Determining signs of a stroke

Stroke is a serious health condition in which the brains cells die suddenly due to the lack of oxygen. Rupture of artery which feeds the brain or any kind of obstruction in blood flow can result in a stroke. In the United States alone, 140,000 are killed by stroke every year. So, knowing the signs of a stroke is very important.
If a person smiles and the smile is crooked, it might be a sign of an oncoming stroke. Also, if the person’s face appears stiff or paralyzed on one side during a smile, it might be a stroke. When a person cannot lift one of his hands as high as the other, there might be some motor function problem leading up to a stroke. Other signs of a stroke are trouble walking, speech problems, dizziness, loss of coordination, loss of balance, double vision, blurred or blackened vision and severe, sudden headache.
