In America, about 795,000 people suffer strokes each year—which means that one person has a stroke every four minutes.
Thankfully, research on strokes has begun in earnest in recent years, but there is of course still much to do.
One way to help is to donate money to more research, but learning the warning signs is also vitally important—because every fifth stroke patient shows warning signs 24 hours before the episode actually occurs.
Stroke is an umbrella term for cerebral infarction and cerebral haemorrhage. The brain’s nerve cells are dependent on nutrients and oxygen through a network of blood vessels, and strokes often occur as the result of a blood clot, which totally or partially clogs some of the brain’s arteries.
The symptoms often come suddenly, but many people feel that something is wrong long before the actual stroke.
1High blood pressure
Many people with high blood pressure don’t feel anything at all—but high blood pressure is the single biggest risk factor for both cerebral infarction and cerebral hemorrhage.
High blood pressure can damage the small blood vessels in the brain, causing them to narrow, rupture or leak.
If you suspect you have high blood pressure, contact a health center, writes the Mayo Clinic.
