Definition of Stroke
Stroke is the clinical term for non-traumatic disorders of blood circulation that occurs acutely in a focal area of the brain, which results in a state of ischemia and neurologic dysfunction, focal or global, which lasted more than 24 hours, or directly cause the death. In a matter of seconds and minutes, brain cells do not receive adequate blood flow more will die through a variety of pathological processes.Typically, stroke manifest as neurological deficits appearance suddenly, such as weakness or paralysis of movement, sensory deficits, or speech impairments may also.

Stroke is a medical disorder of blood flow to one part of the brain that causes neurological deficits. Clinically, stroke is characterized by a loss of brain function locally or globally that occur suddenly and are caused solely by the brain circulatory disorders. Neurological deficits occurred during the 24 hours or more, can be improved, persist, worsen or the patient died
General pathology Stroke
The brain is a network that has the highest rate of metabolism. Although the future held only about 2% of the whole body, the brain tissue using up to 20% of the total cardiac output. Cardiac output is used as a source of fulfillment of necessary glucose and oxygen to brain tissue metabolism.
Symptoms and signs of focal disturbance of brain function in stroke will appear according to the area of brain tissue with impaired blood flow. Thus, symptoms can often provide a good prediction of the location of the blockage in the blood vessels. Symptoms focal localized mainly found in the nature of ischemic stroke. While on hemorrhagic stroke, focal symptoms are often less obvious and less specific location prediction.
This relates to the nature of hemorrhagic stroke which generally occurs shortly brain bleeding complications, such as increased intra-cranial pressure, brain edema, compression of brain tissue and blood vessels, and blood that comes out in all directions so as to provide disruption of brain function in areas other than the occurrence of bleeding.
Most cases of ischemic stroke, with a history and physical examination neurology, will obviously obtained enough information to localize the lesion site and side door are of the brain. For example, lesions will be found on the side opposite (contralateral) of hemiparesis or hemisensory experienced by the patient. Symptoms of aphasia also be obtained when the lesion is located on the left side of the brain. Furthermore, it can also predict whether a lesion found in the circulatory system of the anterior or posterior cerebral circle of Willis, the circulatory system located at the base of the brain is the source of cerebral blood flow.
Based on the location of brain areas drained, a stroke in the posterior circulation system will provide symptomatic brainstem dysfunction, including coma, drop attacks (sudden paralysis without impaired consciousness), vertigo, nausea, vomiting, cranial nerve palsy, ataxia, and deficits sensoric and motoric they intersect (deficit on one side of the face and the body / limb contralateral side). Hemiparesis, hemisensory, and a deficit in the field of view can also occur, but these symptoms are not specific to stroke in circulation posteriol.
After the acute phase of stroke untreated, the patient requires immediate medical rehabilitation therapy. This is necessary because of the shape, problems, healing patterns, social situation, and the response to treatment varies in each patient's stroke and it is very necessary planning an individualized rehabilitation program. Some things that are common in the management of the medical rehabilitation of stroke patients: a holistic treatment, therapy with targeted disruption, environment and timing of therapy, psychosocial problems, and rehabilitation in the acute phase .
