<human>: Hi /r/relationships,

I'm a somewhat prominent member of this sub, but for personal reasons, I would like to keep my identity hidden. I hope that you indulge this throwaway account.

My father has level 4 Alzheimer's, I'm not exactly sure what that means nor am I up on the technical/medical jargon, it's not really my area of expertise. I am told that he has loss of judgement and is unable to properly digest extremely emotional issues. Sometimes you can see the real him in his eyes, other times he is just not there.

His younger brother has terminal cancer and has been placed by loved ones in a hospice. My mom does not know if she should tell my dad, or wait until my uncle dies and tell him then. I have a mind to involve my dad's sister (70's F) whose husband also had Alzheimer's, she may have a better perspective.

If you have any advice or personal experience in this, it would be greatly appreciated.

Can you give me a shortened version of the text?
