What is a stroke?
A stroke, previously known medically as a cerebrovascular accident (CVA), is the
rapidly developing loss of brain function(s) due to disturbance in the blood supply to the
brain. This can be due to ischemia (lack of blood flow) caused by blockage (thrombosis,
arterial embolism), or a hemorrhage (leakage of blood). As a result, the affected area of
the brain is unable to function, leading to inability to move one or more limbs on one side
of the body, inability to understand or formulate speech, or an inability to see one side of
the visual field.
[2]
A stroke is a medical emergency and can cause permanent neurological damage,
complications, and even death. It is the leading cause of adult disability in the United
States and Europe and it is the number two cause of death worldwide. Risk factors for
stroke include advanced age, hypertension (high blood pressure), previous stroke or
transient ischemic attack (TIA), diabetes, high cholesterol, cigarette smoking and atrial
fibrillation. High blood pressure is the most important modifiable risk factor of stroke.
A stroke is occasionally treated in a hospital with thrombolysis (also known as a "clot
buster"). Post-stroke prevention may involve the administration of antiplatelet drugs such
as aspirin and dipyridamole, control and reduction of hypertension, the use of statins, and
in selected patients with carotid endarterectomy, the use of anticoagulants. Treatment to
recover any lost function is stroke rehabilitation, involving health professions such as
speech and language therapy, physical therapy and occupational therapy.
Classification
Strokes can be classified into two major categories: ischemic and hemorrhagic. Ischemic
strokes are those that are caused by interruption of the blood supply, while hemorrhagic
strokes are the ones which result from rupture of a blood vessel or an abnormal vascular
structure. About 87% of strokes are caused by ischemia, and the remainder by
hemorrhage. Some hemorrhages develop inside areas of ischemia ("hemorrhagic
transformation"). It is unknown how many hemorrhages actually start as ischemic stroke.
Signs and symptoms
Stroke symptoms typically start suddenly, over seconds to minutes, and in most cases do
not progress further. The symptoms depend on the area of the brain affected. The more
extensive the area of brain affected, the more functions that are likely to be lost. Some
forms of stroke can cause additional symptoms. For example, in intracranial hemorrhage,
the affected area may compress other structures. Most forms of stroke are not associated
with headache, apart from subarachnoid hemorrhage and cerebral venous thrombosis
and occasionally intracerebral hemorrhage.
