A cerebrovascular accident, more commonly known as a stroke, occurs when the blood supply to determined parts of the brain suddenly ceases. This may be due to the occlusion of a cerebral vessel, in which case the patient suffers an ischemic infarction, or due to the rupture of a blood vessel. The latter leads causes a hemorrhagic stroke.
Annually, more than half a million individuals in the USA have a first cerebrovascular accident. In 1990, cardiovascular disease accounted for more than 14 million deaths in a population of 5.3 billion or 29% of the world’s 50 million deaths. Of these, 6.3 million deaths were due to CHD and 4.4 million were caused by cerebrovascular accident.
Cerebrovascular disease includes a variety of medical conditions that affect the blood vessels of the brain and the cerebral circulation. Arteries supplying oxygen and nutrients to the brain are often damaged or deformed in these disorders. The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke.
A stroke, or cerebrovascular accident (CVA), is the rapid 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).
Cerebrovascular accidents (CVA) or stroke are a common and serious neurologic event in the elderly. The residual effects can be permanent or temporary and vary in their morbidity. These impairments.
The global burden of cerebrovascular disease Thomas Truelsen1, Stephen Begg 2, Colin Mathers2 1. Introduction The 1990 Global Burden of Disease (GBD) study provided the first global estimate on the burden of 135 diseases, and cerebrovascular diseases ranked as the second leading cause of death after ischemic heart disease 1.
