Slurring Words (Dysarthria)

Slurred speech, medically known as dysarthria, occurs when the muscles used for speaking become weak, paralyzed, or uncoordinated. This symptom can range from slightly unclear pronunciation to completely unintelligible speech. While sometimes caused by temporary factors like alcohol or medications, sudden onset of slurred speech is a medical emergency often signaling stroke or other serious neurological conditions. The inability to clearly articulate words can be frightening and frustrating, affecting communication and quality of life. Understanding the various causes—from brain injuries to progressive diseases—and recognizing when immediate medical attention is needed can be life-saving.
