Everyone thought it was slurred speech. It turned out to be aphasia.

By Eli Mercer on

One thing I've noticed is that many people assume anyone who has trouble communicating must have "slurred speech." It's an easy mistake to make, especially after a stroke or brain injury. But slurred speech and aphasia are actually two different conditions, and understanding the difference can change how we support someone. Dysarthria affects how speech is produced. A person knows exactly what they want to say, but weakness or poor coordination of the muscles used for speaking can make their words sound slurred, quiet, or difficult to understand. Aphasia affects language. Someone may struggle to find the right words, understand conversations, read, or write because the brain's language networks have been affected. Their speech might sound perfectly clear, but the words may not come out as intended, or they may have trouble understanding what others are saying. The tricky part is that a person can have both conditions at the same time. After a stroke, traumatic brain injury, or certain neurological diseases, it's possible to experience both motor speech difficulties and language difficulties. That's why no two people with aphasia look exactly alike. I think this is why it's important not to judge someone's abilities based only on how they sound. A person with slurred speech may understand everything being said. A person with aphasia may speak clearly but still struggle to express or understand language. The communication challenge is different, even if it looks similar from the outside. The more we understand these differences, the better we become at supporting people living with aphasia. A little knowledge can lead to a lot more patience, and sometimes patience is one of the most valuable things we can offer. Has anyone ever mistaken your aphasia or a loved one's for slurred speech? How did you explain the difference?
