What are the warning signs of a stroke?

Stroke is a disease that affects the arteries leading to and within the brain. It is the No.5 cause of 

death and a leading cause of disability in the United States. A stroke occurs when a blood vessel

that carries oxygen and nutrients to the brain is either blocked by a clot or bursts(or ruptures). 

when that happens, part of the brain cannot get the blood(and oxygen) it needs, so it and brain

cells die. Every year, more than 795000 people in the US have a stroke, about 610000 of these are

first or new strokes. About 185000 strokes-nearly 1 of 4 -are in people who had a previous stroke.

About 87% of all strokes are ischemic strokes, in which blood flow to the brain is blocked.

Yet, despite these dire statistics, stroke is preventable, treatable, and beatable. It is necessary to

understand some of the precursor symptoms of stroke so that treatment can be carried out as 

soon as possible to avoid more serious consequences.

The symptoms of stroke precursors include sudden darkening of the eyes and inability to see things.

Generally, they will return to normal after a few seconds or tens of seconds. This is the most common

symptom of stroke precursors in middle-aged and elderly people. This is due to the retina caused by

cerebral ischemia. The phenomenon caused by ischemia, if the precursor appears, must be treated in 

time to prevent the occurrence of stroke.

The symptoms of stroke precursors also include slurred speech, which is caused by the insufficient blood

supply to the brain. Insufficient blood supply to the brain will cause the patient's motor function and nerve

failure. The most common symptom is slurred speech, or even inability to speak. Speaking usually lasts for 

a relatively short time. This phenomenon must be paid attention to. At the same time, it may be accompanied

by symptoms of skewed mouth and tongue. These all require attention.

The best way to prevent stroke is to reduce the intake of fat and salt, pay attention to a balanced diet, avoid

overeating, and maintain a normal weight, keep your emotions smooth.
