The tiredness is normal and when your husband becomes tired he should rest because it is part of the recovery process.
Every stroke is different but they are always debilitating, the thing for your husband to do is to maintain a positive outlook, try to find methods to work around or overcome any difficulties and try to regain as much functionality in hs limbs as he can, use it or lose it as the physio's will say.
Recovery is a slow and gradual process and short term memory loss would not be unusual ( I put my 'senior moments' down to my age).
It can help to write down things to remember, I have to write down the names of people who I have met to avoid the embarrassment of forgetting them on our next meeting
Your husband should try hard to practice his mental agility, puzzles, jig saw puzzles, books, draughts or chess, even snakes and ladders or tiddlywinks can help in this respect because manual dexterity is combined with thought process - win/win.
Is there a support organisation such as a stroke club near to where you live? Your husband would benefit from meeting other people who are in a similar position to himself, some will be better but some will be worse and meeting and speaking to others who have suffered strokes can help to regain some perspective on the situation and can reduce the possibility of depression
