Replying to Alzheimer's

sometimes we have to laugh at our battles right? i'd like to..

well my grandma who i love so much has alzheimer's and its gotten to the point i can't stand her.
what she is donig to my family is horrible (and im not really blaming her, i know its the disease)
she calls all the time yelling at us for various things... and if we don't pick up she calls (and leaves a message each time) untill we do... she thinks we stole her car.. and calls my dad a theif... she yells and yells ... doesn't take her medicine that would help her so much (and lies that she did)
it hurts my dad so much i can't stand it... and this is only a little tiny bit of what she does.. its so horrible i could never understand it before...

but enough about me... does anyone else have experiance with alzheimer's?

any stories... of things people have done?
anything funny? cuz you have to admit some of the things it makes people do you have to laugh at...
on the other side... anything that can help deal with it?

any responses would be so great
