The mother in law was no longer receiving any speech therapy, due to insurance limitations. The mother in law was fully aware of what was being said to her, but she could not respond with words - this is expressive aphasia. It seems that most of the family is okay with this situation.
The woman I spoke to wanted to do more for her mother in law, but was confused on what options were available.
There are many options available. My first suggestion was to find an Aphasia Support Group.
Let me know if you have other suggestions.
