PEG Feeding System for Father with Dementia

I have a 83 yr old father who has moderate to severe dementia. He knows his name and children’s name but does not know dates and can become confused easily. In addition, he also has PLS (primary lateral scrolsis, a derivative of ALS). He has lost the ability to swallow well approx. 4 yrs ago. At that time he chose not to have a PEG system inserted and we did slow personal feedings. Recently he got the flu and aspirated, He is now on life support with pneumonia and mrsa blood infection. He is currently being feed via tube inserted down his throat to his stomach.

My question is quality of life with feeding tube in dementia patients. He will need to be going to a nursing home if he survives this. With his dementia I do not believe that he will leave in the feeding tube nor sit for the long periods of time required to feed. Reading and searching on internet, I have not found much success with feeding tubes in dementia patients.

I am looking for comments from people who have experience with peg systems and caring for a dementia patient. Your comments would be appreciated.
