CVA Causes The relationship between a stroke and cerebrovascular disease (CVD) is not fully understood. However, the symptoms of both diseases are similar. Strokes are usually caused by blood clots and they are called either “stenosis” or “cavernous venous disease”. On the other hand, strokes can also be caused by abnormal brain activity that is called cva. This brain dysfunction leads to a reduction in cerebral blood flow and eventually to the stroke.
A stroke can occur any time. A stroke usually occurs during a major event in life such as a car accident or violence in the home. CVA and stroke share some common risk factors, although the two diseases differ on many variables. Both diseases are characterized by an abnormal brain activity and reduced blood flow in the region of the brain that is affected.
As already explained, a stroke is caused by a blood clot or venous thrombosis in brain tissue. It usually occurs in a major accident or major incident such as surgery. A person with a history of stroke can develop a mild or serious embolus, which is a collection of blood fragments in brain tissue. Such fragments usually interfere with cerebral blood flow and this causes brain tissue death.

There are several types of strokes and the most common is the ischemic stroke, which is caused by the blockage of arteries and veins in the brain or the infarction of blood vessels in the brain. Another ischemic stroke is an embolus that occludes a large portion of a cerebral vasculature. Then, there is a ethmoid hemorrhage in the cerebral neck which is caused by a blood clot in the neck; an embolus in the inguinal region which is a collection of blood fragments in the inguinal canal, a embolus in the parietal region which is an embolus in the frontal brain region, and finally, a corpus vivax hemorrhage which is a collection of blood fragments in the brain.
There are various risk factors for developing this condition and they are age, gender, race, pre-existing medical conditions and family history. Moreover, there are some other factors such as stroke, head injury, or head trauma that can lead to the development of this condition. Some of the risk factors for ischemic stroke include: a history of stroke in the family; a personal or family history of severe hypertension; atherosclerosis; obesity; atherosclerosis on the cerebral arteries; congenital defects including left sidedness or right sidedness; and a history of alcohol abuse. Some of the risk factors for hemorrhagic stroke include: a history of stroke in the family; hypertension; a personal or family history of severe hypertension; congenital defects including left sidedness or right sidedness; and obesity.
A risk factor that can be determined by the medical records of a person is the timing of the first attack. Generally, the higher the age at the time of the first attack, the higher the chances of having this condition. On the other hand, the higher the age at the time of the first attack, the lower the chances of having this condition. Furthermore, if there was a history of thrombotic stroke, it means that the person is likely to have a thrombolytic stroke. Thrombolytic stroke can be brought about by the accumulation of plaques in the brain that blocked the flow of blood in the area.
