Cause brain stroke

Stroke Patients are very dangerous, so to find out the cause and prevention of disease effectively.

 

Cause

Cerebral vascular accident can be caused by blockage of blood vessels of the brain (cerebral infarction) or rupture of blood vessels of the brain (cerebral hemorrhage). Some people have temporarily damaged blood vessels of the brain (transient ischemic).

Cerebral infarction: Approximately 85% of strokes are ischemic cerebral brain. Cerebral infarction occurs when the brain arteries narrowed or blocked, causing severely reduced blood flow to the brain. Cerebral infarction include: cerebral infarction due to thrombosis (usually due to atherosclerosis ...), due to embolism (blood clot to the brain usually shoot originating from the heart).

Brain Hemorrhage: Bleeding Brain damage can be caused by multiple cerebral, because uncontrolled high blood pressure, due to a weak position in the walls of blood vessels (aneurysm). A less common cause of cerebral hemorrhage is broken arteriovenous malformation - a major cause of congenital abnormalities of the circuit. The form of brain hemorrhage include: intracerebral hemorrhage, subarachnoid hemorrhage.

Transient cerebral ischemia: It is a mild cerebral vascular accident, due to the sudden decrease in blood supply to part of the brain by a clot or debris clogging cerebral artery, usually lasts a few minutes to 24 hours .  

Risk Factors

Risk factors may treat hypertension (risk of cerebral vascular accident started when hypertension than 120 / 80mmHg), smoking active or passive, increased blood fats, diabetes, fatty obesity, physical inactivity, sleep apnea syndrome, cardiovascular disease (heart failure, congenital heart disease, infection of the heart or heart rhythm disorder), medication (estrogen, cocaine ...), alcoholism.

Other risk factors: family history of the cerebral vascular accident, myocardial infarction or transient ischemic, aged 55 and older, men have a higher risk women.
