Cerebrovascular Disease

In a cardiology we know one kind of disease called as cerebrovascular disease. Cerebrovascular disease is a kind of disease that refer to the many conditions that affect the circulation of blood into the brain, either it make limited flow or no blood flow affected areas of the brain. In general definition, Cerebrovascular Disease is the general term for a brain dysfunction caused by an abnormality of the cerebral blood supply. The cause of this disease may of some reason like high cholesterol level coupled with inflammation in the arteries in the brain to build up in the vessel in form of a thick, waxy plaque. This plaque can limit, or completely obstruct of blood flow to the brain and causing stroke.

Symptoms of Cerebrovascular Diseases

On early a cerebrovascular attack (CVA), the patient may experience flaccid paralysis followed by increased muscle tone and spasticity or may lose gag reflex and ability to cough, or may have communication deficits such as dysphagia, receptive or expressive aphasia, dysarthria and apraxia. He or she can loss of half of visual field (homonymous hemianopia) and inability of recognize an object (agnosia).

A symptom is something the patient senses and describes, while a sign is something other people, such as the doctor notification. The signs and symptom of cerebrovascular diseases are depending on the location of the hemorrhage, thrombus or embolus and the extent of cerebral tissue affected. General signs and symptoms of a hemorrhagic or ischemic event include motoric dysfunction.
Other signs and symptoms of CVA (cerebrovascular attack) include vomiting, seizures, fever, ECG abnormalities, confusion that leads to a complete loss of consciousness, labored or irregular respirations, apneic periods, increased blood pressure, severe headache, nuchal rigidity and rapid onset of complete hemiplegia. Patents of neurologic deficits worsen from gradual loss of consciousness to coma.

Symptoms of a thrombotic CVA can follow by stroke in evolution pattern and include the progressive deterioration of motor and sensory function, show deterioration of speech, and lethargy. Patient with an embolic CVA signs by a sudden onset of motor and sensory deficits, deteriorated speech, and headache on the side of the head where the embolism is occurring. If the embolus breaks into smaller pieces and the occlusion resolves, these signs and symptoms may dissipate.
