I will pray for her.
My mother is 97 and bedridden since 2015. She had a TIA class mini-stroke in July 2016. She didn’t lose anything physically but lost a lot of “connections” (my layman’s term) between various facts and memories. Examples: for awhile she could say the words “mother”, “father”, “brother”, “sister”, “son”, “daughter” but had no real idea how they interrelated or what they meant. For awhile she thought she was her daughter’s sister. With time she has regained some of those connections and remembers people better...to a degree. She knows me on sight now as someone important but still has to be told my name when I first arrive for a visit.
She has lived with my sister for a long time. Their relationship is “complex.” She (my sister) has been very diligent in caring for her and is a bit of a taskmaster in enforcing the various memory drills and physical tasks needed to help her recover and not relapse.
Losing pronouns is common with aphasia strokes. Better to use nouns when talking to her. And slowly.
OH! just remembered. Singing is very good. Uses whole brain. look it up.
