Aphasia vs Apraxia

What is the difference between Aphasia & Apraxia?

If you were a car radio, Aphasia would cause difficulty finding the broadcast station's signal and Apraxia is difficulty with the speakers that make the sound.

• Aphasia can generally affect all four of the language areas (reading, writing, listening, speaking)  but people usually mean Expressive Aphasia which impairs the retrieval or "recall" words. It's as if you still have all the words in a mental dictionary but you've lost the index. I call it "tip of the tongue syndrome" because it feels like words or just on the tip of the tongue. You know what you want to say, but can't think of the word.
• Apraxia impairs the ability to speak the words clearly because the mouth muscles don't work quite right.  So even if you hear the word you'd not be able to repeat it back.
