1. Faiblesse ou engourdissement soudain
Une faiblesse ou un engourdissement soudain, surtout d’un seul côté du corps, figure parmi les signes les plus fréquents et les plus graves d’un AVC. Ce symptôme survient lorsque la partie du cerveau qui contrôle les mouvements ou la sensibilité est privée d’oxygène en raison d’une interruption du flux sanguin. La faiblesse peut affecter un bras, une jambe, un côté du visage ou la moitié du corps.
In practice, this might look like an inability to lift one arm, a leg that feels unusually heavy or unresponsive, or complete numbness that makes it difficult to feel touch or temperature on one side. These changes usually happen abruptly rather than gradually, distinguishing them from other conditions such as nerve injuries or chronic diseases.
Recognizing this symptom is vital because immediate medical intervention can restore blood flow and prevent extensive brain damage. If you or someone else suddenly experiences weakness or numbness on one side, call emergency services without delay.
One arm or leg suddenly feels weak or heavy
One side of the face becomes numb or unresponsive
Difficulty moving one side of the body
2. Drooping Face
A drooping face is a hallmark sign of a stroke and results from muscle weakness caused by impaired brain function. This symptom often presents as an uneven smile, where one side of the mouth sags lower than the other. An eyelid on the affected side may also droop.
Often, the person experiencing this may not notice the change themselves, but family members or friends might observe that their facial expression looks asymmetrical. Even mild drooping should never be ignored, as it indicates that one side of the face is not receiving normal nerve signals.
Prompt recognition and response to facial drooping can significantly improve outcomes by enabling earlier treatment with clot-busting medications or other interventions.
