T—Time: If you see any of these signs, call 9-1-1 right away.
Numbness or weakness in the face, arm, or leg, located on one side of the body. Because our brains control each side of the body from a different hemisphere, a stroke usually affects one half of the body.
Confusion or trouble understanding. If you suddenly feel confused and have trouble understanding things you usually have no problems managing, it could be a sign of stroke.
Trouble seeing in one or both eyes. A stroke can affect the area of the brain that manages vision. A sudden loss of vision is another sign of stroke.
Sudden dizziness, trouble walking, loss of balance or coordination. The keyword here is sudden: one moment you’re fine, the next you feel dizzy or have trouble keeping your balance. This is another sign that your brain is being affected by something.
Sudden and severe headache with no obvious cause. A stroke can cause a sudden, very bad headache that doesn’t seem related to your usual headache triggers.
