Types of Stroke
There are two types of stroke. Ischemic stroke occurs when a blood clot stops blood from entering the brain. Hemorrhagic stroke occurs when a blood vessel breaks and causes bleeding in the brain. A transient ischemic attack (TIA) mimics the symptoms of stroke. Although it's sometimes called a mini stroke, it's actually a separate condition.
Despite the danger that it poses, many people are unfamiliar with the warning signs of stroke. Common symptoms appear without warning and should not be ignored. Even if the symptoms turn out to be unrelated to a stroke, it's still wise to seek medical attention. The risk of damage caused by not getting necessary treatment is too great.
People who have already experienced stroke or TIA have an increased risk of having a stroke in the future. If you know that the person showing the following symptoms had a stroke in the past, don’t waste time trying to determine if it's happening again. Call for help.
One of the most common symptoms before a stroke is sudden weakness in the arms, legs or face. This is usually seen on only one side of the body. You might notice that you cannot smile or have trouble moving your limbs.
Another symptom of stroke is sudden confusion. You might be in the middle of a conversation and find yourself struggling to speak or understand what others are saying to you.
Sudden Changes in Vision
Symptoms before a stroke show up in your vision as well. You might lose the ability to see or have trouble seeing in one or both of your eyes. A stroke can also cause blurred or double vision.
