If you suddenly find it hard to speak clearly, it could be a sign that a stroke is approaching. Sometimes this happens because the muscles used for speech are weakened, making your words sound slow, unclear, or slurred. In other cases, the stroke disrupts the brain’s ability to process language, making it hard to find the right words or understand what others are saying. This symptom often appears alongside weakness or drooping on one side of the face, which can make speaking even harder. Any sudden change in speech should be treated as a medical emergency.
