Chris...
So highly interested in knowing the neuro status of a speech therapist to make these diagnostics / other form of opinion????
Suggest you research aphasias...from global to expressive, receptive, anomia and more... The type can vary by where treatment is practiced...yes, pretty scary...There are various parts of the brain that relate to the various terminology..i.e. Broca's and Wernicke's (sort of opposite sides of brain) ... and, if I remember the anomia is somehow related to a part of the temporal lobe...
On a personal level...as you talk with your mom, suggest you talk slowly, possibly increase sound...and. when she answers...ask, if she means "a quote back" from you...Talking slowly is critical....
When you know, or sense, she is bringing forth a wrong word(s) help walk her back thru it....
What has the speech therapist...or neurologist or whatever...explained to you that may help your mom's recovery?
Also...has your mother's hearing been tested? Were any oximetry (general term for a non-invasive inner ear monitoring) while hospitalized? ...Well, just in case no doc shared this type of info with you...you may want to ask....
Is your mother at home (HHC) with speech therapy, in a rehab facility, or yet in the hospital? If she is at HHC or rehab facility, secure the transfer records....
The records provided to my HHC for a speech therapist noted hearing loss...and, none of my maintained med records do...nor was family told on DC... Conversely...the HHC specialist noted that I had no vision loss...yet, some med records note "call in oph for pt safety"...which was never done...before discharge... or after discharge... until my family insisted on it...tho no referral to neuro-oph...
Worse on the HHC/hospital transfer records...where she notes no vision loss...she also notes about hemianopsia... a major vision issue...
In other words, I suggest you ask a zillion questions...of course, ask those specialists... what has been diagnosed, what has been tested...etc...
I still stumble over words...I did have the global and the anomia...and, some docs elected to call it expressive and receptive aphasias...
Forgive if I have overloaded...
Hugs and prayers for your mother's recovery...
