How aphasia affects the stroke survivor's speech and understanding

Aphasia means the stroke survivor has problems understanding language and speaking. He or she may be unable to find the right words or put sentences together.

Not all strokes cause aphasia.

About 20 percent of stroke survivors have a loss of speech and language. This means the stroke survivor's brain may have problems with:

• speaking
• listening
• reading
• writing
• dealing with numbers.

Just because the stroke survivor has problems using language, doesn't mean he or she can't think clearly. Most people know what they want to say, they just have trouble putting their thoughts into words. It's like when you have a word "on the tip of your tongue."

Some people with aphasia:

• are unable to use nouns or verbs while others have trouble with little words like the and of
• speak easily while others struggle make a sound (Sometimes they are hard to understand.)
• speak mainly in jargon but don't know they are not speaking clearly
• have trouble retrieving the right words they want to say
• know the right words but can't form them with their lips, tongue and teeth
• have problems understanding simple commands and more complex material.
