I have a wife and we have been married 24 years and she has dementia. I need to know what to do, she sleeps a lot. We watch TV together and she does alright. She does not seem to hear me sometimes and I have her hold my arm to walk ( she takes small steps) and she gets tired easily. We have 2 dogs and sometimes she forgets their names. My question how far along is she and how can I help? Really need help want her as long as I can.
