When blood flow to the brain is interrupted, a heart attack or stroke can cause death or irreversible damage can occur.
In the world, this disease represents one of the leading causes of death in people over 55 years, and perhaps most importantly, the leading cause of disability or limitation to perform activities of daily living independently. As if this were not enough, it is the second cause of dementia after Alzheimer’s disease.
Cerebral Vascular Event (EVC) can occur when an artery becomes blocked causing disruption or sudden loss of cerebral blood flow (infarction or stroke) or be the result of the rupture of a vessel (hemorrhage or stroke).
But in turn each of them can be caused by different mechanisms, so that each patient is different studies necessary in order to try to establish treatments that reduce the risk of new events. In cerebral infarction or stroke may have several causes, but the most common is atherosclerosis, which corresponds to the deposition of cholesterol and other elements on the walls of blood vessels, which determines the reduction or blockage of blood flow to the brain. Other causes of stroke or stroke originate in the heart with blood clots coming from this point to the brain blocking the cerebral arteries. Cerebral hemorrhage or stroke is caused by the rupture of a cerebral artery, causing bloodshed in the brain. Its main cause is hypertension.
Symptoms to recognize this condition and warn about the urgency of medical care are:
- Numbness, weakness or paralysis of the face, arm or leg on one or both sides of the body and appears suddenly or sudden. To assess this patient may be asked to smile, raise your arms and hold for 10 seconds raised space.
- Sudden inability to communicate either by difficulty speaking or understanding. If you suspect that someone has this alteration it is suggested asking them to repeat a phrase like “Today is a sunny day” to assess whether understands and can produce language.
Other data that may be suspected of a bleeding mainly EVC type or stroke are:
- Sudden onset of headache, high intensity.
- The headache is accompanied by loss of consciousness.
These warning signs may last only a few minutes and then disappear, or can precede a stroke of serious consequences and require immediate medical attention.
A stroke is a medical emergency event. Every minute counts when someone is having a stroke. The longer the interruption of blood flow to the brain, the greater the damage. Immediate treatment can save the life of the person and increase your chances of a successful recovery.
