1. Facial drooping
Facial drooping is one of the most recognizable and immediate signs of a stroke. It occurs when the muscles on one side of the face become weak or paralyzed, causing the face to appear uneven or sagging. This happens because a stroke disrupts the brain’s control over facial nerves, leading to loss of muscle tone.
In practice, a person experiencing facial drooping may have difficulty smiling evenly or may notice that one side of their mouth or eyelid appears to be drooping. This symptom often appears suddenly and can be confirmed by asking the person to smile or show their teeth.
- Look for uneven facial expressions.
- Check if one eye or mouth corner droops.
- Note if the person cannot raise both eyebrows equally.
If you or someone you know suddenly develops facial drooping, it is critical to seek emergency medical care immediately as this may indicate an ischemic or hemorrhagic stroke requiring urgent intervention.
2. Arm weakness
Arm weakness is another crucial stroke warning sign. It usually affects only one arm, reflecting the stroke impacting the opposite side of the brain that controls motor function. This weakness can range from mild difficulty in lifting or moving the arm to complete paralysis.
To test for this symptom, the individual can be asked to raise both arms simultaneously. If one arm drifts downward or cannot be lifted, this is a strong indicator of stroke-related arm weakness.
Arm weakness during a stroke results from interruption of blood flow to motor areas of the brain, leading to loss of strength and coordination. Immediate medical evaluation is necessary to prevent permanent damage.
- Ask the person to raise both arms.
- Observe if one arm drifts downward involuntarily.
- Note any inability to hold the arm up or perform simple movements.
