I'm posting in chat for traffic.
My dad has suffered from dementia for the last couple of years and is in a nursing home. Other than 'off days' he has remained relatively lucid, normal periods of confusion etc ( he also has heart and kidney disease)
About 3 weeks ago he started to vomit all meals and drinks. Bloods tests done but not showing anything we don't already know. He is physically able to eat but cannot keep it down.
The family know if he cannot keep food or drink down, soon the end will be near and his wishes are not to go to hospital, no drip etc.
Now to my question......he has suddenly become of a very clear mental state, very much having 'full capacity'. However is body is very much failing.
Could this sudden change in his mental condition be the start the death process?
I ask because it doesn't make any sense and we know he isn't going to suddenly get better.
He is late 80's
