Stroke is the No. 2 cause of death worldwide, which means it’s important to know the warning signs. Remember F.A.S.T. (face drooping, arm weakness, speech difficulty or slurred speech – if you see any of these signs, it’s time to call 911). Other signs that someone is suffering from a stroke include sudden vision loss, a severe headache (caused by swelling in the brain), dizziness or imbalance, and nausea and vomiting (both of which are very common early signs of stroke). By understanding what to look for and taking the signs of stroke seriously, you could save a life!
