Been through two of them with my dad (76).
He dodged a bullet with the 1st - no outwardly detectable side-effects, and fully recovered in about 4 weeks.
The 2nd was much rougher. He had nearly full paralysis of the left side. After 6 -8 weeks of re-hab, then/now about 6 months of day to day living, he’s back to about 90% function.
Stroke = brain death. Depend on the extent & location of the damage within the brain, there is usually a very good chance the person with “re-wire” themselves. (Different areas will take up the load, and learn new tasks). There will always be some loss, somewhere.
Now more than ever you’ll need to keep a close eye on your mom. The secret to survival in a stroke is very prompt medical attention. I can’t recall the drug, but there is a medication that when administered within a short time-window (like 90 minutes) that works wonders. This is what was used on my Dad.
(This may not apply to your Mom, but alcohol / alcoholism throws a HUGE wrench into the works. Both times with my Dad this caused difficulties with recovery. Just when he was stable from the stroke injuries, the DT’s & withdrawal from alcohol took hold. This started a whole new battery of medications/sedations… I hope this isn’t your situation).
Knowing more about something usually helps:
