To speak, messages must go from your brain to your mouth. These messages tell the muscles how and when to move to make sounds. When you have apraxia of speech, the messages do not get through correctly, due to brain damage. You might not be able to move your lips or tongue the right way to say sounds. Sometimes, you might not be able to speak at all.
Apraxia of speech is sometimes called acquired apraxia of speech, verbal apraxia, or dyspraxia. It is a motor speech disorder. You can also have apraxia in other parts of your body, like in your arms or legs. This is called limb apraxia.
How severe your apraxia is depends on what type of brain damage you have. Apraxia can happen at the same time as other speech or language problems. You may have muscle weakness in your mouth. This is called dysarthria . You could also have trouble understanding what others say or telling others what you are thinking. This is called aphasia .
Children can also have apraxia. This is called childhood apraxia of speech .
If you have apraxia of speech, you will have problems saying sounds correctly. This may cause you to say something very different than what you meant. You may even make up words. For example, you may say "chicken" for "kitchen." Or, you may say something that might not make sense, like "bipem." You may know that what you say is wrong and try to fix it. Sometimes you will get it right, but sometimes you will still say something else. This can be very frustrating.
If you have apraxia, you may:
Damage to the parts of the brain that control how your muscles move causes apraxia of speech. Any type of brain damage can cause apraxia. This includes stroke, traumatic brain injury, dementia, brain tumors, and brain diseases that get worse over time.
If you have trouble speaking, you should see a doctor right away. It is important to find out why and make sure it does not get worse. A speech-language pathologist, or SLP, can test your speech and language. This will help the SLP decide if you have apraxia or some other problem. The SLP will look at how well you can move your mouth, lips, and tongue. She will listen to how your speech sounds in single words, sentences, and conversation. The SLP will test how you understand what others say and how you use words to tell others about your thoughts.
The SLP can work with you to improve how you say sounds and put sounds into words. Treatment will focus on getting your muscles to move correctly. You may need to retrain your muscles to make sounds. Repeating sounds over and over and practicing correct mouth movements can help. You may need to slow down or pace your speech so that you can say the sounds you need to say. In severe cases, you may need to find other ways to answer questions or tell people what you want. These may include simple hand gestures, writing, pointing to letters or pictures, or using a computer. This is called augmentative and alternative communication .
