Before a stroke occurs, the body sometimes sends early warning signals, with the face being an easily noticeable area. Recognizing these signs and acting promptly can help reduce the risk of death and limit long-term brain damage.
Facial drooping or an uneven smile
According to the American Stroke Association (ASA), facial drooping is one of the most common signs of a stroke. Patients may experience one side of their face sagging, difficulty raising the corner of their mouth, or an inability to smile symmetrically.
A simple way to check is to ask the person to smile. If the smile is uneven or one side of the face barely moves, it could signal a stroke risk.
Numbness or loss of sensation on one side of the face
Beyond the limbs, a stroke can also cause numbness or a tingling sensation on one side of the face. Sudden numbness or weakness in the face, arm, or leg, especially when occurring only on one side of the body, is an important warning sign.
Verywell Health indicates that patients might feel numbness, tingling, a crawling sensation, loss of feeling, or unusual heaviness on one side of the face. This symptom often appears suddenly and should not be overlooked.
Slurred speech or difficulty expressing oneself
Facial and mouth muscles play a crucial role in speech. When a stroke disrupts blood flow to the brain, patients may experience slurred speech, difficulty articulating words, or an inability to express what they want to say.
According to Healthline, some patients understand what others are saying but struggle to arrange words or speak clearly. This sign requires immediate emergency care, as earlier treatment leads to a higher chance of recovery.
Uneven mouth, asymmetrical expressions
Timesofindia states that beyond obvious facial drooping, some individuals only exhibit more subtle changes, such as sagging mouth corners, uneven lips, or asymmetrical facial expressions.
This sign can be easily noticed when the person speaks, eats, or expresses emotions. Some cases also involve difficulty drinking water or swallowing food due to less effective mouth muscle function.
Drooling or difficulty controlling facial muscles
According to Medical News Today, damage to the nerves controlling facial muscles can make it difficult for patients to keep saliva in their mouths, leading to drooling or a feeling of losing control over the muscles around the lips. While this symptom does not always appear, when it accompanies facial drooping, facial numbness, or slurred speech, the risk of stroke warrants special attention.
Patients should not wait for symptoms to disappear on their own. Even if the condition only lasts a few minutes and then resolves, it could still be a transient ischemic attack (TIA) – a warning sign of a real stroke risk in the near future.
Experts recommend remembering the FAST rule for early stroke recognition, which includes: F (Face) – one side of the face droops or sags; A (Arm) – one arm is weak or numb; S (Speech) – speech is difficult or slurred; and T (Time) – call emergency services immediately when these signs appear.
Treatment within the first few hours after a stroke can significantly limit brain damage and improve a patient's recovery prospects.
