major factor leading to the patient's disability.It should be noted that after the second stroke, motor functions are restored in fewer cases, as with the lesion, usually greater.
Often when the motor effects of a stroke develop an increased tone in some groups of muscles, abnormal reflexes (eg Babinski) and abnormal movements friendly.Further, the limb is fixed in position, there is restriction of its movement and the development of contractures.To avoid these changes, you must at the earliest time frame to start the rehabilitation of the patient, which is to perform massage, physical therapy and physiotherapy.
In the early stages after a stroke should begin rehabilitation of the patient with the help of physiotherapy
Violation of speech and swallowing
speech disorders after stroke is associated with impaired blood supply to the middle cerebral artery.At the same time the leading hemisphere is usually involved, ie right-handers such changes develop stroke left.
Depending on the nature of the lesion can develop sensory or motor aphasia.In the first case, the patient is unable to perceive surrounding it while he can speak meaningless sentences.A person can read but not understand what they read.In motor aphasia patient understands it, but he can not speak and write.
Interestingly, the effects of the primary lesion is possible to eliminate virtually 100% of cases, while not such bright prospects in the second stroke.
Possible signs of stroke in men
Frontal syndrome develops when a change in the basin of the anterior cerebral artery.It is characterized by a decrease in self-control, irritability and egocentrism.Man no longer care about the surrounding and close people, it becomes less emotional and inhibited.This is not always the memory of suffering and patient intelligence.
psychopathological syndrome, characteristic of the right side of the stroke, when involved in the process of middle cerebral artery, on the contrary, accompanied by a loss of orientation in space and its own personality, forgetfulness and declining mental abilities.
When changes in the posterior cerebral artery often develop a variety of visual impairment.The most common diplopia (double vision), hemianopsia (blindness for half the eye), strabismus, in which one or both eyes deviate from the central axis.Thus at the right hemisphere stroke usually develop visual field loss on the left side, this is due to the fact that the optic nerves in the brain form a chiasm (chiasma).
stroke brainstem oculomotor disturbances develop.When in the process involves the vascular and respiratory center, located in this area, the patient loses the ability to breathe, and it becomes unstable hemodynamics.In this case, you must connect it to a respirator and maintain blood pressure and heart rate using a continuous intravenous sympathomimetics (adrenaline, dopamine, phenylephrine).Prognosis is poor at a given location.
Vestibular disorders may develop in lesions in the brain stem or pyramid, but are more common in stroke cerebellum.Symptoms of this condition is the dizziness that occurs when changing body position in space, nystagmus (rapid eye movement horizontally or vertically), the imbalance.In addition, with the defeat of the cerebellum there is nausea and vomiting of central origin, as well as muscular hypotonia, and ataxia (impaired movement coordination).Often to the vestibular manifestations joined the reaction of the autonomic nervous system, characterized by a change in blood pressure and heart rate, respiration rate, sweating, and the advent of a rush of blood to the vessels of the face.
consequences of stroke treatment is a very important task which needs to be addressed at the earliest stages of the disease.Because the more time has passed from the time of damage to the nervous tissue, the less the chance of at least partial recovery of lost functions.The most common disability in ischemia or hemorrhage into the brain cause motor disturbances that develop on the opposite side of the lesion.To prevent the development of irreversible changes should begin rehabilitation therapy at the earliest possible time.
