Recognizing Stroke Symptoms Quickly
A stroke is a medical emergency that occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. Brain cells begin to die in minutes. A stroke can be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel (hemorrhagic stroke). Some strokes are preceded by symptoms called transient ischemic attacks (TIAs), which are brief episodes where stroke-like symptoms occur but disappear within 24 hours.
Warning Signs of a Stroke
The ability to recognize the signs and symptoms of a stroke is crucial for prompt medical intervention. The most common warning sign is sudden numbness or weakness in the face, arm, or leg, especially on one side of the body. Other key indicators include:
- Sudden confusion: difficulty speaking or understanding speech.
- Severe headache: a sudden and severe "thunderclap" headache.
- Trouble seeing in one or both eyes: vision problems, double vision, or loss of vision.
- Difficulty walking: trouble with balance or coordination, dizziness, or loss of coordination.
Common Indicators of Stroke
The acronym FAST (Face drooping, Arm weakness, Speech difficulty, Time to call 911) is a well-known mnemonic for identifying common stroke symptoms. Additional indicators include:
- Numbness or paralysis in the face, arm, or leg, particularly on one side of the body.
- Confusion: trouble understanding simple statements, difficulty speaking clearly, or slurred speech.
- Dizziness: sudden onset of dizziness or loss of balance.
- Vision problems: sudden blurred vision or loss of vision in one or both eyes.
Identifying Early Stroke Symptoms
The early signs of a stroke can be subtle and may not seem immediately alarming, but they are critical. These symptoms include:
- Sudden weakness or numbness on one side of the body, especially in the face, arm, or leg.
- Difficulty speaking or understanding speech: slurred speech, trouble forming words, or difficulty understanding spoken language.
- Dizziness or loss of balance: sudden onset of dizziness or unsteadiness that may cause falls.
- Sudden severe headache with no known cause: a "thunderclap" headache that peaks within minutes.
