The VA sent a letter saying he has to be seen by a geriatric dr. Is this first step in getting him into a nursing home?

He is in his home still, i stay here and look after him,not in a medical capacity, just look after him because i'm here. his kids never come here the one only calls every night. he is getting very bad and can't even remember something from an hour or so previously. he complains non stop about me lately to his daughter who tells him not to listen to anything i tell him,because she thinks he just fine. i've talked to her,and tried to explain to her that she wouldn't be able to tell he has ahlztimers/dementia from a few minutes phone call. she encourages him to do as he pleases such as get in the tub when i'm not here,he did and laid there on the floor for more than an hour. i had to get the neighbor to help me again with picking him up. he has dizziness, high blood pressure,no side of his eyes vision and he's got gluacoma in both eyes.he has to take 4 different eye drops every 3 hours. this is in addition to the original cause of his needing eye glasses. he still drives even though his eyes are so bad. he has started having a lot of confusion and hallucinations. i talked to his heart doctor last week about this and the way his family is reacting. that is the only doctor he has,not because of insurance or money just because he flat refuses to get a regular doctor too.even though the heart doctor asked him to. so,i'm hoping that the doctor talked to the V.A. and the V.A. will be able to do something, before he kills himself or someone else with his driving. he spoke to an elderly friend and the friend told him that that letter is to get h thanks for reading and for or any help...
