How do people who have had serious strokes relate to the world?

Mom’s birthday would’ve been the 10th; I guess that’s what’s prompting this question today.

During the year between her second stroke and her passing, she was unable to talk. On her better days, it seemed like there was potential for her to communicate more clearly—but that never really happened. (One speech therapist said that she’d just accepted her new reality and wasn’t really trying anymore, but who knows for certain?)

I’ve wished since before her passing to understand how she might have perceived the world post-stroke. Allowing for individual differences and conditions, does anyone have an insight as to what it might be like?
