Anyone else have a loved one on extended hospice?

I am in a similar situation. My 81 year old mom came to live with us do to memory issues. Because she was so thin I took her to see her Pcp...Severe emphysema in both lungs, stage 3 nsclc, and mild dementia. She was put on hospice in July of 2014. Her decline is extremely slow. Because of the dementia she does not remember the cancer diagnosis. I wonder if that is what keeps her going. Her dementia is now stage 5, well into the moderate stages.  In my opinion the dementia is what she will eventually die from not the cancer or the COPD. Her Drs gave her 6 months to live 2 1/2 years ago. Her only continued symptoms are a cough and getting winded on exertion. She won't do oxygen or her nebulizer. Like I said, very slow decline.  She is happy and taken care of living each day as it comes in her dementia world. She shouldn't be here but she is so all I can say is it's all Gods timing! Blessings!
