Slurred speech is a condition where a person's words are not pronounced clearly, making it difficult to understand what they are saying. This can happen for various reasons, such as being tired, intoxicated, or having a medical condition like a stroke or multiple sclerosis. When someone has slurred speech, their words may run together, sound mumbled, or be spoken too quickly. People often notice slurred speech in situations involving alcohol consumption or certain medications. It can also be a sign of a serious health issue, so it's important to pay attention to changes in speech patterns. If slurred speech occurs suddenly, it may require immediate medical attention.
