Stroke
A stroke happens when blood and oxygen cannot reach the brain because a blood vessel is blocked or breaks open. Brain cells start to die and can result in brain damage. A stroke may cause the loss of brain-controlled activities, such as speech, movement and memory.
People who suffer a small stroke may have minor problems later, like weakness in an arm or leg. On the other hand, people who've had a major stroke may be paralyzed or lose their ability to speak. Some people get better, but many have problems that last forever.
A stroke is a serious condition and needs to be treated right away. Quick treatment lowers the risk of long-term problems or death. Get to know the symptoms including:
- Numbness or weakness in the face, arms or legs
- Trouble speaking, confusion or difficulty understanding others
- Trouble seeing in one or both eyes
- Dizziness, problems walking, or having a hard time standing up
- Severe headache
