So cautiously, then, some small improvements.
I have heard from someone who had quite a catastrophic stroke, that it is absolutely exhausting just to "be": afterwords.
Hopefully the next few weeks he'll have more input, feel a little less tired, and the improvements will carry on.
The lady I mentioned was able to do most things, once she recovered, and she worked a way around those she couldn't.
She was an incredibly determined person, and taught herself to use her "good" hand, instead of her pre stroke one.
She could knit, crochet and do cross stitch.
More importantly, she could use a knife and fork, and take care of her personal needs, as well as cooking and gardening.
I hope your man is on the up and up, slowly and surely.
