Cerebrovascular disease is a group of brain dysfunction associated with the disease the blood vessels supplying the brain. Hypertension is the most important causes, but damage the lining of blood vessels, the endothelium, exposing the underlying collagen to which platelets aggregate to begin the repair process is not always complete and perfect. Hypertension is sustained permanent architectural changes of the blood vessels making them narrower, stiff, deformed, uneven and more susceptible to fluctuations in blood pressure.
Decrease in blood pressure during sleep can lead to a marked reduction of blood flow in the narrowed blood vessels causing ischemic stroke in the morning. Conversely, a sudden increase in blood pressure due to the excitation during the day can cause tearing of the blood vessels so that the intracranial hemorrhage. Cerebrovascular disease mainly affects people who are elderly or have a history of diabetes, smoking, or ischemic heart disease. The results of cerebrovascular disease can include stroke, or sometimes hemorrhagic stroke. Ischemia or other vascular dysfunction can affect a person for cerebrovascular accident.
Each year, an estimated 158,000 people in the United States died from cerebrovascular disease. An estimated 30,000 people in the United States experienced a ruptured brain aneurysm, and to 6 percent of the population may be living with unruptured aneurysms. Aneurysms occur in all age groups, but the incidence continues to increase for individuals age 25 and older. Ruptured aneurysms are most prevalent at ages 50 to 60 people and about three times more common in women. Ruptured brain aneurysms are fatal about 50 percent of the time.
A form of cerebral aneurysm from weaker sections of the walls of blood vessels, resulting in a bulging or ballooning out of part of the vessel wall. Usually, aneurysms develop at the point where the branches of blood vessels, because the 'fork' is structurally more vulnerable. The disorder can result from congenital defects or from other conditions such as high blood pressure atherosclerosis (the build-up of fatty deposits in arteries), or head trauma. People who suffer from ruptured brain aneurysm (subarachnoid hemorrhage) may have warning signs such as severe headache, nausea or vomiting, stiff neck, blurred or double vision, sensitivity to light (photophobia), and loss of sensation. Unruptured aneurysms, however, may be asymptomatic.
Actress Sharon Stone underwent treatment in October 2001, at age 43, for subarachnoid hemorrhage. In the case of Stone, the bleeding was actually caused by vertebral artery dissection (VAD) at the base of his skull, rather than ruptured aneurysms. The symptoms and the results were virtually identical to those with ruptured aneurysms, excruciating headaches and bleeding into the brain. Occurs only about one in 10,000 people, VADs are 10 times rarer than brain aneurysm. VADs are caused by a tear in the lining of the vertebral artery.
